Cracked resin (solid surface) sinks should be repaired right away to prevent leaks. Cracks can also spread out and further damage the sink. You may be able to use a two-part epoxy to fix some cracks. Solid surface repair kits are also available, but some deep cracks require a professional to fix the damage. Two-part epoxy or repair kits can be bought online or at some local countertop shops. The repair kits come in a variety of colours, so your sink should look almost new when you are done.

Put on all protective gear.
Clean the cracked area of the solid surface sink with a degreaser and clean rags. The sink must be free of all dirt, grime, soap scum for the resin repair to set properly.
Place 400 grit sandpaper into the sanding orbiter. Sand the area, first with the 400 grit sandpaper; repeat the process with 240 grit and then 120 grit sandpaper. Vacuum up all loose debris. Clean the area again with degreaser.
Cut off the end of the two-part epoxy tube. Squeeze the plunger until an even amount of hardener and catalyst comes out. Place this epoxy onto a small piece of cardboard or plastic. Mix the two epoxy components together, using a small stir stick.
Apply the epoxy to the cracked area. Work it in place, using the stir stick, until the crack is full and even on the top. Let it dry overnight.
Buff out the repaired area, using the orbiter sander, a buffing wheel and buffing compound. Let it dry for several hours.
Two-Part Epoxy Resin Sink Repair
Follow Steps 1 to 3, in Section 1 (above).
Separate the components in the kit. The kit will include a bonding agent, stir stick, small container, catalyst, spreader tool, colour match paint and detail brush.
Apply the bonding agent to the cracked area. You may have to brush it on; some kits have a spray can version. Let it dry several hours in a well-ventilated area.
Apply the catalyst, using the spreader tool or spray it on if applicable. Let it dry for several more hours.
Test the paint you believe to be the best match by applying a small amount to the sink area. If you need to adjust the colour, mix in some white paint. Apply with the fine, detail brush. Let it dry overnight.
