Directions

Before You Begin

• Do a trial test before application. Surface may darken slightly with application and color appearance is different when fully dry. Also, previous water repellent treatments may interfere with the penetration of this product. If your deck has been routinely treated with a water-repellent, substantial cleaning may be required. To test, clean deck and apply product by brush to a one sq. ft. area that has experienced either low traffic, rests under an eave, or is in a corner. Product should penetrate wood if surface is properly cleaned.
• Do not apply if rain is expected within 48 hours. Also, temperature must be above 50° F and remain above freezing for 24 hours.
• Cover plants and shrubs. If using a sprayer, move all objects that could come in contact with over-spray. Wet over-spray can be removed by flushing immediately with water. Dry over-spray can be removed with mineral spirits.
• Do not use in below grade application where water pressure is a problem or on painted or recently stained surfaces.
• DO NOT USE AS AN ADDITIVE TO PAINT.
• Protect product from freezing. Do not store below 32° F. in case of accidental freezing, call The Thompson's Help Line at 1-800-367-6297.

Surface Preparation

• Wood surface must be free of all dirt mildew, mold, waterproofers, wood stains, paint and other contaminants. Prior to application, clean surface completely with a wood cleaner and/or pressure-washer depending on condition of deck and level of cleaning needed. See chart below to select the right cleaning product.

Cleaning Products

• Redwood & Cedar Cleaning Instructions: These woods have natural characteristics that require special treatment to enhance beauty and waterproofing performance. When cleaning, we recommend using a pressure-washer (water only) at 1200 psi. If a pressure-washer is not available, Redwood and Cedar may need a Brightener to neutralize wood and restore its color after using a wash, cleaner, remover, or stripper. Wait 48 hours after application of the Brightener to apply this product.
• Power Washer: A power washer is a useful tool particularly in combination with a stronger cleaner when removing film-forming finishes or stains.
• Thoroughly rinse surface and remove all excess water. After cleaning, wait at least 2 hours before applying product. Allow longer drying time (4 hours) on overcast or cooler days below 60° F. It is not necessary for the surface to dry completely before application of this product.

Application

• Do not use with other waterproofing products, as variations in the final appearance of the wood may result.
• Do not thin.
• Can be applied immediately to new pressure-treated wood.
• Can be applied to damp, freshly cleaned wood.
• Shake or stir contents for a minimum of 2 minutes before use. Intermix all containers (of the same color) to be used to assure color uniformity.
• A small trial patch should be tried before application over the entire surface.
• Apply using a paint pad or brush. If using a garden or pump-up sprayer, back-brushing (with a paint pad or brush) will be required to even out the finish. DO NOT APPLY USING A ROLLER. Some nozzle openings of sprayers may be too small for this formula. DO NOT THIN. If clogging occurs, use paint pad or brush.
• Apply only ONE THIN even coat. A heavier, or additional coat will NOT improve performance or appearance. DO NOT APPLY TWO COATS. Avoid puddling.
• Tackiness will result if over applied. May also occur after application if overnight temperature falls below 50° F within 48 hours of application.

Drying

• Drying time will vary depending on wood surface and humidity. Allow a minimum of 12 hours before using the deck.

Clean Up

• Clean brushes and equipment with soap and water. Dry product can be removed with mineral spirits.
