HOW CUTEK® EXTREME WORKS

CUTEK® Extreme penetrates deep into wood to repel moisture, improve stability and enhance its natural beauty.

Unlike surface coatings, CUTEK® Extreme remains permanently mobile within the wood. Its self-healing action continues to drive out moisture, helping reduce cupping, warping and splitting, even after the wood is cut or fixed.
Proven for more than 35 years, CUTEK® Extreme delivers lasting protection in some of the world’s harshest environments.

"Protection that works from the inside out"

HOW CUTEK® EXTREME IS DIFFERENT

CUTEK® Extreme penetrates deep into the wood rather than forming a surface film. It repels moisture from within, helping reduce cupping, warping and splitting. With no film to peel or flake, maintenance is as simple as cleaning and recoating.

TRADITIONAL SURFACE COATINGS
TRADITIONAL SURFACE COATINGS

MOST PRODUCTS PROVIDE SURFACE PROTECTION

Traditional varnishes and surface coatings form a protective film over the wood. Over time, UV, exposure to the elements and wood movement can cause this film to crack, flake or peel, allowing moisture to enter. Restoring the finish can then require costly stripping and recoating.


PENETRATING OIL WITH SELF-HEALING ACTION

CUTEK® Extreme remains permanently mobile within the wood. Its self-healing action allows the oil to migrate into cuts, cracks and fixing points, helping protect newly exposed areas against moisture. This inside-out protection has been proven in some of the world's harshest environments for more than 30 years.

Warning

Not all penetrating oils are the same. Only oils that remain permanently mobile within the wood provide the self-healing action of CUTEK® Extreme.

SOLUTIONS FOR COMMON WOOD CHALLENGES

Wood is naturally beautiful and versatile, but moisture, sunlight and weather can affect its appearance and performance. CUTEK® provides preparation and protection solutions to help manage these common challenges and extend the life of exterior wood.

Wood naturally expands and contracts as moisture conditions change. Uneven movement can cause boards to warp, cup or split. CUTEK® Extreme clear oil penetrates deeply and repels moisture from within, helping reduce movement even around cuts, cracks and fixing points.

Dimensional stability is the ability of wood to retain its size and shape as moisture levels change. Protecting all accessible faces, edges and end grain with CUTEK® Extreme helps reduce uneven moisture movement and keep wood straighter.

Surface coatings can crack, peel or flake as wood moves, often requiring sanding or stripping before recoating. CUTEK® Extreme clear oil penetrates without forming a surface film, making maintenance as simple as cleaning and recoating when the wood no longer beads water.

Use CUTEK® Quickclean to remove everyday dirt, grease and grime. CUTEK® Wood Reviver restores gray or weathered wood and helps remove stubborn stains, while CUTEK® Wood Stripper removes existing paints, stains and surface coatings before restoration.

Sunlight causes exposed wood to fade and naturally weather gray. CUTEK® Extreme clear oil allows this natural silvering, while adding CUTEK® Colortone tint enhances the grain and helps retain your chosen wood color for longer.

If you want to retain the silvered, weathered appearance of the timber, protect it with CUTEK® Extreme clear oil. It penetrates deeply into the wood to help repel moisture without adding colour or forming a film on the surface, allowing the natural silver patina to remain visible.
