More Information for PrepMaster Floor Grinding Machine

If you’re a surface preparation contractor and have a large concrete or stone project, you know the importance of having the right grinder on the job. Keeping floors functional, attractive, and safe are critical to any project.

Floor grinders are manufactured in a variety of power options. Like most equipment, there are pros and cons to propane verses electric. Many projects now demand clean energy, which reduces emissions and air born contaminants while others require the speed and muscle of a propane grinder.  Propane floor grinders need  added attention to maintenance however electric grinders require a constant source of electric power. While added power is ideal for grinding flaws out of damaged concrete, you also need to consider maneuverability, versatility, and grinding width.

The 3038 is a versatile, powerful floor grinder that you can trust to get the job done right the first time.
