I have five sets of aluminum sliding glass doors, each 6' wide that opens
into an interior courtyard. They are all bronze in color.
I am wondering if it's possible to paint them white?
If not, is it economical to order all new metal parts in white (basically
replace everything except the glass) or it's not worth it as the labor cost
to take apart reassemble is prohibitive and may be more than just replacing
the entire door?
Thanks in advance,
Do you have air and a spray gun? If not you are probably not going to
get a good result.
I have some experience painting aluminum boats. The real trick is the
primer. Go to a store that specializes in auto body paint and get the
2 part etching primer. This is nasty stuff, use a real respirartor
when you shoot it. This will cut through the oxide and give your paint
a good bite. Then shoot a couple coats of a polyurethane fortified
enamel on them and they will last for years. This still won't be as
nice as the powder coating you get from the factory but it is pretty
You will have to remove the hardware and take your time masking the
If you really have to do this with spray cans go to a boat store and
get zinc chromate primer and use the best enamel you can find in a
spray can. You should still be using a respirator, especially with
the zinc chromate. The other paints are not very heatthy either.
One fundamentally sound source of aluminum painting materials and
techniques is the aircraft industry. There are aircraft supply firms
that cater to amateurs typically members of the Experimental Aircraft
group. They have products that have been around for years. The
techniques can be quite demanding as the products are not your usual
idiot proof stuff meant for consumers, so don't expect a miracle with
little work. The end result ought to be very good, though... come to
think of it, most commercial aircraft look rather spiffy. HTH
