Rapid Set Self-Leveling Sealant was used to fill the expansion joints and cracks on the driveway to prevent air, debris, and moisture from getting into the joints. This will aesthetically improve the driveway and will make it easier to clean and maintain. Self-Leveling Sealant is long-lasting, provides excellent adhesion, and outlasts all traditional sealants. | CTS Cement Mfg Corp | Rapid Set
