Each treated board is as unique as the tree it came from and will absorb the semi-transparent stain differently, creating a variance in the degree of coloration.. Note the same application variances will carry over to the knots that dot the wood board planking.
Personally, I like the variety of tone and texture In my opinion, it has added depth and character to the decking and has enhanced the overall craftsman cottage motif.
The deck area ceiling is pine car siding. Rails and steps stained treated lumber. Decking platform, cement with decking board imprint.
Originally I was going to acid stain the cement deck brown. I have changed my mind. Now I feel the cement deck blends well with the gray Kemlite foundation covering.
