Primer A Eco 5kg Adhesion primer

Professional water-soluble concentrated insulating material for high-tech surfaces.

• Suitable for neutralizing the chemical swelling reaction of plasters and mortars based on gypsum or anhydride when in contact with cementitious adhesives.
• It reduces and regulates the water absorption of substrates with high porosity and stabilizes the surface composition by stabilizing the powder.

• TOTAL PROTECTION OF PLASTER :

Placing surfaces based on calcium sulphate exhibit, in the presence of moisture, a chemical swelling reaction which compromises the stability of the lining when in contact with mortars containing clay and silicate calcium hydroxides. PRIMER A technology creates a cohesive and insulating film for the complete protection of gypsum or anhydride substrates guaranteed by the use of special polymers of high chemical stability dissolved in water.

• ADJUSTS ABSORBENCY AND STABILIZES THE POWDER :

Gypsum or anhydride substrates, cement mortars and cement-based plasters very often show high absorbency and excessive surface dust, facts sufficient to not guarantee a professional installation. PRIMER A technology works through special polymers of high molecular weight, which enhance adhesion, ensuring the regulation of water absorption and surface stabilization of the substrate, for a fast and sure installation.

• NATURAL WATER BASED:

PRIMER A does not emit fumes harmful to health and the environment, therefore it can be applied indoors without contraindications. PRIMER A technology ensures an excellent workability in every case, which is guaranteed by the wide selection of dilution ratios with water, based on the specific characteristics of the substrate
