When to Apply

You know it’s time to waterproof your wood when:

• After rain the water is soaking into the wood instead of running off.
• Your wood is warping, cracking or splitting.
• Your pressure treated wood is at least 6 months old.
• Your wood has been cleaned and is completely dry (We recommend All Wood Cleaner for proper deep cleaning).
• There is no other waterproofing product on the wood.
• The air temperature is above 35 °F (2 °C).

If your wood has deep stains or mold, we recommend pressure washing with a wood cleaner and brightener before you apply Seal-Once Marine.

Mixing in The Tint

Seal-Once Marine in Natural, Bronze Cedar, & Coastal Gray tints comes premixed in the container. All other tints come in a separate bottle, and you combine them when ready to use.

When you receive your Seal-Once Marine, it will come as a clear base. If you ordered a tint, it will come in a small bottle. Each tint bottle is enough tint for 1 gallon of clear base.

• If you have a 1 gallon of clear base, mix in 1 bottle of tint.
• If you have a 5 gallon of clear base, mix in 5 bottles of tint.

Mix or shake thoroughly before you begin, and frequently throughout the application. This ensures a uniform color.

Applying Seal-Once Marine

Tools: You can use a bristle brush, air assisted or airless sprayer (use tip size between 0.017″ – 0.019″)

If possible, apply Seal-Once Marine in the shade for the best results. If applying in the sun is unavoidable, lightly mist the wood, and immediately apply Seal-Once Marine. Do not apply if it is going to rain that day.

1. Apply at least two coats of Seal-Once Marine. Keep applying the first coat until the wood will not absorb anymore.
2. Start the second coat as soon as the first is damp, but not wet. Older wood will need more applications
3. Keep applying coats until all holes and cracks have been filled.
4. If using a sprayer, apply Seal-Once Marine in a medium or coarse spray pattern, and use a bristle brush to remove any puddles.
5. Cover the entire surface and ends of the wood.

Dry Time for Seal-Once Marine

• The temperature and sun exposure affect drying time. Expect Seal-Once Marine to be dry enough to walk on in 2-3 hours.
• After 24 hours, you can apply paint or stain.

How to Clean Up Seal-Once Marine

Clean up is simple with Seal-One Marine. Clean all equipment and brushes with warm water and soap. Seal up any remaining Seal-Once Marine, and store in a place that will not freeze. Seal-Once Marine has an indefinite shelf life.

Ongoing Maintenance of Wood with Seal-Once Marine

A dock in Portland, ME that was treated seven years ago with Seal-Once Marine Cape Cod Gray, and has just been retreated.

You know it’s time to reapply Seal-Once Marine when:

• Water on the wood soaking into the wood fibers instead of running off.
• Color (tint) is fading.
• There is surface damage that exposes bare wood.
• High traffic areas have worn away Seal-Once Marine
• Any time the wood looks noticeably different.

You can apply Seal-Once Marine as often as you’d like. But before you do, you must clean the wood to ensure the next coat will penetrate into the wood, as well as remove mold, mildew, stains, and grime. Do not use corrosives, oxidizers, or any strippers to clean your wood. We recommended using only the following cleaning solution:

1. 1 gallon of warm water
2. 14 ounces of household bleach
3. 1 ounce of Dawn® Dish Detergent

Apply your cleaning solution with a sprayer and allow the solution to rest on the wood for 20-30 minutes. Then, thoroughly rinse of the wood with a garden hose.

Once your surface is clean and dry, reapply Seal-Once Marine following the Application instructions above. If apply Seal-Once Marine to only a small area, make sure to slightly overlap the new coat with the old, to ensure a uniform look.

About Waterproofing Pressure Treated Wood

When should I apply Seal-Once Marine to new Pressure-Treated Lumber?

There is some disagreement about when to apply a waterproofer to pressure-treated wood.
Pressure-treated lumber is treated with chemicals during the manufacturing process, to prolong its life and reduce maintenance. In addition, pressure-treated wood is well, “pressure treated”, which causes it to become more dense than regular wood. These two modifications to the wood means it is not ready for any waterproofing for some time, and there are several other factors that affect the wood as well.

The short answer is, do a water test: spill a small amount of water on the wood. If it runs off right away, keep waiting. But if the water absorbs into the wood or puddles up, it’s time to add a waterproofer.
