The production of decorative stones has two directions – the production of facade stone and the production of interior stone. Despite the fact that in either case it is a decorative artificial stone, from an aesthetic point of view, different evaluation criteria are applied to them. The interior stone should have the most elaborate texture, repeating natural material, interesting color solutions with used professional painting technique.

If we analyze the market of manufacturers of interior stone, we can conclude that in this industry demand exceeds supply and this demand will be constant, as it is currently very fashionable to use decorative stone in the interior of apartments and private houses, and natural stone is very poor in choosing textures and color solutions and will never be able to satisfy the diversity of tastes and desires of potential buyers. In the market there are a small number of companies offering elastic forms for stone. This market situation is due to the fact that there is very little information about the specifics of the production of interior stones, painting techniques, composition features and the absence of domestic producers of elastic forms.

Self-respecting companies select a special raw material composition adapted to the place of use of the stone – indoors next to people. From the point of view of production, the form in which it is made is fundamental for the appearance of the stone. Traditionally, for the manufacture of facade stones are used plastic forms, as a more affordable and affordable material. However, plastic is not able to convey all the nuances, texture and feature of natural stones. Therefore, for the production of interior stone, you must use elastic forms. Elastic forms are made from various materials – rubber, polyurethane, silicone. Predominantly polyurethane and silicone are used imported, in order to achieve a good quality of removal and relative durability of the form. At the same time, these are very expensive forms that require relevant experience and knowledge in work. Otherwise, it will be money thrown to the wind.

Silicone is a fragile material, elastic forms of silicone are often torn, deformed, which makes it impossible for further operation. Polyurethane is a more durable material, but it has a greater adhesion to concrete in case of overdrying of the stone at the moment of its set of stripping strength.

The most versatile, durable and durable material for the production of elastic forms is rubber. Its performance characteristics are not in doubt, since this material is used in many industries as the most high-quality and durable (the material used in the manufacture of tires is able to withstand significant operating loads).
