Rave Reviews about the EGT Diamond System

logo TCE"The customers that walk in and see my floor say they have never seen polished concrete look so good without a guard on top of it. Some of them don't believe that it's not coated with a Guard or an epoxy clear coat.

Because of the EGT System, I now need to redo my other polished areas (done with old tool technology) because they do not have even half the shine!"

~ Gus Valdez, Owner of Concrete & Terrazzo Equipment, Chicago IL

logo Master Craft Floors"Master Craft Floors has been using STI equipment and tooling for many years without issue. The equipment is bulletproof – to date we’ve had no equipment problems on our job sites. As for STI Tooling, we believe it’s the best on the market. Master Craft has tried other distributors but we have always reverted back to STI with no plans to change.

Substrate Technology’s diamond system makes for easy installation - the number coding on the back of the diamonds provides clear direction for our installers throughout the process. After running the whole system (steps #0 tool through #8 pad), our results are exceptional!

Master Craft has had great success with the new EGT System; we like the heavier concentrated diamonds for the initial cuts. We feel the EGT System is going to be a great fit for us and will be our diamonds of choice for future projects.

Thank you STI for the great equipment and products!"
