  • Patent number: 8716370
    Abstract: A roof sloping compound for creating an auxiliary slope over a wide variety of roof membranes and substrates. The compound includes a dry mixture of aggregate, cement and a redispersible dry polymer adapted to be mixed with water to define a substantially self-leveling consistency enabling the compound to be readily screeded into place in a desired thickness. The aggregate comprises dolomite or limestone and the redispersible dry polymer can comprise a binder based on a copolymer of ethylene vinyl acetate. In a lightweight embodiment of the compound, the aggregate includes lightweight fillers comprising perlite and low density glass granules and a superplasticizer is added to the dry mixture to reduce water demand.
