Decorating the walls with stone has a long history, and is still very popular, despite the abundance Tips for making stone from gypsum at homemore modern ways of finishing. But, as you know, natural stone is not cheap, so to reduce costs you can resort to its independent production. The most acceptable option for this is an artificial stone made of gypsum, because for the implementation of the technological process does not need large production areas and sophisticated equipment. To do this, you need a desktop, a rack with shelves, and also forms for pouring. It is best to use silicone for their manufacture, although metal, plastic and wood are also often used. But it is silicone that allows you to give the fabricated samples a given texture with all sorts of small features.

The form is made on the model of this stone, found, or purchased in the store. As a formwork any strong box of a slightly larger size than the stone itself is used. The stone and the inside of the box are smeared with silicones, and the stone is laid on the bottom. After that, the silicone is poured in such a way that the stone is completely covered and the surface is leveled with a spatula. Next comes the drying form for a few weeks. It makes sense to make several similar forms, for the speed of the subsequent manufacturing process. After the mold has completely dried, it is gently cracked, removing the sample stone. There are ready-made forms on sale, so you can use this option.

The process of making artificial stone from plaster is carried out in the following sequence:

1. Mixing. Plaster is poured into a container with clean water and stirred. The proportions in this case are observed independently, the main condition is that the mixture is reminiscent of dough of medium thickness (the liquid solution solidifies longer and is less strong).To increase the strength, you can add sand - up to 10%. The volume of the solution should not exceed the volume of the forms: the solution quickly sets, and simply disappears. If the task is to obtain a stone of a certain color, a dye is also added to the prepared mixture.

2. Forms need to be lubricated with a special solution of wax and turpentine: this will ensure easy extraction of finished products.To prepare the solution, the principle of a water bath is applied, which allows the wax to be well dissolved. The lubricant is applied a small thickness on the inside of the form. To prevent the formation of shells on the fabricated samples, the molds are also lubricated with liquid gypsum.

3. The next step is to pour the solution into the molds, with the surfaces leveling with a spatula.Each form is covered with a piece of corrugated glass and is carried out through vibration, for uniform shrinkage of the solution. This procedure usually takes a couple of minutes. The hardening time of gypsum leaves 20-30 minutes, after which the formed samples must be removed from the molds for subsequent drying in the open air. It is not recommended to use artificial drying as it will significantly reduce the operational capabilities of the obtained stone.

4.Painting can be carried out after drying the gypsum stone.To do this, its surface is cleaned of dust and dirt, and hides the dye solution. The number of layers is determined independently - the main thing is to get the shade of the required intensity.
