Directions for use
Before you begin
- Thompson's® WaterSeal® Wood Stripper should NOT be used on new or untreated wood as it may cause the wood to "fuzz" or raise the wood's grain.
- A trial patch is recommended before starting. Test on an inconspicuous area before applying to entire surface.
- Product can be applied to dry or damp wood.
- Remove all deck furniture and decorative items that could come in contact with Thompson's® WaterSeal® Wood Stripper. Do not allow product to come in contact with aluminum, painted or finished surfaces you do not intend to restore. Protect glass from contact with product.
- Saturate the ground around plants and shrubs with fresh water prior to application. Then cover all plants and shrubs to protect them from contact with product. Uncover promptly after use.
- Prevent contact with eyes, skin and clothing. Wear impervious chemical-resistant rubber gloves and safety goggles during use. Do not allow Thompson's® WaterSeal® Wood Stripper to come into prolonged contact with carpet or fabric, as damage may occur.
- After application of Thompson's® WaterSeal® Wood Stripper, it is strongly recommended you use a wood brightener such as Thompson's® WaterSeal® Wood Brightener to neutralize the surface and allow for the best performance of your reapplied waterproofer or stain. Thompson's® WaterSeal® Wood Stripper may substantially darken Cedar, Redwood, and Hardwoods. Using a wood brightener will also help restore these woods' natural color and beauty.
- Plan the application: for horizontal surfaces, walk backwards as you work so you do not walk on the surface being treated. For vertical surfaces, work from the bottom up.
- Exercise caution when working on wet surfaces, as they tend to be extremely slippery.
Application
- Prevent contact with eyes, skin and clothing. Wear impervious chemical-resistant rubber gloves and safety goggles during use.
- Add full contents of 32 fl. oz container to three quarts of tap water in a plastic bucket or plastic watering can. Do not use a metal container. Stir contents using a paint stir stick. Do not apply through any type of spray equipment. NOTE: To clean stubborn stains, increase strength by adding the full contents of this container to 1 quart tap water.
- Apply Thompson's® WaterSeal® Wood Stripper liberally with a paint pad, synthetic, deck brush, roller or pour liberally from a plastic watering can. Do not apply to an area larger than you can work on within 10-15 minutes. Immediately and thoroughly rinse with water any accidental spills or surfaces that unintentionally come in contact with product.
- Allow Thompson's® WaterSeal® Wood Stripper to remain on wood for 15 minutes. Do not let Thompson's® WaterSeal® Wood Stripper to completely dry during application. Continue maintaining a wet surface by reapplying more product as needed. Immediately prior to scrubbing, lightly wet the surface with tap water. Scrub surface with a stiff, synthetic deck brush.
- If stubborn areas remain, repeat the application in those areas.
- 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. Use a wood brightener such as Thompson's® WaterSeal® Wood Brightener to neutralize the surface, allowing for the best performance of your reapplied waterproofer or stain. A wood brightener also helps restore the natural color and beauty of Redwood, Cedar, Hardwoods and other highly resinous woods.
Drying
- Wait 2-3 days, depending on weather conditions, for the wood to dry thoroughly before applying a Thompson's® WaterSeal® waterproofer or stain. Use Thompson's® WaterSeal® waterproofers and stains to protect your wood from the elements and provide the highest level of waterproofing protection available.
Clean Up
- Rinse equipment and brushes thoroughly with soap and water.
