I'm not a woody virgin any more! Did my first deck (pressure treated pine) today using Bob's chemicals and guidance (THANKS BOB!!!) Used F18 straight at 2 oz per gallon sprayed with my Bobcat and Bob's neutralizer / Brightener downstreamed at 9 oz per gallon in my bucket. After spraying the F18max and a 15 minute dwell I used my dual lance and 25* nozzle cutting my pressure way down with the dual lance to wash the old weathering out and then the brightener. This really surprised me. The deck was really rough and I thought it wouldn't come out this good. Only a few splinters and a small area furred. Minimal (maybe 10 minutes work) hand sanding will be all that's needed. Only one railing really needs replaced before I come back and seal it, that board was fairly rotten and had a wild vine growing on it at one time the home owner said. Plan on using ReadySeal to seal it. What ya think?
