When dealing with concrete, the finishing process can make all the difference–and when it comes to sanding concrete, sealing is essential. It gives the concrete a smooth, finished look and provides a protective barrier that helps guard against regular wear and tear, spills, and stains. However, this doesn’t mean you can just slap on any sealant and call it a day; for best results, apply one to two coats of quality concrete sealant after completing the sanding process. Doing so will ensure that your newly sanded surface looks great and stands strong for years to come.
