I’ve been in the epoxy flooring business for 3 years and have spent a fortune on grinding machines and tooling. NOTHING I have used works as well as the Prep/Master system. My employees couldn’t get rid of their smiles with our new machine. Life just got a lot easier!

Testimonials List

The main reason I use the Prep/Master for my flooring prep work is due to its incredible durability and low level of maintenance. 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
What we were pleased to find is that the diamonds worked exactly as advertised. We did not have issues with scratch marks between steps – productivity and diamond life were spot on. I will use the system again because of its predictable results and fast turnaround time.

I am writing to compliment your professional support and the great results of STI tools used to complete our project of prestige — The National Art Gallery Singapore (NAG). We have accomplished our mission for this project and got more projects from the same consultants thereafter.

“We use our Prep/Master grinders 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
I am amazed! I have done 3,000m2 (30,000SF) and the TPS #1 and TPS #2 still have life left! I will never use any other diamond for terrazzo ever again.
Silas Katonyera
The customers who see my floor say they have never seen polished concrete look so good without a guard on top of it. Because of the EGT System, I now need to redo my other polished areas because they do not have even half the shine!
