24/7 FLASHING CEMENT

DESCRIPTION
ALCO 24/7 Flashing Cement is an asbestos free, revolutionary wet-dry flashing cement, comprised of selected blends of pure cutback asphalt, choice solvents and highly modified polymers. 24/7 is a heavy bodied product with elastomeric qualities that make it an all-purpose, durable cement for wet or dry surfaces, even under water. The revolutionary blending of this product allows it to spread smoothly and easily in cold and hot temperatures. ALCO24/7 has unique chemical compounds which give it great strength allowing it to cure to a tough yet flexible film.

PREPARATION
The surface must be clean, dry and free from oil, grease, dirt, debris and any foreign matter that will interfere with proper adhesion. All repairs must be done before application. On small hairline cracks, fill the crack and feather down all edges.
