What is the Best Deck Sealer in 2024?

What is the Best Deck Sealer for my exterior wood? This is a popular question I receive on DeckStainHelp.com. Deck Sealers typically come in two different types: a clear sealer and a lightly pigmented Transparent Deck Sealer. Both types are penetrating and will thoroughly soak into the wood.

In this article about the Best Deck Sealers, I will explain the major differences between the two types and offer our advice on which brand is best for each.

Best Deck Sealer


Best Clear Deck Sealer

Clear deck sealers are not the same as deck stains. A true deck sealer is clear with no color. They are used to protect the wood by weatherproofing it from water. They will offer little to no UV protection, as the tint or color of a deck stain is your UV protection from graying. They have limited protection from mildew and mold. They will need to be reapplied every 3-12 months.

Cons: It must be reapplied every 12 months, much longer than other clear sealers.

Best Transparent Deck Sealer

Lightly tinted transparent deck sealers have close to 30-40% solid content. They offer a minimal amount of color enhancement to the deck. They have moderately low UV protection from graying and will repel water for a period of time. Typically, they need to be reapplied every 9-18 months.

Armstrong Clark Transparent Stain

Armstrong Clark Wood Stain RatingMy Best Transparent Wood Deck Sealer

Where To Find: Armstrong Clark Transparent Sealer
Pros: It is easy to apply and enhances the natural grain of the wood. Armstrong Clark is one of our top three brands of deck stains and sealers for our customers’ decks in the Midwest. It is very easy to reapply as needed. Just clean, let dry, and apply another coat.
Cons: Moderate mildew protection for wet climates. Typically, this is not an issue, but we have seen a few cases.

My new pressure-treated deck is now one year old and I need to find the best product stain to apply to inhibit black mold for the longest period of time possible. The deck is practically in all shade all day and is already developing black mold spores. My last deck had to be power washed constantly and stain reapplied Every few years, ridiculous! Isn’t there a better product out yet that inhibits the growth of mold for a longer period of time?

Just had our deck stained with Defy semi transparent stain in Walnut. But now 3 months later, the water is not beading up like it did when first done. Anything I can do to remedy this ?

HI, I just stained a newish pressure treated softwood deck (I now know I should have waited…) and would like to seal it over the stain – what should I use? My other question is similar – I have rough oak planters I tinted with 3 to 1 water/stain mix and I’d like to seal them too but have no idea what to use. I would need something completely clear so as not to alter the existing tone of the deck and planters. Any advice would be so appreciated – thanks.

I put a transparent deck sealer over my new deck (pine) after cleaning it with pressure washer. It now completely repeals the water but retains any dirt, even after using hose to spray off. What have I done wrong?

We stained our deck with grey Cabot stain and sealer 3 months ago on a new deck that had aged over the winter. We applied one coat and let it dry only 3 hrs. The deck is already full of brown spots from dog paw prints…..
We are going to power wash and restain the deck using the same product. Is this the right thing to do?
If we let it dry longer, will we be able to wash off the dog paws prints in the future
