If you have black gas or water pipes, or black piping in your bathroom, it's easy to paint it with another color that blends in with the surroundings or matches your décor. There's even a special paint called Stove Paint you can use safely for pipes that carry heat, such as hot water pipes or pipes from your oven.
Ventilate the area you will be painting. Open any available windows and doors.
Cover any areas you do not want to paint with drop cloths or plastic sheeting. Use painter's tape around any edges you can't cover with a drop cloth.
Shake the can or stir the paint in its container. Start at the highest point of the pipe and paint as you normally would, using enough paint to cover the black.
Allow the first coat of paint to dry and then apply a second coat if necessary. For some dark colors, all you will need is a first coat, but if you are painting a black pipe white or yellow or a similar light color, you may need two coats.
Let the pain dry fully before touching it or placing anything up against it. Remove the tape and drop cloths.
