Question Cleaning Brick Walls

The exterior walls of my house are speckled with either old paint or a chalky white substance. I have tried muriatic acid - and all that did was make the bricks look pink and turn the mortar yellow. All the brick has this problem. I don't know if someone was excessively sloppy when painting the house or the builder got a "deal" on defective brick.

Any ideas on how to remove it?

There is a product called "Goo-Be-Gone" that will remove paint.

If you are talking about a really big project, and it really bugs you, hiring out to have the brick sandblasted will make it look good as new.

Woodbadger: I have a similar problem in my kitchen with the thin brick wall. There appears to be a few 1" wide short swatches of green "paint" on a few bricks. i am not sure if they were cheap bricks as well. Is there a way to sand the brick material to remove some of the surface? I do not want to pop those out and replace with new ones because theroom will be complete in 1 week and I am out of time before I move in. Thanks for all your help and sorry to jump in another forum and ask a question.

As for the "goo be gone" stuff. It works great on carpets, walls, and car paint to remove gum, paint (splatters on a smooth finish), old adhesive, etc. I may try that too. Peace: e3 - spamman

You want to be carefull when working with brick wall covering. If you sand it, the sanded section will look lighter then the other sections. I have also seen interior brick that has color just on the finish side (so if you sand it, it looks tan instead of red).

I would try Goo-Be-Gone or some other paint softener to remove the green paint.

Note: try it in behind the stove first to make sure you don't create a bigger problem by discoloring the brick.

Note2: use a lot of water when removing the paint so it doesn't wash into the brick farther down the wall.

Thumbs up

Thanks. We actually removed all the brick that was in the old cabinet section, replaced with new sheetrock, put up the formica backing and now installed the cabinets. I am not too keen on the brick wall but it will do for a little while till we redo that wall. i will try the goo gone. Peace: e3 - spamman
