Why Is My Garage Door Paint Peeling? [Solved]

Peeling paint on steel garage doors is often caused by paint being applied to the metal surface prior to it being sanded or scoured. Steel is a non-porous material that does not absorb paint like wood does and it will need to be lightly roughened in order to make microscopic grooves to which the paint adheres.
