Sink Form from Concrete Countertops

8 ft. long x 3-1/4" tall self-adhering flexible sink form. Will conform to most undermount sinks.

For double bowl sinks, the sink form can be notched with a utility knife to bridge the divider.

**Sink must have vertical walls. For tight radius corners, the sink form can be heated with a blow-dryer or heat gun to soften the plastic so it bends easier. If using a zero radius sink, the sink form will have to be cut into 4 pieces (one for each side of the sink).**
