ABSTRACT:
Improved sprayable roof coating systems which provide immediate waterproofing of a newly-sprayed latex-based ionic roof coating by applying to the upper surface of such roof coating an ionic catalyst having a pH opposed to the pH of such roof coating, whereby such upper surface of such roof coating coagulates immediately to form a thin waterproof surface layer on such roof coating and the bottom portions of such roof coating are permitted to coagulate and bond to the underlying roof normally. Also, latex-based sprayable roof coating systems permitting use in roof mastics of recycled rubber and spray equipment for such systems which do not clog up when air spraying such recycled-rubber-containing roof mastics.
