You want to see your logs, not shiny caulk lines, but caulk is necessary to keep the weather and bugs out. You need Conceal® Textured Caulk. Conceal is the first caulk designed specifically for wood. It’s lightly textured to simulate the natural roughness
of wood and extremely elastic to maintain a yearslong seal that keeps weather, bugs, and moisture out. Available in several 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.
Plus, Conceal is:
• Easy to apply and smooth out
• Easy to clean up with water
