How to Remove Stains from Brick
LESLIE: Now we’re going to go out to South Dakota where Wade is looking to get rid of some stains on the brick.
What kind of stains are you seeing?
WADE: Well, I think it might be [some age] (ph) with some hard water staining and just plain old dingy.
LESLIE: OK. Is it in a large area or is it pretty small and concentrated?
WADE: It’s actually a pretty large area. I’ve got – it’s actually just like an accent wall on a building; on a business. I just had it repainted and it’s, oh, probably 20 feet high, 40 feet long.
LESLIE: Now if it was unfinished brick I would say to use TSP, but what would you think we could use on a painted brick, Tom?
TOM: Well, with a painted brick – have you pressure-washed it to make sure you’re getting any deposits that are on top of the surface off of it?
WADE: We did, we did. And it’s a dark brown so the spots show up pretty good.
TOM: Yeah, if you’ve tried to clean it and you can’t get rid of those spots, the only other option is to paint it again. Because you know what comes after paint – repaint. (Tom and Leslie chuckle)
WADE: Right. Exactly, exactly. Hate to do that.
TOM: But this time you want to make sure that – you probably should reprime that surface with an oil-based primer to make sure you have really good adhesion. And if there’s any loose paint underneath that, you’ve got to get that off or it’s not going to happen; it’s just not going to stick.
LESLIE: And what about if you use like a KILZ primer that would kill any sort of whatever this material is that’s causing the stain?
TOM: Yeah, and get a power sprayer. Try to spray it on and it’ll go on a lot easier for you.
WADE: OK. OK, well thank you for your help.
TOM: You’re welcome. Thanks so much for calling us at 1-888-MONEY-PIT.
