Painting Concrete Basement Walls
Before you actually begin to paint, there are a few steps to take. The walls must be clean and clear from any debris. Also, it is recommended that you perform a technique called acid etching before painting concrete basement walls. If you?re painting concrete basement walls that already have been painted, you won?t have to do the acid etching, unless there are bare or peeling spots in the old paint.
When preparing your solution for acid etching you must follow the directions precisely. The acid can be caustic, so make sure to wear protective gloves and other gear. In order for the paint to adhere, the powder must be completely removed. By following the etching directions correctly, your canvas should be the texture of number one or number two sandpaper. When the concrete is chemically neutral and dry, you can begin work on painting concrete basement walls and make sure there is proper ventilation for the paint fumes.
