When Seal-Once Marine cures, it creates a dense but transparent film, preventing moisture from coming in contact with the wood.

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

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.
