Can Deck Sealer Be Sprayed On?


As one of the parts of your home most exposed to the elements, your wood deck or patio needs to be properly protected. Some types of woods may be more resistant to water and insect damage over the years, but all wood decks will eventually suffer the same issues due to weathering, including rot and decay. However, there are some simple ways homeowners can prevent or drastically delay this wood rot and decay. One of the best ways to protect your deck is to regularly seal the wood.
 

Why is it important to seal your deck?


An outdoor deck is much more exposed than the interior wood on your log home, or your indoor wood furniture. Think about the amount of rain, snow and sun your deck takes each year. Add on insects and animals, and those outdoor wood decks really need to be tough! Properly sealing your deck helps protect the wood from sun damage, water weathering and insects, as well as the general wear-and-tear of people walking around and moving furniture across it. Wood decks and patios are a great investment and add a lot to a home; you want to protect yours as long as possible.
 

Methods for Sealing Your Deck


There are a few ways that you can apply sealer to your deck. Each has its merits and negative aspects, so it can be good to use a combination of methods to ensure your entire deck is coated and protected.

Paint Brush


One way to apply sealer to your deck is by hand with a paint brush. This might be the easiest way for a small deck or stoop, or if your deck has a lot of details and hard-to-reach places. Applying sealer by hand can be the most time consuming, but it is the easiest way to ensure you get all the cracks and more difficult to reach places, such as corners and between boards.

Roller Brush


A roller brush is a slightly faster way to seal your deck. Much like when you paint a wall with a roller brush, you can cover more ground quicker than with a paint brush. However, a roller brush cannot get in those hard-to-reach places, such as between boards, due to its size and maneuverability. If you have a large area to cover, a roller brush can also be time consuming. These are best for medium sized decks.

Sprayer


One of the fastest ways to apply sealer is with a sprayer. This can be done with an ordinary garden sprayer, so long as it has been well-cleaned before you use it. This is also one of the easiest ways to seal a deck, as there is very little mess. However, this offers less control for application in the hard-to-reach places. See our tips below on the best way to use a sprayer to seal your deck.

A Guide to Spraying Sealer on Your Deck


Using a sprayer to seal your deck can be quick and easy. Here’s how:
 
  1. Clean the surface of the deck to start. Using a stiff broom, sweep the deck. Then use a water-and-soap solution to clean the surface. Do not allow the liquid to soak into the surface of the wood, but use the broom to sweep it across the surface. This should remove dirt and debris from the deck.
  2. Spray the deck with a power washer after you sweep it at a mid-level pressure. Pay special attention to cracks and edges. Keep the nozzle at a mid-range fan and at least a few feet away from the surface to avoid damaging the wood. Allow the deck to completely dry for 48 to 72 hours.
  3. Cover the side of your home with plastic sheeting, held in place with masking tape.
  4. Set up the sprayer and, if applicable, turn on the air compressor, set at at least 50 pounds-per-square-inch. As you spray, hold the nozzle at least 12 inches away from the surface.


Spray the deck, working with the grain of the wood down the length of the boards. Move row by row, starting from the side of the home out to the edge of the deck, then moving down the stairs (if applicable.) Avoid overspraying rows.


  1. Spray the exterior edges, banisters and railings last.
  2. Allow the deck to dry for up to 72 hours before removing protective layers surrounding the deck or using the surface. 


Tips for spraying sealer on your deck.


  1. Cover any nearby foliage, walkways or furniture with plastic or other coverings to ensure they stay sealer-free.
  2. Pick a week with sunny days and no wind in the forecast so it is less likely that leaves or other debris will blow onto your deck or stick to the surface as it dries.
  3. Always spray a small test area in a spot that is low-traffic or out of the way to ensure your sprayer and sealer is set up correctly.
