How to Apply Deck Sealer
There are different techniques you can use to apply deck sealer. Applying a sealer with a brush will give you the greatest control and an even application. This will also help you make sure the sealer not only gets on all the boards, but also in between the boards as well. The downside of applying deck sealer with a brush is it takes more time.
You can roll sealant on with a paint roller. This is a much faster process but you won’t have as much control. You may need to go over it a few times to make sure that everything is properly coated.
You can use a garden sprayer to apply sealant. This is the quickest way to get the sealant on the deck. However, it offers the least control, especially in hard-to-reach areas. If you choose this method, you need to be careful to cover nearby plants to protect them from getting sprayed with sealant.
