No, this product needs to be used on raw, unpolished, non-troweled concrete with a pH level between 7-9. The ChemLink M-1 Universal Structural Adhesive/Sealant is a good sealant for concrete cracks, however you would want to use the sealer prior to filling in the cracks. Please give one of our EcoAdvisors a call if you have any further questions or would like to discuss the specifics pertaining to your unique situation.
