I have a 60yr old red brick house with all wood, white trim... the previous owner(s) must have either been dumb, blind, lazy or the worlds worst painters becuase EVERYWHERE around the trim they over painted onto the brick.
You cant see it from the road or at first glance, but it certainly is there, and its everywhere... pisses me off to no end. I've tried industrial strenght paint strippers of evry damn flavor and color with a wire brush, pressure washers, you name it. That sh!t doesnt budge. I couldn't imagine doing an entire fireplace. It just would be a monumental task I would think.
I have an inside wall that is part of an addition that they paitned white... about 300 times too I think the stuff is so think... I would LOVE to get it natural brick back.
Thats why I shutter whenever I see a brick house that has been painted or when on those home redecorating shows they paint the fireplaces or generally screw with the brick... its just so evil.
Anyways, if you have any luck short of repainting
PLEASE let me know. This trim crap on the outside of my house is driving me nuts!
