Form for an artificial stone from sealant. DIY silicone molds for artificial stone are a simple solution for complex finishes. Acrylic cold curing stone

I thought I would not write an article about making molds, since I did not plan to do this. But the stone is not bought as often as we would like, so we decided to make molds for sale. And there is one good reason for this: people search the Internet for both stone and shapes. And if a person wants to make a stone himself, he will buy and make them, but he will buy from others, so we did not miss such a source of additional income, especially since no one sells molds in our city. So, today we'll talk about how to make quality form for artificial decorative stone with your own hands. We will do it using the example of a silicone compound, there will be many photos and many useful information which few people will tell you about.

Matrix manufacturing

If anyone does not know what a matrix is, this is the whole “construction” into which silicone or polyurethane is poured. The matrix will require a piece laminated chipboard and bars about 2 by 2 cm. I found chipboard in the trash, someone will say “fu”, but I’m not dumb, I drove up in a car and loaded it into the trunk and that’s it, and it’s free. Instead of bars, I used parts from the cabinet (they also lay in the trash), they are varnished and are great for making molds: the silicone will be better separated from them.

As a basis, I took a ready-made polyurethane purchased form, but decided to make the sides thicker, since silicone has several times less strength than polyurethane and it can tear when bent.

Polyurethane mold

Gap 1cm

I want you to pay attention to how to join the “bars”. You need to try to make sure that there are no gaps between them and chipboard. If you are unable to do so due to lack of good materials, then when screwing the bars to the chipboard, the connection can be smeared with ordinary silicone, otherwise the compound will leak out.

Joint without gaps

For manufacturing we need:

Silicone compound;
Catalyst (comes with the compound);
Grease.

Model set =)

I used wax release agent VS-M. Instead, you can use ordinary petroleum jelly, before using it you need to warm it up a little and smear it with a brush over the master models, but more on that later.

So, there is a formwork on which you need to glue the master models.

formwork

The next step is gluing the tiles to the chipboard, but first I want to tell you how to prepare these same tiles.

Preparation of master models

Before making a mold, you need to think about how much area you want to get it and count the number of tiles. In my case, the form has an area of 0.25 square meters. meters in which 24 tiles. Tiles for the form must be chosen of the highest quality: without “shells” and pimples.

Pimples on the master model

The quality of the form will depend on which master models are used and how they are fixed. It is necessary to fix it, otherwise, when pouring with a compound, they may move, as we did for the first time.

As you can see, some of the boards are thick and others are thin. This is because the tiles were not glued to the matrix.

I also advise you to look at the back side of the tiles, because. it may be slightly curved.

curved backside decorative stone

If you neglect this and pour it as it is, then the compound will flow into these slots and you will be tormented then remove the finished form from the matrix, and then you will still have to cut the sides, and this is extra work.

Gluing master models

In order to evenly glue the master models and make all the sides the same, I decided to make markings directly on the chipboard.

markup

Now you need to glue the tiles to the chipboard, for this we take the usual silicone sealant(cheapest) and apply it to the edges of the tiles, as shown in the photo.

Apply silicone sealant

Glue.

Gluing tiles

As you can see, the silicone has come out on the sides, it needs to be removed. I scraped it off with a regular screwdriver. It turned out like this.

We do the same with the rest of the tiles.

Our matrix is ready!

Now you need to give the silicone time to dry. Then we take the lubricant and apply it on the surface in 2 layers with an interval of 1-2 minutes. Lubrication is needed so that the mold can be easily removed after drying.

As I wrote above, you can use ordinary petroleum jelly, before using it you need to warm it up so that it is better smeared. I haven't tried it, but I've seen a few videos of it being used.

We are waiting for the grease to dry a little. Then we put our matrix by level.

Filling with compound

Before pouring, the compound must be mixed well, because. there is usually a thick sediment at the bottom. It is better to mix with a wooden stick, it will not scratch the jar and there will be no plastic strips in the solution. After mixing, add the hardener and mix thoroughly again. The mixture will become more fluid. Then, directly from the jar, we pour the resulting solution over the matrix. You need to pour in a thin stream and first of all you need to fill all the recesses.

Highly frequently asked question: how to calculate the amount of silicone or polyurethane per matrix? So, we take a ready-made matrix with glued tiles, fill it with dry gypsum. Then we pour the gypsum into a container, put it on the scales and measure the weight. For example, you got 3 kilograms, it turns out that the same amount will be needed for the compound. Of course, this is not an overly accurate way, but I don’t know another, if anyone knows, then write in the comments.

Here's what happened.

ёёёёёёOn the site the site has already posted an article on how to make an artificial stone for a summer residence with your own hands. There are quite a lot of interesting details, except for one - how to make molds for this material. About it right now.

Impossible to complete quality stone without forms in which it is necessary to fill in a solution of a certain composition. We also mentioned some recipes earlier, as well as the production technology itself, and therefore today we will only talk about molding containers.

Where to get a mold for artificial stone

By by and large, this is the easiest question so far. Why? Yes, only for the reason that such products are sold in any building supermarket. The only problem is that not everyone has such a supermarket nearby or it is not always possible to get to it quickly. But, in this case, the problem is also not solved, because in order to obtain the materials for the production of the form, in case you want to make it yourself, you will also have to look for a similar supermarket.

That is, there is only one question - to buy a form or make it yourself. Let's just say that independent production not cheaper in any way, well, maybe for a penny, and then only if you make several products at once. Then why, as they say, bother? This is a matter of honor for a summer resident who is ready for complete independence, well, or simply decided to make stones in the future of exactly the shape that is most interesting to him (after all, in the supermarket all products are standard).

Finished model can give you a maximum of several kinds of finished product in production. Forms made by yourself - even dozens, depending on your imagination and the initial materials for creating the layout.

wooden forms

wooden models- not the most good example, but we must also point to it, because the production of stone with their help takes place. How is the production of the model under facing material?

Everything is quite simple here - to create a wooden model, several old boards are selected, preferably with a maximum of defects, as well as even slats. The bottom of the model is made from the boards, the side sides are made from the rails. We take old and broken boards so that the upper, decorative part of the stone has a unique shape, with a peculiar pattern. The sides must be even, as well as additional partitions inside the form, so that we can maintain the same distance between the stone during laying. Although, if the stone is made for a chaotic pattern, you can do everything according to your own requirements, the shape can even be non-standard curve, partitions can draw the most intricate patterns and shapes.

The model is knocked down with nails, it is well strengthened and compacted so that the future solution does not go anywhere from it. In terms of size, the decision is only yours, since we cannot decide for each summer resident what characteristics he needs material.

We simply cannot assert the practicality or high quality of such a model for the production of stone. No, of course, there is experience working with such structures, but not the best, and even more so, today there are more confident technologies that provide a decent result.

Silicone stone molds

Making such a design will take you some time, plus there will be inconvenience on a trip to the supermarket to purchase supplies, as well as some costs. But as a result, you will get a truly exclusive stone that no one else has, if, of course, you can cope with the production process the first time.

Choosing samples for mold making

Perhaps the easiest step in the process, when you need to determine what type and size of material you want to receive subsequently. To select a sample, you can take a natural sample, its fragments, do something yourself, breaking stones or cutting and turning their edges.

We make a mold for casting a model

Here we need production experience wooden boxes and boxes, which is generally very simple. As a basis, you can take a piece old furniture, square or rectangular sheet of laminated chipboard, for example. Next, you need to nail to the sheet of the side of the height of the thickness of the planned production of the model. Everything should be tight enough and reliable, you can even smear all parts with glue, and only then twist them with screws or knock them down with nails.

Laying the stone into shape

We carefully lay out the samples that we found in the country or made with the help of a tool. Be sure to keep a certain distance between them, a few centimeters. When laying the stone on the bottom of the box, we coat the joints with plasticine so that the liquid silicone does not flow under the samples.

When preparing a stone, it should be understood that one side of it should be flat, this is necessary for convenient packing in a box, as well as in order to get quality material for work, one side of which will be able to adjoin the surface being trimmed.

Preparation of silicone for mold production

There is nothing complicated in the preparation of the material - you just need to work according to the instructions, add the hardener and catalyst in the required proportions, mix everything thoroughly using an electric mixer.

After preparing the silicone, let it stand for about half an hour and proceed to the next step.

Filling a Shape

Stones are checked for correct installation in a box, coated with grease or other lubricant, and silicone is poured into a box with stones. During this process silicone should be constantly rammed so that it lays down in an even layer. It will also eliminate the formation of unnecessary voids in the future form. Pour in the silicone until it covers about 5 cm of the tallest stone in the box.

Now the molds with silicone must be placed in a dark and dry place, and let them dry well. In some cases, the product is ready in 36-48 hours, but sometimes you have to wait a week. It all depends on the material and conditions of production and drying.

At the end of the drying period, the side walls of the box are removed, and finished form carefully separated from the sample stones. Now it is completely ready for use for the production of the material.

How to make a mold for artificial stone (video)

Forms for artificial stone will help you with the production of high-quality facing material that can be used for interior and exterior decoration, laying paths, decorating flower beds and other work in the country.

We thank each reader for the time spent, and also invite you to participate in the discussion of this topic.

You can decorate the interior or exterior of the house with the help of not only natural stone, but also its imitation, which is now in increasing demand. Of course, natural stone looks beautiful and dignified on the building, but do not forget that the price for this beauty will be appropriate.

Artificial stone does not lag behind in beauty and quality from natural, at its lower price, however, if you plan to use a large amount of artificial stone, then the price will be quite noticeable, despite the fact that the artificiality of the material.

The cheapest option for artificial stone is to use a polyurethane mold. This method is the best way to save your cash, moreover, he will serve you for a very long time. A mold made from liquid polyurethane is synthetic material, which contains two components. After these two materials are mixed in different proportions, the process of their hardening takes place, and the resulting material is similar in its properties to silicone or rubber.

This article will tell you about the process of making a mold for artificial stone.

First of all, you need to stock up on the following materials: liquid polyurethane with two components, some artificial stone for shaping, a couple of scraps of MDF board, self-tapping screws, a mixer designed for domestic work, a bucket with a capacity of one liter, silicone, scales, a separator, and a spatula.

Making a mold for artificial stone from polyurethane step by step operations

First of all, you need to purchase one pack of artificial stone that you like. In most cases, one package contains no more than one square meter stone.

On the sheet MDF boards it is necessary to place half a square meter of stone. All pieces should fit, with gaps of approximately one centimeter between tiles. There are no rules for the location of the stone, so you can safely experiment. Then each stone should be glued with silicone.

MDF trimmings are useful in order to make boards, the height of which will be slightly higher than the edges of the stones. It will be enough to fix them with self-tapping screws, then it is necessary to seal all the cracks with silicone so that the polyurethane does not leak out during its pouring.

The future form should be set exactly using the level. This will help you get in shape without height differences.

As soon as the silicone has hardened, it is necessary to cover the formwork and the stone itself with a separator. One of the main elements in the separator is PVA or, in other words, polyvinyl alcohol, which, after curing, creates on the coated surface thin layer films. After the separator has crystallized, you should go directly to the pour.

Duramould ET 45A is one of the highest quality and most durable two-component polyurethanes available. It is distributed in two containers, each of which is five liters. One contains a red liquid, the other white and thicker. Scales will be needed in order to measure 500 milliliters from each canister. Then they should be poured into a bucket and mixed with a mixer. The mixed liquid is poured into the prepared formwork. Generally, right technology mixed polyurethane involves the use vacuum chamber, but it is unlikely that most people have one. Don't worry about air bubbles, as the polyurethane creates enough pressure for them to dislodge themselves. Don't forget to mix in correct proportions, otherwise you run the risk of creating a poor-quality form.

Polyurethane should be poured slightly above the edges of the stone. About a day is enough for it to completely solidify. Polyurethane "loves" positive temperatures, so you need to take care of the heat in the room. The ideal temperature is considered to be at least 22 degrees. As such, polyurethane does not have a “recognizable” smell, but still you should not do this at home.

After hardening, the polyurethane will turn into a fairly dense form, which is ideal for creating artificial stone. It remains to disassemble our formwork and trim the sticky places. After removing the formwork, you can tear off the form. If you didn't save on silicone and glued the stone well, it will stay on the table, otherwise it will stay in shape. If this happens, you need to squeeze the stone tiles out of the mold.

The form, freed from tiles, must be left for a while to dry completely. The parts of the mold that have not been in contact with air will feel slightly damp and greasy to the touch. A simple rag can easily cope with this task, then you should again let the form dry. After all the procedures, the mold is completely ready for work on casting artificial stone. Also, do all this procedure with silicone and make silicone molds for artificial.

Having made such a form, you special efforts make an artificial stone with your own hands for the decor of your room. Thus, significantly reducing the cost of home repairs.

Making molds for artificial stone: video

Artificial stone appeared on the market building materials not so long ago, but immediately gained popularity all over the world. This is a convenient facing material that allows you to easily, quickly and inexpensively ennoble the facade of a house or backyard. The cost of finished artificial stone is often indecently high, so many people prefer to do it themselves. For this you can buy special form with the desired texture, but if you want to create something completely original, then you can make it yourself. In today's article, we will talk about just that and tell you how to make a mold for artificial stone.

There are several varieties of molds for the manufacture of artificial stone, differing in material. However, the principle of "work" for all of them is the same - on inner surface there is a special texture (wood, rock layers, veins, leather imitation, etc.), cement or gypsum mixture poured into this form, and when it hardens, the texture of the matrix is imprinted on an artificial stone. In fact, the whole technology is very simple, if you have the right consumables, and most importantly, a stone mold.

Depending on the material, the following forms are distinguished:

wooden;
silicone;
polyurethane;
plastic.

It’s worth mentioning right away that the purchased form and the one made by one’s own hands do not have a significant difference in cost when it comes to a single copy. The main reason that you may need to make a matrix for pouring stone with your own hands is the desire to make original products with a special texture and what is on sale does not satisfy your needs. Making a mold for a stone with your own hands will save mere pennies, but it will give you valuable experience and the opportunity to decorate your home.

For comparison, the cost of a standard mold for a decorative stone with an area of 0.24 m² in a supermarket is at least 1,500 rubles. Having bought one product, you can make only one batch of stones at a time, waiting for the solution to completely solidify. Two forms will cost more, but things will go faster. But if, instead of spending money on ready-made matrices, they use it to purchase materials for casting own forms, you can significantly increase productivity and reduce the time of work.

So what are the benefits independent production molds for artificial stone:

Financial savings.
Fast paced work.
The ability to create unique textures and products with original dimensions.
Useful experience.
You can make money by renting or selling forms you no longer need.

wooden forms

wooden forms for the manufacture of stone are not the most good option However, it would be wrong not to mention them in the context of this topic. The technology in this case is very simple - old boards with the maximum number defects - knots, cracks, bulges, etc. The “worse” the board, the more pronounced the texture and the more beautiful the surface of the stone will turn out.

In creating an artificial stone, it is important to obtain a relief surface and even walls, therefore texture boards are used for the bottom of the matrix, and even straight slats or plywood are used for the sidewalls.

All parts are connected to each other, fixed with nails and the joints are well sealed so that there is not a single gap through which the solution can leak. Then it remains only to prepare the mixture from which you will make stones, and pour it into the matrix.

This way of creating forms has the right to exist - it is very inexpensive and simple, but the quality of the result leaves much to be desired.

Silicone forms

The silicone matrix looks like a plastic plane, the bottom of which has the necessary relief. Often this matrix is divided into several elements and allows you to simultaneously receive several products at a time.

Properties of silicone mold for stone:

It has high elasticity and softness, but at the same time it is very tear-resistant.
Preparing it is quite simple - you just need to mix a few components in the right proportion.
By varying the volume ratio of the components, you can change the properties of the material (it is recommended for beginners in this matter not to deviate from the instructions).
In the process of mold casting, small air bubbles will definitely appear in the silicone mixture. They must be removed to increase the strength of the product. To do this, use a vacuum machine.

Not any silicone is suitable for the manufacture of a matrix. It can be classified according to the degree of viscosity. So, liquid varieties are used to create theatrical makeup, in medicine and jewelry, because it allows you to embody forms with high detail. But thicker silicone is already suitable for pouring coarser and simple forms– for artificial stone, baking, paraffin, etc.

Polyurethane molds

One of the most convenient, and therefore popular varieties of forms for decorative stones. Polyurethane products are very durable, have high elasticity and give a high-quality imprint of the texture on the hardened mixture. In addition, polyurethane itself has an enviable durability. Silicone forms, at least most of purchased products, designed for a certain number of fills - 100, 300, 500. Polyurethane matrices can be used much longer, so making them yourself is a profitable investment.

Molded polyurethane is a synthetic product with a viscous consistency, which, after hardening, acquires the qualities of durable rubber. In fact, it can be called the "big brother" of silicone.

Properties polyurethane molds for stone:

High elasticity.
Stronger than silicone.
Long service life.
Resistance to influence of chemical reagents.
Reproduces texture well consumable to the matrix.
Easy to prepare - you just need to mix the two components according to the instructions.
Forming can be done at home.
There is no need to use a vacuum machine to remove air bubbles. In this case, heating with a building hair dryer is used.

Like silicone, polyurethane can be divided into several types depending on the stiffness. Less viscous is used to create molds decorative elements, medical equipment and various buildings. Medium - forms for stone made of gypsum, resin or concrete. Rigid polyurethane is used to make automotive parts, furniture, technical gaskets and various industrial products.

plastic molds

Another kind of stone molds, however, it is not possible to make one at home. Plastic matrices are rigid, so you need to use them with extreme caution so as not to break the product. Their cost, unlike silicone and polyurethane models, is quite low. Basically, plastic molds are used to create paving slabs.

Interestingly, for the production plastic mold polyurethane is used, only the production is carried out by hot pouring and pressing on special factory equipment.

Making a polyurethane mold

Such a superficial view is quite enough to select the material for the form. Plastic products automatically disappear due to the lack of factory equipment. Wooden models are too rough and unreliable. For home use it is better to give preference to polyurethane matrices, since they can make stones from cement and gypsum mortar, they are easy to manufacture, you don’t need a vacuum machine to work, and the price is pleasantly pleasing.

This video shows in detail the production of a polyurethane stone mold:

The whole process of producing decorative stone comes down to holding the mixture in position until it hardens. The instructions below can be used for both polyurethane and silicone molds. The only difference is that in the case of silicone, it is necessary to remove air bubbles by vacuum, and not by heating.

To work, you will need the following tools and materials:

cast polyurethane two-component Duramould ET 45A (polyurethane + hardener) - 10 l;
silicone for plumbing (waterproof);
samples of artificial stone suitable texture surfaces;
MDF furniture board;
delimiter;
mixer (construction or household);
wood screws;
scales (it is better to take electronic kitchen scales, as they are more accurate);
putty knife;
1 liter plastic bucket

Helpful Hint: Samples for creating the relief matrix can be purchased from hardware store- buy the minimum allowable volume or look at the balances or the battle. You can also look for stones with a suitable texture just on the street. shards natural stone can be placed in nice order or lightly grind the edges if necessary.

How to make stone molds:

Helpful Hint: Polyurethane does not emit toxic fumes and does not smell at all, but it is best to work with it in a well-ventilated area. The temperature in the room should be at least 21C.

Despite the seeming elementary nature of the entire technology, skills and strict adherence to the instructions are required to make an ideal and even shape. Mix polyurethane components in a clear ratio - this determines performance characteristics future product. Before starting mold casting, we advise you to practice “on cats” - to make small molds from one brick, stone or embossed tile.

Forms of stones: photo

If you do not know what shape to give homemade stones, we suggest you look at a selection of photos. You can use literally anything as fill patterns, from natural minerals ending with plants, wood and even stucco.

Artificial stone made from casting molds is suitable for exterior cladding, interior elements, borders, tiles, fences. Making stone for specific purposes ensures that the material created will meet quality requirements and provide a consistent appearance. Polyurethane molds for the production of artificial stone allow you to reproduce almost any structure.

Polyurethane mold for artificial stone

Polyurethane molds are the basis production process creating a stone structure. This is the most expensive part tooling and equipment. High quality matrix allows you to turn the poured solution into a durable product.

There are three main types of molds.

Plastic molds are a cheap type of matrix. The material is extremely difficult to process. Short service life - about 50 casting cycles, which requires monthly renewal.

Flexible forms– silicone compounds and resin elastic materials. The disadvantage is an increase in the number of bubbles scattered over the entire surface, and the difficulty in its coloring due to the fat content of silicones, in contrast to polyurethane resins.

polyurethane molds. Durability up to 40 cycles and high levels shrinkage.

Polyurethane molds are preferred for technological process stone casting. If properly maintained, matrices can last for years and produce thousands of elements.

Tools and materials for preparation

For high quality templates capable of accurate texture reproduction natural materials, use molded polyurethane. This unique material is resistant to wear, corrosion and flexible, and withstands high mechanical loads.

Polyurethane molds are made by cold polymerization, a solution for the formation of two-component polyurethane compounds. Despite the simplicity of the technology, a lot of experience is required to create a reliable model.

To get a polyurethane mold with your own hands, you need:

samples of artificial or natural stone;
two-component polyurethane compound;
sanitary silicone;
plywood, MDF or chipboard;
self-tapping screws;
liter bucket;
putty knife.

To make frames, you need to prepare a smooth section of MDF or chipboard according to the size and pattern of the elements of the side walls. On the surface of the plate, by mounting plumbing silicone, a texture sample is copied. The distance from the sample to the side walls must be at least one centimeter. Further, the assembled formwork is sealed with a silicone frame and poured with a solution.

Polyurethane compound

The main consideration when choosing a mold material is the presence of fillers in the compound: to reduce cost, change strength, weight, or appearance castings to make the die design more workable before or after curing. The "A" part of the compound, made from most two-component polyurethane resins, comes with a certain amount of filler already included.

A high quality line of two part liquid rubbers are commercially available that can be poured, smeared or sprayed during the template making process at room temperature.

A polyurethane compound is two solutions based on different polyurethanes. The mixture of the combined components solidifies at room temperature.

The material is designed specifically for the manufacture of molds for casting artificial stone, because due to plasticity, it can easily repeat any complex pattern with maximum accuracy. Because of liquid state, raw materials can be easily measured, mixed and prepared for casting.

The solution has fast time curing, which allows you to work with the matrix a few hours after production, but the time for full stabilization is about 12 hours.

The presence of filler in the compound will lead to exothermic heat build-up, which slows down the setting reaction and reduces the shrinkage rate. In casting polyurethane, it is recommended that when using a significant amount of filler, the percentage of added catalyst be increased from the usual 1% to 2% (even up to 4% with small volume mixing).

Manufacturing process of polyurethane mold

The creation of artificial stone begins with the manufacture correct pattern. A large number of castings can be made from a single quality matrix. With solid shape you can reproduce almost any kind of texture, and create the same tiles or sections, which is important when installing large planes.

Two types of molding processes can be used: open casting and closed casting. Flexible molds can be produced by pouring. In this case, their lower surface will be flat, but due to the deformation of the side walls caused by the weight of the solution being poured, the matrix must be significantly increased in thickness. This leads to a significant consumption of the compound and the cost of the manufacturing process of the casting structure.

Block mold production is the fastest and the easy way, but requires more molding material.

Production stages

The process consists of several stages:

Designing a model - a prototype of stone or tile that needs to be recreated where all the other sections will be located.
Creating a casting box - a frame with walls around the model, you can use plywood.
The molding compound is mixed according to the manufacturer's instructions.
Place the prototype in the die, pouring the material into the corner of the mold so that the solution flows gently through the prototype, as this will reduce blistering.

After the molding material hardens, the matrix is disassembled, the resulting model is carefully removed from the prototype. Open casting is used mainly for flat objects with slight differences in relief. A simple molding method, especially suitable for beginners.

The specimen is fixed rigidly in a sealed polyurethane mould, with pattern spacing typically greater than 2 cm. Ready mix Applied with a soft brush for precise relief coverage and removal of micro-air bubbles. The mixture is then poured in such a way as to provide a minimum mold thickness of 6 to 10 mm. The main advantages of open pouring are simplicity and the possibility of visual control of the air pocket when using transparent polyurethane grades.

Benefits of Forms

Made polyurethane forms have increased plasticity and strength, and thanks to special fillers - high resistance to abrasion. Such frameworks allow you to create stones from silicone, wax, concrete, gypsum, low metal mortars, epoxy or polyester resins.

Advantages of polyurethane mold products:

Products made from polyurethane molds are characterized by a high degree imitation of natural surfaces.
It is possible to use materials that perfectly reproduce the relief of a natural surface.
Thanks to the inner surface of the mold, you can get a variety of product colors and create effects of spraying, blurring, overlaying shades.
The resulting decorative stone has a well-defined geometry and low weight, which ensures the implementation of the design and easy installation.
Molded elements do not require any additional finishing.

Structures for artificial stone made of molded polyurethane, in comparison with the strength of a plastic mold, are productive for 2 years, and have:

Good operating characteristics.
Light viscosity and fluidity.
Low shrinkage.
No deformation.
High hardness.
Thermal resistance.
Resistance to acids and alkalis.
Aging resistance.

Polyurethane molds allow you to create a huge range of models: decorative wall from brickwork, lined with stone or brick, modern 3d panels, large-format decorative stone panels, ultra-thin and flexible stone wallpapers, elite paving slabs, as well as architectural decor elements.
