Hey Sig,
I had a cypress sided, board and batten pump house built a little over a year ago. Just this weekend, I applied CWF-UV5, in red cedar tone, (made by Flood) on it. Man it sure looks great. The house is next...
Anyhow, my father is an old painter from way back and he said to wait a minimum of one season (year) to apply a sealer or stain. I took his advice and also noticed that on the back of the CWF can, it said to wait a year also. No explanation from dad or the can, but I guess it allows the wood to season, dry out and become prepared to soak up the stain. I think JimmyP5 hit the nail on the head above.
Good luck, post pics.
