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
