Question for you residential guys

A buddy of mine just got a new driveway poured and there is some cement splatter on the cinder block on his house. The cinder block is the textured type, not a flat surface so he cannot just use a putty knife to scrape it off. Can he use something like crete relief to get it off without it eating at the cinder block?

Tell him to call the concrete company up and come back and clean their mess up…

I’m sure he has, but nothing has come of it. This is why I am asking the residential experts here for advice to give him.

I’m with @Diamond_Soft_Wash on this. If they made the mess then they should be responsible for cleaning it up. There is nothing wrong with calling them once an hour until someone gets it cleaned up. Sometimes these companies need a reminder that they can’t just ignore a customer and hope they go away.

I think it’s beyond getting them to come out and fix it. I am sure the amount on the cinder block isn’t enough to warrant even a small claims. Was just hoping I’d get some help here to help a friend out.

I wouldn’t have any idea on how to go about removing it. I bet he could call the company that did it and ask them how they usually remove such things.

Or contact a different concrete company and ask what they recommend.

Call Chad Dude.
I think,not 100 % that @pressureguy has used his concrete release.

I’d just hit it with some pressure. If it’s new enough it might come right off. Those textured cinder blocks are no different than the flat ones except for the rough edge so you won’t hurt them any unless you get crazy about it. You could even use some muriatic acid if you have to. It’ll etch the block to though so maybe do a test area below the soil line.

I was just out at the local Air Force Reserve Base doing that exact thing although it was only a little splatter on the textured concrete cinder blocks of the buildings. I just used a turbo nozzle and it came off but there was only a little bit on the walls. The rest was just cleaning up concrete dust that was piled up everywhere on the concrete.

Thanks!

Not sure the acid would work though as the cinder block is painted. Never worked with it before. We may just try a 15 degree nozzle and try to blast it off that way.

Yeah, don’t use it if it’s painted. I’d be surprised if the paint didn’t come up with it even if using pressure.

Why not just paint over it? It should blend in just fine being split face cinder blocks.

he may have to do that anyways. Wife thought she got one color and it looks more purple than anything and he was thinking of cleaning it up prior to re-painting.

Heck if he’s repainting anyway just scrape it off with-a 5-in-1.

Muriatic acid and a acid brush will take it off. If he is going to paint it you got nothing to worry about

Or just ask @gbattle , and he might just shed some hands on wisdom on this particular topic.

If it’s textured center block it’s probably cut block. You can sometimes just rinse it off with pressure, if it has been on a day or two. It depends on how much splatter it is also. Muriatic acid may help but it will kill the grass that it comes in contact with. I have removed it before from commercial painted cut block but not residential.
