paint overhead garage doors

[billconner]

Building detached garage, will convert existing attached garage to living space. Studio for my wife but likely family room for a buyer.

I want to reuse existing. I think aluminum (it's dented) probably with foam core? But want them a different color. A good 100% acrylic seems likely best over very cleaned door, but what pitfalls should I beware of? Do I need to disassemble completely? Seems likely just to relocate.

Any tips appreciated. Thank you!

Not sure if I understand ? Is the door going to stay where it is or go to the new garage ? If its going to the new garage you have to take it apart anyway to move it so I would definitely paint it while its apart.

If its staying where it is then I wouldnt worry about taking it apart. When they painted the building that my business is in they sprayed all of the doors. Not sure what paint they used but its been about 5 years and they still look good. We didnt change colors so you dont have to worry about seeing a different color in the gaps when the door is open.

I had metal roll-up two doors painted in my prior CA home. Painter scuffed up door with 220 grit, cleaned with mineral spirits, and then painted on 3 coats using an airless sprayer. He used an alkyd paint from Sherwin-Williams that was made for metal. Doors looked better than new when he was done and held up great in the 2 years I stayed there.

When spraying, he un-hooked the doors from the openers and rolled them up to paint the bottom edges where they hinged as they pivoted into the horizontal position.

Painting a roll up garage door should no be a problem if a quality paint is applied in accordance with the manufacturers instructions. 80% of a god paint job is the preparation prior to the application of the paint.

I recommend a TSP hot water wash, let dry and coat with exterior latex. Personally I would avoid box store paint no matter whose name is attached and instead visit a paint store run by a manufacturer. There will be several price points and I generally think one gets what they pay for in paint.

CSR - yes - removing from existing garage and installing in new build garage. So paint both sides and all edges when apart. The embossed wood grain should disguise any brush strokes. May roll and then brush out.

I painted ours about 5 years ago. Went to Shewin Williams and they set me up. Holding up great. I would raise the door a little so it wasn't contacting the weatherstrip (top section) waited for it to dry the raise it some more, that way you do a better job with the seams. Otherwise they could dry together.

Couple times I've used "high end" paint store paint, it was ****.

Like recently took 4 coats to cover on a door, and really could use 1 or 2 more.
Only used Rhodda because I had the paint code saved from when the house was built.
Should have just gotten paint from the hardware store for ~30% less $$.

I would also look at what Rustoleum has available. Whatever you decide on for the paint I'd get primer from the same manufacturer.
