Have a client that signed up for us to softwash and seal their new paver pool deck. When I went by to layout the plans, we found it is badly clay stained from the builder, all over the pool deck. He’s happy to pay us to use high pressure and resand his brand new pavers… As I thought this through, I see no reason for SH, there’s nothing organic there. Was thinking to do acid instead to treat the clay, but it crossed my mind this is a newly built and filled pool, which I’ll wager was treated with a pretty good dose of pool shock on the initial fill. It crossed my mind that this is a disaster waiting to happen, as the coping has no slope at all to keep acid runoff out of the pool. Anyone have any experience with anything similar?
Hmm. I guess it would depend on what acid you’re thinking of using but if it’s relatively close to muriatic I don’t think it would be a problem at all. Pool guys use muriatic for acid washed to remove all kinds of stain although it is diluted before going in the pool but so would your acid, I’m assuming.
I’ll ask my buddy what he thinks on Thursday when we install a pool, if your still interested. The pool filters will handle more than you think if the homeowner runs them right. If your worried just buy them new sand, 3 bags is about the norm.
Pool water is about PH and keeping crap out of it. Since clay is likely alkaline, I think the acid might neutralize that. That is just a lunk head installers thought, the professional would know.
Pic would help. But acid is fine. You’re just going to get a little in pool and it’s already going to be diluted. I use it on bad mud stained pool decks often. Just tell them not to swim for a few hours
I figured I was overthinking it…
I’m confused on the concern now? So I think I know that muriatic can have bad reaction with SH but if pool is empty what’s was the issue?
Those pics were a few weeks ago, pool was filled 2 weeks ago. I tried to tll him to sequence things properly, but he held us off and didn’t tell me the timeline on the pool work/fill until he had them booked to go, and we couldn’t get ahead of them because he wouldn’t decide what he wanted to do (I wa only going to softwash new pavers/sand, but then he wanted the clay treated which changed the plan).
LOL, how can you even see mud stains, whole thing is mud colored.
NMD80 - go watch their videos on hardscapes. Be sure to get their EC jet if you don’t have one, about $150 if I remember. May not have to use surface cleaner, may just be able to rinse with like M5 tip; but depending on sand used, SC shouldn’t bother if you keep it around 2000psi
