The Natural Color Evolution
While the brown color is the natural result of our thermal modification process, the silver is a result of wood’s natural aging process through exposure to the elements. UV light and rain both accelerate the aging process – the amount of exposure influences how quickly your project will age. With direct exposure to sunlight, your project may age to silver in as little as 6 months. To preserve the original color outdoors, boards must be maintained with a penetrating protective oil.
