How do I spray paint (or otherwise best paint) furniture in my apartment without dying or destroying the apartment? I have a sliding glass door in my living room, so ventilation could hypothetically be about as good as it gets without no longer being strictly indoors.
Oh, and the furniture has metal, plastic, and painted wood parts, so fuck if I even know what paint will stick to it.
If you can't answer this one don't feel bad; I've been mulling over it for like half a decade and never got around to figuring it out properly.
Water based acrylic paint is good to keep you from dying. The smell of it is gone very soon, and it dries really quick too. (You can often apply a second layer an hour after you put on the first layer, with acrylic paint) There are primers to put on plastic, before you apply the layer of paint you want. Those primers do exist in acrylic versions too. I never painted on plastic, but apparently it can be done without a problem.
Water based acrylic paint can be used on top of a terpentine based alkyd paint, but not the other way around. So if you want to paint stuff that has been painted before, water based acrylic paint may be the way to go.
I never used spray paint, just a roller or a paint brush. Old newspapers on the floor kept my environment free from paint. Ex of mine always uses spray paint. Old newspapers and painters tape are what he uses. He uses aerosol-cans, and sprays from not too far a distance. His house is free of paint stains. And he has painted most of his furniture by now.
Before you start to paint it is important to get what you want to paint really clean, especially clean from fat. So, using a good fat removing detergent, or ammonia to clean first. And sanding is important too. It makes it easier for the paint to attach to where you want it.
If you only want to paint parts of your furniture, covering what you do not want to paint with newspapers or plastic and painter-tape will give you good edges. If you do use painter tape, make sure to remove it after a day or two at the most. Then it still goes really easy. After that it will get more and more attached to where you stuck it on. After a few weeks it may be almost impossible to remove it without lots of hassle.
If you have never painted before, searching some youtubes on painting techniques may be helpful. Some DIY chains do provide youtube information on almost everything.
