GRUNDER acrylic wall primer

Grunder is an acrylic, water-soluble priming and penetrating agent intended for covering building surfaces both indoors and outdoors, as well as those exposed to the damaging effects of weather conditions. Grunder acrylic wall primer is recommended for use under ordinary emulsion and acrylic paints, heavy vinyl and fiberglass wallpapers, and ceramic wall and floor tiles. After drying, it gives a transparent layer. It can be used on a variety of building materials, such as:

• plaster
• concrete
• bricks
• gypsum
• wood and wood-based materials
• gypsum cardboard plates

When used correctly, it increases the adhesion, unifies the absorbency and cohesion of the substrate, without hindering the so-called "wall breathing". It is certified by the National Institute of Hygiene , according to which it can be used for priming plasters and concrete surfaces outside and inside: residential premises, public buildings, health care, warehouses and production rooms, including in the food industry (without direct contact with food).

Acrylic wall primer Grunder - surface preparation and application:

The surface to be primed should be thoroughly cleaned, loose paint flakes removed and degreased. Fresh cement-lime plaster can be painted no earlier than 4 weeks after application. Matte smooth surfaces with sandpaper. Fill holes and cracks with acrylic putty, e.g. Biel-Putz , larger ones inside with plaster, outside with cement mortar. Depending on the absorbency of the substrate, use it without dilution or dilute it with water in a ratio of 1:1, i.e. 1 part of the preparation to 1 part of water. Before painting, mix the contents of the package thoroughly. Do not allow any shine or streaks to appear on the walls. Primer should not be added to the paint! If the substrate has small pores, we recommend Sil-Grunt, .
