1 This is a salt treated pine deck so nothing special really. I have a 12v pump and can spray the solution easily or a percarb cleaner following each with oxalic or neutralizer. Also this guy wants the undersides done, I assume a the 12.5% would be safer and better for algae spots on underside?
2 I figured 200 sq ft an hr off a past deck I had to do with severe graying and some algae. This deck in question has no algae (except some underneath) only graying. Also I added substantial time for the hand rails (230ft of handrails here) and post and also he wants the undersides of the two 1000 sq ft decks washed. And a privacy fence around the pool deck. Along with another 200 sq ft on ground level with a small outdoor shower.
3 Thanks for the tips on stains, I have sprayed paints before but only inside a home or other hobbies etc. I have been trying to push him towards a different stain for the longevity and better protection etc., but I don’t think he wants to go that route. I have a stain guy coming to look at it today to get his opinions on which stains to use. Its likely that I may have him apply the stain. I have researched and hear most people on the forums suggest either Bakers Gray away, Armstrong clark stains or Ready Seal. Ready seal being having some fading issues but is easier to apply.
4 Equipment is 4 gpm washer also have another 4gpm that I may use as well. I’ve kicked the idea around of getting an 8gpm machine to help me out and may if I pick this job up to do the flat surfaces and house washes. But I wouldn’t think I’d need that many gpm for wood.
Hey Thanks alot Rick, I’ve read enough that you are one of the gurus around here and I really appreciate it.
