Preparation and Application
Sand the wooden post to expose the natural timber. Wood posts can be pretreated or varnished. By sanding the wood, the waterproof sealant absorbs directly into the wood posts.
Dust the debris from the wood post using a rag. Leftover debris blocks the waterproof wood sealant from absorbing into the wood post.
Pour 8 ounces of waterproof wood sealant into a paint tray.
Apply the waterproof sealant to the brush. Brush a thin layer of waterproof sealant over the entire wood post.
Let the waterproof sealant dry for 12 hours.
Repeat Steps 3 to 5. To effectively waterproof a wood post, three coats of waterproof sealant are needed.
