Refinishing a poured concrete floor isn't that different from refinishing any other type of floor. You just have to have the right equipment. While sanders are typically used for wood floors, concrete floors require a concrete grinder to slough off any old finish. Grinding sounds harsh, but it's not. Concrete grinders are a very adaptable tool for readying your floors for new paint or new finish. The process is a lot of work, but it is surprisingly gentle.
What You Need To Know Before Tackling Concrete Grinding
Whether you're wanting to refinish your poured concrete garage floor or your kitchen floor, you're likely to have some basic questions if you're a novice:
Where can concrete grinders be rented?
You can rent grinders at any tool rental or home improvement store. You can usually rent a push-behind grinder for a 4-hour minimum. You can also rent grinders by the day, week, or month. Get the lightest unit possible for the job. As a rule, the heavier the grinder, the more abrasive it will be on your floor.
What kind of grinding pad do you use?
Concrete grinders come in varying sizes depending on the job. A common residential garage or kitchen floor job will use a push-behind grinder or a hand grinder. The walk-behind grinders will have about a foot's swath over the floor. They also use smaller pads for your prep work. Residential concrete grinding pads are best for light jobs that require a light abrading. They will take off about 1/16 in. or so of old epoxy and remove old paint, scuffs, and the like from your floors. You can also rent an attachment that catches the dust as you grind.
Will a grinder cause ridges in the concrete? What if the floor has a decorative design?
Most pads come in tungsten carbide or diamond attachments. If the surface you want to use the grinder for can be cut with a knife, use the tungsten pads. If not, use the diamond pads. You won't get grooves in your concrete design.
You can hire a professional contractor if you don't feel comfortable doing it yourself. But if you've previously used a sander in your home, you won't have any troubles using a concrete grinder. It's the same principle. Guide or push the tool from behind, let the machine do the work, and use a hand-grinder where needed to completely prep your floor for refinishing.
