Often times, if not every time, I get asked what color is the wood board, or shingle going to be once it is washed and stained. The answer varies. Every board is different. Every deck is different. Every circumstance is different.
Here is a random example of a wood deck in Aptos California. The boards on the left side of the picture are cleaned and still wet. The boards on the right are stained with a mixture of natural brown tones. Tones are almost impossible to describe. Beading water isn’t.
