Clean all joint cavities, removing all foreign matter and contaminants from substrates such as grease, oil, dust, water, frost, surface dirt, old sealants or glazing compounds and protective coatings. Joints to be sealed should be dry and moisture free.
Apply DOWSIL™ 757 Sealant and tool it within 30 minutes or before a cured skin forms to ensure good contact with between the sealant and the substrate. Tooling of the sealant also gives a smooth professional finish. Remove the masking tape as soon as the bead is tooled.
In areas where uncured sealant is inadvertently applied to adjacent surfaces, the sealant should be cleaned from surfaces before curing, using a good quality alcohol-based solvent.
