Painting over powder coating in Yucaipa Ca

After completing the adhesion test  I posted in my previous article, we continued to do the necessary preparation that included, degreasing the complete surface, power washing and grinding the complete surface. The rust areas we ground to the bare steel. We applied 1 heavy coat of Vista Paint Metal Prime, then applied 2 coats of Vista Paint Protec Alkyd Emulsion Semi Gloss. Below is the video of the process of painting over powder coating. I will be doing a follow up video of a adhesion test after a 3 week cure period.

Vista Paint Protec Metal Primer Adhesion Test Over Powder Coating

We were contracted to repaint the steel on a amphitheater at the Yucaipa Community Park. The steel structure was originally coated with a powder coating. Many have questioned if it is possible if a paint can adhere to the slick tough powder coating surface. The Video bellow shows a adhesion test with Vista Paint Protec Metal Prime over Powder Coating. We degreased, power washed and disk grind-ed the entire surface. The following day I applied Protec Metal Prime, letting it cure for 24 hours I then applied Red – Duck Tape Brand Duct Tape. The 1st test I applied the duct tape pressing firmly and removed, no primer lifted. The 2nd test was done this time letting the duct tape set for 19 hours, I pulled the tape, as you can see in video bellow it griped to the surface tightly. After pulling the duct tape off there was no appearance of the primer delaminating or pulling off with the duct tape.

With the right preparation and the right primer, it is possible to paint over a powder coating
