How to Refinish a Granite Sink
- 1). Scrub the granite sink clean with a trisodium phosphate cleanser, using a coarse plastic brush. Rinse the sink and wait for it to dry.
- 2). Abrade the granite sink to enhance surface adhesion by sanding it with 120-grit sandpaper. Load the sandpaper into a palm sander to ease the process. Scour the sink until it feels rough.
- 3). Cover surrounding surfaces with masking paper. Tape the edges of the paper down with a low-tack painter's tape.
- 4). Coat the clean granite sink with an acrylic spray primer. Hold the can 8 inches from the sink during the application process. Wait two hours for the primed granite sink to dry.
- 5). Coat the primed granite sink with an appliance epoxy spray paint. Apply the paint just as you did the primer. Wait six hours before using the sink.
