Summer and spring are the best times of the year to enjoy your beautiful wooden deck. All those priceless hours of entertaining, barbecuing with family and friends, are memories that will last a lifetime. But your deck won’t last as long if you don’t take necessary care of it.

When the fall and winter months come around, your deck may suffer from serious damage especially if you haven’t waterproofed it. Without waterproofing, your deck won’t be as beautiful or functional when the next summer rolls around.

If you ignore the importance of waterproofing, this could lead to a complete restoration of your deck, which is by no means cheap.

How To Use

Before you begin your DIY waterproofing project, it’s important to make sure that newly pressure-treated wood waits 30 days before application. Air and surface temperatures should be at least 50F during the application, and at least 48 hours after.

Do a splash test first by sprinkling some water on parts of the surface that will be treated. If you notice that water is absorbed and ends up darkening the surface color within 5 seconds, this means that the surface is porous and ready for treatment. But if water beads up or sits on the surface, it doesn’t require treating just yet. 

Make sure that shrubs, plants, and other objects that will not be treated are protected from overspray. Don’t mix Thompsons Waterseal Wood Protector with other waterproofing products; do not thin either.

Shake the container well before use, and mix occasionally during use.

  1. 1
    Use a roller, sprayer, or brush for application. If you have applied too much, wipe the excess or distribute it to other parts of the surface.
  2. 2
    Apply with proper ventilation.
  3. 3
    One coat is all you need for most cases.
  4. 4
    Allow the surface area to dry for at least 48 hours, though drying time may vary depending on the temperature, substrate, and humidity.

Then, it’s time to clean up by following the manufacturer’s recommendations. That’s it! It’s so easy to protect your wooden deck with this sealer.
