Used for our Termoholz terrace for several years. At the beginning I was not thrilled because I imagined that it is actually colorless. That's not so! After a few weeks it will be but "better" and the wood looks in his coloring again natural.
Our open-top terrace gets the first resistant warmer days in a single coat. This is sufficient. (Wood brushing previously well and dry out again. Color stir tidy. Just a little oil applied.)
