Best Deck Sealer for Old Decks: Bring Your Deck Back to Life

If you have an old deck that’s starting to look worn out, the right deck sealer or stain can give it a fresh look and help protect it from the elements. Choosing the best deck sealer for old decks isn’t always easy, though – there are many products out there, and each one has different benefits. 

In this guide, we’ll cover some popular options, explain the types of deck sealers and stains, and provide recommendations to help you make the best choice for your old deck.

Why Seal or Stain an Old Deck?

Over time, wood decks can start to show wear and tear, especially if they’re exposed to sun, rain, and fluctuating temperatures. This can cause the wood to fade, crack, or even rot. A good deck sealer or deck stain can help:

Protect the Wood: Sealing or staining forms a protective layer over the wood, helping to prevent water damage, sun fading, and general wear.

Restore the Look: A fresh coat of deck stain can bring out the natural wood grain, giving an old deck a new life.

Extend the Life of Your Deck: Using the best deck sealer or stain can help your deck last longer, saving you money in the long run.

Types of Deck Stains and Sealers

There are a few different types of deck stains and sealers to choose from. Each one works best for different situations, so knowing what each type does can help you pick the best option for your old deck.

1. Solid Deck Stain

Solid deck stains give a layer of solid color that covers the wood grain. This is a good choice if your deck has a lot of wear or uneven color since it will provide a uniform look. Solid stains also offer strong protection from UV rays, which can help prevent further fading.
  • Best For: Older, weathered decks with a lot of imperfections.
  • Pros: Strong UV protection, even color, covers imperfections.
  • Cons: Hides natural wood grain.

2. Semi-Transparent Stain

Semi-transparent stains allow some of the wood grain to show through while adding a touch of color and protection. These stains are popular for decks that are still in decent shape but need some color and UV protection. They provide a more natural look while still protecting the deck from moisture.
  • Best For: Wood decks that still have a nice wood grain.
  • Pros: Shows natural wood grain, offers good UV protection.
  • Cons: Won’t cover imperfections completely.

3. Deck Sealers

Deck sealers are clear or slightly tinted products that are used to seal the wood without adding much color. They’re perfect if you want to keep the natural color of your deck and simply want to protect it from water and sun damage. Deck sealers are typically less noticeable but don’t provide as much UV protection as stains.
  • Best For: Decks with beautiful wood grain you want to keep visible.
  • Pros: Keeps the natural look, protects from water.
  • Cons: Limited UV protection, may require frequent reapplication.

4. Semi-Solid Deck Stain

Semi-solid stains offer a balance between solid stains and semi-transparent stains. They add more color than a semi-transparent stain but still allow a bit of the wood grain to show through. This type can be good for decks that need more coverage but still want a hint of natural wood.

  • Best For: Decks that need extra coverage but still want some natural grain to show.
  • Pros: Good color, some wood grain visibility.
  • Cons: Less natural look than semi-transparent.

Tips for Sealing or Staining Your Old Deck

Clean the Deck First: Use a good deck cleaner to remove any dirt, mold, or old finish from the deck boards. This helps the stain or sealer adhere better.

Apply Evenly: Make sure to apply the deck stain or sealer evenly to get a consistent finish. Use a brush for best results.

Reapply as Needed: Some deck stains and sealers last longer than others. Keep an eye on the deck surface, and reapply when you see signs of wear.

Choosing the Best Deck Sealer for Pressure Treated Wood

Pressure treated wood decks can be a bit tricky to seal or stain. It’s important to pick a deck sealer that can penetrate the wood effectively. Look for products designed for pressure treated wood to get the best results.

Maintaining Your Old Deck After Sealing or Staining

Once you’ve sealed or stained your old deck, a little maintenance can go a long way. Sweep off debris regularly, and clean the deck surface as needed to prevent dirt and moisture buildup. This will help your deck finish last longer and keep your deck looking fresh.
