Properties

Description

TEROSON® PR PRIMER M+S is a specially developed adhesion promoter that forms a permanent bond with the substrate. It produces a load-bearing surface to ensure a durable bond with TEROSON sealing strips. Sealing strips plus primer form a system of perfectly matched components. On porous and mineral substrates, PR PRIMER M+S is used to produce a load-bearing surface.

SUBSTRATE PREPARATION

Mineral substrates must be load-bearing, sound and free of oil, grease and release agents. The building substrate should be smooth and even. Before applying the primer, remove any impurities, sintered layers, concrete fins or ridges, mortar residues or loose parts.

APPLICATION:

TEROSON PR PRIMER M+S is applied by roller or paste brush on the mineral substrate. Substrates with a high dust load must be cleaned before applying the primer, e.g. with a scrubbing brush, hand brush or vacuum cleaner. TEROSON PR PRIMER M+S can also be used on damp substrates (construction moisture). After application, allow the primer to flash off for approx. 20-50 minutes, depending on temperature, substrate and air humidity.
