HELP...spray paint on brick removal.

[dadsEH]

One of my neighbours bought an older home which has pressed brick walls. The previous owners must have been hippys cuz they took to one of the garage side walls( exterior) to try and make a mural but ended up with a puke yellow wall sprayed with rattle can paint...what a mess.
so the neighbour wants it gone.....
he has no idea..i.m thinking bead or soda blasting. He said he had a quote for 3k$....its only about 15 ft x 8 ft high....the pro said he wouldnt do it cuz it was too small a job...lol.

so whats out there in DIY land guys????

I have used oven cleaner to loosen the paint with good success. Never used it on brick or grout though.
Zip strip might be an option also.
Follow with a good wire brush scrubbing and a pressure wash? Just guessing here, but I think that is how I would approach it.

I don't know if you guys have Soy Gel in Oz, but that is what I would use. It's good paint remover, will not burn skin, dries out slowly, and rinses off with water. Will probably take several gallons, but it won't hurt the brick.

Cheap rattle can paint can be brought up with cheap rattle can clear coat. Its a long shot but try spraying a thick runny coat of clear on it quickly then before it dries hit it hard with a pressure washer and see what happens.

I know thos works on uncured paint as I have done art projects this way but hard to say with this situation.

Most spray paint especially if its not been clear coated well will not stand up to being scrubbed with paint thinner/mineral spirits. Get some green scotch brite pads and some good runber gloves and probably a face mask respirator (not a white cloth painters mask but a decent one) and go to town.

Good luck.

I just cleaned a bunch of graffiti off a building foundation using a pressure washer.

Propylene glycol methyl esther acetate and potassium hydroxide. It may be biodegradable, but it is not non-hazardous.

I wouldn't know how to handle that much without damaging the brick face, but I can tell you what I do on smaller issues.

I just find "brick" colored, textured paint and spray right over it.

There's really nothing stopping them from doing that over an entire wall, really. Hell, I'd try it if the probability of success with other options looked bleak.

Need some curb appeal really, really fast, but have misbehaving bushes for whatever reason? Paint them green. I did that the last time I moved.

Trees not looking quite right? Paint them. I've done that for someone else, though even I was scratching my head over that... Tree trunk not the right shade of brown where it had been cut in the past? Really?

It's amazing how long the stuff will last. It seems when you paint something that's supposed to be painted, the coat never holds up as well as you'd like; but get that **** on ANYTHING else and you'll be looking at it for the rest of your days.

3k ????????? OMG.

Why bead or soda??

It's outside, and not a "Delicate" surface.

Uhhhhh..... How bout just cheap old fashion silica sand blasting?

Nothing big or Pro needed.

For that area a 5 hp comp and a 60 lb pressure pot probably should handle it in 2 hr, maybe a bit more.

$20 - 30 in sand per my experience.

Darn Hippys.

Try 'peelaway', Its a paste and paper system. Slap on the paste and cover with their special paper and it lifts the paint off. Make sure the paste is into all crevices, keep it damp by spraying the paper with a spray bottle of water. Final clean up with hose and scrubbing brush after scraping off the bulk of the paste and lifted paint. I've used nearly 60 kg in the restoration of my place. It still involves effort but its the best I've found.

Ya, actually start w that, may be enough.

But a decent one, not an $59 one from Home Depot. Marc

Yeah it needs to be a good one. I think the one I used was 3700 psi. Started with wide tips and worked down to stronger tips until I had it all clean. No need to overthink this. If anything let some thinner soak on it before power washing.

 

[dreamingmuscle]

Rent a good pressure washer. Steam cleaner might be faster but more of a hazard..

I worked at a public school where we periodically had graffiti problems. There are spray graffiti removers but we usually just soda blasted it. Nothing toxic and it works well without harming the brick or mortar.
You will be blasting with about 100 lbs of pressure. If it has old soft brick and soft mortar, I would not hit it with a 2000 psi or more pressure washer. Also, if it is soft mortar (lime, not portland) repairs need to be done with soft mortar. You said it is an older home, so it could be soft materials.

VERY bad advice. Believe it or not, brick can be very soft. Sand will eat it & the pointing away.

Exterior brick has a thin face that is hard, during the heat firing this face gets created. Once that face is gone the soft face is exposed and then the brick going to weather fast. Only walnut shells and soda blasting are viable options that I am aware of.

Looks like I was wrong, was not aware. Thanks for correcting. Marc

Hydroblasting with ground glass is just about as abrasive as straight sandblasting. Probably not a good fit for cleaning paint off brick. I am a fan of using this process to remove paint from project cars.

 

[Loose Ctrl]

There is a company out there that makes an attachment that runs soda through a pressure washer. It works well and it's what is used when the kids start tagging each other schools around me.

I second this (though I've never tried it on brick, so a small test area would be wise before going to town on it), but use "Peelaway 7" as that won't chemically change the brick color, where "Peelaway 1" may cause undesirable chemical reaction color change. Naturally "Peelaway 7" is more expensive, but it's less toxic than "Peelaway 1". (avoid skin contact - wear rubber gloves)

Goop it on - cover with special waxy tissue paper that is included in the can - leave on for 16 to 24 hrs - wash/scrape/brush off - last step = spray with vinegar to neutralize cleaned surface.

I know almost all hardware stores around here sell quarts and spray cans of graffiti remover for most surfaces, usually lists its primary use as on concrete and brick surfaces such as bridge abutments and buildings. Pretty easy to find

Lots of good ideas, but before offering any of my own I'd really like a definition of the term I noted above. Could be any number of actual materials.

 

[dadsEH]

By pressed brick ....im referring to the manufacture of bricks using an extrusion die and wire cut to thickness.the brick tends to have a porous surface compared to molded bricks but still very hard .
