SUBSTRATE PREPARATION

Sika® MultiSeal AP generally has strong adhesion without primers/activators to most dry, clean and sound substrates. For optimum the following procedure shall be followed:Non porous substrates :Metals, plastics, coated surfaces and glazed tiles have to be cleaned and pre-treated with Sika®Aktivator-205 by using a clean towel. Before sealing allow a flash-off time >15 min (max.6 hours).Porous substrates :Concrete, aerated concrete and cementitious plasters, mortars, brick, etc. have to be primed with a bituminous primer (e.g. SikaProof® Membrane) by using a brush. Before applying Sika® MultiSeal AP allow a flash-off time > 1 hour.
