Unless a clear finish that will naturally lighten/silver/grey off in a few months is desired, it is important to mix oil before use.

CUTEK® EXTREME CD50 OFFERS SUPERIOR PENETRATION AND DIFFUSION WITH A SELF-HEALING EFFECT

CUTEK® wood oils work differently to traditional wood stain/wood oil/acrylic/urethane/natural oils/wood coating products in that CUTEK® oils protect your timber from the inside out. CUTEK® oils penetrate and diffuse deeply into the wood core upon application, protecting it from the damaging effects of liquid and gas phase moisture, significantly increasing the service life of your timber. It does this by remaining PERMANENTLY MOBILE inside the wood, migrating to any cut or perforation with a self-healing action.

Many opposition 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 timber 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.
