Can Epoxy Be Installed Over Paint?
No. Paint must be mechanically removed before any real coating goes down. A coating installed over paint bonds to the paint, not the concrete.
Key points
- Old paint has to come off — grinding or shot-blasting
- Do not skip this step to save money
- The concrete underneath needs fresh preparation
