I wouldnt use a pump sprayer for anything except hard to reach crevices porch area sometime around porch. My pumpup usually has leftover housewash in it and I bump it up a bit. Sometimes Ill get that piece of rafter that the algae wont budge and the stronger mix helps me with it.
2-3%, a house wash mix really doesn’t do much on concrete.
Do I just let the SH dry when post treating?
Correct. After it’s cleaned post treat is left on there to keep cleaning.
It’s been discussed on here quite a few times but it’s not recommended to use a backpack sprayer. Bleach will eventually cause a leak and it could cause chemical burns. Someone had this happen to them using a backpack sprayer.

very glad this subject was raised, I’ve never post treated and was thinking about the pool deck we are doing at the weekend, its already in good condition so I would really like the customer to still say wow, if I finish with a post treat how long before the family could use the pool ? once its dry or ? ( I have already asked customer to have the pool guy come after we are finished to do the ph balance)
Why, are you cleaning the inside of the pool? I’d never tell my customer to get their pool guy to come check behind me, if I’m just cleaning the deck. Shouldn’t get much in pool except a little runoff from side of surface cleaner. If it’s already in good shape, don’t need to do much of a post treatment, just ds some straight SH.

There is a trench drain which runs all the way around the pool, we will be cleaning on both sides, forgive my ignorance but will the SH not get in to the pool system ?
My question was actually about when the family can use the pool area ?
Are you sure that trench drain feeds into the pool? I think most of them around direct water away from the pool.
A little SH isn’t going to hurt. Don’t use surfactant, down stream the sh like Rick said, and just don’t go nuts with it. That pool deck is pretty clean anyways. Even if the trench drain does run into the pool the SH shouldn’t hurt. The pool might need vacuumed afterwards though. I always thought they ran back into the pool but I’m not positive. A public pool would lose a lot of water if they didn’t. Private pool wouldn’t matter as much with only a few people getting out every so often.
Hi Jim, not sure, I always thought the water went back in to the pool, which is why I was concerned about the guys kids jumping in it after I finish and getting thier hair dyed 
Thank you Marine ! I will check with the customer just to know for sure. Good info on the surfactant, never thought about it but actually I can just imagine the soap and the pump 
bravo thank you

Most, if it goes back into pool, gets cycled thru filter system first. It’s like part of the skimmer system.
That’s a huge pool, any normal SH you used, with a lite amount of surfactant, if any, not going to effect anything. LOL, don’t be using Sodium Hydroxide or anything like that. You could probably dump 5 gallons of straight SH into that pool and in 10 min no one would know.

Hey so I don’t think it’s been exactly specified on this feed, so what is a good mix (generally speaking) for post treatment? I really like to make sure striping is practically non existent when I finish. Really like all the info on this feed! You guys are awesome and helpful.
With a good clean, 2-3% should do the trick. At times might even need to hit it with 50/50 just depends how well your equipment cleans and dirty the concrete is to start off with. You can never have a too strong post treat, it just becomes wasteful if it doesn’t need it and more chance of burning up grass edges.

I have been wondering this @MuscleMyHustle as sometimes recently 3% hasn’t been cutting it for a pretreat and sometimes post treat and I’ve gone up to 4-5% before it was effective. Thanks!
