PRIMER 3500

PRIMER 3500 Waterborne acrylic primer with ultrafine particle size to provide deep substrate impregnation.
Improves adhesion and reduces absorption.
Designed for porous substrates and resistance to alkalinity, PRIMER 3500 improves adhesion of the subsequent reactive coating layer and enhances substrate cohesion of concrete, reinforced concrete, masonry. Saturation of substrate porosity results in lower water absorption during coating application, increasing open time, improving flow and levelling.
Thin as specified and apply the right amount to obtain substrate saturation while avoiding excess. No film should appear on the surface after drying.
Specifically tested in EN 13381-3 fire tests for perfect performance of CHAR 21.
