Please note: Actual coverage will vary due to porosity of the wood on which it is applied. In cases where Seal-Once Total Wood Protection Waterproofing Wood Sealer is applied to very dry, weathered or media blasted wood 3 coats may be necessary.
Seal-Once Total Wood Protection Waterproofing Wood Sealer is a minimum two coat product. Applying less than two coats will greatly affect the durability and longevity of the product.
Please Note: Woods such as redwood, red cedar, mahogany, Douglas fir, etc. contain tannic acid which tends to migrate to the surface and discolor the stain, especially noticeable when using light colors. The discoloration is not harmful and can usually be removed. Apply a cleaning solution of All Wood Cleaner. Do not allow cleaning solution to dry on wood surfaces.

Check the Moisture Content of Your Logs
Do not apply Seal-Once Total Wood Protection Waterproofing Wood Sealer to wood with over 22% moisture content.
To test the moisture content of your wood, borrow a moisture meter from your contractor or purchase one at your local hardware store. For quick reference:
Laminated logs: The moisture content of laminated logs is generally below 14%. These logs are usually ready for immediate application of Seal-Once Total Wood Protection Waterproofing Wood Sealer once they have been cleaned and allowed to dry for the appropriate amount of time. Always use a moisture meter to confirm the moisture content.
Kiln-dried or air dried logs: Use a moisture meter to check.
Green, wet, or treated logs: These logs have a moisture content greater than 22%. Allow the logs to sit in a dry area and check their moisture content on a regular basis. Logs with high moisture content can take up to 6 months to 1 year to reach the appropriate 22% or below moisture content for applying Seal-Once Total Wood Protection Waterproofing Wood Sealer.
Apply a Wood Preservative
A wood preservative (borate) is only necessary for new construction with logs, siding, and structures that are infested with powder post beetles and termites. Not needed for deck applications.
Have your logs been pre-treated with a wood preservative (borate) at the factory or mill? Contact your log or siding provider if unsure.
What is a wood preservative?
Wood preservatives (borate) make wood toxic to wood damaging organisms such as powder post beetles, carpenter ants and fungi. Wood preservatives do not protect against Carpenter Bees and other wood drilling insects, only those that ingest wood. Click here to find out about additives available for prevention of Carpenter Bees.
Why apply a wood preservative (borate) before applying Seal-Once Total Wood Protection Waterproofing Wood Sealer?
Applying a wood preservative can protect your home from damaging organisms for the life of the home. Seal-Once Total Wood Protection Waterproofing Wood Sealer soaks into wood to create a film that protects against mold/mildew growth and repels water. If a tint is chosen with Seal-Once Total Wood Protection Waterproofing Wood Sealer, the tint provides UV protection. Seal-Once Total Wood Protection Waterproofing Wood Sealer on its own is not a wood preservative. LogFinish.com recommends applying ShellGuard RTU or ShellGuard Concentrate to your logs before applying Seal-Once Total Wood Protection Waterproofing Wood Sealer.
Caulk All Gaps and Checks
Caulking is only necessary if your project contains logs and siding. Not needed for deck applications.
It is natural for wood to crack/check over time due to changing seasons, temperature and aging.
Fill any spaces between the logs and upward facing cracks/checks in the wood after applying a wood preservative and before applying Seal-Once Total Wood Protection Waterproofing Wood Sealer. Fill all joints, cracks, and nail holes with a good quality acrylic latex caulk/filler created specifically for use with wood like Energy Seal or Check Mate 2 prior to applying finish.
Test the Stain
We always recommended performing a two coat color test to a clean, dry, bare area of the structure that you are planning on applying Seal-Once Total Wood Protection Waterproofing Wood Sealer. Please Note: Seal-Once Total Wood Protection Waterproofing Wood Sealer is difficult to remove once it has been applied. Before doing a full application make sure that your color selection is correct, has a look you want, and a maintenance schedule you can manage.
