Sea Hawk S-90 De-Waxing Etch & Cleaner, Water-Based Surface Prep Cleaner, S-90GL
Sea Hawk S-90 De-Waxing Etch & Cleaner, Water-Based Surface Prep Cleaner, S-90GL
Sea Hawk S-90 De-Waxing Etch & Cleaner is a concentrated, water-based de-wax etch and cleaner formulated for deep-penetrating removal of tough surface contaminants before painting or coating a boat hull. Its penetrating action breaks down oil residues, wax, mold spores, and general surface soiling, leaving a clean substrate that promotes good adhesion for primers and antifoulants. Because it is water-based rather than petroleum-based, S-90 is safer to use and lifts stubborn contaminants with minimal scrubbing effort.
S-90 is formulated without harsh chemicals and contains no methylene chloride, and it is water based and biodegradable. It can be used for general cleaning of virtually all surfaces, and is safe for cleaning painted surfaces when used properly. For general cleaning, apply generously with a cloth towel and gently rub to remove contaminants, then rinse away with clean water. For de-waxing with etch prior to coating, apply a thick wet coat using a china bristle brush or a solvent-resistant roller cover with 3/8 inch nap, then work the surface with a Scotch-Brite 7447 pad in circular motions to create scratch/profile ahead of primer or antifoulant application. Allow the product to work for 3-5 minutes before rinsing away with clean water.
