All CUTEK® exterior wood oils are sold as clear, and if applied without an added colourtone they will cause the timber to quickly lighten naturally into a beautiful silver patina on exposure to sunlight and UV. Add one (1) Tin per 5L and two (2) Tins per 10L to Extreme CD50 Oil CUTEK® Extreme CD50 and CUTEK® Wood Preservative diffuse deeply into timber and will continue to provide moisture protection and improve dimensional stability even if the CUTEK® Colourtones are not added and the wood becomes weathered and grey. If you would like to retain the natural freshly oiled colour of the timber you’re working with, you MUST add a suitable Colourtone to the clear oil. Choose one of our various Colourtones which have been specifically developed to closely match many popular wood species. For best results, select a CUTEK® Colourtone that stays close to the natural shade of the coated timber.
