HOW-TO > PROJECT TIPS > Thompson's® WaterSeal® Deck Cleaner & Brightener
- Add contents of container to a plastic bucket or plastic pump-up sprayer. Do not use a metal container.
- For ease of application, apply Thompson's® WaterSeal® Deck Cleaner & Brightener with a pump-up sprayer, or use a synthetic bristle brush or roller.
- Apply to no more than 5-10 boards (20 sq. ft.) at a time to maintain adequate surface wetness and allow best results. Immediately and thoroughly rinse any overspray or accidental spills with water.
- Allow Thompson's® WaterSeal® Deck Cleaner & Brightener to remain on wood for 10-15 minutes. For best results, lightly scrub surface with a stiff, synthetic bristle brush. Do not let Thompson's® WaterSeal® Deck Cleaner & Brightener completely dry during application.
- Thoroughly rinse the surface with a garden hose or pressure washer, removing all residue. After rinsing the surface, be sure to saturate the ground around plants and shrubs with fresh water.
- Stubborn stains or missed areas may need to be scrubbed with additional Thompson's® WaterSeal® Deck Cleaner & Brightener and rinsed again.
