How to cut decorative gypsum stone

Wood or metal hacksaw, angle grinder, and crosscut saw. talk about the different tools for cutting gypsum trim.

Plaster finishes imitate very well different kinds of stone or brick. A properly laid, high-quality material is difficult to distinguish from the original. At the same time, its price is much lower, which explains the demand for the decor. It is not difficult to glue the plates, but in the process of installation there is often a problem of fitting the elements. Let’s figure out what to cut a gypsum tile with and how to do it correctly.

Features of the trim

The basis for the manufacture of tiles. gypsum powder. It’s mixed with polymers before kneading. These are plasticizers, which give the plates flexibility, gas pedals curing and tinting mineral pigments. With their help, the decor acquires the desired color. Pour water over the dry mixture, mix it and direct it into molds. Production technology involves vibro-casting or vibro-pressing blanks.

In any case, a coating material with good performance characteristics is obtained. It is lightweight, which greatly simplifies the installation and transportation. To fix the panels can be even on the plasterboard.

The finished canvas is fireproof, “warm” to the touch, the porous surface retains heat and noise quite well. The price of gypsum cladding is not high, for its manufacture cheap raw materials are used. At the same time, it is environmentally friendly and recommended for finishing any purpose of premises. The exception. rooms with high humidity, as the decor hygroscopic and destroyed under the influence of water. For the same reason it is used only for internal works.

Dust accumulates on the embossed surface over time. It is quite difficult to clean it, especially if other contaminants have also appeared. To simplify cleaning, it is recommended to cover the finish with a protective layer of varnish. Despite the small disadvantages, paving is considered a successful imitation of a brick or stone. It is chosen to design a variety of interiors.

Paving tiles

Paving slabs are widely used in the market of construction materials. Paving slabs compared with asphalt has several advantages including environmental. It should be noted that the use of paving tiles in modern construction has many prospects.

Paving slabs in the construction of versatile from an engineering point of view, it is easy to lay, durable and saves the budget. Durability. the allowable load on one tile can exceed the weight of a small truck. Paving slabs will not leave you indifferent, it’s easy to buy, because the final cost will be much lower than similar materials due to longevity of use and the initial cost of 1 square meter. Price is one of the reasons why paving sidewalks in cities is so popular.

Depending on where they are used, paving tiles are produced with different technical characteristics. The abrasion and weather resistance of the region is taken into account, the determining property is its thickness. The basic principle on which choose the type of paving tiles is the place of its operation, the thicker the tile, the more heavy traffic it can withstand.

Facade facing stone

Decorative stone quickly entered the market and won the advanced positions of its excellent qualities, as an external unique appearance, and the relatively low cost, variety, durability and ease of use. The entire ornamental stone range is now available in many different applications. Decorative stone gives iridescence and creates a summery mood.

A selection of exterior applications for Decorative Stone is available in our showroom. This decorative stone looks great in forest green and fall areas. Often used in decorating fences, home and street catwalks, and building foundations. The variety of shades allows you to choose the most suitable decorative stone and give the desired atmosphere.

Interior facing stone

Decorative stone made of gypsum is pliable and easy to work with. It can be sawed, cut or polished. Decorative stone is so robust that it can withstand a wide range of stresses and strains. Gypsum stone. a good heat and sound insulator, due to the microporous structure can regulate the microclimate of the room, absorbing excess moisture from the air and slowly returning it in case of shortage.

The gypsum stone is gaining popularity and occurs more and more often. Artificial stone is now present in nearly every second interior, distinguishing it from others by its originality and unique respectability. Decorating with artificial stone looks luxurious and inspires us wealth, respectability and well-being. Hence we can conclude that the artificial stone is firmly in fashion and is gaining popularity, actively gaining momentum in the design of interiors, making them original and unique, and most importantly bright and different from each other.

3D panels

Three-dimensional walls in interior design is one of the most fashionable trends of today. Modern finishing materials. decorative 3D panels for walls, made of gypsum, help to create them. Depending on the design and color of 3D panels in an apartment, house or office you can create absolutely any mood and atmosphere. the atmosphere of soft comfort, reserved respectability or luxury. Three-dimensional decoration gypsum 3D panels can change the space, giving the interior elegance and modernity.

3D panels have important functional advantages:

Insulate the room and regulate the moisture level

Made of ecologically pure natural material

How and what to cut decorative stone

Decorative stone is often difficult to distinguish from natural stone in appearance. Regarding durability, the resistance of artificial stone to external influences sometimes even exceeds. This is the reason why it is so in demand in finishing work. Many people wonder how and what to cut decorative stone, when you need to change its size or give it the necessary shape.

Special stone-cutting machines are used in the manufacturing industry to cut decorative stone and are equipped with a liquid supply for cooling. The machine cuts the stone, which is immediately cooled. The process is not complicated and, to some extent, even automated. Waterjet and laser cutting is also used. The last mentioned methods can give a decorative stone a very different and even unusual shape.

However, in domestic conditions to solve this problem is much more difficult. Help the following improvised tools: hand circular saw, angle grinder with diamond discs of different diameters, electric tile cutter. All these devices are equipped with diamond segmented and solid discs, which can be of different configurations if necessary. It is also possible to cut the stone by hand with a simple metal saw. It is necessary to install on it a blade for the stone, which has a diamond coating.

Electric tile cutters are equipped with tubs for cooling the stone while working. Such tank with liquid is placed directly under the table, on which the tile cutter is installed. Such devices are divided into two kinds: the first has a fixed cutting disk and in the process of work moves only the work table, on which the stone is fixed; the second kind of drive itself moves over a cutting plane.

In some cases a manual tile cutter will be enough, for example, if the thickness of the stone is not great and the relief is not complicated. The most simple and convenient tool is an ordinary angle grinder with a diamond disc of large diameter. Different blades for different kinds of decorative stone. Sometimes, finishing with a decorative stone ( of any room, requires making small cuts or notches on the plane of the material. For this purpose, you can use an ordinary jigsaw or a diamond string.

Cutting is a simple matter, there are two main ways: the first is suitable for builders with experience, the second for non-professionals. On the back side of the stone, you draw a line for the trimmer, along which you plan to make the cut. Next, a knife marks the place where the seam will be. A deep incision is made all along the seam with an angle grinder. Then it is laid on a horizontal surface and broken down. On the front side there is not quite an even crack.

The other method is recommended for people who do not have much experience in cutting stones. Here, on the face of the stone, we mark the place of the seam. After that, you need to saw the stone by hand with a saw with a special blade. You can also use a hand-held power cutter that has a flexible cord.

Gluing gypsum tile. imitation stone

In this post I will tell you how I glued a gypsum tile “like a stone” in the hallway. Especially tell and show their shortcomings, so that interested readers have not repeated my mistakes. Tile for convenience, I will continue to refer to simply “stone”.

And the stone for the hallway, I chose because it is in my opinion practical in all respects:

Approximately as the wall looked like this before we started the work:

it is the reverse side of the finished wall. But the construction was exactly that. The house is made by the frame technology of the 80s at the factory named after V.V. Dukhovny in Saratov.Frunze, if I am not mistaken.

Hallway before the modification had the appearance of a long and narrow room (2.4m x 4m) filled with all sorts of things. I put a wall (in the photo above. on the right) and separated under the hallway about 1.9m (the rest of the space will be dark: flour, cereals, cans, pots).

The house had been without heating for several years and the surface of the fiberboard had become a little floaty and uneven. I tried to level the walls a little with slats (ventzazah in the wooden structures is also not superfluous). Screwed the OSB boards first, then the drywall. This design has two advantages: greater resistance to deflection (t.е. The wall is less flimsy in the hollows) and is made with a double layer of laminated laminated veneer (i.e. the first layer is made of OSB and the second of GPB).е. the joints of the plates don’t match, this will prevent the tiles from falling off, stressing and cracking).

decorative, stone, gypsum

I have the first layer. OSB, the second. gypsum plasterboard. I already had OSB, the scraps of gypsum plasterboard from another room, I added the missing pieces.

Then a boring routine: we chose the texture of the stone, calculated the volume, bought tiles and tile adhesive. Anticipating the fact that it is better to buy all the boxes of one year of production. Tiles of different year of production can differ very significantly.

The construction store had a booth with examples of the finished wall. And practically all kinds of tiles were glued with a 10 mm joint. My question about the availability of crosses 10mm salesman said no. Well, good, less problems with leveling joints and grouting, I thought (yes, now, as it turned out I was very wrong).

On January 2 I started to glue the first wall. Ceramic tile I have glued before, so the experience of working with a trowel and the level was, but with a stone did not have deal. Here is a sample set of additional tools for stone (flat, toothed trowel and short, long levels. these are the basic tools):

Gypsum boards are easy to cut with a regular hacksaw. You can and without a jig, but it’s more convenient, especially since it’s all left after installing the door. Why do I need a knife? I’ll understand later.

The stone was glued with white mosaic glue (450r/25kg), but the store had special ready-made (200r/4kg). Even if you stain the seam or the tile itself, when drying, this glue becomes invisible from a distance. In fact, it is not so white:

Started on purpose with a small wall, after the end of which I realized that I was doing something wrong.

The tiles in the same pack have different sizes in both length and width.

Tiles have a significant surge at the edges, they must be scraped off.

The tiles may have chipped or missing edges due to insufficient material during shoveling.

So quickly “out of the box” to glue is not possible. It is necessary to take all the tiles out of the box, clean them from the build-up, sort them into even and chipped tiles, stack them by height.

The quality is obvious. Sometimes I had the idea that they were made by drunken homeless people in total darkness. The mortar is poorly mixed and not poured to the edge of the mold. And the other one had a lot of overflow at all, a 3mm thick overlay.

Therefore, all tiles must be aligned and sorted:

The difference in height between the first and the last tile in the box can be up to 5 mm. Only 2 of the 21 boxes had relatively identical tiles. The 2012 boxes were about 7mm narrower than the 2012 tiles and differed in color, 2014 was more gray, 2012 was beige, like melted milk.

In future work with such a box will be very convenient. Firstly, you can roughly know the deviation from the level as you go along the row (or several). Secondly you can immediately calculate how many rows of a box are enough. For example, with the length of my wall

I had enough 2.4 m of one box for 3 rows of height. Accordingly, I applied glue to the wall at once for 3 rows and glued tiles as if stairs, just like a brick wall:

This avoided the strong height differences between neighboring tiles (1 and 3, for example).

Planning the distribution of tiles is important not only on a flat wall, but also when laying corners. Here’s an example of what the corners look like with butt (left) and overlap rows (right):

On the right

Here, for example, is the “convergence” of the rows in the corner above the door:

The floor level is the same, but the walls were glued independently.

The other corner is prettier, the effort paid off:

Subsequently, to line up the penultimate row, I sawed the tiles lengthwise. Because if the height of the last row is less than half, there will be an extra consumption of stone. And if the height is too small (2-3cm), then: either it will be ugly, or when sawing tiles it will break (gypsum is quite fragile).

To install the top row, I used all the broken and unconditioned tiles. By the way, they can be used to pass doorways:

decorative, stone, gypsum

The rows don’t add up here either. Nothing, Zur Aby approves, that’s the main thing. We do not keep cats at home, they are in the garage, but there is no less intrusive helper:

Zur Abyy. big brother (older brother) of his sister.

Plaster tile in its pure form draws and smears a little less than chalk and is easily scratched. To protect the wall from dust, dirt and damage I covered it with a matte varnish. The wall began to shine a little. a wet stone effect. To the touch as if not gypsum and polymer, the picture is not visible, although the eyes see it from this angle (photographed on Samsung Galaxy S2):

Finishing with plaster stone tiles.

Gypsum stone became popular because of the variety of forms, ease of manufacture and processing.

But does it make sense to make your own gypsum stone, for cladding in the house?

Even a cursory glance at the price of polyurethane forms and the price of tiles in stores is enough to understand. There is no reason to fill the molds with gypsum. Despite the fact that the process (with ready-made forms) can be cost-effective.

The profitability of gypsum products with molds.

Maybe such calculations influence the market price of gypsum products. The price remains high. Although I do not consider the idea of making gypsum products on the spot as utopia. So, some brigades are engaged in the production of gypsum tile directly during the repair of apartments.

Making gypsum moldings on site.

How to put a gypsum tile.

The variety of shapes of gypsum stone, to some extent, affects the technology of finishing. Some tiles, according to the artist’s plan, are laid on the wall with seams, others without. Below we will talk about the second type of stone, when it is supposed to be laid side by side, without gaps.

It makes laying easier. But the relief is only apparent. They have their own nuances.

The main points of laying gypsum tiles:

If there are corner elements. facing, it is better, to begin with them. But first, check how much they differ in height from the ordinary elements. A difference in size can be up to 2-3 mm. Due to the surge extending to the back of the product, the divergence can still be significant.

All such details can be identified after tiling an inconspicuous area of up to 50 cm in height. In general, the entire intended plane, it is necessary to cross out on 30. 50 centimeters horizontal segments (on the level). This makes it possible to adhere to these lines and maintain the levelness of the laying. Otherwise it could lead to a skewed appearance.

You can cut the gypsum decorative stone with a hacksaw with fine teeth. and finishing with a grater with sandpaper. This is the only advantage of gypsum stone.

Glue for gypsum tiles.

With the adhesive for gypsum tiles is a complete mess. What just do not offer. from the usual adhesive for ceramic tiles to silicone and various “sticky notes” on an acrylic base. That is probably why many packages have information on how to glue the artificial stone of gypsum.

Adhesive for installing drywall can have different names. It’s because of the different manufacturers. But the characteristics of the mixes are similar. they are all based on gypsum with additives. Can be somewhat different in some respects. But not times. The usual variation in quality.

“Perlfix” is produced by the leader of drywall products Knauf. That’s why its quality is higher.

Variety of mounting adhesive for drywall.

The information on this mixture states that curing occurs within 30 minutes. But the performance is lost earlier. It is necessary to count on 10 minutes. Therefore, you need to work quickly and in small portions of glue. For this reason, it is necessary to wash the tools after each batch.

How to apply the adhesive. If there are areas to be laid, you can apply it to a small plane within 0.5 м /2. In addition, it needs to be applied to the back of the tile. It has to do with the uneven back of the stone. The protrusions reach 5-7 mm and are located on the edges of the tiles. Application of double priming reduces the risk of “airing” of the adhesive and voids from unevenness.

In the case of installation of single elements in the corners and when installing trim, you can apply glue only to the stone. Provided that the wall is even. The glue has no time to “air dry”, and all the irregularities of the back side are compensated by the teeth of the trowel.

Ceramic tile glue is an option for attaching gypsum tiles. But not every. Cerezit has a separate adhesive for attaching to gypsum plaster. Perhaps it will do.

Can CM 11 be used to install gypsum tiles?

But the department of technical support from Zeresit could not recommend any of Henkel’s mixes for attaching gypsum tiles to the stone on the balcony.

Does decorative gypsum stone need to be primed?

If the gypsum stone is very wet, it is probably not necessary to primer the back surface.

But in the recommendations for the use of “Perlfix” states that highly absorbent surface should be primed. And dry gypsum stone absorbs moisture even more.

Perlfix Adhesive Tips

On an absorbent, unprimed surface, this is about what happens with Perlfix:

Is it necessary to fill gaps when installing gypsum stones seamlessly?

Because of the difference in size of the stones, between them there are 2-3 mm cracks. The only recommendation from manufacturers in such cases goes something like this:

“To make masonry look natural, you should take stone from different packages.” This advice does little to help the problem of gaps between stones.

Fill the arisen joints or not, it is a matter of taste. Dozens of foreign videos say. They do not “bother” with such a question:

Spain. Gaps between decorative stones during laying.

The easiest way is to fill with acrylic with a gun. But this option is possible for white tiles with white acrylic.

For colored tiles, the grout used for ceramic tiles is suitable.

It is a time-consuming process. In addition, the grout cannot be completely removed from the stone, despite the preliminary priming of the surface and the subsequent “dancing with tambourine”.

The application of the grout mixture with the help of a tube gun makes this procedure somewhat easier.

Filling gaps after laying decorative stone.

To hide completely the traces of grout is possible only by painting the stone. Manipulation with cleaners can lead to irreversible changes in the surface of the gypsum tile.

Labor costs when working with gypsum tiles under the stone is about three times (and, at the subsequent sealing of seams. slots and higher) than with ceramic tiles.

In the case that the gypsum tile after laying, will have to paint, the problem with the gaps is solved simply. Fill the joints (even thin ones) can be made with gypsum, using a small and stiff brush. Gypsum putty should be as thick as sour cream. After 1-2 minutes, after application, wash everything off with a thick brush and water.

Dispersion adhesive compositions and liquid nails

Intended for laying tiles on a pre-primed wall or drywall. Reliable, durable and easy to use. This explains its higher price in comparison with dry mixes.

Ready to use compositions of LITOKOL brand and some others are in great demand among professionals. (Consumption approx. 1.3 kg for a bond thickness of 1 mm). After opening the container, the product retains its properties for no more than 8 hours:

  • LITOACRIL PLUS. acrylic based paste mixture. It is characterized by flexibility, moisture resistance, does not drip from vertical surfaces, quick setting and drying;
  • LITOFLOOR K66. adhesive, used for both interior and exterior masonry. Characterized by resistance to low temperatures, high humidity. Ensures the strength of laying even on surfaces with large irregularities;
  • Casco EXTREMFIX in emulsion form. a universal one-component mounting adhesive of a “liquid nails” type. Cures after 2 hours. Convenient for work in hard-to-reach places;
  • Casco FIX-IN is notable for its versatility and durability. Cures when exposed to moisture. Its properties are not affected by temperature fluctuations. Does not require a preliminary primer. Curing time. 2 hours;
  • The moment of installation universal (type “liquid nails”). rubber. Compensates well for minor surface irregularities.

The physical properties of Decorative Stone

In design of interiors four kinds of an artificial stone are applied:

Decorative stone on cement and plaster bases have uncomplicated manufacturing process. Not difficult to arrange on a construction site or in a small makeshift workshop. It boils down to mixing the prepared ingredients, mixing with water and pouring the mixture into molds, followed by drying. By adding appropriate coloring agents, the desired shades of material are obtained. Decorative stone made of cement is moisture resistant, durable and not afraid of moisture.

Continuation of the above advantages is a relative disadvantage. the specific weight, close to the corresponding parameter of natural finishing materials. It is used for external works: finishing walls of the house with a stone, paving paths, in small architectural forms and sculptures. Decorative stone from gypsum has less weight compared to cement, it is easier to install on the walls of the house, but does not have high strength and moisture resistance. It is used indoors.

Porcelain stoneware and acrylic stone. materials, production of which is possible only in a large factory. The implementation of appropriate technological processes requires complex expensive equipment, qualified personnel, a large stock of raw materials and, consequently, a well-established system for marketing the finished product. For the consumer here is a positive point in a relatively guaranteed quality of products. Large-scale manufacturing must strictly monitor compliance with its products GOSTs and specifications.

Porcelain stoneware, although it does not contain a grain of natural granite, has very similar properties to it. Produced from homogenized, i.e. е. homogeneous mixture, soft clay, chamotte (kaolin), sand, feldspar, pegmatite and water. the material is shaped and takes the required shape by means of semi-dry pressing followed by baking. Firing temperature 1200-1300°C. Used mainly in places where it would be appropriate to use natural stone.
