Can you spray paint ceiling fan blades.
Take the metal arms and the bottom plate outside to spray paint.
Painting the ceiling blades.
Clean the fan blades arms and the brass bottom cover well with a damp rag and some multi purpose spray cleaner if necessary.
Apply multiple coats until you ve achieved the coverage you want.
Spray one to two coats of kilz primer onto the fan parts.
When the blade s top side is almost dry turn it over to paint the underside.
Of course now i recommend taking the fan down and outside to spray the parts and then reinstall.
I would use a primer first if you are going from dark blades to white.
The paint has primer in it seems to stick well without sanding and i was afraid it would just make scratches that would show through the paint.
You should re assemble the fan unit only when the fan blades have completely dried.
Spray the fan blades and hardware pieces with a thin even coat of primer.
You could also use a can of spray paint to paint the blades.
After the primer coat then use satin or semi gloss on the blades.
Apply several thin coasts allowing each coat to dry before applying the next coat.
For this video we used an enamel spray paint with primer.
But i did not sand the brass.
Let the primer dry.
Shake the spray can thoroughly before use.
