Akrylowy preparat gruntująco-penetrujący, koncentrat (1:2)



GRUNDER is a water-based acrylic primer designed to cover surfaces of  building interiors, as well as exterior surfaces that are vulnerable to the devastating effects of the weather. It is recommended for use under ordinary emulsion and acrylic paints, heavy vinyl & glass fiber wallpaper, ceramic wall and floor tiles. The primer gives a dried transparent layer. It can be used for a variety of construction materials, like plaster, concrete, brick, plaster, wood and wood-based materials, plasterboard. Properly applied, it raises the adhesion, cohesion and uniformization of absorbency of the substrate, while not hindering the process of so-called. "wall breathing".


Surface preparation and application:

The surface to be primed requires a thorough cleaning, removal of  loose patches of paint and degreasing. Fresh cement-lime plaster can be painted no earlier than 4 weeks after application. Smooth surfaces are to be roughened with sandpaper. Fill holes and cracks with acrylic filler, larger ones with plaster in the interior and cement mortar on the exterior. Depending on the absorbency of the substrate use diluted with water in a ratio from 1:1 to 1:2, i.e. one part of the formulation to 2 parts of water. Mix the contents thoroughly before painting.

Do not allow the formation of lacquering and stains on the walls.
