Primer "Concrete contact Knauf": scope and rules of use

Modern construction is an arena for applying a variety of technological and technical novelties. Even in such an area as plastering walls , new products constantly appear, which increase labor productivity, improving the quality of processing. One of these novelties is the "Concrete Cotta Knauf" primer, which is a polymer dispersion with the addition of alkali-resistant sand. It is designed to treat surfaces that have a low absorbency, which can be a problem when plastering walls: over time, the coating exfoliates.

Primer "Concrete contact Knauf" is recommended for the processing of monolithic concrete, reinforced concrete ceiling slabs, prefabricated reinforced concrete products, plasterboard, plaster and lime-plaster plaster, before installing stucco decorations, for processing expanded polystyrene plates before plastering them, etc. Surfaces, Coated with this primer, have excellent adhesion capabilities, become denser and more durable. Use this kind of material and when gluing ceramic tiles on the tile, for the treatment of surfaces covered with oil paint before plastering, before puttying metal parts, etc.

Surface preparation and priming

Before using the mixture "Concrete contact Knauf", you need to prepare the surface: clean from dust, dirt and grease stains. Sell this material in buckets of 5 and 20 kg. Depending on the type of surface to be treated, it is possible to add or not to add water to the primer (not more than 1 liter per 20 kg). Before application, the composition must be thoroughly mixed and work can begin.

Primer "Concrete contact Knauf" (consumption - 250-350 g / m ² ) Very economical. It is applied with a brush or roller. Do not apply primer to cold surfaces or work with it at temperatures below +5 ° C. The temperature should also not fall below this level until the layer dries completely. During work, the composition should be stirred periodically.

Apply the putty only on the completely dry primer, but the gap between drying and the beginning of the putty work must be very small to prevent the dust from settling on the treated surfaces. After work, all tools should be washed: the fresh composition is washed off with water, dried - only with the help of mechanical cleaning.

Contraindications to use

Do not recommend using this product on surfaces with insufficient density, crumbling and unstable bases. Do not apply at low temperatures (below +5 ^о С) and on frozen surfaces.

Benefits

At a low price, the primer is of high quality, does not contain allergens and does not harm the environment, dries quickly, is convenient and easy to use. And all this - the primer "Concrete contact Knauf." Technical characteristics and reliability of plastered surfaces with it are much higher, this decoration lasts longer: it does not crumble and does not exfoliate, retaining an attractive appearance for a long time.
