I have recently inherited my mother's childhood home. My great-grandfather built it in the 1950's. In the kitchen, there is a VERY large, pea green-colored, porcelain sink/counter. I would like to have a black sink, and would like to paint this one, if I can. I was reading up on it and someone suggested that I clean the sink, rub it with alcohol, apply a bonding agent, and then use a spray gun to paint it while wearing a ventilated mask. The only problem with that is that I do not want to have to spray paint it indoors and risk getting paint on my floors, walls, etc. However, it would be very difficult to get the fixture outside, because it does not fit through any doors and I am not sure how to disassemble it. Is there any way to paint it with a brush? And are there any other, less complicated methods you would recommend for this? Thanks.
Frankly, painting a sink is going to be problematic and even more so if you don't want to do it correctly. This is akin to refinishing a bath tub where you have a very smooth, very hard surface that you have to get paint to stick to. Typically that involves etching the surface to provide "tooth" and then using a high quality, expensive component "paint." It's a good solution in a bath tub that isn't subject to much physical abuse because bare feet are a lot softer than pot and pans.
The only way I know of to refinish your sink "in house" as a DIY would be to use a 2-part epoxy kit. These can be brushed or rolled on and at least 2 coats will be needed. These products do not come in black. Usually they are available in white and off-white colors like bone, biscuit and almond.
