How Many Square Feet Does a Gallon of Deck Sealer Cover? (What You Need To Know)

When sealing your deck, it’s important to know how much you’re going to need. The most common question is how many square feet a gallon of deck sealer covers.

In this blog post, we will go over the answer to that question as well as some tips on how to seal your deck properly.

Answer To The Question How Many Square Feet Does a Gallon Of Deck Sealer Cover:

It depends on the product, but generally, one gallon will cover from 100 to 300 square feet.

When calculating how much deck sealer you need, it’s important to keep in mind that you’ll need to apply two coats for full protection. A gallon should be enough for the first coat, but you’ll probably need more than one gallon for the second coat. If you have a particularly large deck, it might be a good idea to buy an extra gallon or two just in case.

For example, if you’re covering a 500 square foot deck, you should get four gallons of sealer. That will give you two coats.

Tips On How To Seal Your Deck:

1. Start by cleaning the deck surface thoroughly. This is one of the most important steps, and all dirt and debris must be removed before sealing. Use a broom or a pressure washer to clean the surface, and make sure to get in all the nooks and crannies.

2. Sand the deck surface if it’s rough. A rough surface will not absorb sealer evenly, so it’s important to smooth it out before applying the sealant. Use medium or fine-grit sandpaper, and be careful not to sand too deep.

3. Apply the sealant in even strokes, making sure to cover the entire surface. If you miss a spot, don’t worry – just go back and fill it in.

4. Let the sealant dry for at least 24 hours before walking on it. And be patient – it can take a few days for the sealant to fully cure.

Following these tips will help you seal your deck properly and ensure that it lasts for years to come. For more information, be sure to check out our video on how to seal a deck.
