forms Materials for the manufacture of artificial stone

Forms for the production of artificial stone in recent years become especially popular.

Buy ready-made material is expensive, and decorate plot, house unusual design solution everyone dreams.

Forms for artificial stones are rectangular, square, diamond-shaped, angular, they can be bought ready-made and can be made with your own hands.

material used for the manufacture of a different - it's a tree, silicone, polyurethane.This is what we describe in our article today.


  • wooden form
  • silicone or polyurethane molds
  • artificial stone - from what to do?

wooden form

wooden form - not the best option for the manufacture of artificial stone, but at the same time it is also used in the construction work.

To do it with your hands, prepare the following material.


It is a few planks, preferably old, with a unique design, and it will form the bottom of the mold, and hence the appearance of artificial stone pattern.And smooth rack - are to be made and the board walls.

Depending upon the intended design, partitions can form identical patterns, or they are arranged randomly in a non-standard curves.

form going with nails, carefully sealed and strengthened in order to avoid leakage of the cement slurry.

As you know, the size of the form is determined individually in each case.

silicone or polyurethane molds

silicone or polyurethane molds more complex to manufacture than wood, especially if you plan to make their own hands, but they allow you to make not only a rich variety of patterns, but also the manufacture of artificial stone technology is moresimple, they are practical and durable.

truth here it is worth noting that the silicone and polyurethane as the material is quite similar, but the silicone material is considered to be more durable, again, less expensive polyurethane.

Set for the manufacture of stone

The first thing you need to start the production of shapes with their hands - it is to choose the future patterns of artificial stone.

As the initial bases suitable natural material - natural stone fragments, they can get their own, breaking the rock and grind the edges of the fragments.

Since silicone and polyurethane casting equipment made way, even though your own hands, you need to make a baseline.

Take any wooden material: plywood, chipboard sheets, remnants of old furniture and stuff.It is desirable that the wooden blanks were smooth, make it easier to remove from the base of the finished shape.

bring down a wooden box, depth which is equal to the depth of the future form.

All wooden parts are connected to each other with screws, for the best effect, in order to avoid leaks, you can glue.

Harvesting must be flat, its size is determined by your wishes for the future form.

Puts prepared stone blank box on the bottom-up pattern caused joints plastered clay to the silicone does not drip under them.

better if wrong side of natural stone is smooth, it will provide a snug fit to the stone base.

silicone or polyurethane are preparing exactly with the accompanying instructions to these materials, always keeping the proportions of hardener and a catalyst.

better if you stir the mixture using a drill with a paddle "mixer".Ready solution should be let stand 30 minutes.


While the solution advocated, check the correct positioning of the stones at the base (this depends on the pattern of future artificial stone), obmazhte their grease.

Ready silicone or polyurethane solution was poured into a baseline, periodically tamping it, to avoid the formation of voids in the form and to ensure the uniformity of the silicone layer.

mixture should cover the highest natural stone in the preform for at least 5 cm. Otherwise, the bottom of a future equipment will be thin, and therefore, operation of the process is not durable.After

as polyurethane or silicone mold, or rather their baselines are filled, they must be placed in a dark place and leave solidify.

Depending on the composition of the solution drying process takes 36-48 hours, but it happens, and you have to wait for a longer time.

But patience - this is one of the components of success for the production of forms by hand.

As soon as silicone or polyurethane is dry, side bumpers at the original foundations are cleaned and ready form of neatly separated from the stones.

can start making natural stone, silicone or polyurethane molds (depends on what material you will use), made with his own hands, ready.

artificial stone - from what to do?

Artificial stone can be made of gypsum plaster or of a mixture of sand, water and cement.

product of the cement mixture made of several layers.

mixed for the first layer the proportion of 1: 3 cement and sand, are added if necessary and desired color dye diluted with water until creamy.

resulting mixture fill the form in half.To cement the mass of compacted, it is shaken or tapped.To the stone was a durable, reinforced it.Video


used as reinforcement in a metal mesh, which is placed in the form on the first layer.On top of the grid fill in the second layer of the cement weight.

cement on top, you can make small grooves that facilitate adhesion to the surface of the product to which it will be laid during installation.

mixture was allowed to stand for 12 hours, then the resulting stone is removed from the mold and dried for two weeks, and poured into a mold a new portion of the cement mixture.

silicone or polyurethane molds should be washed after each generated product.

artificial stone manufacturing technology of plaster, in principle, no different from the process of formation of the cement.

However, we must remember that, in contrast to cement, gypsum material hardens quickly.

Therefore, the amount of the mixture is kneaded a small (extra frozen plaster is not suitable for the manufacture of stones), and to prolong the setting time, the gypsum mixture can be added citric acid.


form before pouring grease with vegetable oil that facilitates the process of taking out the finished stone of the mold.

And as gypsum mixture dries very quickly, while the formation of the finished product is no longer calculated in hours and minutes.

artificial stone made of plaster can be manufactured in various colors.

dyes are added directly to the mix when mixing, and covered with a special paint finished gypsum products.

For the latter to cover the stone cleaned with a clean cloth from dust, sand, and only then applied the paint.Number of paint layers depends on the desired color shade.

Therefore, many prefer not to add the dye in a mixture of plaster and paint cover the artificial stones, giving them not only the desired shade, but also accounting for interior decoration drawing of finished products.


Artificial stone, produced in molds made with their own hands, will always be different.The material for its manufacture can be concrete, plaster, cement.

Applications of artificial stone are different: wall cladding, fences, putting some garden paths, mosaic decoration.
