Latex filler: properties and application
Latex putty refers to paint and varnishmaterials that are used to align various surfaces before paint is used. Usually the solution is applied after rough leveling with a plaster mixture of large drops or irregularities.The material is spread with a thin layer, since the latex filler can not withstand a thickness of more than a few millimeters, besides, excessive application increases costs due to the high cost of the product.
The composition of putty includes pigments (zincwhite, ocher, etc.), fillers (barite, chalk, talc, etc.), as well as a variety of film-forming substances. With a small number of components forming a film, the agent is no longer able to provide a quality equalization, in such cases it is used on a primer.
Latex putty has gained special popularitylately. This filling, leveling, quick-drying material is used for both external and internal finishing works. The product is used in the filling of concrete, primed, wooden, plastered and metal surfaces. Work with the solution is possible and in rooms with high humidity (semi-basement).
The standard thickness of the layer can reach 3 mm. If it is necessary to seal various holes, joints, riveted or welded joints, the material must be applied in layers, the thickness of which should be up to 1 mm.
Latex putty does not have toxicity,however, in case of contact with eyes, they should be rinsed, and it is better to work with glasses and protective gloves. Before use, the material must be diluted with water, then thoroughly mixed, and the temperature of the working surface and air should be above 5 degrees Celsius.

After applying the layer, the surface is practically notit is necessary to grind. The most popular putty Knauf uses in engineering and construction. For sale, it is packed in plastic buckets at 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 a greater cold, the material is stored for no more than a month.
The agent has the following positivefeatures. First, the putty makes it possible to create a thin layer with a smooth surface. Secondly, the material has a high elasticity, which ensures the uniformity of the application. It has exceptional adhesion to different substrates, creates a vapor-permeable coating. Due to the use of the product, the consumption of the following decorative materials is reduced.
