Rent surface prep and floor care equipment from TRULAND at Wauseon, OH and Angola, IN. Grinders, sanders, strippers, scrubbers and buffers.
In nearly every case, yes. Concrete has a sealed surface layer and often contamination on top of it, and coatings applied over that peel. Grinding opens the surface so the coating can bond, and coating manufacturers specify a surface profile you need to hit. Coating failure is almost always a prep failure rather than a product failure. Tell us what you are putting down and we will match the machine and tooling to the profile it needs.
Getting a floor ready to take a coating, and keeping a finished floor clean. On the prep side, that means grinding concrete to open the surface so epoxy or sealer actually bonds, removing old paint, mastic, glue or coatings, smoothing high spots and trowel marks, and sanding wood floors back to bare.
On the care side, it is scrubbing, stripping and buffing finished floors in shops, warehouses, stores and facilities, where the job is maintenance rather than renovation.
The two get confused, and the difference matters. A coating that fails almost always fails because the surface underneath was not prepared, not because the product was wrong.
Concrete grinding, wood sanding and coating removal are different jobs with different machines and different consumables. Diamond tooling for concrete comes in grits and bonds, and the correct bond depends on how hard the concrete is. A hard bond on hard concrete glazes and stops cutting. A soft bond on soft concrete wears out fast.
For removal work, the question is what is on the floor and how thick. Thin paint, heavy epoxy, carpet glue, tile mastic and thin-set all behave differently, and there are cases where a stripper or a shot blaster is the right tool rather than a grinder.
Tell us the surface, what is on it, the square footage, and what you are putting down afterward. Coating manufacturers specify a surface profile, and hitting that profile is the entire point of the prep step.
Grinding concrete dry without dust collection fills a building with silica dust in minutes and creates a serious health hazard along with an enormous cleanup. Plan for dust collection or wet work from the start and treat it as part of the job, not an accessory.
Contain the area. Dust migrates through a building through doorways, stairwells and HVAC returns, and it lands on everything. Seal openings and shut down air handling that pulls from the work area.
Check your power. Larger grinders and floor machines draw more than a standard household circuit provides, and some require specific voltage or a generator. Confirm what is available at the site before pickup rather than discovering it on the morning of the job.
Respiratory protection is required for concrete work. Silica exposure causes permanent lung damage over time and there is no way to undo it. Use the dust control the equipment is designed for and wear appropriate protection even with collection running.
These machines pull. A grinder or a floor machine will walk sideways when the head loads up, and it can take a wall or your ankles with it. Start slow, keep a firm grip, and learn how the machine behaves in an open area before you work near anything you care about.
Overlap your passes and keep the machine moving. Holding a grinder or sander in one place gouges the floor, and gouges take far longer to fix than they took to make.

It depends on the hardness of the concrete and what you are removing. Diamond tooling comes in grits and in bonds, and the bond has to suit the concrete. A hard bond on hard concrete glazes over and quits cutting, while a soft bond on soft concrete wears out quickly. Removing heavy epoxy, carpet glue or mastic is different again and sometimes calls for a different machine entirely. Describe the floor when you call.
You should not. Dry grinding fills a building with silica dust within minutes, which is a permanent lung hazard, and the cleanup afterward is enormous because dust travels through doorways, stairwells and HVAC returns. Plan for dust collection or wet work from the start, seal off the area, shut down air handling that pulls from the space, and wear respiratory protection even with collection running.
More than a standard household circuit in many cases. Larger grinders and floor machines require specific voltage and amperage, and some jobs need a generator if the site does not have it. Confirm what power is actually available at the site before you pick the machine up, because finding out on the morning of the job costs you the day.
