Hi everyone, im a first time poster and just started sub-contracting pressure washing for my neighbor who has a residential restortation business(I do it part time on weekends). I did my first deck today along with brick siding along the bottom of the deck. The wood was in pretty bad shape and it looked like it hadn't been cleaned in many years (mold, algae and all). This is my first machine, 3.0 gpm 2800 psi cold water. I used M1 deck cleaner on it, and at the end of the job, the home owner was really happy with it, so was my contractor, however, I wasn't. I found that the presssure needed to clean it properly was taking some of the grain out of the wood and splintering it a bit. I told my contractor that we needed to come back on it after he finishes with his add ons he's doing, with a light sanding job then seal it. Any ideas on what happened to the wood, it was clean at the end but looked rough like it needed sanding to smooth it out.
Thanks, Tony
