Latex putty refers to paints that are used to level various surfaces before paints are used. Typically, the solution is applied after rough alignment with a plaster mixture of large differences or irregularities.
The material is smeared with a thin layer, since the latex putty may not withstand the thickness of more than a few millimeters, moreover, its excessive application increases the costs due to the high cost of the product.
The composition of the putty includes pigments (zinc white, ocher, etc.), fillers (barite, chalk, talc, etc.), as well as a variety of film-forming substances. With a small number of components that form the film, the tool is no longer able to provide high-quality alignment, in such cases it is used on a primer.
Latex putty has gained particular popularity recently. This filling, leveling, quick-drying material is used for both external and internal finishing work. The tool finds its application in the filling of concrete, primed, wooden, plastered and metal surfaces. You can work with the solution in rooms with high humidity (semi-basement).
Standard layer thickness can reach 3 mm. If it is necessary to seal various holes, joints, rivets or welds, the material must be applied in layers, the thickness of which should be up to 1 mm.
Latex putty is not toxic, but if it gets into the eyes, they should be washed, and it is better to work with glasses and protective gloves. Before use, the material must be diluted with water, then mixed thoroughly, while the temperature of the working surface and air should be above 5 degrees Celsius.
Before starting work, the wall should be cleaned of various contaminants (old paint, oil stains, dust), if necessary, the surface can be moistened with water. Such latex putty is produced, which is used only for the final decoration of walls and ceilings. This matte pasty material has high elasticity.
After applying the layer, the surface practically does not have to be ground. Knauf putty is most popular in mechanical engineering and construction. For sale, it is packed in plastic buckets of 1.5, 7, 15 and 28 kg., Where it can be stored for a year from the date of manufacture.
Latex putty should be only at a positive temperature, in an intact, tightly closed container, with more cold, the material is stored for no more than a month.
The tool has the following positive features. Firstly, the putty allows you to create a thin layer with a smooth surface. Secondly, the material has high elasticity, which ensures uniformity of application. It has exceptional adhesion to various substrates, creates a vapor-permeable coating. Thanks to the use of the product, the consumption of the following decorative materials is reduced.
