Whether you are removing glue layers or trip hazards, smoothing rough textures or repairing weather damage, our walk-behind concrete equipment rental options will suit your residential DIY jobs and large construction sites.

Our concrete scarifier rentals can remove your unwanted concrete quickly and efficiently, pummeling up to a quarter-inch of concrete in one pass.

FAQs About Concrete Grinders & Planers

How much will a concrete grinder remove?

  • Concrete grinders vary in depth of grind depending on their size and how many heads the grinder has. Double-head grinders will remove more material in a single revolution compared to single-head grinders. Walk-behind concrete grinders will remove more material than handheld grinders. Dual-head walk-behind grinders can remove up to 1/2 inch in an hour of grinding. For more information, see the specifications for each model.

Can you cut concrete with a grinder?

  • A walk-behind grinder will remove material a fraction of an inch across large areas. If you need to cut into concrete, check out our concrete saws available to rent. Not sure what you need? Call United Rentals today at 833-548-9477.

Can you cut or grind concrete with an angle grinder?

  • Angle grinders were not designed to grind concrete, but contractors have used it for finishing work and cutting through tiles. In general, if you need to grind cement in a large area such as a garage, warehouse, sidewalk or parking lot, then walk-behind concrete grinders would be the most efficient equipment. We also have specially designed saws to cut through concrete.

What does a concrete scarifier do?

  • A concrete scarifier, otherwise known as a planer, is used for heavy-duty concrete removal. These machines have a series of wheels made of steel or tungsten. These wheels spin and pummel the ground until the concrete breaks up. They are typically used for removing trip hazards, creating grooves for slip-resistant sidewalks and leveling. United Rentals offers walk-behind scarifiers with optional vacuum attachments to help you with the cleanup. Because scarifiers use wheels, they leave a rough surface texture. A concrete grinder would be able to smooth this roughness and prepare the concrete for coating.

Should I rent a concrete grinder or scarifier?

Concrete grinders (sometimes called concrete sanders) remove material up to 1/8 of an inch below a concrete surface per pass. Rent a concrete grinder if you need to remove surface materials such as paint, epoxies, stains and other coatings. A concrete scarifier, aka concrete planer or milling machine, removes up to 1/4 of an inch per pass. It is often used to level concrete and asphalt, remove trip hazards on sidewalks, create sidewalk grooves and remove heavy-duty overlays and hard industrial coatings.

What type of concrete grinder should I rent?

Handheld or walk-behind grinder

Handheld concrete grinders are useful for getting into tight corners or preparing surfaces close to walls. A walk-behind grinder rental works well for projects that require more aggressive grinding, polishing or leveling.

Single disc, dual disc, planetary or edge grinder

Single disc grinders are the narrowest grinders, which makes them good for small spaces. They are best for small or residential jobs covering less than 1,000 square feet. Dual disc grinders are commercial grade machines good for jobs larger than 1,000 square feet. They come in electric models for indoor use and propane- and gas-powered models for outdoor use.

Planetary grinders, which have three discs, can be used for large grinding jobs but are more often used to polish concrete floors. Edge grinders are designed to work in the small spaces next to walls, which regular grinders can’t reach because of their dust shrouds.

What rpm do I need?

In low-rpm machines, the disc spins between 250 and 600 times per minute. They are best for surface cleaning. Turbo grinders have discs that spin at between 1,000 and 1,500 rpm and are better when you need to cut deeper into the concrete and get to exposed aggregate. A turbo grinder is more of a pro tool, not for the average do-it-yourselfer.

What type of grinding wheel do I need?

Silicon carbide grinding wheels remove flaking paint, adhesive and foam carpet backing. Diamond grinding wheels can remove stains in concrete and can also handle tougher jobs.

What bond do I need for my diamond wheel?

“Bond” refers to how the diamond crystals are held in the wheel. Choose soft, medium or hard depending on the abrasiveness of the concrete you’re working with. Choose a hard-bond diamond accessory for the most abrasive concrete (concrete with high sand content). Concrete with a lot of river rock is less abrasive.

What grit do I need?

Grinding wheels are available in a range of grits. Lower grits are for more aggressive concrete removal. Medium grits are for general purpose work. Higher grits are for concrete polishing. When polishing concrete, start with a low grit (18 is the lowest) and work up to a high grit (over 200).
