# How to Paint Over a Glazed CMU Wall
If you have a glazed CMU wall, then you have a wall that is made of concrete cinder blocks. This wall is known as a "concrete masonry wall." You can paint CMU walls as long as you sufficiently clean them first and paint them with primer. Because concrete is porous, it requires primer and top coat made specifically for concrete.
