Selecting the appropriate materials is essential when remodeling bathrooms and toilets. The kind of plaster that is applied to the walls and ceilings in these areas is crucial. Because moisture-resistant gypsum plaster can tolerate high humidity and direct water exposure, it has gained popularity as a material for these damp areas.
In moist environments, traditional plaster can quickly deteriorate and cause structural damage, mold, and mildew. However, moisture-resistant gypsum plaster is made to withstand the absorption of water, guaranteeing that the walls of your bathroom and toilet will remain intact for an extended period of time. This kind of plaster is perfect for painting over or tiling because it offers a smooth and long-lasting finish.
The simplicity of application of moisture-resistant gypsum plaster is another advantage. It can be installed simply and effectively because it can be applied in the same manner as regular plaster. It also has outstanding adhesion qualities, which guarantee that it will remain securely in place even in humid and steamy environments.
You can improve the longevity of your bathroom and toilet while also fostering a healthier atmosphere by selecting moisture-resistant gypsum plaster. This plaster improves indoor air quality by inhibiting the growth of mold and mildew. Moisture-resistant gypsum plaster is a wise and useful choice, whether you’re remodeling your bathroom entirely or just making small updates.

Disadvantages and advantages of gypsum-based mixtures
The following benefits of cement plaster make it popular among builders:
.. The process of using gypsum plaster to level the walls will take no more than three days. Rarely, the procedure can take up to seven days longer than expected (for instance, if the composition is spread out over multiple layers).
Gypsum mixture plastering is significantly quicker than cement analogous plastering, and consumable costs are roughly doubled.
This solution has conditional drawbacks that are not accompanied by
- The possibility of using only interior work, since.. the mixture is afraid of high humidity and temperature fluctuations.
- The cost of the composition is 1.5-2 times higher than that of a cement mixture.
When looking for plaster, the aforementioned drawbacks are not, however, the only ones to consider because there are many more benefits to consider.
For walls in bathrooms and toilets, moisture-resistant gypsum plaster is a useful and cost-effective option that provides greater resistance to damp conditions than ordinary plaster. It guarantees a smooth, long-lasting finish that can tolerate the high humidity levels typical of these spaces in addition to inhibiting the growth of mold and mildew. Plaster that is easy to apply and maintain is a great option for modern home improvement projects because it improves the longevity and aesthetics of walls in bathrooms and toilets.
Is it possible or not to use gypsum plaster for bathroom walls?
Gypsum plaster is safe to use in restrooms and bathrooms due to its high level of adhesion. Usually, the solution is applied to the wall and leveled with the aid of basic tools.
The only issue with plaster made of gypsum is that it loses strength when it gets wet. Because of its porous structure, the material absorbs moisture quickly and can be destroyed if it comes into direct contact with condensate.
In addition, any flaws will be eliminated if the surface is adequately shielded from moisture penetration. To accomplish this, you must use a waterproofing layer to create an insulating film on the wall, at least in damp areas.
Additionally, you can use epoxy grout that has waterproof properties to rub the seams. A unique varnish is then required to complete the coating.
Recommendations of manufacturers
Gypsum plaster suppliers are mindful of the material’s susceptibility to moisture infiltration. As a result, they incorporate unique alterations into the bulk component composition to enhance the coating’s water resistance.
It’s possible that the putty box contains false information regarding its composition and qualities. In light of this, it is preferable to examine the parameters with experts or on official websites.
The Aqualit mixture with higher moisture resistance is made by the Volma company, which is based in Volgograd.
Regulatory documentation
SP 71.13330.2017 is the main regulatory act that controls finishing work done indoors. The requirement that the base be stronger than the finishing coating is stated in clause 7.1.7.
It is not necessary to meet this requirement for plaster that will be tiled.
- The thickness of the tiles should be minimal, and the sizes should vary within 200×400 mm.
- The plaster layer should be 2 times thicker than the tile, taking into account the thickness of the adhesive mixture.
- The composition is distributed over the primed surface to improve adhesion.
How to prepare a gypsum surface for laying tiles in the bathroom
The following preparatory steps should be taken in consideration of the SP regulations prior to installing gypsum tiles in the bathroom:
- The surface to be treated is thoroughly waterproofed (at least in areas where there is a lot of condensation).
- Tile adhesive is poured in a thin layer.
- The tiles used should have a minimum weight and small or medium dimensions.
- Overlap joints must be carefully insulated.
Applying a primer and a coating waterproofing composition on a latex, acrylic, cement, or polyurethane base are required steps. Two layers of waterproofing are applied, one vertically and one horizontally.
Stages of work with walls in the bathroom
Using a leveling gypsum mixture, plastering the bathroom is done in phases:
- Preparing surfaces for applying the layer.
- Securing beacons.
- Preparing the dough.
- Distributing the plaster mixture.
- Grouting.
- Drying.
A ladle, trowel, spatula, building level, hammer drill, container for diluting the mixture, and personal protective equipment are required for this task.
Surface cleaning
Before plastering the walls with gypsum, there are a few things you should do in preparation:
- Get rid of traces of old coatings and dismantle plastic, wooden or metal elements that protrude above the surface. If it is impossible to remove metal structures, they must be treated with anti-corrosion impregnation.
- Close depressions and deep cracks and level out all defects.
- Treat the wall with a primer mixture, which is selected taking into account the type of surface and the humidity and temperature conditions in the building.
Preparing the area
Over oil paint or whitewash, leveling plaster cannot be applied. Furthermore, the outdated and deteriorating coating is unsuitable for further processing. Thus, by cleaning all the way down to the brick or concrete base, all remnants of previous layers are eliminated.
Brickwork exhibits superior plaster fixation, particularly when the joints are one centimeter deeper and the surface is brushed with a wire brush.
Grease, bitumen, mold, and rust traces are just a few examples of the stains that need to be chipped off or removed with specialized compounds in order to reveal clean material. Dowels, nails, staples, and other metal objects must also be removed.
Utility openings are completely cleared of any remaining mortar and given a thorough cleaning and dusting. Broken bricks combined with cement mortar are used to fill in large spaces. Masking tape can be used to close any gaps left for communications. Lastly, a primer is applied to the base (sometimes twice) and allowed to completely dry.
The durability and overall quality of the finish are influenced by how well the treated area is prepared for leveling. Thus, consider the nuances mentioned above if you are unsure if you really need to perform such procedures.
