Limitations:Do not leave excess or pooled material on the surface of the pavers. Do not use on polished or very smooth stone and on granite, slate and bluestone. Do not apply product to a damp surface. Always do a small test to ensure desired look and performance of the sealer. The minimum application temperature is 45 degrees F for 20 hours before and after the application. In hot, 90 degree F weather, working time is reduced so it is recommended that product be applied in cooler morning hours. Do not apply if rain is expected within 12 hours. In case of rain, wait until surface is completely dry before continuing.
