Before you begin

  • This product is corrosive. Handle with care.
  • Thompson's® WaterSeal® Maximum Strength Deck 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® Maximum Strength Deck 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® Maximum Strength Deck Stripper to come into prolonged contact with carpet or fabric, as damage may occur.
  • After application of Thompson's® WaterSeal® Maximum Strength Deck Stripper, it is strongly recommended you use a wood brightener such as Thompson's® WaterSeal® Deck Cleaner & Brightener to neutralize the surface and allow for the best performance of your reapplied waterproofer or stain. Thompson's® WaterSeal® Maximum Strength Deck Stripper may substantially darken Cedar and Redwood. 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 contents of container to a plastic bucket or plastic watering can. Do not use a metal container. Do not apply through any type of spray equipment. Contact with spray mist causes eye, skin and respiratory tract burns.
  • Apply Thompson's® WaterSeal® Maximum Strength Deck Stripper liberally with a synthetic bristle brush or 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.
  • Wait 10-15 minutes and then scrub the surface with a synthetic, stiff bristle brush (do not use a wire or natural bristle brush) to remove any stain or finish that does not immediately come up. Do not let Thompson's® WaterSeal® Maximum Strength Deck Stripper completely dry during application. If it does dry, re-wet surface with product.
  • 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® Deck Cleaner & 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 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.

Clean Up

  • Rinse equipment and brushes thoroughly with soap and water.
