Description:
Duro-Last®, Inc. supplies trowelable mastic for use
with the Duro-Last roofing system. Surebond SB-240
is medium weight solvent release mastic that utilizes
synthetic rubber and resins as base products which
provide excellent water-resistant properties and
adhesion.
SB-240 is moisture-resistant, which is most important
with today's high tech single-ply materials. SB-240 is
normally used as an underseal. This product cannot
be used as a splicing cement, pitch pocket filler, night
seal or perimeter flashing adhesive. It is not contact
cement, but a sealant.
SB-240 is formulated for adhesion to all types of
building materials including masonry, wood, metal,
insulation, and galvanized flashing. Its high tack
ensures a weather-tight seal around penetrations.
SB-240 is odorless and easy to use. Cleanup is
easily accomplished with Mineral Spirits or Naphtha.
