Before You Begin

  • This product contains bleach. Handle with care.
  • A trial patch is recommended before starting. If the surface has been previously treated with a waterproofer, splash the surface with a glass of water. If it beads, dampen the wood slightly before using Thompson's® WaterSeal® Deck Wash.
  • Remove all deck furniture and decorative items. Do not allow product to come in contact with painted or finished surfaces that you do not intend to restore.
  • Saturate the ground around plants and shrubs with fresh water prior to application. Then cover all plants and shrubs to protect them from overspray. Uncover promptly after use.
  • Wear protective gloves and old clothing. Do not allow product to come into contact with clothing, carpet or fabric, as discoloration can occur. When spraying, use eye protection.
  • The longer Thompson's® WaterSeal® Deck Wash is allowed to work, the lighter the wood will become. Do not allow the product to remain on the surface for more than 30 minutes, as an uneven appearance may result.
  • Thompson's® WaterSeal® Deck Wash may slightly darken redwood or cedar. To brighten wood after cleaning with this product, use Thompson's® WaterSeal® Deck Cleaner & Brightener.
  • Plan the application: for horizontal surfaces, work backwards so that you do not walk on the surface being treated. For vertical surfaces, work from the bottom up.
  • Exercise caution when working on wet surfaces.
  • Thompson’s® WaterSeal® Deck Wash can also be used on exterior painted surfaces to remove stains from mildew if diluted 50/50 with water.
