Whether you want to touch up old, existing paint or just change the colour of the paint that came with the house, it is not a difficult task to paint your sink or toilet. As long as you take the necessary steps to remove the existing paint and prepare the surface, your paint job will turn out to be as good as a professional's. When painting any type of surface in an enclosed space, always air out the space so that you are not exposed to the fumes for an extended amount of time.
Clean the surface of the sink or toilet with chemical cleaners to remove dirt and grime from the area. Make sure that you rinse thoroughly and dry off the area completely once it is clean.
Sand the surface of the sink or toilet with a palm sander to allow the surface to become rough. This makes it easier for the paint to bond to the surface.
Apply chemical adhesive, or a bonding agent, to the surface using a spray bottle, cheesecloth or paper towel and allow the chemical adhesive to dry for five minutes.
Prepare the primer according to the instructions on the label and pour it into the spray paint gun.
Test the spray gun on a separate surface to ensure that it is working properly before applying it to the surface of your sink or toilet.
Spray the surface of the sink or toilet by moving in a back and forth movement to ensure even coverage for a total of two coats of primer.
Release the trigger when you reach the end of the surface to prevent the primer from running and overspraying an area. Allow 30 minutes to dry before applying the next layer.
Apply two to three layers of acrylic polymer with a gloss finish to the surface, allowing each layer to dry for 30 minutes before applying the next.
Wait before using the sink or toilet for 24 to 48 hours after applying the final coat of paint.
