PRODUCT DESCRIPTION
Pecora ProPerm VP is an
integral part of the ProPerm
vapor-permeable air barrier
system. Pecora ProPerm VP is a
water-based, single component,
primerless, elastomeric, cost
effective, fluid-applied air barrier
membrane for exterior wall
assemblies where it functions
as an air and moisture vapor
retarder. Applied in a single coat
this elastomeric weatherproofing
membrane provides superior
protection from moisture vapor
and air intrusion contributing
to a seamless, durable airtight
building envelope.
BASIC USES
Applied to exterior wall
assemblies where it functions
as a vapor-permeable air and
water-resistive barrier. Pecora
ProPerm VP effectively blocks
air and liquid water movement
and limits the passage of
moisture vapor through the
building envelope. Pecora
ProPerm VP is designed for use
on concrete including block and
precast, exterior grade gypsum
sheathing, plywood, OSB and
many other common building
substrates
