How do you keep paint from peeling off concrete?
Tape a piece of relatively thick, clear plastic, such as a three-inch square cut from a reclosable plastic bag, to an area with no paint. If moisture droplets appear over the next day, you’ll need to strip off all the paint and switch to a coating that resists hydrostatic pressure.
What causes paint to peel off concrete?
Concrete contains alkali which may be drawn to the surface by water. When the water evaporates the alkali leave a crystallized substance called efflorescence, which pushes against the paint film and causes peeling. If there is no moisture barrier under the concrete, moisture can easily seep through.
Should I PVA garage floor before painting?
