“Designed to highlight the natural beauty of wood.”

Protects from within — CUTEK® keeps wood strong, stable, and naturally beautiful.

Protection That Starts from Within

Most wood coatings only protect the surface — CUTEK® goes deeper. Instead of forming a brittle film that eventually cracks, flakes, or peels, CUTEK® Extreme penetrates right into the core of the wood. By driving moisture out and creating a self-healing barrier from the inside, it minimizes cupping, warping, and splitting — even in the harshest climates. This unique penetrating oil technology has been proven for over 30 years, offering long-term protection and preserving the natural beauty of your wood for years to come.

Why Surface Protection Isn’t Enough

Traditional varnishes and so-called “penetrating” oils only guard the surface of the wood. Over time, exposure to sunlight, moisture, and natural movement causes these surface films to crack, flake, and peel — leaving the wood vulnerable to water damage. Once moisture seeps in, it leads to cupping, warping, splitting, and rot. Restoring that protection is costly and time-consuming, often requiring complete stripping and reapplication.

Easy Application. Effortless Maintenance.

CUTEK® makes wood protection simple. Each product is designed to highlight your wood’s natural beauty while providing long-term stability and defense against the elements. Because it penetrates deeply and never flakes or peels, maintaining your wood is quick, cost-effective, and hassle-free — no sanding, stripping, or reapplication headaches.
