S-90 De-Waxing Etch & Cleaner by Sea-Hawk is a concentrated water-based formula that penetrates deep to lift and remove contaminants from almost any surface. S-90 is effective at removing wax, oil residues, surface soiling contaminants and mold spores.
It also works well at etching the surface to promote good adhesion for anti-foulant paints and primers, eliminating the need to sand. S-90 is biodegradable and contains low VOCs and virtually no harsh chemicals (no methylene chloride).
General Cleaning: Apply cleaner generously with cloth towel and rub gently to remove contaminants. Rinse away the residue with clean water.
De-Waxing with Etch: Apply a thick wet coat by china bristle brush or a solvent resistant roller cover 3/8" pile smooth or medium to the surface. Use Scotch-Brite 7447 pad in a circular motion to get enough scratch to the surface before primer or anti-foulant. Allow the product to "work" for 3-5 minutes. Rinse away all residues with clean water.
