19 Best Rated Water Sealer For Decks 2022

There are two kinds of deck sealing: liquid and powder. Both types serve the same purpose: preventing rain, snow, and other liquids from penetrating the wood. The only difference between the two is that with liquid sealers, you pour the solution onto the deck and spread it with a brush. With powder, you apply the product to the deck, let it dry, and then wipe off any residue with a rag or cloth. Both types have pros and cons.

If you’re the DIY type, then liquid is the best option. It’s less messy and easier to apply than powder, and it dries quickly. But it also requires some investment. The solution (usually made up of water, mildewcide, and/or preservatives) is costly to buy, and since you have to pour it onto the deck, you have to have a big enough container or pitcher to do the job. For multiple coats, you'll need to buy one of the large bottles. That being said, if you want a quick-and-easy DIY solution, then you’ll need to go for the powder. It’s just as fast and easy as the liquid, but doesn’t require as much prep work.
