Τhe product GLX 292 FLEX PRIM is an acrylic micronized water-based primer with high penetration properties. It is ideal for preparing any new or already existing porous surface, such as plaster, bricks, concrete, puttied walls, etc., thus offering perfect adhesion to acrylic plaster, water paints, mortars, tile adhesives, acrylic and cementitious waterproofing spreads, etc. It is the best solution for surfaces on which water colours, lime or low-quality old paints had been applied. It makes brittle surfaces (loose plaster, cement mortar, etc.) hard and prepares them for painting, plastering, etc. It also prepares difficult surfaces, such as plaster boards, wood, etc., for glueing ceramic tiles.

It presents high penetration abilities and reduces the capillary absorption coefficient, though without blocking the pores since it lets the surface “breathe.”
