Wood protection, passed down through generations
CUTEK® loves the look and feel of wood, and sets out to provide the best wood protection solutions on the market. The company is passionate about the sustainability of the lumber industry — without wood, there would be no need for wood oils.
As a family business passed down through generations, CUTEK® is committed to helping the lumber industry thrive for generations to come.

The CUTEK® system is built around two simple steps: Prepare and Protect. Start with CUTEK® Wood Stripper and/or CUTEK® Wood Reviver to get your wood clean and ready. Then protect it with CUTEK® Extreme clear oil, adding a CUTEK® Colortone to maintain or change the color. Then maintenance is as easy as a wash with CUTEK® Quickclean and a re-coat with CUTEK® Extreme, no sanding required.
Vertical Grain Pine — CUTEK® Extreme Clear Finish
Vertical Grain (VG) Pine is a premium cut of pine milled specifically so that the growth rings run perpendicular to the face of the board — typically at 60° to 90° to the surface. This "quartersawn" or "rift-sawn" orientation produces a board with a tight, straight, pinstripe-like grain pattern that is dramatically more stable and refined than standard flat-sawn (plain-sawn) pine. Because the growth rings are oriented vertically, VG boards resist the cupping, twisting, and cathedral-pattern grain shifts that flat-sawn lumber is prone to, and they wear more evenly over time — which is why vertical grain has been the traditional choice for high-end architectural applications like porch flooring, exterior siding, boat decks, and fine millwork.
The visual character of VG Pine is one of its biggest selling points: consistent, linear grain lines with minimal figure or knots, producing a clean, understated appearance that reads as more formal and architectural than character-grade pine. This makes it particularly well-suited to applications where the wood is a design feature rather than a background material — traditional porch ceilings, Craftsman and coastal-style siding, wainscoting, and interior paneling.
Each board is finished with CUTEK® Extreme Clear, a penetrating oil engineered to stabilize exterior wood from the inside out. Rather than forming a surface film like paint or varnish, Cutek carries its oils deep into the wood fibers, where they work continuously to slow moisture movement — the primary driver of cupping, checking, and end-splitting. This is especially valuable for pine, which is more naturally susceptible to moisture-related movement than denser hardwoods; CUTEK®'s stabilizing action significantly extends the board's dimensional life outdoors. Because the finish penetrates rather than coats, it cannot peel or flake, and maintenance requires no sanding or stripping — just clean the surface and reapply when it looks dry. The clear formulation adds no pigment, allowing the natural honey-gold tone of the pine to show through initially before gradually silvering to a soft gray patina if left unmaintained with a colortone.
Ideal for porch ceilings, tongue-and-groove soffits, traditional lap or shiplap siding, wainscoting, interior paneling, and any application where a refined, straight-grained wood aesthetic is desired.

Frequently Asked Questions
Traditional varnishes and many "penetrating" oils form a film on the surface of the wood. Over time, UV rays and wood movement break down that film, causing it to flake or peel and letting water in, which leads to cupping, warping, splitting and rot. CUTEK® Extreme clear oil is a true penetrating oil. It diffuses deep into the wood and drives moisture out from the inside. Its protective components stay permanently mobile in the wood, migrating to any cut or fastener hole and sealing it against moisture. This "self-healing" effect is what makes CUTEK® the professional's choice for long-term wood protection.
Step 1 – Prepare: Clean and enhance your wood with CUTEK® Wood Reviver, CUTEK® Wood Stripper or CUTEK® Quickclean. Step 2 – Protect: Apply CUTEK® Extreme clear oil, with a CUTEK® Colortone added if you want to hold or change the color of your wood.
No. CUTEK® Extreme will not peel or flake. Over time, wood exposed to the sun will fade and a CUTEK® Colortone can wear with use. When that happens, simply clean and apply a maintenance coat — no sanding or stripping required.
Yes. CUTEK® Extreme stabilizes wood by controlling the free exchange of moisture between the wood and the environment. Because it stays mobile and self-healing, that protection continues even when the wood is cut or fastened, improving dimensional stability and extending service life.
Yes. Each additional coat of CUTEK® Extreme adds more protection against moisture. The more consistently you maintain your wood with CUTEK® Extreme, the better protected it becomes.
No. CUTEK® Extreme must be applied to bare, clean and dry wood. Existing stains, paints, linseed oil, polyurethane and water-based finishes block penetration and must be fully removed first with CUTEK® Wood Stripper followed by CUTEK® Wood Reviver, or by machine sanding.
CUTEK® Extreme can be applied to new wood without preparation. For the best results — and especially if you're adding a CUTEK® Colortone — we recommend CUTEK® Wood Reviver first to clean the surface, open the grain and remove tannins, mill glaze and other stains.
Use CUTEK® Wood Reviver. It removes the grey and brings back the original color and grain of your wood before you apply CUTEK® Extreme.
Clean it with CUTEK® Quickclean to remove dirt, grease and grime, then recoat. If maintenance has been neglected and the wood has greyed or become heavily stained, use CUTEK® Wood Reviver before recoating.
Stir CUTEK® Extreme thoroughly from the bottom of the can (with your CUTEK® Colortone mixed in, if using) before and during use. Apply thin, even coats with a brush or paint pad applicator. Two or three thin coats are much better than one or two thick coats.
Yes. Wood coated with clear CUTEK® Extreme can be installed immediately or block stacked wet for later use. We don't recommend wet stacking wood coated with a Colortoned CUTEK® Extreme, as it may create an uneven, smudged finish.
