Is your garage door dingy and dirty? Did you try to wash it and still didn’t get the result you were looking for? It might be time to repaint.
If you have steel garage doors, you are in luck. Repainting steel can be easy as one, two, three. Simply, follow these five best practices and assure your doors look great now and into the future.

If your door was installed sometime in the last two years, it is likely that the surface will have a layer of factory-applied wax. You must remove this layer in order for the paint to adhere well. To remove this wax, lightly scuff the surface with a GRAY (not green) 3M synthetic steel wool pad saturated with soapy water. Wipe and rinse clean with water only. Then perform an adhesion test.
If the adhesion test results are poor, do not proceed. Contact Cressy Door and Fireplace to discuss options or alternative coatings.
After properly preparing your garage doors and confirming adhesion tests, paint the doors within 24 hours. Use high-quality exterior latex house paint. Do not use oil-based alkyd house paint on top of factory-applied finishes. Follow these rules:
