polish existing concrete floor

There are a number of factors that can affect whether or not polished concrete cracks, including the mix design, the placement and finishing procedures, and the inherent properties of the concrete itself. However, with proper care and attention to detail, it is possible to create a beautifully polished concrete floor that will last for many years without cracking.

One of the most important things to keep in mind when trying to avoid cracks in polished concrete is the mix design. The ratio of cement to aggregate should be carefully considered, as too much cement can make the concrete susceptible to shrinkage cracking. The aggregate size and type should also be taken into account, as larger aggregates can help reduce cracking potential.
 

Generally speaking, polished concrete is cheaper than tiling. The initial costs of polished concrete are lower because you don't need to purchase tiles or hire a tile installer. Furthermore, polished concrete is easier to maintain and clean than tile floors since there are no grout lines for dirt and debris to accumulate in. In the long run, polished concrete will likely save you money on flooring costs.

Sealing polished concrete is not necessary, but it can help to protect the surface and increase its shine. A sealer will also make it easier to clean and less susceptible to staining. Although there are many different sealers available, it's important to select one that is compatible with polished concrete.
