UV rays cause colour pigments to fade over time
That is why you should use „sunglasses“ for the wood. UV rays change the colour of the wood. It can turn grey and yellow and thus lose its original colour. SAICOS UV Protection Wood Finish Exterior is a satin finish with a natural oil basis that counteracts these changes. Colour pigments with high UV resistance keep the wood beautiful in the long run. The stain is also water-repellent, moisture-regulating, easy to apply and extremely economical.
