Covered with a film that performs decorative and protective functions. If handled carelessly, scratches may appear on it. To eliminate minor scratches, you can use laminate wax. If they are not very deep, you can repair the window sill using a special Cosmofen cleaner, this is a solvent-based composition. Apply the product to the scratches, the top layer of the film will dissolve and become liquid, the scratches will simply disappear. But in the case when the window sill has already turned slightly yellow from time to time, it is better to cover its entire surface with this product so that there are no stains.

When choosing a manufacturer of plastic windows, please note that some companies include in the contract the condition for replacing the window sill in case of damage.

When the scratches are deep or someone managed to burn through the window sill with a random cigarette butt, it will not be possible to remove it with a solvent-based composition. In this case, Cosmofen Plus liquid plastic can be used. It will help even in cases where a dent has formed from an accidentally placed hot pan or pan. Liquid plastic simply fills all the recesses, and the relief of the window sill becomes even and smooth again. But, since such a plastic patch will be noticeable, a special decorative self-adhesive film can be glued on top of the window sill.

In hardware stores you will be offered decorative self-adhesive films imitating the surface of natural stone or wood of various species, you can always choose the one that suits your design.

If the window sill lost its former appearance or was damaged, it was usually necessary to remove it in order to replace it with a new one. To do this, it was necessary to dismantle it, which was accompanied by damage to the wall. Now there is no need to replace and dismantle the window sill. Some companies offer special window sill trims made from the same PVC as the windows. There are imported and domestic linings on sale. Imported, as a rule, are pasted over with a decorative film. The surface of some overlays is not glued at all, which significantly increases their strength to mechanical stress and their service life. The overlay completely covers the upper surface of the window sill and its end, plugs are installed on the sides, the window structure acquires a finished and aesthetic appearance.

One of the main elements of the window opening is the window sill: thanks to it, the window looks neat, the room receives additional protection from heat loss and precipitation, and fresh flowers can be installed on the surface.

When may window sills need to be repaired?

Restoration work may be required in the following cases:

• The surface is covered with cracks, chips, scratches or scuffs, which not only worsens the appearance, but also the performance of the product. Most often, this element suffers from excessive mechanical stress.
• Deformation of a surface that can buckle or deteriorate when exposed to elevated temperatures.
• Burnout of the surface from ultraviolet radiation. Constant exposure to sunlight leads to fading, which is especially noticeable on a product that does not have the classic white, but a different shade or pattern.
• If the product is made of wood, it may be damaged in contact with moisture, and in this case, the restoration of the window sill or its complete replacement may be required.

• Cleaning the surface from dirt, sealing cracks, degreasing with alcohol.
• Preparation of the lining, cutting the product to the size of the window sill.
• Applying glue or mounting compound to the surface, installing the lining. After that, a press is placed on it and the structure is left until the glue dries. This will take 1-2 hours.
• The gap under the lining is filled with sealant, the ends are masked with plugs.
• After the glue dries, the film is removed from the top of the lining, which protects the coating from mechanical damage and chemicals.

Repair of window sills made of wood includes the following steps:

• Removal of paint residues, puttying in case of cracks, chips and scratches.

Which is better: repairing plastic window sills or replacing them?

Many owners are wondering if it is worth repairing the product if you can buy a new one. Recovery is cheaper and takes less time when it comes to minor damage. A complete replacement is usually carried out if the product has significant defects, and it will not be possible to restore it with full preservation of operational properties (strength, durability, etc.). In addition, the repair of plastic window sills has the following advantages:

Conclusion: if you want to understand how to repair a plastic window sill, you just need to get a minimum set of tools and strictly follow the instructions. The procedure takes a minimum of time and allows you to return the item to an updated appearance.

Modern plastic windows with double-glazed windows are distinguished by aesthetic beauty, durability and good thermal insulation. But often with improper installation or poor-quality manufacturing of the windows themselves or their fittings, all pleasant impressions disappear.

Many owners of plastic windows faced the problem of constant accumulation of dust on the window sills inside the apartment. Together with dust, cold air is also blown into the apartment in winter and heat is vented from the apartment. At the same time, a slight draft of cold is felt in the apartment.

Being next to such a window, a slight breath is felt from the window; it is blown through. The main reason for these inconveniences is the gap between the inner window sill and the window frame itself. Moreover, this gap may not form immediately. The reason for its occurrence is construction debris, dust and the protective plastic film of the window sill, which many window installers do not remove when pulling the window sill with the frame, as well as the greed of the craftsmen who saved on foam under the street window sill. In addition, due to the constant blowing of the plastic window, which means that it is supercooled, condensate may form on it, which will drain into the same slot. And since there will be moisture in this gap for a long time, mold can start there. And if a hard frost hits. then the condensate in the slot may freeze, which will lead to the fact that under the pressure of ice the slot will increase much more and the blow will become even stronger! After installing the windows, these shortcomings will no longer be possible to eliminate on their own without removing the frame or window sill. Especially during the cold winter...

The space and voids under the outer window sill are usually sealed with mounting foam. But this is not always enough for thermal insulation. Foam tends to crumble under the action of sunlight, it does not always fill the entire space, mice, bats and various insects easily destroy it by building their homes in it.

There are two ways to deal with this gap.

1 WAY

For work we need:

1. can of silicone sealant (I used KIM Silicon 101E white to match the window frame) with a gun
2. stationery knife
3. a couple of flathead screwdrivers
4. plastic profile "Layout for tiles 9-10mm inner corner" (matching the color of the window frame)

To begin with, the plastic profile must be cut along the length of the window frame with a margin of + 2-3 cm. Then cut off the perforated plate from the profile. In the diagram, the part to be cut is highlighted in gray, the cut line is indicated by a red dotted line. When cutting off, you need to maintain a distance of 8-10mm from the right of the curved plate, and at a distance of 1-2mm from the bend at an angle of 90 degrees (indicated in the photo with a black marker).

I cut off the excess from the profile with a clerical knife. The cutting line may turn out to be a curve, but this is not so important. The cut off part with perforations can be thrown away. On the second part of the plastic profile along the cut line, it is necessary to carefully scrape the cut corners on both sides with a clerical knife. giving them a slightly pointed shape.

Now you need to make small holes in the corners of the window sill, where in the future we will insert the edges of the prepared profile. The gap between the window sill and the frame must be cleaned of plastic film and construction dirt with a knife. In places where the gap is not very large, you can use a flat screwdriver. Perhaps in this case you will stir up the plastic and the gap will increase. but it will do us good.

After the window sill should be thoroughly washed and wiped dry.

After preparing the window sill and frame, using a spray gun, press a little sealant along the entire length of the window into the gap between the frame and the window sill. Outside, also along the entire length of the window, evenly apply a layer of sealant to the corner between the window and the window sill. It is also desirable to apply evenly and a little sealant to the plastic profile.

After applying the sealant, first insert one end of the plastic profile into the prepared hole in the wall at a distance of 1-1.5 cm (for this, a margin of 2-3 cm was made when the profile was cut to length) and insert the pointed edge of the profile cut line into the gap between the window sill and the window until it stops .

Insert the edge of the profile along the entire length of the window, and reaching the second edge of the profile. fill it into the second hole in the wall and into the gap. It is possible that excess sealant will squeeze out. It must be carefully assembled without smearing. If the profile in some places does not fit snugly against the frame or window sill. it needs to be pushed a little more into the slot with the help of an elastic one. but not a solid object. Using a hard object, you risk damaging the smooth surface of the plastic profile.

After the final stripping and wiping of the sealant, you will get a miniature one. careful. a beautiful, moisture-resistant and durable corner instead of a through crack!

The photo clearly shows how the plastic insert protects the gap under the window from getting condensation from the windows. Now everything is sealed and beautiful! Do not forget to putty and paint the holes into which both edges of the plastic profile were inserted.

2 WAY

The second way is simpler and cheaper. But the resulting gap-covering surface will not be as strong, and will be subject to contamination over time.

For the second way to eliminate the gap, you only need a sealant. several coins of different denominations and a knife.

As in the first method, the frame and window sill must be cleaned of debris and protective polyethylene. The gap must be cleaned and rinsed with water and wiped dry.

Press as much sealant as possible into the gap to seal the gap. After that, generously apply the sealant with a gun in the corner between the window sill and the window frame, forming an evenly distributed sealant sausage.

To give the sealant an even shape, use a coin. for example, a coin with a face value of 10 rubles (g). Swipe the edge of the coin, pressing it against both the frame and the window sill. You can experiment with coins of different diameters, different radii will allow you to form different sizes and thicknesses of the sealant surface. By pressing down, the excess part of the sealant will be cut off. and in places where it will not be enough spent. Excess will accumulate along the corner above where the coin meets the window and sill. They don't need to be cleaned right away. but only after a frozen film forms on the surface of the sealant and it becomes like jelly. You need to swipe the coin at one time, without stopping and at a uniform speed. The neat rounded surface formed under the edge of the coin will look like a plastic profile, considered in the first method of eliminating the gap of plastic windows. The main thing is not to rush to clean off excess sealant! In the same way, you can create a curly sealant profile in this corner - then you will need to use any solid object with the shape you need instead of a round coin.
