KEIM Concretal-Fixativ is a high-performance, silicate-based primer and dilution agent designed specifically for mineral substrates like concrete. It works by deeply penetrating the surface, strengthening it, and improving adhesion for subsequent KEIM mineral coatings. When used as a dilution, it adjusts the consistency of KEIM concretal paints without compromising their breathability, durability, or color stability. Ideal for prepping new or weathered concrete surfaces, concretal-fixativ ensures a longer-lasting, more even finish.
