hello to all , thanks for taking a minute, three years ago I applied semi transparent stain to a weathered deck , had not been previously stained.
I power washed with a deck conditioner first, allowed it to dry completely.
I had done research and told my costomer that it would probably need some more in a few years.
So, I looked at it recently and it looked like it held up pretty good for the most part, but two boards in the middle (horizontal )have almost all of the stain worn off

and the top rails, which were not in the best shape to begin with now had wide deep cracks running all the way practically from end to end. Ofcourse I replaced the top rails, and threw a light coat of the same stain over them right away .(Don't fret it was pre treated and weathered )
So here is the question, before I do anything else to this deck, which by the way belongs to the owner of a large repaint apt. complex that my co. has maintained for almost ten years, I want to make the right move with the right product. What bothers me is I used (brace yourself guys I am about to say the B word ) Behr waterbase semi tr stain . Just thought I would ask for some imput before I proceed. What would you put over this?
I know I have to go solid right ? Or can I switch to just a clear sealer?
I don't mean to sound like a rookie here, I am well seasoned in many areas
but, well you've all heard this before, this is not my specialty. Thanks Mac2
