Polished concrete floors are a beautiful addition to your home, but like any other type of concrete, they can develop cracks as the concrete shrinks. Fortunately, concrete floor crack repair is easy; however, when the concrete is in your home, you want the repairs to be invisible. Here's how cracks in concrete flooring can be repaired.
Match The Filler Color
One problem with repairing cracks in sidewalks and driveways is that the repaired area is a different color and is noticeable. You can avoid this problem in your stained concrete floor by having repairs done when the cracks are tiny and by matching the color of the filler to the color of your floor. Concrete floors are painted in a variety of colors, and it's usually easy to find a matching color of filler. If not, a clear filler might be used.
Apply The Filler
Filler is used to fill chips, cracks, and other imperfections in concrete. It repairs the damage, and at the same time, it improves the appearance of the floor. Before work begins, you may want to determine the reason for the cracking, especially if the crack is large or appeared suddenly. Shrinking of the concrete as it cures is a common cause, but it's also possible the problem could be due to shifting of the slab due to foundation problems or soil shifting. Those more serious problems might require further treatments beyond simply filling in the cracks or the cracks might return.
Polish The Surface
When filler is placed in a crack or hole, it is packed in from bottom to top. This leaves too much on the surface that has to be removed. Removing it is easy by using a floor polisher with the right grit pad that buffs out the raised portion of filler over the repairs so that the surface is smooth. A good time to repair cracks routinely is right before the floor needs to be polished again to restore the shine. Once the filler is in place and the floor is buffed and polished, the repairs will blend in and not be noticeable.
The best way to reduce the appearance of cracking is to make sure no mistakes are made during the installation process, so there's not much you can do as a homeowner to keep cracks from appearing. Instead, you can have them repaired by a professional when they arise, so your floors continue to look beautiful for many years to come.
