Betonokontakt primer is made on an acrylic base, quartz sand and mineral fillers. It is intended for preliminary treatment of dense, poorly absorbent moisture bases: monolithic concrete, concrete blocks, concrete ceilings, slabs, bricks, cement products, limestone materials both inside and outside buildings, plasterboard. It is used as a bonding primer before laying facing tiles, for walls, floors and ceilings. After application, it forms a rough coating with large particles to improve the adhesion of finishing layers to the base.
