Getting Paint Off A Cement Block Wall

I have real cinder block and not concrete block. You can actually see the steel slag cinders in the blocks. I've tried removing the paint using some of the best paint strippers out there without much luck: Peel Away 1, Peel Away 7, Smart Strip, Smart Strip Pro, and Lightning Strip. I tried 3000 psi pressure washing with very poor results.

Getting paint off a cement block wall. My name is Christine and I work in the paint department at Home Depot. Unfortunately, there isn't a quick and easy solution to removing paint from a cinder block wall. :( If you are committed to removing the paint, using a stripper specifically for removing paint from concrete is going to be the best. What do I do if the sand and cement in the joints of a block wall is rubbing off when I am trying to paint over the wall? Community Answer. Clean it the best you can, let it dry, and then put on a sealer. Let it sit to dry for a few days, then paint it. You can then put on another sealer made for after painting. Get a good scraper, some sand paper and a wire brush or a grinder "depending how much paint you want to take off". Remove all the loose paint and clean it with 50/50 bleach water. I would suggest you get a two part epoxy and go over whats there. If you want to go back to concrete, get you lots of paint stripper..."nasty & expensive job". If there is a cinder block wall construction around your home you may, unfortunately, wake up to find graffiti sprayed on the wall. Depending on where you live, city ordinances will state the specific time period you have to remove the graffiti.

If you’re removing paint from an interior brick wall, then at a minimum you’ll want to use a tarp to collect dust, paint flakes, small debris, etc., that will fall during this process. Also, a tarp or protective plastic can provide an extra layer of protection for floors, trim, etc., that are in the working space. The procedure for stripping cinder block and masonry walls is virtually the same as that for stripping paint from any material at the beginning of the job, but because cinder block is so porous, the end of the job -- the part where you remove the paint residue -- can be difficult. You'll probably ultimately have to use a power washer, but since most of the paint is gone, you won't have to. STEP 3: Remove paint stripper residue. For this stage of the job, so long as you’re working on a compact concrete patch, you can probably get by with a wire scrub brush or a paint scraper. Wherever the strips leave behind either compound or paint, use the trowel to flake off as much residue as possible. If the trowel doesn’t cut it, scrub with a stiff-bristled brush and rinse with.

On top of that coating, 2 layers of latex paint (different colors). In many places it's possible to pull off large strips of the paint & white stuff right off the wall where it has bubbled away from the block. In other places the latex paint comes off with a paint scraper, but not nearly as easily. Peeling does not always remove the pasty white. Scrape it Off. The most common way to remove paint is by scraping it off, and the same is true for concrete walls. Before starting, lay a cloth on the floor beneath the area you will be working on so that the flaking paint can be easily removed later on. Then wipe the wall with a soft cloth to remove any loose paint or dirt before starting. Removing old paint off basement walls is a time-consuming effort. Basement walls present a challenge because the cement walls are porous, and this makes paint removal difficult. The temptation is to scrape all the loose paint off and then repaint the walls. This is one option. The chalky white substance so often found on old brick, cement or cinder block walls is efflorescence. It's an alkaline substance composed of salts and minerals from the concrete itself in.

Removing old paint from a wall can be a time-consuming but immensely rewarding task. Stripping away the old paint is essential before you repaint the wall. If you don't bother, the paint will not stick properly, and it will soon begin to flake off. New unpainted concrete block walls need to have all dirt and loose mortar removed prior to priming. Painted walls will need all loose and peeling paint removed. Lift off the peeling paint with a stiff putty knife or paint scraper. Then scrub the area with a wire brush. To remove paint from drywalls, start by cleaning the wall with soap and hot water to remove any dirt or markings from the paint. Then, use a sanding block or sander to rub away the unwanted pain. If you want to strip the paint off completely, as opposed to painting over it, you can use a paint scraper to peel off any remaining paint. The interior paint is getting blown off the walls by moisture, and the exterior is peeling in a number of areas. I've already told them that I think they need to have the roof checked (I suspect the moisture is coming in from the top), but beyond that, I'm looking to pick people's brains about the best way to approach recoating the exterior.
