OK guys have an interesting problem I don’t have expirence for. I have an unstained heavy UV damaged deck I’m set for on Tuesday. I have seen and followed everything I can but running low on answers. I mostly soft wash roofs and houses using a bandit kit from Bob. So direct application. I have a similar fence out back I’m trying things out on. House wash dwell 10 minutes and rinse was hardly noticeable. Then I tried f18 followed by f8 about 5 minute dwell time each on an unwashed section. Better but not the night and day difference I’ve seen you guys do. I have f10 coming asap. Will the f10 followed by f8 yield what I’m looking for? I don’t have a commercial power washer yet. But do have a small 1.2gpm 1700 psi. Should I use this or maybe try brushing the f10? I’m at a loss here guys help.

Chemical test vs power washer. The left is straight power washer no chems. The right is f18 direct applied and 15 minute dwell followed by f8 also direct application same 15 minute dwell. I rinsed with a fat boy 7 GPM 0 tip thoughts?

Nonsense. The correct selection and chemical mix on wood does all the needed work. If you have any clue of what you are doing, a pressure washing is only a glorified, quick scrub brush, at low pressure. The correct chems and dwell time and a good rinse does most of the needed preparation.
Just came on this board after meeting Thad, but have to say, flat work/house/roof/ whatever PW contractors have a lot to learn about wood.
We use Dsr 50 from powerwash.com - it’s sodium hydroxide … Followed by oxalic acid… Wood looks brand new when we are done…
The wood looks bleached… What is f18?
