Key properties usually include solids or residue content, viscosity range at application temperature, drying or cure time assumptions, adhesion to concrete or masonry, and recommended wet mil thickness per coat. Limits typically include minimum ambient temperature for curing, sensitivity to rain before full break, and maximum thickness per pass to avoid skinning and trapped water. Commercial users should also check VOC content, compatibility with primers and topcoats, and whether the product is intended for below grade dampproofing versus exposed roof service.
