EXTERIOR WOOD
At CUTEK®, we are all about the wood. Wood brings colour, warmth, depth and beauty to any project. CUTEK® products offer long-term, powerful protection for wood while highlighting its natural warmth, feel and beauty.
CUTEK® Extreme has been independently tested and proven to offer powerful, long-term protection, cost effective maintenance and dimensional stability improvements that stand up to the most extreme environments. For over 30-years and across many countries, CUTEK® is the trusted name in wood protection.
Superior Mode Of Action
Traditional varnish and natural oil ‘penetrating’ type coatings work by forming a protective film on the surface of the wood to protect against moisture damage. Over time, UV rays as well as liquid and gas phase moisture induced wood movement, break down this film causing it to degrade, flake or peel. This allows water to get into the wood which can lead to cupping, warping, splitting and rot. Fixing this is costly and time consuming as the old coating will need to stripped or sanded away before reapplying.
CUTEK® is different. CUTEK® Extreme penetrates deep into the wood core and drives moisture out of the wood from the inside. This offers superior long-term protection and minimizes cupping, warping and splitting. This penetrating oil technology ensures the longest possible service life for your wood and has been proven to work and independently tested by industry experts in many countries over the last 30 years.

Self-Healing Effect
CUTEK® Extreme works differently to traditional wood stain/wood oil/acrylic/urethane/natural oils/wood coating products in that CUTEK® Extreme protects your wood from the inside out. CUTEK® Extreme penetrates deeply into the wood core upon application, protecting it from the damaging effects of liquid and gas phase water, significantly increasing the service life of your wood. It does this by remaining PERMANENTLY MOBILE inside the wood, migrating to any cut or perforation with a self-healing action.
Many products claim to be a penetrating oil finish; however, they often contain a mixture of solvents, polymers and cross-linking natural oils (such as linseed and tung oils) that penetrate only a few millimetres before drying to form an encapsulating type varnish. Because these coatings do not have a self-healing effect, once this varnish is exposed to the weather, water can quickly enter the core of the wood especially if it has been cut or perforated with fasteners leading to a rapid loss of dimensional stability. Additionally, the use of some natural oils in wood coatings can contribute to the development of unsightly mould and fungal growth underneath subsequently applied coatings. This situation can be difficult and costly to fix.
