Application

RJ-DN121 is an architectural mastic coating that can be used as a waterproofing coating in vertical, horizontal and roof applications to cover holes and minor cracks and to conceal surface irregularities. RJ-DN121 can be used in non-traffic horizontal and roof applications. Primerless adhesion has been attained on many substrates including: concrete, stucco, masonry, urethane foam, wood, copper, EIFS, aluminum and many painted surfaces. Adhesion should always be verified by testing a small area prior to the beginning of the project.
