Superb Reviews of the #0 & #00 Prep Tools

logo armorpoxy“We use our Prep/Masters almost daily under very harsh conditions for concrete prep work. We find they are built like tanks, and require very little maintenance, and run better than any other machine we have used.”

~ Daniel Blum, President, Prep-Crete Services, LLC

Stoncor logo"The main reason I use the Prep/Master for the majority of my flooring prep work is due to its incredible durability and low level of maintenance on a job site. It is by far the best piece of equipment for the removal of high build coatings and membrane systems.”

~ Steven S. Williams, Field Support Manager, Stoncor
