Plaster for the bathroom, options and application features

The bathroom is a room with a huge humidity coefficient. This fact is undeniable, so many factors should be taken into account when starting finishing. Most craftsmen, specialists and various experts with even a little knowledge agree on one opinion - tiles would be the ideal application option.

However, today we are interested in plaster under tiles in the bathroom, including on concrete walls, since it, like tiles, is able to cope with temperature changes, withstand colossal dampness and withstand the aggressive effects of steam.

What plaster to use in the bathroom, how to properly plan the work process, what moments deserve the greatest concentration? We will answer.

Sanitation solutions.

Bathroom plaster under tiles 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 take a responsible approach to creating their product, wanting to satisfy customers, generously filling it with plasticizers and additives. They improve the quality so that plastering bathroom walls is easy.

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

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

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

Interesting: These mixtures are prohibited from being 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 with proper preparation of the wall; the further appearance and quality of the work depends on this. It is imperative to remove any remnants of the previous 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 remnants of old paint is by burning it with a blowtorch, however, this must be done while 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 lime mixture and mix with 2 parts of caustic soda - ready.
It is advisable to treat walls with a too smooth surface by notching or slicing. Thanks to this action, the solution holds 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 that is important to do is, of course, spraying. For it, they use a liquid solution, its consistency resembling sour cream:

First, the base must be thoroughly moistened with water.
Then, using the usual “throwing” method, they cover the wall with the mixture. The thickness should be within 5 mm.
The layer obtained by spraying should be left as it was.

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

Rough layer.

Finishing layer.

The finishing part can be divided into 2 types: treating the walls with a mixture for further finishing (occurs when plaster is needed for a bathroom under tiles), or using it as a decorative material.
The key difference between these options is: careful selection of the substance and the thickness 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 wet the rough layer of plaster
Then the professionals take a wide spatula, use the edge of which to scoop up the finished mixture and spread it on the wall in an even layer. Holding the spatula at an angle of 15-20 degrees will achieve the best effect.
The layer that has not yet had time to set is rubbed using a grater. Circular movements.

Important: When rubbing the protrusions, it is important to press the grater more firmly, while rubbing the grooves, squeeze out lightly.

Those planning to use should remember that the texture is applied to the rough layer with a narrow spatula (from 8 to 12 cm). With its help it is much easier to work, 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 however you like.

Mandatory: Anyone who wants to turn their bathtub into a work of art undoubtedly needs to remember about their own health, otherwise there will be no one to admire it. 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 bathroom plaster will dry much faster.
Upon completion of all technological processes, the tools must be washed, and the remaining material must be put away in a convenient place, closed.

Nuances.

A solid foundation is an important part of any job and makes plastering your bathroom walls a pleasure. Having a wall cleaned of grease and wallpaper residues can add strength and stability to the beauty of the work.

You should always pay special attention to the initial work, in this case it is extremely important to get rid of weak points 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 advisable 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 on very weakly, gypsum plaster can be distinguished among them. 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 mixture, use clean, preferably drinking water. The permissible degree Celsius is between 15 and 20. Slowly pouring the mixture in portions and stirring at the same time will achieve the ideal consistency.

Based on the required layer thickness, the thickness of the mixture is adjusted. Adjustment is very simple, you just need to add water. By the way, it is advisable to prepare the finished solution within 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 hammered in, and then, immediately, they are covered with a main layer of plaster. The solution is applied in different ways; you can do it manually, or using special devices, in one or more passes.

It is imperative to ensure that the plaster dries; this process must be completed no earlier than 24 hours.

Among the proposals there are 2 variants of this plaster - for a relief roller and for a grater. The pattern appears thanks to the fillers listed earlier. It is important to carefully consider the shape of the filling elements, since round ones will create a pattern in the form of grooves and grooves, while sharp elements will create a scratched pattern in the form of streaks.

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 in an extremely thin layer to achieve translucent layers as a result.
