Getting paint off concrete is usually a fairly easy task; however, some paints are quite stubborn and can take quite a bit of work to remove. It’s best to use the right methods from the beginning to make sure you don’t have to put in too much elbow grease.
Steps for removing paint from concrete:
1) Begin by scraping as much of the paint off as possible using a plastic pry bar. Any flaking left on your surface will come back up with standard pressure washing later on. If you’re dealing with graffiti or another highly sprayed area, consider investing in an inexpensive flat-head shovel for more thorough removal efforts… just be careful not to damage underlying patches below!
2) Next, rent yourself a pressure washer and a long, thin scrub pad to go along with it.
3) Soap up the concrete around the paint spots as thoroughly as possible to get all of your work in one pass. These are just about always works better when dealing with an entire floor!
4) Finally, begin applying liberal pressure and scrubbing downwards across the surface you’re working on. Move slowly back and forth over each painted spot in small increments until it begins to disappear: be sure not to skip over any painted areas or you’ll have some re-work for later! Continue doing this until the whole area is clear of paint or almost so- then let it dry overnight before returning to the next step!
5) The hard part is over. Next, use a pressure washer to clean off all of the residual soap from your concrete surface. A regular high-pressure hose will often work fine for this step; however, using a higher output pressure washer can make the process go even faster and is worth considering if you’re dealing with a lot of concrete or trying to get particularly stubborn spots out!
6) At this point you should find that whatever paint remains on the ground has been totally removed by your efforts so far; however, in some cases, it may be necessary to repeat steps 2 through 5 again just once more so that there aren’t any remnants left behind. Again, pay special attention to areas where multiple layers of paint have built up over time since these are the areas that are most likely to need more work.
7) Finally, hose down your concrete again to remove any leftover soap and any lingering paint spots from the previous step; let this dry for a day or so and you’ll find your bare concrete floor is as clean as new!
You can hit it with a sander using fine-grit sandpaper (make sure you wear safety gear!) to make it shine up nicely if you’re feeling particularly ambitious after all of that effort!
Remember: whenever possible avoid using heavy coatings such as latex on concrete since these are much harder to remove in the future. If nothing else, be careful when applying waxes and oils- these may help keep your floors looking shiny but they’ll also make them much harder to clean in the future!
Remember, always use caution when pressure washing around your home. Avoid using extension cords and try to stay as far away from windows and doors as possible.
