So maybe some of you further south guys may have some insight here…I’ve not really run into this much around our parts. It looks like some sort of pool deck coating (maybe a roll-on paint-like product) for texture…
I’m looking at you @Racer 
I’m thinking a semi-hot softwash only?
You know Rick is gonna tell you to take pictures…
It’s probably Kool Deck. I’ve washed them with the SC with no problems but I usually throw on another 100’ of hose to bring the pressure down a few hundred psi. You can definitely softwash it and that’s how I prefer to do it if it’s older.
Glad you pointed that out…completely forgot to attach them…
There are a lot of coatings you can put on a pool deck and add a little shark bite or some other additive to give it traction. I have no idea what that one is, but I know those pool cover attachment points get corroded easily and need replaced often (brass if I remember). Just a heads up so the homeowner doesn’t say you owe them for the tiedown points because your chemicals ruined them.
Sometimes the cover straps have springs and the metal will rust onto the pool deck or the straps are rubber and the black rubber wears into the concrete leaving lines. I’d take a quick look at the straps so you know if you will need some heat. Funny, pay all that money for a pool and to maintain it, then put a cheap cover on it for winter.
The white edge on the pools sometimes need repainted, especially pools with kids because they get all kinds of drag lines/scratch marks across them.
I’ve helped install and maintain pools.
Looks like Kool Deck to me.
Good job William, keep him straight, lol.
Yep, you’ve already gotten the answer. Can go either way. May sure surface is good and not flaking any before a SC on it though. I just throttle mine down some if doing those to about 2000psi but softwash will work fine too, basically a roof mix as long as it mainly mildew and not just dirt. Dirt, go with SC. Actually faster too.
I try to help where I can
Yeah, my thought was a hot/roof mix, deactivate before a super low-pressure rinse to avoid killing the grass and all. My only concern now is where that trench drain goes… Thanks guys! Never seen that stuff myself.
