go to the paint store and get a bunch of brick colored samples and go home and see what samples best match your brick and after you scrub off as much white and blue paint as you can, just touch up paint the brick with the brick colored paint.

try heavy grit sandpaper. it will get most of the paint off.

Even the pros use tape!

Wire brush to loosen the paint, and then sandpaper it off, or use paint remover. Regardless, I'd wire brush it first before following up with the paint remover.

You should be able to sand most of it off. Use the corner of a scraper for the hardest parts or go all out and get a rotary wire brush to use on your drill. If there are faint remnants when you're done, match the color of the brick with some paint and give it a light coat, brick by brick.

Use a dremel with a wire brush and then a sanding attachment, should take care of it.

I apologize for not having any advice on how to get rid of the painting, but I love this color! You picked a great color.

I would paint the inside of the brick a contrasting color to look like a doorframe.

They sell stuff called Lift Off at the hardware store that is a latex paint remover (it comes in a little yellow bottle). Try that with a small wire brush (like toothbrush size). I originally bought that stuff to get old paint drips off a brick fire place in my apartment, then used it again when i had a little sloppy paint moment on my mother's stone fireplace. it works really well (though I might tape off the door to block any spray or drips). if all else fails, I'd get a couple of brick-colored outdoor paint samples at the hardware store and dap them on the brick to blend together and match.. good luck!

Be sure to use tape when you paint the inside of the brick to look like a doorframe :)

Use a clothes steamer and a wire brush.

i used rubbing alcohol to get paint off of some surfaces INSIDE my house... maybe that will work outside?

Read up on SoyGel by Franmar. It was awesome for removing paint from our concrete floors.

I should have added in the above post that I don't know for sure whether it works on brick, but I think it should. (Hence the recommendation to 'read up' on it - check the specs at the Franmar website.)

The removers suggested by others may be cheaper - not sure.

If you can't sand it off or otherwise remove it, or if you decide painting might be the easier route, I would make it look intentional by picking up the black of the nearby railing and hardware and paint the concrete door frames (including the light blue part at the base) and the interior section of brick where the markings are a flat/matte black to match the door handles (at least they look matte in the photo!). The railings and light look a little rusty/worn too; you might sand those a bit and repaint all of it at once to tie it together and freshen the whole thing up a bit.

p.s. I like the pop of yellow flowers with the blue door but the yellow pots may be overkill. If you go with the black thing, I'd swap those out for black ones -- maybe square, to play up the angular lines of the door frame and doors themselves?

p.p.s. Don't forget tape this time!

I'd also recommend taping off the paint you want to *keep* on the door when you go at it with cleaners/wire brush/elbow grease/whatever you chose to use. That way you can clean away and not worry so much that you're going to damage the paint on the door.

I agree that the yellow planters with that door are extra keen!

I'd probably mask off the blue-painted door (so as not to make the same mistake, in reverse), then carefully apply some gel paint stripper with a small brush. Keep wiping off the liquefied paint (maybe even use an old toothbrush), keep applying more stripper & keep wiping off as needed. Then wash of the stripper residue with a wet soapy sponge.

Ack, what a mess indeed. Painter's masking tape-- don't ever paint without it.

I actually just used some of that citrus paint stripper on my wood door frame, and some of it got onto the bricks in the removing process and it was a mess. It liquifies the paint but then smears it into the porous surface of the bricks. So personally, I would first try the physical sanding/scraping method before resorting to a chemical stripper.

Didn't you notice you had done this when you did it? Next time, wipe it off while it is still wet. Although brick is so porous, maybe that isn't a good solution, come to think of it. You might wind up smearing it more.

Sandblasting, or sand the hell out of it by hand, then subtly as possible paint over what's left of the blue with a custom brick colored paint.
Your not trying to get the paint off, but out.

Realistically, I think renting a sandblaster (one day rental) is your best bet.

Turpentine! That takes out paint, doesn't it? You can get that at Home Depot or hardware stores.

I think it would be awesome to paint the edges and the bottom of the brick a coordinating color.

"Goof Off". that's what contractor's use.

good old spray on paint thinner. it'll just start to bubble up and you wipe it off with a rag. i got all of the factory paint off my bike frame that way.

Try a heat gun--you'll have to mask off the door that you painted with masking paper and tape, but heating the paint so that it expands off the brick will help you get more of it off.

I am a historic buildings conservator and I just want to clear something up. NEVER NEVER NEVER sand blast or use abrasives on brick! Bricks have what is referred to as a "fire skin" a less porous skin on the exterior surfaces. This makes the inside of the brick more absorbent than the exterior. Once sanded away you expose the more porous internal clay body. Making your brick more susceptible to decay and weathering, eventually requiring total replacement of the brick and the surrounding material. So to answer your question, a Ph neutral (Ph 7--Ph can be found on the MSDS available online or with the product) paint stripper is your best bet (an acid stripper can etch the surface of the brick). Ones that I generally suggest testing is Peel Away 7 or Smart Strip.

I love the colour of that door. Leave it as it is and save your time, energy and money for other things.

Use Peel-Away 7 or Citristrip. Both easy and not a lot of elbow grease involved for such a small mishap.
Here's a big project we did with it:

Another buildings conservator here, and please please please do NOT sand or use other abrasives your brick. Try a mild paint remover like soy gel (you can buy it on amazon in small quantities) or peel away 7. Test it on a small area first to make sure it won't do any thing bad to the brick. And make sure you use painter's tape on your finished door to protect it from the paint remover!

Though NOT a building conservator, my gut told me not to sand brick. I guess it would be akin to sanding a ceramic vase (from what Conservator #1 implied)-- you'd have sand the outside 'glaze' right off, in order to get rid if the paint.

well, at least u shouldn't feel that bad about it since the peach-painters did it too :)
