So Can You Polish Damaged Concrete Floors?
If you already have damaged concrete floors, you may be wondering if Polishing them can bring them back to life. Damaged concrete floors may require repairs prior to polishing. Fortunately, minor chips, cracks, and surface damage often can be repaired, making polished concrete floors a viable opportunity to save significant money instead of replacing floors prematurely.
In some cases, you may only need a joint filler or caulk to take care of minor cracks. In other cases, you may need a rigid filler or a troweled mortar to repair large areas of the floor. After this step, the floor can be re-stained and re-polished as needed.
However, for concrete flooring systems that have sustained substantial damage down to the subfloor, the best option is usually a fresh start with new concrete before Polishing.
Concrete slabs that are of poor quality or have deteriorated over time may show excessive amounts of porosity. While these slabs can be Polished, it may be more expensive to achieve an aesthetically Polished Concrete finish.
