While some spend hundreds replacing their old, tarnished sinks, frugal do-it-yourselfers know they can beautify their existing sink by adding a colorful, glossy finish. Unfortunately, when inexperienced amateurs try to refinish a sink, they end up with finish failure in the form of flaking. Learn the proper way to condition the sink for adequate adhesion, or flaking is bound to result.
Cleaning - Sinks tend to accumulate a lot of soap scum and grime. If you try to apply a new finish directly over these residues, poor adhesion will cause peeling. Scrub the sink with a trisodium phosphate cleanser before beginning the application process, or expect finish failure at some point in the future.
Abrasion - Sinks are too smooth to support a lasting finish. Combat this by scouring the sink with 100-grit sandpaper. Continue until the sink feels rough. Once the sink is thoroughly abraded, it will hold primer and enamel.
Masking - Cover all adjacent surfaces, using masking paper and painter's masking tape. The refinishing process will generate a lot of over spray. Be thorough, or stains may result.
Finishing - Even abraded sinks won't hold a new finish. Before you apply the final finish, add a light coat of acrylic spray primer. Once the primer has dried for three hours, apply a finish coat of acrylic spray enamel. For flawless results, hold an 8-inch space between the sink and spraying nozzle tip. Don't use the finished sink for at least three hours.
