Expected Wear

Weather conditions, harsh cleaning methods using high-alkaline, acid or solvent-based cleaners will affect the sealers long term performance. Under normal conditions the sealer will last up to 2 years following correct maintenance. However in high traffic areas it is recommended to be reapplied every 6-12 months.
