YouTubeHas anyone here any experience with removing paint from sandstone lentils on their houses? Any recommendations on technique and chemical strippers etc would be appreciated. Same goes for brick if anyone knows.

NO SANDBLASTING
sorry... don't mean to yell. but really it will seriously damage brick. It's not so bad on the stone, since the material of stone is a more uniform consistency, but it will damage any material regardless.
Find a contractor, use ProSoCo, a chemical stripper.
If you need horror stories on the sandblasting, I can show you multiple examples. Even pressure washing can be a huge problem. I remember watching a very respectable contractor power washing a brick building. The water ran red like blood, from all the material being stripped off the building, and I watched as the guy ran the water wand over a stone lintel. You could see the water slice into the stone like a knife through a loaf of bread.
Just don't do it. Use a chemical stripper. And use patience... it may not get every speck of paint off, but results will improve over time.

Thanks, Heysquare. That's an informative article. Thanks. I need to call around to some masonry shops around town and see if they have any of the agents needed to remove the paint. I have a feeling it's going to take multiple applications in order to get it all off. I can't imagine how many hours it will take but it will definitely be worth it.

well theres many different types of "sand blasting" that can be done. sandstone is incredibly porous and i would think chemicals would stain the shit out of it. they have a system of sand blasting that uses powder like sand and low pressure, minimal pitting and damage. the issue with the surrounding brick could result in damage or color change so people tend to mask off the portions that are not getting blasted. depending on where you live ie vic vill,
they will not let you do any kind of sand blasting. sand blasting is not as destructive as people think, you just need to have it done right.

A friend of mine had powder blasting, the least damaging of the blasting techniques, done on his building to clean some of the sooty residue from it-- the Diamond Exchange down on Gay Street. It's a stone building. He was happy with the results when it was finished; however, there has been accelerated damage to the stone at the foundation. It's been a big concern.
