Unlike waterproofing compounds that have to be heated in a kettle, Henry’s CM100 waterproofing is applied “cold” and cures in contact with moisture in the air. The nonflammable formula also has less volatile chemical content and no solvent odor, says the manufacturer. It can be used for single-coat waterproofing on wall surfaces or as part of a high-build reinforced system on roofs and walls. A 4.75-gallon bucket costs $170. Henry, 800/486-1278, henry.com.
