Once a decorative concrete floor is finished the best way of keeping it looking great it is to seal and protect its surface. Sealants and coatings are also used for other reasons.
Reasons for using concrete sealers.
Sealants are usually included in the installation scope of work similar to a hardwood floor installation, but any ongoing maintenance is rarely included.
Concrete sealants and finishes can add a matte, satin, low or high gloss shine to floors. They can bring out the beautiful colors in the floor as well as add a protective barrier that allows the floor to be maintained and looking its best for a very long time.
