Wood Preservatives

Extend the life of your wood with our selection of preservatives.

Borate treatments protect logs and timbers against rot, mold and wood-boring insects. They work best on bare wood, before a finish goes on, so new construction and a full refinish are the two natural moments to use them.

Log ends and checks hold water longer than anywhere else on the wall, which makes them worth treating and sealing even when the rest of the home looks fine.

The seasonal walk-around in How to inspect your log home's finish covers where to look and what to check.

Borate Treatment for Log Homes explains what borate protects against, when to apply it and how long to wait before the finish goes on. If the problem is carpenter bees, start with Carpenter Bees and Log Homes: borate is not the answer there, and the guide says what is.
