Whats the difference between Lucas Standard Grade and Premium Grade cements and coatings?
Lucas Premium Grade roof cements and coatings are manufactured from higher softening point asphalts which causes them to cure faster, age more slowly, and resist oxididative cracking or alligatoring. Lucas Premium roof coatings can take roof traffic sooner and Lucas Premium roof cements will adhere to vertical surfaces without sagging, even when hot mopped. Lastly, Lucas Premium roof cements contain no unnecessary fillers like limestone dust (calcium carbonate), kaolin clay or slate flour. These fillers not only increase the sheer weight of the material but can also reduce long term performance.
