Renovating Your Home? Here's a Description of a Few Concrete Grinders

When it comes to concrete grinders for home use, single head ones are great because they aren't terribly expensive, have a decent amount of power, and are relatively simple to handle. However, they can and do leave behind "tool marks" or grinding shoulders, which look like rings after you apply the sealant. Wider grinding wheels don't leave so many grinding shoulders like the smaller ones do, but they don't get all the way to the bottom of the depressions. Double head grinders can do more work in less time, so they're quicker than their single head counterparts, but they're heavier and they use up more electricity in the process.

If you're worried about tool marks, planetary concrete grinders minimize this problem with four grinding heads. These grinders are actually pretty smooth to handle and don't require a whole lot of force to keep under control. If you want your concrete to be smooth than this is the grinder for you.

Another concrete grinder that's great for polished concrete floors is the 8 wheel flat type. These machines are designed for easy replacement of the grinding wheels, and maintenance on these machines is much easier. These devices are pretty easy to handle as well, like the planetary models.

Concrete grinders need a decent size dust collector in order to keep foreign materials from getting airborne. Clean air is important in your work space, so make sure you have one of these devices attached when you're doing your grinding.
