CUTEK®

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.
