Easy to Use – Hard to See
Keep out weather, bugs, and moisture without seeing it. Conceal disappears into the woodwork so you don’t know the wood starts and the caulk begins.
Interior & exterior wood surfaces or where a textured wood sealant look is desired, including: * Log homes * Log checks and cracks * Wood siding butt joints * Around wood doors and windows * Where wood meets chimneys * Corner boards * Baseboards * Crown molding * And more! Adheres well to most standard building materials.

Common Questions From Our Network of Pros
Conceal is lightly textured to blend in with woodgrain. It’s also available in 7 different colors that closely match the most popular stain colors. Because of the texture, it’s not quite as shiny as Log Builder. Log Builder is a traditional smooth acrylic sealant and is available in 3 wood-toned colors. It will depend on the look you want which product you use, but we can guarantee you excellent results, no matter which direction you go.
One the first go around, we recommend caulking very last, for a few reasons: 1) the stain acts as a “primer” for Conceal, helping it to adhere to the joint better; 2) the stain provides an added barrier of protection behind the caulk, in case the crack or check opens up wide over time (which is part of the normal charm of a log homes); and 3) it’s best to match the caulk to the stain the first time around. When it’s time to do maintenance coats of stain, you can certainly apply the stain over top and it won’t cause any issues and will be a close match most of the time.
