Cutting Industrial Epoxy and Polyurethane Floor Overlays
Direct Answer: Sawing expansion joints through industrial epoxy and polyurethane floor toppings requires hard-bond diamond blades equipped with aggressive keyhole gullets and continuous water cooling. Water prevents the polymer coating from melting and smearing inside the kerf, while keyhole gullets eject sticky coating swarf cleanly.

Frequently Asked Questions
Why do epoxy floor coatings gum up dry diamond blades?
Dry friction heats epoxy above its melting point (~200 deg F), turning it into a sticky liquid that coats diamond segments and stops cutting.
