Over time concrete floors can become rough and gritty making even the simplest task of sweeping them almost an impossible task. Polishing your concrete floors gives a smooth surface while filling in the pores that harbor the dirt that is so difficult to clean. Polished concrete floors are much easier to maintain than rough concrete making it easier to wash and reducing overall stains.
There are several steps in polishing a concrete floor in order to make sure that the area is properly protected. An epoxy filler should be used to fill the joints and cracks, smoothed so that they are even with the floor, and then allowing proper drying time of the filler. After the filler has completely dried, a floor sander is used starting with a 40 grit sand paper to smooth down the roughest surfaces. Keep in mind that this is a very dusty job and wearing the proper dust mask is a must to preven inhalation of the particles. It is imperative that the floor be done in small sections to ensure proper sanding of the area, giving it optimal results.
Once the floor has been completly sanded with the 40 grit, an 80 grit followed by a 150 grit is used to give the floor a smooth appearance. A hand held sander is used for the corners as a floor sander does not properly reach those areas. After completion of this task, a liquid concrete hardner is filled into a pump sprayer and sprayed over the area in a fine mist and allowed to dry. After the liquid hardner has completly dried, the sanding process is then repeated, this time only with a finer grit sand paper.
Beginning with a 200 grit followed by a 400 grit, 800 grit, and then completed with a 3000 grit resin bond polishing pad. Again a hand held sander is used to get the corners that the floor machine does not reach. Your end result is a smooth concrete surface with a beautiful sheen that will make your garage or work space look great!
