To remove paint from concrete can seem like a difficult task. Using a high pressure power washer will make the job much easier. This is only possible on exterior concrete surfaces, though. Using a chemical paint stripper is the most commonly used method of removing paint from concrete indoors. These chemicals are usually extremely caustic and require adequate ventilation. Some manufacturers have introduced new soy-based gel products which safely remove paint from concrete indoors and out. Available only through contractor supply stores and through online sources, these paint removers are said to be highly effective and completely non-toxic. They are also considerably less messy than regular paint removers due to the gel consistency.
