When I had my interior painting done, after clearing out all of the furniture, myself, I also removed all of the wall plates in all the rooms to be painted. They were a beige color and probably yellowed. The wall was originally an off white and I had it painted a light-mid grey, so those wall plates would look terrible. After pricing replacement plates, switches and outlets (Would have been way too expensive to replace all of them), I decided to just paint all of the wall plates, switches and outlets (Used just a black gloss spray paint). I sprayed the plates outside and used a small brush on the switches and outlets. It worked out just fine and the blacks plates, etc compliment the wall color. It has been 7 years and the plates, switches, outlets are holding up well.
First off, the picture on the top THAT IS A HOME OWNERS PAINT JOB. If you here a school kid or your neighbor, this is what you get. I was a painting contractor for the better part of 40 years and never saw a PAINTER (even the worst painter) leave a mess like that. Maybe the electrician or the carpenter but, that is not something a painter could even do if they tried. House Painting Westminster Colorado
