Abstract
A roof sealant composition and method for treating roof constructions is provided in which a roof sealant composition including from about 25 to 60% by weight recycled paint sludge is applied to a roof in a first coating followed by the application of a supportive mesh. A second coating of the sealant composition is applied as a top coat. Upon drying, a composite is formed which exhibits elongation of greater than 300% and a tensile strength of greater than 500 psi and provides resistance to cracking and leaks.
