PREMIUM GRANULATING PRIMER 4 KG - SIL GRU 4 S

Technical data Color: blue Drying time: 1-2 h Adhesion to concrete: min. 1 MPa Yield approx.: 150g/1m2 Working temperature: from +5 to +25 Premium bonding primer 4kg KONTAKT PREMIUM bonding primer is a ready-to-use preparation, based on acrylic dispersion with the addition of quartz aggregate. Increases the roughness of the substrate and strengthens and improves the adhesion of layers. On mixed substrates, it equalizes and regulates their absorbency. It is used, for example, in renovations without chiselling – in particular in installation systems for ceramic and stoneware tiles on old ceramic or stone cladding and with heated floors. Advantages: - increases the roughness and strengthens the substrate - contains quartz sand - high efficiency - ideal for use in tile-on-tile systems - renovation without chiseling - for use with heated floors - equalizes the absorbency of the substrate - for indoor and outdoor use, on walls and floors - for absorbent and non-absorbent substrates - for tight concrete, old tiles, terrazzo, OSB - ready to use Application - preparation of a rough bonding layer on non-absorbent substrates intended for pouring self-leveling compounds, applying putty, machine plasters, gluing ceramic tiles, etc. - for indoor and outdoor use on dry and seasoned substrates made of stripped concrete and reinforced concrete, prefabricated elements, old ceramic facings, gypsum boards, paint coatings (paneling), OSB boards, terrazzo and other tight mineral substrates ** Photos are for illustrative purposes only.
