Limitations: Do not leave excess or pooled material on the surface of the pavers. Do not apply product to a damp surface. Always do a small test to ensure desired look and performance of the sealer. Do not use on very smooth or polished stone and granite, slate or bluestone. The minimum application temperature is 45 degrees F (7 degrees C) for 24 hours before and after the application. In warm, 90 degree F weather, working time is reduced so apply the product in the 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. Surface may slightly darken during excessive applications depending upon porosity of the pavers and application rate.
