Duro-Last Strip Mastic User Manual
DURO-LAST® STRIP MASTIC
Description:
Strip Mastic is a high performance, permanent, elastic
butyl tape for use with the Duro-Last® roofing system.
Strip Mastic is excellent in areas subjected to stress
and vibrations as well as expansion and contraction.
Strip Mastic is especially effective in roofing
applications as a sealant against moisture
penetrations around flashings.
Strip Mastic is excellent in areas requiring superior
tensile strength and extensi bility (webbing/elongati on),
in all climates, which is most important with today's
high tech single-ply materials. Strip Mastic is
formulated for adhesions to all types of building
materials. Its superior tack affords tenacious
adhesion to aluminized steel, galvanized metal,
masonry, and wood to ensure a weather tight seal.
