How to fix platbands on interior doors yourself. How to install platbands on interior doors Do-it-yourself installation of platbands for interior doors

How to eliminate the gaps after installing the doors and give them an aesthetic appearance? For these purposes, specialists use platbands. Their main function is to hide defects and cracks that appeared during installation. Platband installation interior doors- this is a responsible process that requires experience and skill from the master.

What are cashiers

The construction market is represented by a wide range of overhead slats. They differ in:

• functions performed: constructive, decorative;
• color scheme;
• shape: flat, rounded, curly;
• texture: simple planks, carved frames made according to patterns;
• sizes;
• installation method: overhead, telescopic;
• material: wood, metal, aluminium.

Finishing should be selected based on personal preferences, as well as taking into account the features of the interior, the exact installation site. When buying platbands, it is important to correctly determine the material. Any type of raw material has its pros and cons.

Wooden

Ten years ago, this view was the only option for decorating a door. But, despite the improvement of the construction industry, it is up to today is in demand. The main advantage is versatility: wooden planks are suitable for any type door structure .

They may differ from others in their appearance. Depending on the taste of the consumer, the decor can be carved, with figures of various shapes.

The lack of wooden architraves on the door is the need to update them. But this is not a reason to refuse them. Modern platbands are made in such a way that they can be easily restored, puttied, applied paintwork.

MDF

Most people compare this material with fiberboard. On the one hand, they are similar in properties. On the other hand, in the production of MDF, Newest technologies providing higher quality material.

MDF architraves are suitable for installation outside wet areas

MDF is a fibreboard with medium density. According to the degree of environmental friendliness, it is the same as a tree. And veneered MDF is even outwardly difficult to distinguish from it.

Overhead planks made of MDF are preferred because of their low cost and durability. But when choosing, it must be borne in mind that it has poor moisture resistance. Therefore, it is not recommended to install it in rooms such as a bath, a toilet.

Plastic

These boards are made from durable plastic, which is not subject to changes under the influence of climatic factors. During operation, they do not fade, do not melt. In addition, they do not require special care. Wet cleaning once a week is all you need.

Plastic platbands are highly moisture resistant

Due to the low price, good resistance to moisture, plastic trim has found a wide range of consumers. However, there are negative points.

The disadvantage of this decor is a small selection of models, as well as colors. Usually white and several shades of brown are sold. Platbands of other colors are made to order.

Trim cutting methods

The appearance of the cashing depends on how carefully the master cuts the components of the structure. You can cut in several ways using:

• end electric saw;
• chairs, hacksaws.

To make the cut as even as possible, without chips, roughness, experts recommend using a professional electric saw. In this case, the device must be in good working order. If the saw blade is crooked, dull, or there is even a slight runout of the bearing, the result will be far from desired.

With the help of a professional saw, you can get a perfectly even cut.

However, you need to know that even high-tech equipment of well-known brands allows small errors. For them, there are certain tolerances: the angle washed down - 0.3-0.7 degrees, the inaccuracy of the joint - from 0.1 to 0.5 mm.

Who refuses to buy an electric saw can use the factory miter box. It is a tray made of metal, plastic or wood. With this tool, products are cut at different angles: 90, 45, 30 degrees.

Home craftsmen most often use a miter box

For cover strips made of different materials select the appropriate blade. Metal, plastic frames are cut with a hacksaw for metal, wooden - with a hacksaw for wood. From the right tool depends on the quality of the work done.

Ways of fastening platbands

Installation is carried out with finishing, liquid nails, self-tapping screws, "beaks".

With finishing nails

This type of fastener has found wide application due to a number of advantages:

• stealth;
• ease of installation;
• does not require experience.

For work, take thin nails about 4 centimeters long, up to 1.5 millimeters in diameter. The distance between them should be 50 cm. Points are marked on the rails with a simple pencil.

After fixing, the nails can be puttied to match the color of the wood, so that the nails will not be visible.

In places of marks, nails are driven in so that they enter the box by 20 mm. If the hats are narrow, then they can be left or, if desired, cut with side cutters. The resulting small depressions are masked with a wax pencil of a suitable color.

The disadvantages of working with finishing nails are:

1. Difficulty of dismantling. Due to the peculiar structure of the cap, it is almost impossible to get nails.
2. Less strong connection than conventional nails.
3. When choosing this method of fastening, also keep in mind that such nails are intended for finishing where there is no bending load.

liquid nails

This method is ideal for MDF framing. It is performed quite simply, does not require certain skills, dexterity.

For the installation of MDF platbands use liquid nails

Liquid nails are applied on the wrong side of the decorative element and attached to the wall. For the glue to grab, you need to hold it for a few minutes, and then fix it with tape.

This type of fastener is good because it leaves no marks on outside rails. However, the fastening strength is not as high as when using ordinary nails.

Fastening with self-tapping screws

This method is characterized by reliability. It is used for wood products.

Wooden architraves fix with screws

Even a beginner can handle a self-tapping screw construction business. To do this, you just need to follow the instructions:

1. Find self-tapping screws with a diameter of 6 millimeters, a length of 2 centimeters.
2. On the front side of the slats, put marks 50 cm wide from each other.
3. Drill small holes in the indicated places, and then drill them out a little. This will hide the heads of the screws.
4. Screw in the screws. If desired, they can be disguised under putty or decorative overlays.

Fastening with "beaks"

The "beak" was nicknamed the platband, which outwardly resembles the Russian letter "G".

This method is very simple. It lies in the fact that the most large plot parts are placed in a recess specially designed for this and snap it into place.

The disadvantage of fastening with "beaks" is the gradual delamination of the structural element. Under the influence of the fastening itself, the strips begin to collapse at the junction points. As a result, there is a need for additional fasteners with glue.

Docking methods

There are 3 mounting methods.

Docking angle 45˚

During installation, it is impossible to do without trimming the sections in which the individual parts of the kit are connected. A 45 degree cut is the most commonly used. It is ideal for any type of finish, successfully hiding cut areas.

45˚ joint hides cut areas

The platbands are connected at an angle of 90 degrees. The top trim board is placed between the right and left sides.

Docking at 90˚ with simulated jumper

This installation method is used to create unusual design interior.

Great for historical imitation

Installation instructions for wooden architraves

You can make a door trim not only with the help of a master, but also with your own hands. To avoid mistakes, strictly follow the algorithm.

Stage 1. Preparatory work.

With a construction knife, clean the surface of the doorway from the protruding polyurethane foam. Then walk with an even rail around its entire perimeter, look at the position of the wall and the box. Existing problems will be solved during the installation of the frame.

Step 2. Mark the location of the overlay strips.

The overlay strips are installed in such a way that the rounded corners of the door frame remain visible.

Platband installation

And the straight lines from the side of the extension should coincide with the corners of the decorative element.

Pay special attention to the fact that the platbands do not interfere with the operation of the hinges, the lock "screwdriver" of the door. Attach the planks and mark with a pencil above the box above the joint angle at a distance of approximately 3 mm. The indicated places show the height of the vertical and the width of the horizontal elements of the decor at the lower docking corners.

Sometimes, during installation, dobors receive numerous damages. To hide them, experts advise putting marks on the door elements two millimeters below the corner. If there are no defects, then install the strips to them flush.

Step 3. Attach vertical strips to the marks and mark them at the desired height.

After measuring the platbands, number them and put the numbers on the wall in the appropriate place. This will allow you not to confuse them in the process of work.

Step 4. Cut the vertical parts of the structure at an angle of 45˚.

The cut should be even, without chips. When cutting, consider the kerf width as it can be up to 3 mm in some tools. Therefore, make an appropriate indent from the label.

Trimming of vertical strips is done taking into account the width of the cut

Step 5. Attach the vertical and then horizontal elements .

First fix the vertical bars, and then the horizontal ones.

Installation instructions for plastic trim

To make your own plastic trim, strictly follow the scheme:

Due to the fittings, the joints look beautiful, so there is no need to use sealant to close the gaps.

Aligning the plane of the casing with the wall

Our builders do not always adhere to standards, so there are many shortcomings. One of the most common are curved walls. What to do when the wall and the box are not parallel to each other?

If the error is very small, then it is not difficult to solve the problem. For this you need:

• Press the decorative rail against the box, measure the size of the gap that appears between it and the wall. If it is not more than 3 mm, then the disadvantage is eliminated without special construction work.
• Find a narrow lining. It should be the same thickness as the gap. Put it on the desktop of a saw or miter box. The lining will lift one side of the casing during washing down.
• Press the patch bar as tightly as possible to the work table, cut the end at an angle of 45 degrees and with a slight slope in relation to the surface. Thus, the joint of the overhead strips will be sealed and sealant will not be needed to eliminate gaps.

The situation is worse if there is a large error between the wall and the door frame. Then you will have to eliminate it in one of the following ways:

• Dismantle the wall, make a niche for the frame if the box is deeper than the wall surface. To do this, attach the overhead strips to the box, draw lines along the wall along them. Then, using a grinder, cut this line, make grooves around the entire perimeter of the door. Constantly check their depth. If the niche turns out to be deeper than necessary, seal it with a cement mortar.
• Correct the deficiency with a planer if the purchased planks of wood are too thick.

Installation of finishes is a troublesome business, but you can’t sacrifice anything to create home comfort.

Door platbands are designed to mask the gap between the doorway and the door frame. They are selected according to the required texture and width, and the color is chosen exactly the same as that of door leaf. They are made from different materials and are divided into wooden, plastic, laminated, MDF and veneered. The work of mounting them is the last step in installing the door. By the beginning of these works, all other repairs, except for installation floor plinths, should already be completed. This article will discuss how to make and how to properly install door trim.

Types of door frames

Today, the construction market is filled with platbands of various shapes: carved and figured, teardrop-shaped and semicircular.

They play the role of finishing decoration of the door. Some sellers, in order to visually reduce the price, indicate the cost of only the canvas and the box. But having started to install, out of ignorance it turns out that there are not enough platbands, and you can buy them in addition only for a fee. Therefore, even when buying a door, you must definitely check their availability in the configuration. Of course, the price of door frames is quite affordable, but another problem may arise when buying - color matching. It will not be difficult to choose the necessary shade of trim for a painted or laminated door, but for a wooden or veneered door it will be extremely difficult.

The standard width of the door trim is 7 cm, thickness - 1 cm, height - 210 cm. For an interior door with one leaf, 5 trim strips are required, and for a door with two leaves - 6 strips.

If you only need to frame the doorway, then two and a half planks are enough. In addition, manufacturers produce door frames of any size in width, height and thickness.

Tip: when choosing platbands for interior doors, their color should completely match the color of the door leaf. And when choosing a frame for the entrance metal door, from the inside, the shade is selected according to the color of the walls of the corridor.

Door platbands are made of MDF, plastic, natural wood, aluminum or steel. As decorative coating laminated film, veneer, facing plastic or paint composition is used.

What is a telescopic platband?

Outwardly, it looks like a regular door casing, but has a ledge for connection with extensions and a door frame. Their use is most optimal if the door frame is a couple of centimeters narrower than the thickness of the wall. Thanks to a special protrusion, it is tightly fastened in the longitudinal grooves of the end of the door frame.

With proper installation, the fasteners become completely invisible, which gives the whole structure a look of solidity, durability and strength. But if the distance is incorrectly calculated, the casing will not fit tightly into the box and there will be a gap. The design will immediately acquire an ugly and untidy look.

What is a capital?

The capital is a relatively recent decoration of the door. Although their main function is exclusively door decor, they also belong to the category door architraves.

In most cases, they are made of solid wood or MDF. They are produced in various shapes and decorated with curly ruffles. The capital is made in both standard and non-standard sizes. After their installation, the door takes on a rich and finished look.

How to make door frames

Today, the construction market is represented a large number of all kinds of door frames. They differ not only in material, but also in size and color. You can also make them yourself at home, this will reduce the cost of repairs. But in order to make high-quality platbands, you will need special woodworking tools and at least a little experience working with such equipment.

Below is a list of tools that will facilitate the work on the manufacture of platbands. Some of them can be replaced with a planer, but thereby increasing labor costs.

Required tools:

• sawmill for the manufacture of blanks;
• planer to create a right angle;
• thickness gauge to achieve the required thickness of the workpiece;
• a vertical milling cutter to create a pattern (not needed if the casing is simple without a pattern);
• electric grinder and milling cutter;
• auxiliary tools: squares, rulers, pencils.

Material selection

The board for platbands is selected only well-dried, otherwise it will lead over time. The degree of drying is determined by the sound. To do this, they tap on it with a finger, if the sound is deaf, this means that the board has not yet dried, and if it is sonorous, the material is ideal for work.

In addition to sound, when choosing a board, you should pay attention to its color.

It should be uniform, and blue spots mean that the drying technology has been violated. In the future, they can be hidden only by painting with opaque paint.

The surface of the board should not have knots. This not only worsens its appearance, but also increases the risk of fracture of the finished clypeus in this particular place.

Manufacturing

Selecting material and preparing essential tool, you can start making door trim. First, blanks are cut required dimensions, which are calculated individually for each door. It is worth noting here that the quality result directly depends on how sharply sharpened cutting knives on machines and machines.

When the platband is ready, it is polished. This is done in two stages: the first is rough grinding electric machine, the second - manual processing with fine-grained skins. At the second stage, all circular scratches left by the electric machine should be removed. The finished platband is covered with a protective compound.

How to fix door frames

In total, there are four main ways to fasten door trim: using finishing and liquid nails, on self-tapping screws or on special fasteners called "beaks".

Finishing nails

This is one of the most popular ways. It has a number of advantages: if necessary, the platbands are easy to dismantle and reinstall, and the fastening process itself is simple and reliable.

To fasten the platbands, nails with a flat, narrow head are selected. It is not difficult to calculate their length, they should enter the door frame to a depth of 1.5-2 cm. The average length of finishing nails for platbands is about 4 cm.

Tip: if you can't buy flat-head nails, you can cut them with side cutters.

To facilitate the work, points for fastening are pre-marked on the platbands. They are placed at an equal distance from each other along the entire length of the bar. The main thing here is to maintain the right balance, it is often not recommended to place them, but too rarely is also bad. Experts advise keeping a distance of 50 cm.

Liquid Nails

They are a special glue in tubes. Mounting on it is very simple, the glue is simply applied to the casing from the reverse side immediately before mounting. Then the bar is pressed tightly against the wall, held for several seconds, after which it can be released. Everything, the platband is installed.

The advantage of this method of fastening is not only in the simplicity and speed of work, but also in the fact that there are no traces of fastening on the front side of the platbands. The disadvantage is the complexity of its dismantling and not too much reliability of fastening.

Self-tapping fastening

Due to its simplicity and reliability, this method is gaining more and more popularity. For wooden platbands, wood screws with a diameter of 6 mm and a length of 2-2.5 cm are used.

Places for self-tapping screws are pre-marked on the platbands. After that, small holes are drilled, which guarantees further excellent result and protect the wood from splitting when screwing the screw.

Tip: for less visibility of the self-tapping screw head, it is “recessed” into the wood, having previously drilled a small recess.

Special mounts "beaks"

Their advantages are good appearance, easy installation and operation. But there is also a significant drawback. Most architraves are made of MDF, and when removing the "beak" there is a chance that it will delaminate.

How to install door frames

To install wooden platbands you will need:

• wood saw;
• fasteners (finishing nails and glue)
• goniometer;
• roulette.

Stages of work

• First, the platbands are applied along the height of the door, and the required length is measured. Then the bar is placed on a flat surface and a right angle is marked with a square. The excess is cut off;

• a platband with a ready-made corner is applied to door frame, aligned at the edges and bottom. The height corresponding to the internal rumble of the door frame is noted;
• then, starting from the mark made, an angle of exactly 45 degrees is measured with a goniometer and marked with a pencil. The excess is cut off and the casing is temporarily set aside;

• repeating the entire sequence, the parallel side is marked;

Tip: the top trim is prepared last, only after both side strips have already been cut and installed. This will prevent errors in marking and exclude the possibility of the formation of cracks at the junction.

• after both side trims are cut off, their installation begins. Carnations are driven into the door frame, after which, with the help of wire cutters, the hat is removed from them, leaving a sharp corner. The length of the stud on the surface for installing the casing is approximately 5 mm;
• nails are hammered with a distance of about 50 cm. Usually they are placed at the top, bottom and two in the middle;

• for better adhesion of the casing to the box, glue is applied to it. At this stage, the main thing is not to overdo it, and when pressed, the glue should not squeeze out;

• when nailing the bar to the door frame, it is not recommended to hit it directly. For this purpose, a wooden block wrapped in cloth is prepared;
• having attached the finished casing and leveling it, with strong blows through the bar we put it on nails;
• when both side platbands are installed, the marking of the top one begins. Both of its 45-degree angles are measured not by a goniometer, but by directly applying it over the side planks and drawing the cut point with a pencil.

Door frame installation completed.

Nuances when installing platbands

The presence of a nail or self-tapping screw can be made invisible with a wax corrector or acrylic sealant of a suitable color.

To avoid gaps in the joints of the platbands, the angles of the upper bar are measured according to the cuts of the vertical bars, taking into account their errors.

It happens that the platbands at the junction have a discrepancy. This is due to the unevenness of the walls or the curvature of the planks themselves due to improper storage. Fixing this is quite simple, just connect the planks together with a finishing nail.

If minor gaps are found, they are masked acrylic sealant or wax corrector of a suitable color.

When there are significant defects around the box, a wide door trim is suitable for masking them. Its width is 10-12 cm, and with individual order maybe even more.

If you are wondering how to glue the trim, then you can choose from several options. With perfectly smooth walls, liquid nails are used. Also, for additional fixation when installing on nails, acrylic glue or PVA is used, which lubricates the back of the casing. But it should be noted that there is only one really reliable fastening - on carnations.

As mentioned above, the installation of door frames is final stage all repair work. The platbands are mounted flush on the end, and visually it seems that on the wall. The most popular method of fastening is on thin carnations with a small hat. In the event that the platbands need to be fixed directly to the wall, liquid nails are used, but this method of fastening does not give a long-term guarantee.

For an interior door, the platband should be 10 cm higher than the doorway. The standard installation of the platbands is done with a cut at 45 degrees, but you can also do it at an angle of 90 degrees - it looks a little unusual.

If the opening in the wall is located on the side or is in contact with an adjacent wall, then the platband will not fit completely. It will be possible to cut beautifully in width only with an electric end saw. Accuracy for the platband is especially important, because its main role is decorative ornament and masking all the irregularities of the wall and the end of the door frame.

But there are cases when platbands are not needed, for example, a bathroom whose walls are tiled. They will not only look out of place there, but it will also be impossible to attach them. The only one possible way fasteners are liquid nails, but given the high humidity of the room, they will not last long.

For very wide (thick) walls, door frames are also not the best option. In this case, the slopes can simply be painted, wallpapered or plastered. Also, in most cases, door frames are not required when installing compartment doors.

Platbands - decorative element door structure, performing an aesthetic function. The task of these overlay strips is to create a frame that covers construction defects and gaps between the wall plane and the door frame. The installation of platbands on the door does not differ in particular technological complexity, but being the final decorative touch, it requires scrupulous accuracy and knowledge of the nuances of sawing and fastening from the performer.

Types of platbands and methods of their fastening

To cash out the door frame, the owner of the bath can use molded products made of wood, MDF or plastic. Carpenters are advised to give preference to laminated or veneered MDF products or PVC platbands, which practically do not react to steam and temperature fluctuations.

Mounting material and specifics:

• Wooden platbands can be installed on "liquid nails" or fastened with thin nails without caps. Hats can be cut off on their own or fastened with a construction gun that “shoots” with studs without them. When using nails with hats, the fasteners are slightly “drowned”, and the locations are masked with wax corrective pencils or acrylic sealants matched to the tone. The use of adhesives is acceptable, but will create problems if it is necessary to dismantle for cable laying or for the next repair. Liquid nails are applicable only in the case of perfectly aligned walls, otherwise there will be gaps between the casing and the wall to be finished.
• Outwardly, MDF platbands are practically indistinguishable from wooden counterparts, but their fastening is carried out according to special rules. In order not to damage the planks, the guide holes for the nails are drilled on them in advance. The holes are not through, a diameter of 1-1.5 mm is preferred. MDF, just like wood, can be simply glued.
• Platbands made of plastic prefer to be glued. Their cost allows you to dismantle cashing without regrets and the desire to reuse. Flexible plastic moldings can be glued to walls with minor irregularities.

Choice of cutting angle for joining

The angle is determined by the presence of a shaped relief with front side. At the disposal of home craftsmen who figure out how to install trim on doors, there are two options:

• Planks with a flat surface without a shaped form can be cut down at right angles. The same is done if the door is framed with platbands with a capital. The direction of docking can be either horizontal or vertical. Before installation, saw cuts are painted or tinted with varnish.
• Embossed moldings, platbands with a rounded surface are cut down at a standard angle of 45º. This is the most common scheme that requires strict adherence to the rules and accuracy. The result of the slightest flaws will be unattractive cracks.

In order to ideally cut the workpiece at an angle, you need to stock up on a miter box and hand saw with small teeth. A flawless edge will turn out if the owner saws on trimming machine equipped with a turntable.

Features of telescopic architraves

Buyers of doors produced by a number of domestic factories are given the opportunity not to use fasteners at all when installing platbands with a patented telescopic design. The happy owners of Volkhovets or Sofya products will not need additional additions, since the correction in case of vertical deviations and in case of discrepancy between the size of the box and the width of the opening is carried out by adjusting the telescopic door frame.

Details on how to install doors with telescopic architraves, their owners will learn from the manufacturer's instructions, since each of them has its own technological schemes. A feature common to all is the presence of a protrusion-slot, which is introduced into the groove on the box. Connections are recommended to be strengthened with liquid nails.

Step-by-step work technology - measurements and installation

It is recommended to start framing the doorway with platbands:

• after completion of wallpapering;
• when equipping doors with platbands on both sides after pasting two adjacent rooms;
• before laying the plinth.

You need to start work on the side of the door structure into which the canvas opens. That is, in terms of location door hinges. The reference point for measurements will be the bar that closes the box from the side where the hinges are located, since because of them the platband is not installed flush with the box. This indent should be equal on all three lines. For fastening platbands on the back of the door, it is not necessary to indent.

So, the order of work:

• With maximum accuracy, we measure the length of the vertical bar installed next to the hinges. The distance resulting from the indent is added to the length. The point obtained as a result of measurements will be the beginning of the line along which the excess is cut off from the workpiece at an angle of 45º.
• For the manufacture of the opposite casing, measurements are made in the same way, but separately. Not the fact that the distance from the floor to the required point will be equal.
• Sawn planks are baited with two nails. We fix one of them at the base, the second about a meter later.
• Under the unfixed upper ends of the vertical platbands, we place a blank for the upper bar. We mark on it the points required for flawless sawing at a 45-degree angle, saw off with a miter or simple mechanical saw.
• We fix all three components.

The base of the door frames usually rests on the floor, but sometimes a kind of bedside table-stand is placed under the door frame.

The step of installing studs or nails is determined independently. Carpenters recommend driving in galvanized or copper nails every 15 cm if lovers of slamming the door actively use it. With careful operation from an aesthetic point of view, the optimal step is 50 cm.

If the sawing angle is somewhat disturbed, gaps will inevitably appear at the joining points. Those who did not manage to avoid this due to inexperience do not need to despair. Failures can be masked with sealant. To do this, on both sides of the gap on the platbands, you need to stick a regular mounting tape. Preferably in several layers. Then fill the gap acrylic composition suitable tone.

We bring to your attention a quick way to accurately markup:

Correctly executed installation of platbands of interior doors guarantees considerable savings. Cash out in the same way entrance doors, however, the platbands are fixed mainly only from the inside, since the outer frame is already on the box. The work is not difficult, but meticulous, and without knowing the nuances, you can ruin a lot of material. By the way, carpenters advise inexperienced home craftsmen who want to become more adept in this direction to start with the most dimensional opening, so that in case of failure, the planks could frame a smaller door. Well, having gained practical experience, you can take on complex tasks.

Door frames are made from natural wood, laminated MDF board or plastic. Each material has its own advantages and disadvantages; a specific type of platband should be selected taking into account the specific installation site, general interior space and personal preference. In terms of price, they differ slightly, but the difference is not so significant that it has a decisive influence during the choice.

There are several ways to fasten the casing, depending on the angle of the connection.

Docking with cutting ends at an angle of 45 °

The most common and most universal way. Allows you to completely hide the places of cuts, looks beautiful.

Docking with cutting ends at an angle of 90 °

A very simple method, it has two options: the open ends of the cutting are located vertically or the visible ends of the cutting are located horizontally.

Docking with cutting ends at 90°, elongated horizontal trim with imitation of a bridge

It is rarely used and only to create exclusive interiors.

The platbands can be fixed with special thin nails with a reduced head diameter or without it. Professionals work with a pneumatic gun, but you should not buy it for one bath. The length of the nails is within two centimeters.

The second way of fastening platbands is with the help of liquid glue. Both methods are equivalent from the point of view of builders, each can be used with the same quality of installation of platbands. small advantage use of glue - there are no visible places of fixation. But the heads of carnations can also be drowned a little and painted over with a building marker of the appropriate color.

Trim cutting

It is better to cut the moldings with a special electric miter saw. The saw table is installed under different angles, the cut is perfectly even, there are no chips and roughness. Such a saw is relatively inexpensive, and during the construction of a bath it will always come in handy. If necessary, it can be disconnected from metal table and use as portable tool– very convenient for any construction site.

Electric miter saw - photo

Important. When trimming the trim, check the serviceability of the tool.

The saw must be sharp and even, even the slightest beating of the bearings of the electric saw is excluded. Firmly press the side edges of the moldings to the persistent surfaces of fixtures or tools, the presence of even the slightest gaps will create big problems for you during installation.

No desire to buy it? Then you should buy a factory miter box or make it yourself. The miter box allows trimming moldings at an angle of 90°, 45° or 30°.

You should not buy a Chinese low-quality miter box. They make it from recycled polyethylene, and during cooling it shrinks a lot, the position of the thrust planes changes. We advise you to check the device before starting work. Saw off several blanks in various positions, join them together with cuts and check the angles.

Let us consider in more detail how to install both plastic and wooden or MDF trim.

Installation of wooden or MDF platbands with sawed ends at an angle of 45 °

Step 1. Preparing the surface of the doorway and trim

With a construction knife, carefully cut off the protruding mounting foam, do not damage the door frame during cutting. Be especially careful when working near the visible corners of a box pasted over with a self-adhesive polyethylene film.

Check the position of the plane of the wall and the box. Take a flat rail and check the position of the wall and frame around the entire perimeter of the doorway. If there are problems, then you will have to solve them during the installation of the platbands. How this is done, we will describe below. The ends of the lower part of the architraves must be cut off - during transportation or long-term storage they could be damaged.

For one door you will need four long and two short architraves. You need to saw off with a margin of length 3 ÷ 4 centimeters.

Step 2. Mark the position of the architraves

The door frame has rounded corners, a right angle only from the extension side. We recommend placing the platbands in such a way that the rounding does not close. From the side of the extension, respectively, the corners of the casing must exactly match the corners of the extension.

The platband should not interfere with the opening and closing of the door

Important point! The platband should not interfere with the operation of the door hinges and the “response” of the door lock. Attach the trim to the door frame and make marks on the top of the box with a thin pencil. They will be located 2÷3 mm above the joint angle of the door frame. These marks indicate the height of the long vertical architraves and the width of the short horizontal architraves at the bottom corners of the joint.

On the side of the extension, we recommend placing the marks on the architraves 1÷2 mm below the corner, this will allow them to completely cover the irregularities or damage to the surfaces of the extensions. If the extensions are in good condition, then you can put the platbands flush with them.

Do the markup slowly

Step 3. Attach vertical platbands to the marks and make marks on them at a certain height

Step 4: Cut the vertical architraves at a 45° angle

Don't give a big pitch cutting tool, the cut should be as even and clean as possible. When cutting, take into account the width of the cut, in some saws it can be up to three millimeters. Depart from the mark made by the width of the cut.

Step 5. Start nailing the prepared platbands

First, two vertical ones, and then a horizontal one.

Stud caps can be sunk a little and sealed with acrylic sealant to match the color. The same sealant can be used to seal gaps around the entire perimeter. installed platbands and the door frame and in the corner upper junctions of the cuts.

Important. The use of sealant to seal cracks indicates a low qualification of the performer. If you do not have enough experience, then it is better to practice a little with gashes than to eliminate the marriage later. Nail the first platbands from the inconspicuous side of the doors, get some practice.

There may be problems due to the fault of the builders of the bath, we will consider some of the ways to eliminate them. Most often, the plane of the wall does not lie in line with the plane of the door frame. The door frame is either too recessed, or vice versa, protrudes too much, or even slanted. In this regard, the platbands cannot fit snugly against the doorway, large gaps appear in the corners of the joint, regardless of how accurately the cuts are made.

There are several ways to solve such rather unpleasant problems.

Aligning the plane of the casing with the wall

First way. The simplest, but, unfortunately, not always applicable. With it, you can correct the non-parallelism of the planes of the wall and the box within 2 ÷ 3 millimeters. How it's done?

Step	Description
Step 1.	Put the platband in the intended place, firmly press it to the box. It will move away from the plane of the wall a little, estimate the width of the gap between it and the wall. If it is within 2 ÷ 3 mm, then the gap at the junction is removed without the need for construction work.
Step 2	On the working table of the saw or miter box, place a lining of the same thickness as the size of the gap. The lining should be narrow, not the entire width of the casing, only a few millimeters, it should only slightly raise one side of it during washing down.
Step 3	Firmly press the casing to the desktop in this position, the lower plane of the casing on the side of the stop should rise slightly above the table. Carefully cut off the butt at the desired position. The cut end should have 45° to the axis and be with a slight slope to the surface. Now, in the “broken” position, the junction of the two platbands in the places washed down will be tight, you will not have to close the gaps with acrylic sealant.

Way two. Due to a violation of manufacturing technology, wooden platbands may have uneven surfaces or warping. Of course, ideally, their quality should be checked at the time of purchase. If the marriage was discovered already in the process of installing the platbands, then warping is easily eliminated. Position the vertical and horizontal architraves so that the notches lie flat. Drive a carnation into the end, it will fix them in the correct position and prevent them from moving.

1. The door frame is too recessed into the wall. We'll have to chisel the wall - the work is dusty, noisy and dirty. Place the casing against the box and draw a line on the wall. Using a grinder with a diamond blade or saw (depending on the wall material), cut a line along the wall. And then you need to choose a niche for the casing. You can do this with a grinder, a chisel, etc. Constantly check the depth of the groove. If in some places the niche turned out to be too deep, close the recess with gypsum or cement mortar and immediately put the casing in the desired depth position for a few seconds, this will help you make the niche more accurately. So you need to go around the entire door around the perimeter.
2. If you have a casing made of natural wood and has a decent thickness, then you can remove it a little with a planer reverse side. Work very carefully, do not rush, it will be impossible to correct the mistake.

Installation of architraves with cutting ends at an angle of 90 °

Cutting the ends of the trim at an angle is rare; such a door does not look very nice. This can only be done by completely inexperienced craftsmen. It is better to make open ends of the cuts on top of the vertical trim, in this place the incised end is hardly noticeable.

Slices in without fail skinned with fine sandpaper. Sanding should be done carefully so as not to damage the laminate on the front surface of the casing. Places of cuts need to be painted over with carpentry markers under the main color. All other operations, except for the angle of washing down the ends, do not differ from those described above.

During the fastening of the platbands with liquid glue, they should be kept in the desired position for several minutes. Carefully monitor the accuracy of the connection at the joints. Irregularities in the wall or problems with the quality of the architraves can widen the gap. To prevent this from happening, first fix the joint angle with a carnation or put linings under it, taking into account the size of the gap between the casing and the wall. Only after that you can press the casing to the entire surface and wait for the liquid glue to cool.

Nail the first nail in the middle of the casing, this will allow you to turn it a little for a tight connection in the corners of the gash. Only after the corners on all sides of the door have laid down as they should, you can drive in nails to fix them. The distance between the nails is approximately 15÷20 centimeters. You need to check the distance by lightly tapping on the casing. You will immediately find out in which places there is a loose fit of the casing, drive additional carnations into them.

If during hammering the nail did not reach the end and bent - do not pull it out. Gently pinch the rest with pliers, rotate it left/right until it breaks off. Why not take it out? The nail could not be hammered in for a “good” reason beyond your control, which means that the second one will not completely enter this place either. It is much better to immediately hammer in a new one next to it, there will be fewer holes in the platbands.

It is possible to increase the tightness of the platbands across the entire width with polyurethane foam. Apply it on the back of the architraves in a thin strip along the entire length from the side of the wall, allow three to four minutes to partially dry. Otherwise, the foam will not adhere to the surface. Next, arrive the platbands in the recommended way. After the mounting foam has completely dried, carefully cut off the visible part, the gap can be sealed with sealant. Although, if you do not overdo it with foam, then it should not act. During pressing, the ability of the foam to increase volume is significantly reduced.

In conclusion, we will give practical advice on working with an air gun. It is designed in such a way that there are air outlets on the side. The piston is constantly lubricated with engine oil, during the exhaust of air, its smallest particles come out. When the studs need to be driven into the end of the platbands, an oily stain from the outgoing air always forms on the white wall. Be sure to place clean paper between the gun and the wall.

If you have cash white color- do not oil the nails, the oil will leave a stain at the entry point of the nail.

Installation of plastic platbands

In some cases, plastic platbands are difficult to distinguish from natural ones; in terms of their performance, they satisfy most owners. You can choose any color scheme, thickness and width. Connecting elements included corner cuts, mounting and front profiles.

How to install them?

Step 1. Mark the mounting profile

The mounting profile is plastic product with special protrusions-latches for the front profile. The marking of the mounting profile does not need to be done very accurately, it subsequently closes and becomes invisible. The cuts in the corners of the platbands can be with a distance of several millimeters, the gap does not play a critical role. The distance is removed, as described in the above section on the installation of MDF and wooden architraves.

Step 2. Cut the blanks of the mounting profile

You will need four long vertical and two short horizontal ones. Cut at a 45° angle. You can use an electric saw for trimming, a device for cutting at an angle (miter box) or an ordinary grinder with thin disc for metal. The mounting profile can be shorter than the front one by 5 ÷ 10 millimeters. This makes sizing easier.

Step 3 Fix the mounting profile to the wall

Self-tapping screws are used for fastening.

Very important. The mounting part of the casing can not always be referred to as a box, especially a thin Chinese one, and its installation on the wall requires the ideal quality of the latter. The best way– the walls are made of drywall, sheet plywood or OSB boards. Plaster is the worst option. If the quality of the plastering "wants the best", then you will have to trim the strip near the door frame with a spatula. Otherwise, the profile will bend in waves during pulling, and this is unacceptable.

The mounting profile is fixed with self-tapping screws in special seats. If you need to screw in the screws more often - not a problem. Drill a small entry hole in the plastic and screw in the screws. That's what some masters say. We advise you not to drill any special holes, the self-tapping screw is already screwed in perfectly. You need to start by fixing the center of the profile, the screws are screwed along the edges only after checking the position and correcting errors.

Step 4. Dimension the front profile, taking into account the thickness of the connecting elements of the corner cuts

In most cases, their thickness does not exceed two to three millimeters. But there is also much wider, it all depends on the manufacturer of the platbands. Dimensions are taken from the floor to the corner of the box.

Step 5. Saw off two vertical trims at an angle, fix them in the mounting profile

One of the advantages plastic architraves– the front profile can be shifted in the mounting and in this way precisely adjust its position. It is advisable to first install only vertical platbands.

Step 6. Insert the connecting profiles into the sawn ends of the front vertical platbands

File one end of the horizontal face profile and insert it into mounting profile. In this position, measure the place of sawing off the second end. Immediately keep in mind the thickness of the connecting profile.

Step 7: Cut the face profile at a 45° angle and insert it into place

In the hidden cavities of plastic platbands, you can mount electrical, telephone or Internet cables. Thanks to the corner fittings, the joints always turn out very neat, it is not necessary to use sealant to eliminate gaps.

It is better not to install plastic platbands on walls sheathed with clapboard. If you really want to, then you need to prepare ahead of time for this. Before installing the door frame along the perimeter of the doorway, a wooden lath with a thickness of approximately 0.5 ÷ 1.0 cm should be nailed. It must be carefully nailed into the convex places of the lining profile. Make sure that the slats do not bend in waves. During the installation of the door frame, it must be equal to the level of the rails. On the opposite side of the door frame, the alignment is done by an extension.

We do not recommend purchasing factory-made boxes for a bath, they do not differ high strength, during prolonged contact with water can completely lose their bearing capacity. In addition, the factory boxes are very narrow, in most cases you need to install additional trims. It is much more profitable to buy only door leafs in the store, it is difficult to make them yourself. And you can make the boxes yourself, while you immediately choose desired width make them stronger and more durable.

Able to significantly decorate the interior of the room, they can be made both from natural wood (the most expensive option), and from plastic or MDF. Plastic decorative platbands have a complete set of additional elements that simplify the installation process. With wooden ones you have to tinker.

Their installation begins with washing down the upper corners. When taking measurements, you need to keep in mind not only the position of the trim in relation to the door frame, but also the combination of patterns. Some platbands have special technological places to facilitate the combination of patterns, and some need to be selected very carefully. Especially a lot of problems can arise during the docking of the upper and side trim. If you have little experience with such complex work, - better not take it. Do not waste time and money in vain.

How to fix the trim on the door - this question often becomes relevant when carrying out repairs in the house. Doing it yourself is actually quite simple, if you know some of the nuances regarding the types of products and methods for fixing them around the perimeter of the opening.

There are several ways to fasten door frames.

The main types of platbands

Before we look at how you can attach trim to interior doors, you should familiarize yourself with their main types. The method of installation directly depends on the specific type of product.

According to the material of manufacture, they distinguish:

• wooden;
• from pressed paper;
• metal.

Varieties of door platbands depending on the material of manufacture

For budget options pressed products are used. AT modern interior MDF products are the most popular type, besides, unlike other types of platbands, any mounting option is available for MDF.

By appearance and configurations are:

• straight;
• rounded;
• carved and figured;
• typesetting.

Variations of platbands by configuration

Additionally, a capital can be installed above the upper casing. This element plays an excellent decorative role, especially when it comes to classical style and variations close to it.

With regard to mounting methods, platbands can be installed in three main methods:

• on ordinary nails;
• on glue "liquid nails";
• according to the "thorn-groove" principle.

In order for the opening to look organic, it is important to observe the optimal dimensions for all details. Cutting elements can be done in two ways: at a right angle or 45 degrees. In the first case, the upper bar is most often installed above the sidewalls, while it must have an edge processed. With an oblique cut, you need to bring out the ideal angle so that the fragments fit together without gaps. For cutting it is better to use a miter box.

Before proceeding directly to fastening the platbands, you should prepare properly work surface. The entire list of works can be conditionally divided into several stages:

1. Box installation. The platbands serve as a kind of decor for doors, as they are able to create a spectacular frame and hide minor wall defects. Consequently, their installation must be carried out at the very end after the doors are installed.
2. Foam removal. After the box dries, it is necessary to cut off the excess mounting foam in order to bring an even level between the wall and the loot, it is best to do this with a clerical knife.
3. Removing irregularities. If, during the installation of the door leaf and the box, small defects appeared on the wall, for example, concrete chips, they can be repaired with plaster, this will not only facilitate installation, but also improve the strength of the opening. To ensure that no gaps remain during the installation process, the surface for attaching the platbands must be flat.
4. Wall decoration. Before installing the platbands, it is necessary to complete all finishing work: painting, wallpapering, etc.
5. Cleaning. Remove all dust and other debris from the surface; when using glue, you must additionally degrease the perimeter of the opening.

Preparation of the working area for the installation of the door trim

Use of nails

The most traditional way to install architraves is to use nails. In order to hide the attachment points as much as possible, special miniature carnations are used, their feature lies in the almost complete absence of a hat.

In order to properly nail the platbands on the door, you need to set them according to the level. Since when mounting on a wall, distortions or gaps can occur that were not on a flat surface, it is recommended to leave a small excess of material when sawing.

Since nails without hats are used for platbands of interior doors, try not to damage the coating of the cladding itself. It is most convenient to work with a small hammer. You can pre-mark the connection point with an awl.

In order to cover the nails on the platbands, they mainly use a special mastic or grout to match the coating. Minor damage can be masked with paint, felt-tip pen or pencil.

Use of nails traditional way architraves fastenings

Liquid Nails

Another method of fastening platbands involves the use of special glue. The most popular option is the so-called liquid nails. This compound provides fast traction on almost any surface.

Let's consider how to properly fix the platbands without ordinary nails. To do this, you must initially determine the exact position of each element. After that, apply a small amount of glue to the back of the plank and press it against the wall. If glue comes out from under the casing, wipe it off immediately. It is advisable to apply only a few dots to prevent spreading.

You can fix the platbands either completely without nails, using glue, or by combining these two methods, this will provide greater structural strength.

Fastening platbands to liquid nails simplify the process

Telescopic models

The simplest is to attach telescopic architraves to interior doors. It is performed without nails, but can be supplemented with glue for greater strength. Mounting features are directly related to their design. The fact is that the edges of the platbands, when connected, coincide with the edge of the extension or loot. The principle of adhesion is "thorn-groove".

Telescopic platbands are mounted strictly in the groove of the box plank

In other words, one part goes inside the other. Thus, in order to install such products, it is enough just to saw off the excess and dock the parts. The protrusion of the element is inserted into a recess in the door frame. Then you need to set required distance, which is regulated by the size of the recess.

Regardless of which installation method you choose for a particular situation, care should be taken, as one awkward movement can ruin the entire structure. If there are irregularities on the wall, it is necessary to first align them so that there are no gaps, this applies to absolutely all models of platbands, regardless of the material of manufacture and configuration.
