Chinking & Sealants

Log Home Sealants

All of our log home caulking and chinking products are formulated with premium acrylic latex. These log home sealants are stable through freeze thaw cycles, resistant to chemicals, salt spray, water vapor and mildew, are suitable for both interior and exterior use, and will accept any stain we sell.

Synthetic chinking will seal wide gaps in traditional log homes, and simulates classic chinking.

Textured caulking is ideal for sealing narrow gaps and blends in with the surrounding wood.

Smooth caulking is designed to seal between courses of milled log home logs.

    Big Stretch

    Homes move. Window frames pull away from the siding or doors shift against the brick. They move when the temperature changes, the rain falls, the wind blows or the earth quakes. Most caulks can’t take it – they dry hard and crack. That’s why you need Big Stretch® high performance water-based sealant.  Its powerful adhesion and extreme elasticity will stick, twist, bend, compress, and stretch – more than 500% of original size! – to handle most any movement your home can dish out, all without cracking.

    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 For Wood. 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.
