The bathroom is a room with a huge coefficient of humidity. This fact is undeniable, therefore, taking into account the finishing should take into account many factors. Most craftsmen, specialists and various experts who have even little knowledge agree in one opinion - tiles will be the ideal application option.

However, today we are interested in stucco under tiles in the bathroom, including on concrete walls, because, like tiles, it is able to cope with temperature extremes, withstand enormous dampness and resist the aggressive effects of steam.

What kind of plaster to use in the bathroom, how to properly plan the workflow, what moments deserve the most focus? We will answer.

sanitizing solutions.

Bathroom tile plaster must have sanitizing characteristics. Modernity has a huge range of different compositions that meet this requirement, so choosing the right one is a simple task.

Manufacturers responsibly approach the creation of their product, wanting to satisfy customers, generously fill it with plasticizers and additives. They improve the quality so that plastering the walls in the bathroom is easy.

When choosing between dry plaster and cement-sand, it should be remembered that the first is much easier to apply, cracks are extremely rare and it will harden faster than the second.

Just a week after application, work on the bathroom can continue with tiling or puttying.

Among other things, it is worth noting a colossal number of positive points:

Interesting: These mixtures are forbidden to be used on gypsum bases, foundations (from the influence of groundwater) and in the form of waterproofing plinths.

Preparation and application.

Waterproof plaster for the bathroom begins to be applied with the correct preparation of the wall, the further appearance and quality of work depends on this. It is imperative to remove the remnants of the old paint and plaster compositions. As for new buildings, the presence of grease stains and dirt is inevitable, so new houses require especially thorough cleaning:

The easiest way to remove the remnants of old paint is by burning with a blowtorch, however, this must be done by wearing a protective mask in order to avoid poisoning and possible minor burns of the mucous membrane. You can remove paint using folk ingenuity. Take 8 parts of the lime mixture and mix with 2 parts of caustic soda - you're done.
Walls that have a too even surface should be treated with a notch or cutting. Thanks to this action, the solution keeps much stronger.

Important: along with the listed processing methods, sandblasting can also be supplied. Thanks to him, the work will go much faster.

Owners of brick walls with filled seams need to make a notch in advance, scratching depressions about 1.5 cm deep. Appearing dust must be eliminated. Those whose walls have unfilled seams can safely take up the application, because the roughness will already be enough.

Spray.

Spraying is necessary to ensure the greatest adhesion of the mixture to the wall surface, due to the filling of all sorts of cracks and other irregularities.
The first thing to do is, of course, the spray. For it, they use a liquid solution, its consistency resembling sour cream:

First, the base must be thoroughly moistened with water.
Then, in the usual way of "throwing" the wall is covered with the mixture. The thickness must be within 5 mm.
The layer obtained by spraying should be left as it turned out.

Interesting: The wooden base requires more attention and the thickness can be increased to 9 mm.

Black layer.

Finish layer.

The finishing part can be divided into 2 types: processing the walls with a mixture for further finishing (it occurs when plaster is needed for the bathroom under the tiles), or using it as a decorative material.
The key difference between these options is: the careful choice of the substance and the thickness of the application of the solution. Decorative plaster for the bathroom is applied with a thickness of 4-7 mm, when the usual one is less than 2 mm:

First, it is important to moisten the rough layer of plaster
Then the professionals take on a wide spatula, with the edge of which they scoop up the finished mixture and spread it evenly on the wall. Holding the spatula at an angle of 15-20 degrees will achieve the best effect.
The layer that has not yet had time to grab is rubbed using a grater. Circular movements.

Important: When rubbing the protrusions, it is important to press the grater more tightly, rubbing the recesses, slightly squeeze.

Those planning to use it should remember that the texture is applied to the draft layer with a narrow spatula (from 8 to 12 cm). It is much easier to work with it, creating unique patterns and ornaments. It is necessary to move the spatula, however, the direction in this case plays a small role, so you can do it as you like.

Mandatory: Those who want to make a work of art out of their bathtub undoubtedly need to remember their own health, otherwise there will be no one to admire. Therefore, it is important to use gloves and a gauze bandage, especially if gypsum plaster is chosen in the bathroom.

Among other things, be sure to monitor the level of humidity and temperature, because it is obvious that at a higher temperature, waterproof plaster for the bathroom will dry much faster.
Upon completion of all technological processes, the tools must be washed, and the remaining material should be put aside in a convenient place, closed.

Nuances.

A solid base is an important detail of any work, thanks to which the plastering of the walls in the bathroom will be a pleasure. Having a wall cleaned of grease and wallpaper residues, you can get a bonus to the beauty of the work, even its strength and stability.

You should always pay special attention to the initial work, in this case it is extremely important to get rid of weaknesses in advance. Cracks in the walls, hated by many, only in the case of waterproof bathroom plaster play such an important role that you can gradually fall in love with them. In general, it is desirable to even deepen and expand them.

Those who have ugly efflorescence on the walls should be completely unceremoniously dealt with them with a steel brush, and special efflorescences that have captured large territories can arrange a genocide with a grinder with a brush in order to leave the wall of the house alone. 24 hours before plastering the walls in the bathroom, be sure to cover the wall with spray, an activity that is as useful as it is fun.

By the way, you should remember about the reinforcing mesh, because without it, some types of wall plaster in the bathroom will hold very weakly, among them gypsum plaster can be distinguished. For those who are interested in which plaster is best for the bathroom, it is easy to immediately answer that you can use any, but they try to avoid gypsum.

In general, tiles are rarely installed on gypsum plaster in the bathroom, because there is a danger of water getting between the seams and then you have to redo it again. The liquid will simply “eat through” the entire gypsum layer.

When mixing the dry composition of the mixture, use clean, preferably drinking water. The permissible degree Celsius is between 15 and 20. Slowly, portionwise pouring the mixture and stirring in parallel, it will be possible to achieve the ideal consistency.

Based on the required layer thickness, the density of the mixture is regulated. Easy to adjust, just add water. By the way, it is desirable to work out the finished solution in 20 minutes, since long inactivity will lead to a deterioration in quality and porosity.

Regarding brickwork, there is such a subtlety: first, the seams are clogged, and then, immediately, they are covered with the main layer of plaster. The solution is applied in different ways, you can do it manually, or with the help of special devices, from one or more visits.

Be sure to follow the drying of the plaster, this process must be completed no earlier than 24 hours.

There are absolutely no restrictions on the types for use. The only thing worth considering is this.

Before finishing the walls in the bathroom with decorative plaster, it is necessary to additionally waterproof the walls by working with a special primer to impregnate the working surface.

Compositions containing natural wax have positive qualities, so it is necessary to give preference to them so that the appearance pleases for many years. Today, one of the most applicable can be called a structural facade mixture, since it is incredibly resistant to high humidity.

Before starting plastering work, it is necessary to prepare the work surface. Decorative plaster in the bathroom with your own hands applied to the wall will reward anyone who is lucky enough to apply it with a real pleasure. This is more of a real art than hard work. In principle, the preparation of the wall for plastering is completely identical to the standard one.

First you need to clean the wall, remove dust, dirt, oil stains, prime it in the same way, but at the very end of the wall decoration, in order to get the main advantages of decorative plaster in the bathroom, you need to do special actions. Immediately after the solution has completely dried on the wall, it is important to cover it with mastic. It is designed to increase wear resistance and its action is aimed at eliminating moisture problems.

The main component of mastic is natural wax. Due to special processing during the manufacture of the mixture in production, it retains its shine and overflow. That is why, the base on which the decorative plaster for the bathroom is used has the appearance of a smooth, glossy surface, which adds.

Among other things, those who wish to use such plaster have the opportunity to choose almost any pattern or texture. The only problem you may encounter is your own imagination, but people who think creatively will definitely experience the pleasure of work.

Textured plaster in the bathroom.

For those who think what kind of decorative plaster in the bathroom looks best, we recommend paying attention to textured plaster. It consists of binders and filling components. The role of filling elements is played by: granules, pebbles and much more. Thanks to them, an extraordinary result is obtained, outwardly resembling a transfusion, or the strength of a stone, it can even be a metallic cold.

This mixture will simply lie on the wall, last a long time and with high quality, the cost will please, however, during application it is necessary to show maximum care and vigilance. There are cases of oversight, followed by many small, but unpleasant defects. It is important to carefully level the work surface.

Those who wish to make cosmetic repairs over time will find it difficult to remove the coating. On the one hand, this is undoubtedly excellent, it speaks of quality, however, if repairs every 2-3 years are the norm, then it is worth considering whether the extra hassle and the expenditure of the necessary strength are needed.

Among the proposals there are 2 options for this plaster - under the relief roller and under the grater. The pattern appears due to the fillers listed earlier. It is important to carefully consider the shape of the filling elements, since a round one will make a pattern in the form of grooves and grooves, sharp elements will create a scratched and streaked pattern.

Venetian plaster.

This plaster in the bathroom is applied exclusively in layers. The application of Venetian plaster is very different from ordinary plaster, because it requires special care, it can be applied only in a thin layer in order to achieve translucent layers as a result.

The translucency effect is what attracts people to the Venetian. It visually adds space, volume and depth to any room, thanks to the mirror-like sheen of the walls, which is close to ideal. Professionals with vast experience in working with Venetian plaster are able to literally make a mirror out of the working surface!

The places where the Venetian comes in contact with other materials, such as glass or ceramic tiles, must be treated with moisture-resistant compounds. This task is easily performed by an ordinary sealant, the price is small, and the usefulness is enormous.

It completely eliminates the risk of moisture penetration. The finished surface must be even, otherwise it is important to immediately eliminate the shortcomings while the mortar can be corrected.
