Deep-penetrating priming preparation, concentrate 



SIL- GRUNT is a deep penetrating, water-based primer preparation intended for indoor building surfaces (regardless of the degree of moisture ) and the exterior of buildings. Properly applied, it raises the adhesion, strengthening capacity, standardization of  consistency asnd  the absorbency of the substrate, while not hindering the process of so-called  " breathing ". Prevents discoloration and stains. Reduces the wear of topcoats.

It is recommended for use under high-quality latex and  silicone paints, plain acrylic and emulsion paints, heavy vinyl and glass fiber wallpaper, waterproofing compounds, acrylic plasters, ceramicwall & floor tile, and priming before pouring self-leveling floors. It can be used for a variety of construction materials, like plaster, concrete, brick, plaster, wood and wood-based materials and plasterboard.

It is equired under the Waterproofing compound IZOLANIT,  under  the silicone-acrylic concrete paint, roofing paint and the color paint SILANIT 100 ( when the substrate is not uniform in terms of absorbency and moisture content, eg due to repairs ).



Properly applied, it raises the adhesion of paint, improves standardization and consistency of the absorbency of the substrate, at the same time does not interfere with the process of the so-called. "wall breathing". In the case of fresh plaster it does not impede the curing process, and under color coating  prevents stains and discoloration. These features are the result of the application of the particulate polymer with an extremely small particle size (so called hydrosol)  that are many times smaller than those used in conventional acrylic primers. This ensures deep penetration into the porous substrate.


Surface preparation and application:

For new plaster there is no need for special preparation of the substrate, only traces of oil must be removed after the formwork. Surface for renewal should be carefully dusted, cleaned, loose patches of paint removed and surface degreased. Completely remove lime and dry glue paints. Eliminate algae and mold with chemical substances. Smooth surfaces are roughened with sandpaper. Fill cracks with acrylic filler, larger gaps : interior with plaster, on the exterior and under mineral paints use cement mortar. Paint the protruding and not removable steel elements with anticorrosive paint. Mix package contents thoroughly. Depending on the absorbency of the substrate SIL- GRUNT can be diluted with water in a ratio of 1:1 to 1:4 (i.e., 1 part of the formulation, and 4 parts water). Fresh cement-lime plaster painted no earlier than 3-4 weeks after application. Avoid excess of  paint. Do not allow the formation on the surface lacquering and stains.


Safety precautions:

In the event of contact with skin, wash with soap and water. Flush eyes with plenty of running water, in case of irritation symptoms, contact your doctor. Keep out of reach of children.
