Remove Paint From Concrete Without Any Chemicals Using A Cheap Drill Attachment

Removing paint from concrete from a wall or a floor may seem like an impossible task. However, there is a quick and easy way that not only removes the paint almost like it was never there, but it doesn't require any chemicals. While one popular route to take with this type of project is a chemical stripper or acetone, these methods aren't always necessary. You can remove paint from concrete using a simple abrasive wire cup brush attached to your drill. It's an attachment, compatible with most drill types, that you can find at your local home improvement store or online, usually for less than $5 or $10. Commonly used to remove rust and prep metal surfaces, these attachments  can also strip painted concrete. Note that your specific method may need to be adjusted based on what type of paint is on your concrete, and how fresh or old it is.

If you're working in an enclosed space like a garage or basement, opting for a mechanical method like this to remove paint from your concrete may be preferable. Using a fume-heavy chemical product without proper ventilation can be hazardous, causing mild symptoms like skin irritation and dizziness to more severe symptoms like liver, kidney damage, and cancer. A mechanical method, like the wire cup brush, is inexpensive and requires zero harsh chemicals. All you need is some hot water and dish soap. The other beauty of this method is you can buy bundles of differently sized and shaped brushes for larger or smaller paint removal jobs.

Always wear protective gear, like a N-95 mask, gloves, and goggles, when removing paint, even without the usage of chemicals. Even if you aren't using a paint stripper, the dust from removed paint is still hazardous to breathe. 

First, clean your concrete floor or wall. Next, determine what type of paint you are removing and its age. Fresh paint is easier to remove than deeply embedded old paint, however, it won't work as well if the paint is still wet. If your paint is water-based or latex, it will most likely be easier to remove than oil-based paints or epoxy. With oil-based paints, chemical strippers will work better. To tell what type of paint you're dealing with, pour a bit of rubbing alcohol on a cotton swab. If the paint rubs off, it's most likely water-based.

With this mechanical method, it still helps to start with a liquid, but instead of a stripper or acetone, use dish soap and hot water. Pour this over the stain, and let it sit for a few minutes. Using your wire cup brush attachment, apply mild pressure and work your way across the concrete until paint-free. Finally, wipe up leftover water and paint residue. For large areas, like walls and foundations, this method can be used in concert with an angle grinder. Use the grinder for large surfaces, and the wire cup brush to clean up corners and spots with thick paint.
