Looking to put the final touches on your deck but can’t figure out what sealer/stain to purchase? Don’t worry; you’re not alone!
A deck sealer is an important part of your porch’s aesthetic appeal, durability, and environmental resistance. It is crucial to have your deck sealed to prevent the decomposition of wood, mold accumulation, and heat/moisture damage.
There are many types of deck sealers on the market, however, and the correct choice for your porch may be unclear. It’s difficult to narrow the choices down, due to the vast amount of wood used in today’s porches.
Things to Consider
Let’s have a look at some things to keep a note of when looking for the best deck sealer for your porch.
- The Climate in Your Area. The deck sealer you purchase will be based on a variety of considerations. One of these considerations is the weather and climate of your area. Deck sealers are designed for specific climates; many are engineered for specific temperatures and humidity levels.
- Opaque or No? The more opaque a deck sealer is, the more resistant the sealer is to harsh weather. You’ll want to keep your eye on this feature and have in mind what type of elements your deck will be exposed to on a routine basis.
- Natural or Synthetic Wood. One sealer does not work on all types of decking material. Synthetic deck sealers are different from natural wood deck sealers, so make sure you double-check this before you purchase.

Let’s take a look at some more details regarding the best deck sealer for the type of wood that’s present on your porch.
- Type of Wood. Deck sealers can often handle different types of wood. Sometimes, however, certain types of wood won’t stain properly with certain types of sealer. You’ll want to keep a note of the type of wood you’re looking to seal and make sure the sealer you purchase can work on the wood!
- Clear Sealer. A clear deck seal functions to preserve the natural beauty of your wood. While these sealers can be perfect for environments that aren’t subject to harsh weather, they can also be easily undone if they’re consistently exposed to harsh weather such as heavy humidity and rain.
- Quantity per Square Foot. Take measurements of your deck before you shop for a deck sealer. You’ll want to make sure the amount you buy is suitable for the surface area of the deck you’ll be sealing!

Frequently Asked Questions
Is it Better to Stain or Seal a Deck?
To maintain the color of your deck, you seal it. However, if you want a more uniform color, you stain the deck. A wood stain is more expensive than a sealer but it lasts 5 times longer.
How Long Does Deck Sealer Last?
To properly maintain your deck with a protective finish, you need to diligently apply a new protective coating every one or two years.
If your deck has been neglected or is showing signs of wear, it may not be time to replace it, but to restore it with a new layer of finish. When evaluating your wood deck, don’t limit yourself to the surface alone but look at all areas to determine if restoration or replacement is your best option.
Restoring your deck can extend its useful life for another 10 years or more. Decks are most likely to be taken out of service due to rot, termites and nails pulled from sagging boards — not because they cannot withstand the weather.
How Long Does a Deck Need to Dry Before Sealing?
The time for allowing the deck stain to dry should be long enough for the moisture level in it to drop below the point where it lifts off again. If your deck is exposed to a lot of wind, or if you have created some local “pockets” with uneven stain coatings, allow an extra day.
The best test before applying the sealer is to lift any loose end of the tape and apply a little pressure with your fingertip. If it “pops” free easily then you are ready for the sealer.
Sealing wood decks after staining can increase their durability and beauty and help prevent mold or mildew. Most stains for use on exterior wood surfaces should be allowed to dry for at least two days before applying a sealer.
Deciding on which sealer and stain to use for your deck can be a difficult process. With so many options available, it’s hard to determine what product is best for you.
There are different features and benefits you should consider when making your decision. That’s why it’s important to practice proper research when it comes to this topic. The good news is that you’ve come to the right place.
