Wet sand blasting curbing

JL Pressure Washing
Anyone have any experience with wet blasting attachments for your pressure washer.
I have maybe 1000' of curbing in a neighborhood that has been painted a few times and they don't want to paint over the olf and flaking paint, because of course it will just peel/flake off again.

I am going to do a test with just high pressure tip and also roto nozzle, but I already know whats going to happen. It will only get some of the loose stuff off and maybe some of the tight paint off but not all of it. Then I figure some of the tight will lift as we move on down the curb

Some areas the paint is very thin other areas its cracking and lifting and has a few layers. Doesnt look hard to get off with wet blasting I have done tons of sandblasting, I just have never used a wet blast attachment on a PW'er

Wondering about the attachments, I see plenty on the web, wondering if there's any better than most or all about the same?

WONDERING how big of a MESS it makes.. None of the curbing is really close to any buildings just in neighborhood parking areas or connected to some sidewalks.

wondering what kind of grit is used? Is it just a white or light brown sand, if I pick up heavy areas of grit could I just wash the rest away to grassy area. I am thinking in some areas it will just go into the grass, the grit and small paint chips, I'm thinking just rake it into grass and on road just push into piles and shovel up

What about time, does it go fairly fast?

what about rates to charge.

If anyone has used the attachments, what do you think, are they good or a PITA to use


Thanks

Back in the day I used that attachment on my wand and sand blasted & painted roll off's for the city. It worked real well, but we were in the middle of a field so there was no issue with the sand left from the work? We charged by the unit on these but if I was doing a painted curb it would be at least .50 a linear ft.

What kind of grit/sand is used Nick?
 
Several years ago we removed paint from a curb at a high-end retirement home.

We used water only. 8-10 gpm, 3000 psi, 180-200 degrees F.

We swept up and bagged the paint chips for the customer to dispose of.

We tried to remove old multilayer striping paint awhile ago from a garage facility (concrete) and the turbo nozzle was the factor of cleaning, not so much the heat. We couldn't remove the paint completely though.. I think the right equipment for this kind of cleaning is sandblaster or hydro blaster.

It left a huge mess afterward which you should keep in mind.

I don't know it they have one that would work for curbs, but Sherwin Williams rents grinders to remove paint from concrete surfaces. They have different grits depending on the surface. I don't know if would work for this application, but you might give them a call.

If it would work you wouldn't have as much of a mess to clean up after.

I'm surprised you got that much off. Striping paint is usually pretty tough

yeah right....25 lbs and probably 15 yrs ago :cray:
 
I doubt the high pressure alone will do the job for you at a reasonable pace unless you are over 5000 psi. Sand probably may not be a very good option for you it is messy and will need to be cleaned up. You may want to try dry ice blasting. When you are done the product evaporates into the air you will just have the paint to deal with then.

I say you order a SODA Blasting Machine from Tom Vogal, He was selling them cheap last roundtable. 400 bucks
 
Did a test cleaning stripping in several areas with just pressure, roto nozzle, green tip, heat. Came off real good fairly easy. There are a few layers and the bottom layer in areas is real tight. Found out when they last had a company paint it, it was November, it was cold and it started to rain and THEY KEPT PAINTING DUH

They were happy and the district manager was there and signed two other proposals for building wash & sidewalks on the spot and got a call today to do the curbs too. There other regular wash company said they couldnt do the curbing, couldnt get it off. Guess who is now the new regular wash company? Yup JL

Glad it came off, little time consuming in areas.
