Directions
Read the entire label before use. Follow the directions strictly. Always test in a small, hidden area with a 24-hour cure time to check application ease and results. Let new grout installations cure for at least 72 hours before applying. Ensure the surface is clean, dry, and free of waxes and coatings. The surface temperature should be between 35°F and 90°F. Keep children and pets away until normal foot traffic resumes.
1. Mask any surfaces you don't want to treat.
2. Apply an even coat generously with a bristle paint brush or paint roller.
3. Let the sealer soak into the surface for 15 - 20 minutes. Spread any excess sealer across the area for even penetration. Don't let it pool on the surface.
4. Wipe the whole surface thoroughly with a clean, dry cloth to remove all excess sealer. Don't let the excess dry on the surface.
5. Wait for the sealer to fully cure before water touches the surface. It takes 72 hours to fully cure. If it might rain within 72 hours, cover the surface to keep it dry.
6. Clean the tools used during application with water.
7. If you also want resistance to oily stains, apply DuPont™ StoneTech® Professional BulletProof® Sealer after the Saltwater-Resistant Sealer has fully cured.

This StoneTech saltwater-resistant sealant is great for protecting concrete, stone, and masonry surfaces from saltwater damage. Here's how to use it: First, read the whole label and do a small test in an inconspicuous area for 24 hours. Make sure new grout has cured for at least 72 hours. The surface should be clean, dry, and between 35°F and 90°F. Mask off any areas you don't want to treat. Then, use a brush or roller to apply an even coat. Let it soak in for 15 - 20 minutes and spread the excess. Wipe off all the extra sealer. Wait 72 hours for it to fully cure. Keep it dry if it might rain. Clean your tools with water. If you want extra protection against oily stains, apply another sealer after this one has cured. When using, keep kids and pets away until it's safe for foot traffic. And remember, it might slightly darken natural concrete. If you have any questions, reach out to our experts.
