Decks are the centerpiece of many yards. They make a house look good and also serve as a great place to hang out or host parties. However, as they sit outside, they also take a lot of abuse over the years.
As a result, you want to protect that. There are a few options here and there, but one of the best ways is a deck sealer.
Sealers are special substances that, like deck stains, protect your deck from the elements. However, not all of them work with the same efficiency.
While you’re going to get good performance from many sealers, some of them will last much, much longer than others.
This guide will cover some of the longest-lasting options out there.

When looking at the best deck sealers there are a few key characteristics you need to keep in mind. They all matter, but none are more important than where your deck is situated.
That knowledge is key because it will tell you how exposed your deck is as well as how much sun it gets.Though the following sealers all work for extended periods of time across all decks, there are a few key differences to be aware of.
For instance, oil-based sealers are better for decks that get a lot of sun because of how deep they penetrate. In contrast, wood sealers are much more effective at stopping moisture, which helps your deck keep its shape and color.
Knowing the difference will enable you to find the best deck sealer for your home.
