Cutek Extreme is a unique wood protection oil which keeps wood and engineered timber looking great for many years. It comes as a clear oil, with a choice of 10 colourtones which can be added to enhance the natural look of your project. Cutek Extreme is formulated to minimise warping and cupping and splitting, which means your exterior project lasts years longer. Clear Extreme fades over time, but retains the natural wood colour months longer than clear Cutek CD50, minimising maintenance requirements for timber. With a colourtone, the added UV protection keeps the natural colour for much longer.
