Our countertop heaters are specifically designed to gently raise the temperature of the heated area an additional 20 to 25 degrees Fahrenheit.

The peel test strip (included) can be used to evaluate whether the surface of the stone will need the prep coating.

Smooth granite and any stone with a mesh backing will most likely not need the kit.
