Dry-Treat Stain-Proof Plus is a premium impregnating sealer. It is specially formulated to provide long-term protection against water- and oil-based stains and damage. It’s specially formulated for natural stone and concrete countertops. Treating your countertops with Stain-Proof Plus makes them easier to clean, maintain, and preserve. Use it on basalt, bluestone, concrete, granite, marble, quartzite, and slate countertops. This sealer is suitable for indoor, outdoor, residential, and commercial use. It contains a super penetrator, which allows for deep penetration of dense granite and marble. It contains 3 different custom sealing molecules for 3 levels of penetration, maximizing stain repellence on your countertops. Stain-Proof Plus retains natural surface color and finish. It is super breathable, making it safer to use. It allows water vapors to escape freely, which prevents harmful moisture buildup inside the treated material. To use, make sure the target surface is dry and free of any residues, and then generously apply Stain-Proof using a low-pressure hand sprayer, clean brush, or lamb wool applicator. Porous surfaces should have a mirrorlike wet look. Avoid contact with surrounding areas. Wait for approximately 10 minutes, and then reapply the product before the surface dries. After the final coat, wait another 10 minutes, and then polish the surface before it dries. Polish it with a clean, dry white cloth, towel, or similar material to remove excess product. We recommend moistening the cloth with Stain-Proof Plus to ease polishing. Finally, use an organic solvent to clean equipment.
