Where and how to use moisture resistant putty

Modern repair is not conceivable without the use of new materials developed on the basis of artificial components. When decorating rooms with a high level of humidity, special mixtures are used that protect surfaces from destruction, the formation of fungus and mold. A special place among bulk building materials is moisture-resistant putty.

Characteristics and properties of moisture resistant putty

The dry mix used to create moisture-resistant putty contains special synthetic components. Thanks to these additives, a coating is created that prevents:

• condensation;
• various kinds of leaks;
• moisture release and accumulation;
• the penetration of water drops into the main surface;
• mold and mildew.

The use of moisture-resistant compounds allows you to save the building structure and create favorable conditions for the functioning of the premises and the comfort of people.

Moisture-resistant putty is a high-strength building material. 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 increasing and decreasing degrees. This property allows you to reliably 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 true for wet rooms. When interacting with water, its properties are improved. To make the powder composition even better, crushed marble chips, artificial plasticizers and hardeners are added to it. All these components give putty special operational 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 in order to be able to work with such a mixture for a certain time, since natural gypsum quickly hardens and turns into crumbs. Such putty seams and joints between separate parts and elements of a building construction are closed.

• Acrylic waterproof putty is a fully synthetic mixture specially created by scientists for finishing wet rooms. It is used as a topcoat for leveling walls in bathrooms and kitchens for painting or wallpapering. Using this composition, designers decorate surfaces by applying a drawing on a wet layer of putty. It is durable, practical and crack resistant. Polymer products include latex putty, which has the same properties as acrylic.

• Oil-glue putty, consisting of glue and drying oil, is widely used in wet rooms to eliminate cracks and other defects of the bases. It is sold in pasty form and is initially ready for use. This material is intended for the finishing of walls and ceilings that will be painted or tiled.

Whatever the type of putty, it should dry quickly, hold firmly to the surface, create a smooth and smooth to the touch coating. It should not absorb water, pushing it away. Putty with moisture resistant properties for the bathroom is an indispensable material.

How to use moisture resistant putty

Most manufacturers of building mixtures produce dry compositions, which must be diluted with water before use. How to do this is written on the packaging. If you strictly follow the instructions, you can get guaranteed excellent material for decorating walls and ceilings in the bathroom or shower.

Among buyers, products of well-known brands are most popular: Knauf, Vetonit, Osnovit and others. They produce high quality products and great features. To putty the walls and ceiling in the bathroom, choose the starting and finishing mixture of the same brand. They will have maximum compatibility, and the last layer will lie evenly and beautifully.

Before applying the paste composition on the surface in the bathroom, they are carefully prepared. At the same time, they eliminate all major damage and defects, close the seams and deep cracks. It is important to thoroughly clean the walls and ceiling of dirt, cement and brick sediment.

Under the putty layer, it is necessary to apply liquid soil, allow it to dry and form a film. It will not allow the base material to be absorbed into the base and will provide good adhesion with it. In humid rooms, a parasitic environment is likely to form. Primer and treatment with antiseptics will save surfaces from fungus, mold and harmful insects.

• Cement-based moisture resistant putty is an excellent mixture for starting finishing in the bathroom. A thick mixture is applied to a previously prepared brickwork or concrete base with a thick layer and carefully leveled with a facade trowel. It reliably hides base defects and allows you to create a completely even coating.

• When the primary layer is completely dry, it is primed with a liquid composition, the liquids are absorbed and a finishing layer of putty is applied. It should look like a paste that will smoothly cover the base.

• After the last layer has dried, the walls and ceilings in the bathroom sand and smooth out.

When using moisture-resistant putty, a pleasant-to-touch coating without signs of liquid should be obtained. Tiles or mosaics are attached to it. Ceramic products reliably hold on it for a long time, do not fall off and do not deteriorate even in constantly humid rooms. The walls and ceilings in the bathroom finished with such material can be painted with polymer paints or pigment compositions can be added to the mixture immediately, creating a certain shade.
