I've been looking at this paint job for four years, wondering what beautiful bricks might be beneath the tan, white, maroon and peach layers.
I like to do my research before tacking a new project, soI've read a few other blog posts about stripping paint from fireplace brick. Checking these posts helps me get pumped up to take on the project! I want to give a special shout out to a few of you:
I went into this project expecting the worst. I expected difficult labor, lots of time, elbow grease, strippers, soda blasters, brushes, drips, stink and a very unhappy husband.
So I gathered some supplies... I am using a few different brands of each product that we have left over in the basement. On the woodwork we've been using Smart Strip, but I wanted to polish off the other cans of product in the basement.
Then I ran some tests. First, applying chemical stripper straight onto the painted brick. A test with stripper applied to the paint:
Stripper alone doesn't cut it. Even two applications didn't get to the first layer of paint. This might be a point where a specific product would be preferred (insert your favorite product here).
In another spot, I tried hitting the paint with the heat gun, scraping off what I could, and then going after it with the chemical stripper. The heat gun made a huge different, as you can see. It really loosened the paint's grip on the brick. It wasn't too impressive though- it felt like trying to comb gum from your hair. Really stick gum. And not your hair, but maybe a teddy bear's hair. But after the heat gun, the stripper worked very well.

The heat gun takes roughly 3-5 minutes per brick, and I use my painter's tool in a chiseling fashion, scraping away some of the paint.
The chemical stripper sits on the brick for about 15 minutes. Then I scrap off some goo with a plastic scraper. Next, I dunk a wire brush or steel wool (I use either and my preference varies as I work) in mineral spirits and scrub off the residue. It takes about 5-6 minutes to scrub each brick and the neighboring mortar.
I haven't used the vinegar to remove the residue yet because when I went to grab it from below the sink, I saw a Magic Eraser and thought that would be an interesting experiment. Of course, the eraser disintegrates quickly, but it definitely did the job. However, it doesn't really get into the crevices well. I'm hoping vinegar and a towel will have better results. But still, not bad. This last picture shows a few bricks that I wiped down with the eraser. You can see a slight change in the color- the flatter gray is residue stained by the mortar. The bricks themselves are a color similar to sidewalk concrete.
I took this picture before finishing for the day. I have about half of this side of the fireplace cleaned down to the brick and it took about half a day. It's really not bad at all. I feel very lucky that it's going this well!
