DeckWise® WiseCoat®

Premium Hardwood Deck, Siding & Fence Sealer


All wood surfaces should be cleaned before sealing with DeckWise® WiseCoat® Premium Hardwood Deck, Siding & Fence Sealer for best penetration and performance. Clean all dirt, dust, loose material, and debris. Remove any oil, grease, grime, algae, mill glaze and mildew and mold stains with appropriate cleaners. DeckWise® Deck & Wood Cleaner Part 1 and Brightener Part 2 are recommended.

After cleaning the wood, always test the absorbency properties of the wood. Sprinkle a few drops of water on the wood’s surface, if water droplets do not penetrate, there could be an old finish still present. Stripping could be a necessary step to remove old finishes and coatings prior to applying WiseCoat®. After any stripping, retest the wood’s surface absorbency when dry.


  • Do not apply if surface or air temperature is below 45°F/7.22°C.
  • Do not use or apply in rain or when rain is pending.
  • Do not thin WiseCoat®. Always mix well before using. Shake canister contents or stir thoroughly prior to application.
  • Apply two coats; wet over damp with an air-assisted and/or airless sprayer, a pump-up garden sprayer, brush, or stain pad. Back brush out any puddles. (Use a 17-19 tip with a medium to coarse spray pattern.)
  • For best results, apply out of direct sunlight and in shade. NOTE: When applying in direct sunlight, the wood surface will be hot. It is best to spray the surface with a mist of water, and then apply WiseCoat® immediately onto the dampened wood surface.
  • Apply to all wood surfaces.
  • Apply WiseCoat® End Grain Sealant to wood ends
  • Do not apply with other wood waterproofing products.


Approximate coverage: 250-350 sq. ft./gallon per coat. Actual coverage may vary due to porosity of surface.

Drying Time

Allow roughly 2-3 hours to dry depending on ambient temperature and humidity before exposing wood surface to light foot traffic. Climate conditions will vary.

Allow 12-24 hours to pass for a full cure, depending on ambient humidity and temperature.

Whenever re-coating, apply WiseCoat® as soon as previous coat has penetrated and the surface is still damp, but not wet. Back brush any pooling.

Clean Up

  • Sprayer equipment and brushes clean up easily with warm soapy water.
  • To protect from freezing, store above 32°F/0°C.
  • Shelf life approximately 3 years.
  • Disposal: typical soap and water cleanup with no special disposal procedure required.

Safety Precautions

  • Clean areas of over spray with garden hose water. Avoid over spray of tinted formula on plastic materials. Clean with water immediately.
  • Avoid inhalation of spray. If breathed in, move to an area with fresh air.
  • Avoid contact with eyes. If sealer is splashed into eyes, immediately rinse with clean water for 15 minutes.
  • For skin irritation, wash the area with soap and water thoroughly.
  • If accidentally ingested, immediately drink 2 glasses of water and contact a physician. Do not induce vomiting.

Note: Ipe, Tigerwood, Massaranduba, Redwood, Cedar, Mahogany, Douglas Fir, etc., contain tannic acids that tend to migrate to the surface of the wood and may cause discoloring. These tannin stains may be especially noticeable on light colored wood. This discoloration is not harmful and can easily be removed with DeckWise® Cleaner Part 1 as a yearly maintenance procedure prior to applying a fresh coat of WiseCoat®. Thoroughly rinse and do not allow cleaning solution to dry on wood surface.

Performance Guarantee and Limited Liability

Limited Liability: This product, DeckWise® WiseCoat® is guaranteed to prevent excessive water accumulation below the wood surface for six (6) years on horizontal surfaces and ten (10) years on vertical surfaces, when used according to the product instructions.

WiseCoat® contains a semi-transparent tint which helps to enhance and preserve the natural beauty of the wood including protection from harmful UV rays. The additional UV blockers present in our tint help prevent wood graying as the nano-sized pigment particles penetrate the wood surface for a durable color.

Manufacturer’s responsibility is limited to the purchase price of this product. Keep out of reach of children.

NOTE: There is no warranty against color fading, whether expressed or implied. In order to maintain color, it is advised to do so with a yearly maintenance plan.   Depending on regional climate conditions, additional coats may be applied to restore the preferred natural wood tint color. 


Clean and brighten hardwoods at least once a year with DeckWise® Deck & Wood Cleaner Part 1 and DeckWise® Deck & Wood Brightener Part 2 or  use the DeckWise® Deck Restoration Kit with all the products and tools needed in one handy package. Apply WiseCoat® on decking and hardwoods every one  to two years in most applications for desired natural hardwood color.

Maintaining a clean deck or hardwood surface between finish applications is recommended with the use of a mild detergent using a soft bristle brush, and warm water. Mix the mild detergent in a bucket of warm water; gently scrub the wood surface with the mixture. Allow the mixture to rest on the surface for roughly 5 minutes, and then thoroughly rinse the wood surface with water.
