Product Overview

Easy to use – Hard to See – Textured Caulk for Wood

You want to see your logs, not shiny caulk lines, but caulk is necessary to keep the weather and bugs out. You need Conceal®. Conceal® is the first caulk designed specifically for wood. Its lightly textured to simulate the natural roughness of wood and extremely elastic to maintain a years-long seal that keeps weather, bugs, and moisture out. Available in seven colors designed to complement the most popular wood stain colors, Conceal® disappears into the woodwork so you don’t know where the wood starts and the caulk begins.


Online Review

I used this caulk to fill gaps between logs in my log home (on the inside). It really does blend in well once dry, you’d hardly know it was there. And a home energy test done on my home after the fact showed that it reduced airflow quite a bit, which should help save on energy bills.
