When APPLYING Dow Corning 1200 PRIMER, the following steps must be followed to obtain the bonding effect:
All dust, dirt, oil stains and other impurities must be completely removed on the surface of the sealant. Use sandpaper or a wire brush to scrub or remove rust from metal surfaces. The masonry surface should be brushed clean with a wire brush, while dust is blown away with high pressure air.
◆ With a clean cloth that does not contain oil stained with petroleum brain (Naphtha), Mineral Spirits, Xylene, Toluene or methyl acetylene (MEK) and other industrial solvents, the material surface oil thoroughly wipe wipe.
◆ Apply Dow Corning 1200 primer to a clean, dry building surface using a cloth, brush, or spritzer. Approximately 400 square feet per gallon can be applied to materials with rough or porous surfaces, and 800 square feet per gallon for smooth metal or plastic surfaces.
Let the solvent contained in the primer completely volatilize. The duration of evaporation depends on temperature, humidity and the porosity of the coating material.
◆ Apply Silicone construction sealant according to instructions.
