Larger grinders are designed for the operator to walk behind, pushing the grinder slowly along the floor. Once the grinder makes one pass, the operator slowly moves it backward, moving it from side to side to ensure even grinding. The next pass overlaps the first by about half. Grinding the floor can take many passes, and depending upon how smooth you want to make it, can require the user to progressively change the grinding disk from a low, coarse grit to a high one. Many changes are necessary for a polished floor, but since you will be applying a coating rather than polishing, this is unlikely to be necessary. A hand grinder has a smaller diameter and is suitable for grinding close to the wall or for smoothing down bumpy areas before you use the large grinder. It is also possible to simply use a hand grinder for the entire project, though this may take more time.


Grinding concrete is an integral part of floor refurbishing. Many experienced floorers will use a concrete floor grinder this year to update a garage, renovate a basement, or

refinish a patio. While it may seem like just one concrete floor grinder will do, each tool is designed for specific jobs and processes.

How can you know which grinder to choose? With so many options, both experts and DIYers may struggle to find the best tool for the job at hand. No one likes to pay someone else

to fix their mistake, so it's crucial to get the guidance you need and pick the right grinder the first time.

Whether you're prepping concrete for staining, changing a flooring's exposure, or leveling a floor after repairing cracks, you'll need a concrete grinder to finish the job.

Here's everything you need to know to get the best concrete floor grinder for your business.
