Protect Exposed Wood with Epoxy Sealer
Friday, July 25th, 2008|
If you have windows or other woodwork that get exposed to a lot of moisture, you may want to take a closer look at a product called Clear Penetrating Epoxy Sealer. When brushed onto bare wood, this product actually penetrates into the wood fibers to protect them from moisture damage. Like standard epoxy, this epoxy sealer is a two-part product that gets mixed together before use. But what’s different about this sealer is that it’s a blend of epoxy and a solvent, so it’s as thin as water (Photos, below). This thin consistency is what allows it to soak into the wood (Photo, top right). The sealer also creates a compatible surface for paint or varnish to form a strong bond with.
You can use epoxy sealer on bare wood. But if the wood has mold or mildew damage, you’ll need to do some prep work first. Start by stripping the old finish and sanding the surface smooth. Neutralize any damage with bleach (Fig. 1). Then, brush on the epoxy sealer (Fig. 2). Once the sealer dries, sand the wood lightly, and apply a protective varnish (Fig. 3).

Unlike standard epoxy (left), this epoxy sealer penetrates into the wood and solidifies the structure of the wood fibers (right). This helps protect the wood from moisture damage. |
1] To fix damaged wood, strip the existing finish. Then scrub any dark areas with a 50/50 solution of bleach and water.
2] After mixing the two-part epoxy sealer, brush it liberally onto the wood. Keep brushing until the wood is saturated.
3] Let the sealer dry overnight, sand lightly with 220-grit sandpaper, and then apply three coats of varnish or paint. |
