Mapei Primer M For Polyurethane Sealants 2kg

Primer M is used to improve the bonding of polyurethane sealants such as Mapeflex PU45, Mapeflex PU40, Mapeflex PU50 SL, and adhesives such as Ultrabond P990 1K and Mapegum PU 1K, on non-absorbent surfaces, such as metals (iron, steel, aluminium, copper, zinc-plated sheets), ceramic, glass and painted sheets or absorbent surfaces, such as concrete, etc. Primer M should also be used for joints that are in frequent contact with liquids for lengthy periods of time or exposed to high mechanical stress after they have been sealed. Primer M may also be used to promote adhesion on membranes from the Purtop line around joints that have been made in the membrane after the maximum covering time.
