I just bought some standard latex paint to paint aluminum garage doors.
The woman at Home Depot made it a satin finish. Is that Ok to paint
an exterior garage door ? Is that standard ? Or should it have been
different such as eggshell or semi gloss ? Will satin last a long time
I live in Ottawa Canada, so the weather here goes from very cold to
Thanks all in advance.
It's your door to do with whatever you please.
Is that standard ?
NO. It is not. Most aluminum doors are unpainted. You could just
try giving it a good cleaning with a power washer.
Or should it have been
Not as long as High gloss enamel which is the longest lasting.
Perhaps you meant that most aluminum garage doors come pre-painted? I've
never seen an unpainted aluminum garage door. Even the metal service doors
come at least pre-primed. Paint does fade and otherwise become unsightly.
Latex paint will work just fine on aluminum. I wouldn't go any higher than
a satin sheen. Most people prefer either a flat or satin finish on the
exterior. Semi-gloss is just too shiny. Exceptions may include doors, but
rarely garage doors because they are so large.
It is rare to see gloss paint on the exterior of a house. In fact, it's
rare to see gloss paint anywhere on a house.
Just my two cents here, but I wouldn't paint aluminum garage doors with
latex. Maybe a top quality Acrylic Latex might work for a few years
(depending on the quality of the surface you're painting on) however if
it were MY garage door(s) I would first carefully prepare the surface
(thoroughly clean, lightly sand for adhesion) prime with a good alkyd
primer (Rustoleum works great) and then paint with a quality alkyd
(oil-based) or epoxy paint. I would spray the final coat for an even
finish. Aluminum is particularly difficult to paint because it is such
a good thermal conductor - it moves a lot with temperature variation
(expansion/contraction) so it needs a paint that really hangs on tight.

Don't paint them with latex, it will take 2 or 3 coats to cover it, and
you'll be disappointed with the results. I've have good luck painting metal
with Rust-X paint. The stuff is oil base, high solids and designed for
