The use of gypsum

Although gypsum stone is manufactured in factories, it can also be made by hand from dry powder if preferred. All you have to do is combine the product and water, transfer the mixture into the mold, and allow it to freeze. There will be a gorgeous figure, tile, or other item available. Sand, modifiers, and different paints and pigments are added to the mixture to give it a particular color and to fortify the fortress.

Gypsum stone is used to face walls and doors because it frequently resembles artificial brick or tiles. It complements wood, tiles, plaster, wallpaper, and murals well. GIPS is appropriate for both complete and fragmented finishes; it highlights column foundations and is frequently paired with fireplaces. Gypsum stucco molding, as well as wall and ceiling moldings, are available at all construction supply stores.

Figures for gardens, sculptures, and figurines are made with gypsum powder. Building mixtures are made for internal and external repairs based on this foundation. Dry gypsum is a great way to join plasters, putty, adhesive, and other building and finishing supplies. Why did professionals select it? The content offers a lot of benefits.

  • attractive appearance;
  • small weight combined with strength;
  • the ability to make a unique decor;
  • the creation of a layer of sound, thermal insulation;
  • environmental friendliness, harmlessness for humans;
  • lack of risk of mold, fungus;
  • vapor permeability;
  • ease of processing and imposition on different surfaces;
  • Easy change in form using accessible tools.

Gypsum varnish – types and advantages

Painting gypsum is a popular choice because it is typically realized in its original (gray-white) form. Painting will guarantee that the material that is glued to unique compositions loses some of its hydrophobicity. The application of a unique layer of protective varnish may be part of art design.

To allow the glue to fully dry, lacing is typically done five to ten days after tile laying is complete. Decorative gypsum lacques can vary in composition and characteristics. Numerous paints and varnishes are safe, reasonably priced, let the base breathe, and don’t clog it. In addition to strengthening and improving the coating’s external appearance, varnishing slows down the rate of deterioration.

Shellac material

The most common uses for this kind of varnish are in finishing and decoupage projects. Its alcohol base makes it a highly effective covering material for gypsum. Shellac works well on metallic colors, but it can be applied to any kind of color. In addition to providing thin polishing, the tool is used in furniture processing.

Shellac alone has the ability to impart color to gypsum stone, similar to how transparent and colored materials do. Certain tint varnishes create the appearance of faux tile aging. Usually, masters like to impregnate a gypsum with a 1:1 ratio of shellac to rosin, which completely excludes spots from the surface. The tiles take on the appearance of marble.

Acrylic lacquer

This kind of varnish contains acrylic as the primary polymer along with modifiers, resins, and a water base. It works well both inside and outside and is not overly thick—rather, it’s more akin to cream. The finish coating is typically applied with acrylic varnish because it forms a solid film that has a water-repellent quality. The polymers found in varnish will shield the tile from UV radiation and burnout.

Matte, glossy, and semi-duma acrylic varnishes are available in stores. Gloss imparts gloss to gypsum, but it also greatly reflects light, so when painting, it must be considered. Conversely, matte varnishes add solidity and create an opulent, expensive look. Every acrylic composition is safe for the body, quick to dry, and simple to apply. LCM will turn transparent and fully preserve the stone’s exterior beauty after drying.

Oil varnish

Applying oil varnish to a gypsum base is also appropriate. The material has an oily texture and contains plant additives and synthetic resins. Once applied, it creates a film that shields the base from harm and the effects of external factors. Oil varnishes can also have a glossy or matte finish. They use specialized solvents for their breeding. The stores sell tint materials that add a gorgeous color to tiles. The oil varnish darkens after drying; the designer should account for this.

Yacht varnish

This type of varnish is also based on oil, but its strength is higher. Since getting rid of drones is a challenge, it is applied in very thin layers. This product takes a minimum of one day to dry, and the drying process takes longer in a room with a low temperature.

Painting of decorative stone

Covering gypsum stone varnish presents a fantastic chance to enhance the material’s functional and aesthetic qualities. LKM can be selected based on personal preferences, including color, linen power, and other attributes.

Coloring rules

The following suggestions need to be adhered to in order to get the best outcome:

  1. All gypsum products, individual elements before starting work need to dry well. The glue should be dried, like previous layers of coating (for example, paint or enamel).
  2. Before work with figurines, figures, other products, they must be kept at room temperature for at least 24 hours. Otherwise, the varnish can quickly lose operational qualities.
  3. Rude parts must first be sanded. It is better to do this even before gluing on the walls, because then the process will cause complexity.
  4. If additional use of impregnation is planned, it is important to carefully read the instructions for a specific material. Some impregnations are applied to varnishes, others after them, others do not combine with varnishing at all.

It is important to keep in mind that glossy varnishes add a festive vibe but lessen the impression of naturalness. Matte LKM is a better option if the room is designed in a naturalistic style.


The coloring technique will determine which tools are used. You can use an airbrush, roller, brush, or sponge to apply varnish. Hard-to-reach areas are typically tinted using small brushes. If the product has to be ground, you’ll need sandpaper or a grinding machine in addition to a vacuum to clean up any dust and debris. Additionally, you must cook:

  • rags;
  • degreasing solution;
  • impregnation (if required).

Regular natural-material painting brushes and villous rollers are not appropriate for varnishing gypsum stone. Simultaneously, there will be streams on the surface and a high varnish consumption. You must use caution when using a brush: even the most skilled artist cannot prevent flows and divorces. However, if you need to paint the "torn" portions of the cladding, don’t do so without a brush.

Spraying has a lot of advantages over other varnish application techniques. The base will be uniformly covered by Airbrus, making the surface plain. Varnish effects can be achieved by varying the distance from the nozzle. Furthermore, the airbrush is the only tool that can create a seamless transition between areas that are lighter and darker.

Expensive equipment is not required for varnishing and painting. Even the most affordable airbrush, a spray gun, works well. The compressor’s quality is the only thing that matters because it will ultimately determine how the staining turns out.

Preparation of stone

The preparatory activities are easy. Dust and pollution must be removed from gypsum parts, but moisture cannot be added to the material. It grinds if needed, and then dust turns its face away once more. Next, the chosen impregnation method is used (e.g., to boost moisture resistance or with antiseptic properties). After impregnation, gypsum tiles need to be given enough time to dry thoroughly.


You color in the selected manner. To ensure that there are no dry spots, each component is stained differently. If not, the tiles’ edges will be white. Frequently, they create paintings using two colors: lighter and darker, and the work is then completed in accordance with a pre-planned scheme. Strongly relief tiles are best treated with a spray gun; regular brushes are ineffective for this type of work. An alternative staining method involves immersing every component in a coloring solution. However, in this scenario, consumption might rise, and painting large products will be difficult.

Staining methods and their subtleties

With its range of effects, gypsum painting might not be your typical kind of painting. Some provide an aged appearance, while others create a unique tide.

Under marble

The store-bought items hold up at room temperature for 48 hours. When making gypsum tiles by hand, it is given time to completely dry. After that, carefully impregnate the gypsum surface twice with the heated olifa. You shouldn’t overlook even the smallest details. Olifa can be dried before applying matte varnish, which is colorless. "Under the old man," the surface will take on the appearance of marble.

Under terracotta

As a covering composition, shellac is utilized (clean or mixed with rosin). Technical alcohol is used to dilute LKM slightly. The surface will have a brownish color and resemble terracotta in a few days.

Under bronze

After thoroughly soaking in olifa, gypsum is dried for up to ten hours. After that, prepare the bronze powder, dilute it with any varnish, and apply it to the products in two layers. The substance is once more dried. Then, come up with this fix:

  • 10 g of silver nitrogen;
  • 300 g of water;
  • 100 g of vinegar essence.

Such a solution is applied directly onto the bronze layer of the gypsum parts. This causes the powder to become oxidized. Next, a velvet rag needs to be used to wipe the base. Wax is another option for surface treatment.


Although a spray gun is typically used to apply the stain, products will look even better after being submerged in the tool for 10 seconds. The stain is first slightly heated. Gypsum parts are dry after application.

Gypsum and artificial stone surfaces can be made to look better and last longer by using lacquers, which add a layer of protection. Users can get the best results and guarantee the longevity of their painted surfaces by adhering to the manufacturer’s instructions.

Before applying the lacquer, the surface must be properly prepared. This involves giving the surface a thorough cleaning to get rid of any dust, grime, or debris that can compromise the lacquer’s adhesion. Furthermore, a smooth and even application of the lacquer is ensured by eliminating any imperfections and letting the surface dry fully.

It’s important to adhere to the lacquer’s manufacturer’s instructions regarding application technique and drying times. To achieve an even coat and a polished finish, use the brushes or sprayers that are recommended. Enough drying time should be given between coats and prior to handling the surface to guarantee that the lacquer cures correctly and offers the best possible protection.

For the user’s safety and to speed up the drying process, adequate ventilation is crucial during the application and drying phases. Sufficient ventilation promotes even and seamless lacquer drying by preventing the accumulation of fumes. Additionally, as this can impact the drying time and outcome, it is imperative to avoid applying the lacquer in extremely hot or cold temperatures.

In conclusion, users may successfully apply lacquers to gypsum and artificial stone surfaces by adhering to the manufacturer’s instructions and taking the required safety measures. For painted surfaces to look professional and last a long time, proper surface preparation, application methods, and drying periods are essential. It is possible for users to have beautifully lacquered surfaces that are both aesthetically pleasing and durable with close attention to detail and adherence to best practices.
