Substrate Technology Inc. Surface Preparation Equipment for Sale

Based in Morris, Illinois, Substrate Technology Inc. was founded in 1995 by William “Bill” Jones. After spending 30 years as a contractor working in floor covering and preparation, he realized that there were no surface preparation systems that would improve and enhance productivity while offering durability and reliability. Instead, all the “systems” available required additional work by the end user to get the results they wanted.

Inspired by this challenge, Bill created a comprehensive system of floor grinding equipment and diamond tooling that reliably delivers professional, predictable results. From this, the Prep/Master brand of concrete floor grinders and diamond tooling systems were born. For a quarter of a century, contractors, flooring professionals, and concrete professionals have relied on our products knowing they offer unbeatable results and unmatched durability.

In our Prep/Master line of concrete floor grinders, we have all types of machines to help meet your needs. When you need a compact floor grinder for use in residential garages, basements, and small offices, the Prep/Master Junior is easy to use in these compact areas while still delivering the power and performance you expect. We also have large walk behind floor grinders that are powered by either electric or propane and for the largest spaces, including warehouses, consider our ride-on floor grinders that offer up to 44-inch working width and built-in S-curve motions for ideal results.

Using Substrate Technology Diamond Systems

While having a Prep/Master floor grinder is essential to getting the finish and polish you want, you need to pair it with the right tooling and diamond pads. The engineering and design team at Substrate Technology Inc. created diamond systems for all types of tasks, including buffing terrazzo, polishing stone and marble, and restoring and polishing concrete. With proper use and care, you’ll be amazed at the durability these pads offer as well as the incredible results they deliver.
