We are having a room with high walls repainted in a deep color. The
same wall has a typical return-air grille (24 x 24") with adjustable
vanes that has the usual factory-baked enamel, off-white color. We
wish to repaint the grille, so that it blends into the wall color,
rather than standing out in stark contrast.
It would seem that using an enamel or gloss paint is necessary, so the
grille may be cleaned periodically. Would it be best to use a primer?
Should the grille be sanded first? To achieve a smooth finish, should
the grille be sprayed?
What is the best way to do this job?
Any advice appreciated.
As I've been working my way through the house painting and fixing I've
tackled each air-grille as I've come to it. My experience may not apply
directly to your situation since mine are retrofitted into the ceiling
and my ceilings are mostly pure white. I've had perfect adhesion and
coverage by placing the grille into the dishwasher and running through a
normal wash/hot-dry cycle to remove all oils and dust and then I've
primed and painted the grilles using standard spray can enamels.
It is possible to obtain custom can spray paints or at least it used to
be so that might be one way to tackle your situation.
I remove them, clean them and then brush on the same paint that is
on the walls. They all look good to me.
Agreed! If they are shiney sand lightly for better painy adhesion.
running thru dishwasher after sanding a excellent idea
I would use a spray paint in a semi-gloss. It need not be a precise match
I used regular wall paint to paint my registers. At first they looked OK, at
best. After a few years they looked crummy and made the rooms look old. I
bought new grilles. The difference is like day and night, although the new
registers are white and the walls are of-white.
I agree with the methods of those who replied but I take it one step
further. I "bake" any metal I paint. I use the BBQ grill and bake for
one hour on most items. Baking the paint makes it adheres much better,
eliminates future chips and flakes and holds its' luster much longer.
