Ask a question about this product

Professional, superior technology, concentrated water-base surface insulation product that neutralizes the expansive chemical reaction of gypsum or anhydrite-based plasters and screeds on contact with cement-based adhesives. Reduces and regulates the absorption of water in highly porous substrates, stabilizing the surface consistency by suppressing the dust.

TOTAL PROTECTION OF GYPSUM – In the presence of moisture, substrates with a calcium sulphate base trigger an expansive chemical reaction that impairs the stability of the covering on contact with mortars containing aluminates and calcium silicate hydrates. The PRIMER A technology creates a cohesive insulating film that fully protects gypsum or anhydrite substrates, guaranteed by the specific and chemically stable polymers dispersed in water.

REGULATES ABSORPTION AND SUPPRESSES DUST – Substrates with a gypsum or anhydrite base and cement-based screeds and mortars very often present high absorption levels and form high amounts of surface dust, preventing them from achieving professional laying performance. The PRIMER A technology acts through the specific adhesion-promoting polymers with high molecular weight that regulate water absorption and consolidate the substrate surface, thereby guaranteeing fast, safe laying.

NATURAL, WATER-BASED – PRIMER A does not give off fumes that may be harmful to humans or to the environment. Hence, it can be safely used with no contraindications in indoor environments. The PRIMER A technology ensures excellent workability in all conditions thanks to the wide water dilution range, depending on the specific characteristics of the substrate.

AREAS OF USE

Professional, concentrated water-base insulation product for gypsum and anhydrite substrates before ceramic tiles are laid using cement-based adhesives or before paint is applied to walls.
