Gypsum stone has gained popularity due to the variety of forms, the simplicity of its manufacture and processing.
But is there any sense in producing gypsum stone yourself for cladding in a house?
Making gypsum stone.
The price of molds and stone
Profitability of gypsum products in the presence of forms.
Maybe such calculations influence the market value of gypsum products. Their price remains high. Although the very idea of making gypsum products in place I do not consider utopia. So, some teams are engaged in the manufacture of gypsum fillets directly during the repair of apartments.

How to lay gypsum tile.
The variety of forms of gypsum stone, to some extent, affects the technology of decoration. Some tiles, according to the artist, are laid on the wall with seams, others without. Below we will talk about the second type of stone, when they suggest laying the stone close to each other, without gaps.
This makes installation easier. But relief is only visible. There are nuances.
Highlights of laying gypsum tiles:
In the presence of corner elements. facing, it is better to start with them. But first check how they differ in height from ordinary elements. The difference in size can reach 2-3 mm. Due to the influx, expanding to the back of the product, the discrepancy can be even significant.
All such details can be revealed after facing an inconspicuous area with a height of up to 50 cm. In general, the entire estimated plane needs to be drawn into 30. 50 centimeter horizontal segments (by level). This makes it possible to become attached to these fishing lines and observe the horizontal styling. Otherwise, cosine may appear.
You can cut a gypsum decorative stone with a hacksaw with small teeth, and finish with a grater with sandpaper. This is the only merit of gypsum.
Glue for gypsum tile.
What glue is needed for gypsum tile.
Glue for gypsum tiles is a complete mess. What they don’t offer. from ordinary glue for ceramic tiles to silicone and various “stickies” based on acrylic. Therefore, probably, information appeared on many packages about how to glue artificial stone made of gypsum.
Information on the packaging.
Glue for the installation of drywall can have various names. This is due to different manufacturers. But the characteristics of the mixture are similar. they are all based on gypsum with additives. May vary slightly in some indicators, but not at times. The usual variation in quality.
Perlfix is manufactured by Knauf, the leader in drywall products. Therefore, his quality is higher.
A variety of mounting adhesive for drywall.
The information on this mixture indicates that solidification occurs within 30 minutes. But working qualities are lost earlier. You need to count on 10 minutes. Therefore, you need to work quickly and in small portions of glue. For this reason, you have to wash the tool after each batch.
How to apply glue. If you have to lay areas, then you can apply on a small plane within 0.5 m / 2. In addition, it is necessary to apply on the back side of the tile. This is due to the uneven back surface of the stone. The protrusions reach 5-7 mm and are located at the edges of the tiles. Double spreading reduces the risk of glue sticking and voids due to bumps.

In the case of mounting single elements at the corners and when laying the trim, you can apply glue only on the stone. Provided that the wall is flat. The glue does not have time to “wind”, and all the irregularities of the back side compensate for the trowel teeth.
Glue for ceramic tiles, as an option, is possible for gluing gypsum tiles. But not everyone. “Ceresit” has a separate adhesive for attaching to gypsum plaster. Perhaps he will do.
Can I use CM 11 for laying gypsum tiles?
But the department of technical support Ceresit could not recommend that either of Henkel mixes for fastening gypsum tiles under a stone on BAL-KOne.

Do decorative gypsum stones need to be primed?
With a high humidity of gypsum stone, it is possible to prime the back surface and it is not necessary.
But the recommendations for using Perlfix indicate that a highly absorbent surface must be primed. And dry gypsum stone absorbs moisture even like that.
Recommendations for working with Perlfix glue
On an absorbent, unprimed surface, with Perlfix something like this happens:
Do I need to fill the gaps for seamless laying of gypsum stones?
Due to the difference in the size of the stones, between them there are gaps of 2-3 mm. The only recommendation from manufacturers in such cases is something like this:
“To make the masonry look natural, you need to take the stone from different packages.” This tip does little to help the gap between the stones.
The cracks between the stones.
To fill the arisen seams or not, it is a matter of taste. Dozens of foreign videos say that they do not “bother” with this question:
Spain. Cracks between decorative stones when laying.
This affects the CIS more:
How and how to fill the seams?
The easiest way is to fill with acrylic using a gun. But this option is possible for white tiles with white acrylic.
For colored tiles, grout used for ceramic tiles is suitable.
This is a time consuming process. In addition, it is not possible to completely wash the grout from the stone, despite the preliminary priming of the surface and the subsequent “dancing with a tambourine”.
This procedure is somewhat facilitated by applying a grout with a spray gun.
Filling cracks after laying decorative stone.
You can completely hide grouting marks only by painting the stone. Manipulations with cleaners can lead to irreversible changes in the surface of the gypsum tile.
Labor costs when working with gypsum tiles under a stone are about three times (and, with subsequent repair of joints. cracks and higher) than with ceramic tiles.
How does primed and non-primed gypsum tile hold in a short video:
If the gypsum tile after laying is to be painted, the problem with crevices is solved simply. Fill the seams (even thin ones) with satengips using a small and stiff brush. Gypsum putty should be similar in thickness to sour cream. After 1-2 minutes, after application, wash everything with a thick brush with water.

They face the same problem when laying 3D panels. The name of the 3D panel is an advertising trick. In fact, this is the same gypsum tile, but large. And her problems are the same as those of gypsum tile. a spread in size, uneven shapes and crevices that arise in this case:
Thank you, I will consider all the practical advice. I will throw them into my notes. I put gypsum tiles under my stone — a chimney — wish me luck.

This is not a chimney, but a ventilation duct. So the architect conceived.
Thanks to the author!
He fenced the fireplace (false wall) from drywall to the middle of the fireplace natural stone (sausage of different lengths)
put ceresite on the glue. for 10 years everything has been holding like a dragon around the firebox too / despite the high temperature!
