Modern renovation is unthinkable without the use of new materials developed on the basis of artificial components. When finishing rooms with a high level of humidity, special mixtures are used that protect surfaces from destruction, the formation of fungus and mold. Moisture-resistant putty occupies a special place among bulk building materials.
Characteristics and properties of moisture resistant putty
The dry mix used to create a moisture-resistant putty contains special synthetic components. Thanks to these additives, a coating is created that prevents:
- condensation;
- various kinds of leaks;
- release and accumulation of moisture;
- penetration of water droplets into the main surfaces;
- mold and fungus.
The use of moisture-resistant compositions allows you to save the building structure and create favorable conditions for the functioning of the premises itself and the comfort of people.
Moisture-resistant putty refers to high-strength building materials. In addition to the waterproof effect, it has durability and reliability. Manufacturers guarantee the safety of the coating with such putty for at least 20 years.
It is resistant to changes in air temperature and does not respond to rising and falling degrees. This property allows you to securely hold the finish coating, which is used as a tile or mosaic.
Types and compositions of putties
Depending on the nature of the finishing work and the characteristics of the room, different types of waterproof putty are chosen.
- The cement mixture is based on Portland cement. This material is durable and reliable, which is especially important for wet rooms. When interacting with water, its properties improve. To make the powder composition even better, crushed marble chips, artificial plasticizers and hardeners are added to it. All these components give putty special performance characteristics. Since this mixture has a dark gray color, it is used for starting finishing of brick walls and concrete floors.
- Gypsum putty with polymer components has excellent water resistance. Synthetic elements in it are necessary to be able to work with such a mixture for a certain time, since natural gypsum quickly hardens and turns into crumbs. Such putty seal the seams and joints between individual parts and elements of the building structure.
- Acrylic waterproof putty is a fully synthetic mixture specially created by scientists for finishing wet rooms. It is used as a finishing coat when leveling walls in bathrooms and kitchens for painting or wallpapering. With the help of this composition, designers decorate surfaces by drawing a pattern on a wet layer of putty. It is a durable, practical and crack-resistant material. Polymer products include latex putty, which has the same properties as acrylic.
- Oil-adhesive putty, consisting of glue and drying oil, is widely used in wet areas to eliminate cracks and other defects in the bases. It is sold in paste form and is initially ready for use. This material is intended for finishing walls and ceilings, which will be painted or tiled.
Whatever the type of putty, it should dry quickly, hold firmly on the surface, create a smooth and smooth coating to the touch. It should not absorb water, repelling it. For the bathroom, putty with moisture-resistant properties is an indispensable material.
How to use moisture resistant putty
Most manufacturers of building mixtures produce dry formulations that must be diluted with water before use. How to do this is written on the package. If you strictly follow the instructions, you can get a guaranteed excellent material for finishing walls and ceilings in the bathroom or shower.
Among buyers, the products of well-known brands are the most popular: Knauf, Vetonit, Osnovit and others. They produce products of high quality and remarkable characteristics. To putty the walls and ceiling in the bathroom, choose the starting and finishing mix of the same brand. They will have maximum compatibility and the final layer will lay down evenly and beautifully.
Before applying the paste composition to the surfaces in the bathroom, they are carefully prepared. At the same time, all major damage and defects are eliminated, seams and deep cracks are sealed. It is important to thoroughly clean the walls and ceiling from dirt, cement and brick deposits.
Under the putty layer, it is necessary to apply liquid primer, let it dry and form a film. It will not allow the base material to soak into the base and provide good adhesion to it. In damp rooms, the likelihood of the formation of a parasitic environment is high. Primer and treatment with antiseptics will save surfaces from fungus, mold and harmful insects.
- Moisture-resistant cement-based putty is an excellent mixture for starting finishing in the bathroom. A thick mixture is applied to a pre-prepared brickwork or concrete base in a thick layer and carefully leveled with a facade spatula. It reliably hides the defects of the base and allows you to create an absolutely even coating.
- When the primary layer is completely dry, it is primed with a liquid composition, the liquid is allowed to soak in and the finishing layer of putty is applied. It should be like a paste that will smoothly cover the base.
- After the last layer has dried, the walls and ceilings in the bathroom sanding and smooth down.
When using a moisture-resistant putty, a coating that is pleasant to the touch without signs of liquid should be obtained. A tile or mosaic is attached to it. Ceramic products are securely held on it for a long time, do not fall off and do not deteriorate even in constantly damp rooms. The walls and ceilings in the bathroom trimmed with such material can be painted with polymer paints or pigment compositions can be immediately added to the mixture, creating a certain shade.
