1. Mask and protect baseboards or nearby areas to avoid splashing.
2. You can apply the sealer to damp surfaces one hour after removing standing water.
3. Use a paint pad, low - pressure chemical - resistant sprayer, roller, or brush to apply an even coat generously.
4. Let the sealer soak in for 15 - 30 minutes. Spread any excess for even penetration and then wipe with a clean dry towel.
5. Porous surfaces may need a second coat 30 - 40 minutes after the first application, following steps 3 - 4.
6. After the final application, wait at least 15 minutes and wipe off excess sealer. Use a damp white nylon pad if there's residue and dry thoroughly.
