Description
A professional grade material made from special
adhesive asphalts, non-asbestos fibers, special
resins and other ingredients that assure its rapid
and tight fusion to the base surface. Intended
primarily as a blind nailing cement for use with
roll roofing. It creates a tight bond and prevents
buckling and curling of edges. Also suitable
for application to older roofs to seal cracks and
pinholes.
