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. ALCO
24/7 has unique chemical compounds which give it great strength allowing
it to cure to a tough yet flexible film.

with superior adhesion to SBS roofing membrane and many common roof
surfaces such as BUR » High resistance to water and
weathering » Adheres to masonry, steel and many other
surfaces » Spreads to smooth, even consistency even in high
temperatures and adheres without sagging » Compatible with
APP torch applied modified bitumen membranes » Manufactured

PREPARATION
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. On larger cracks or
