PERM-A-BARRIER
®
PRIMER PLUS
Water-based primer for use with Perm-A-Barrier
membranes
Description
Perm-A-Barrier
®
Primer Plus is a water-based primer
which imparts an aggressive, high tack nish on the
treated substrate. It is specically designed to facilitate
tenacious adhesion of Perm-A-Barrier self-adhered
membranes to various substrates including plywood,
oriented strand board (OSB), concrete masonry units
(CMU) and glass faced wall boards.
Advantages
• Excellent adhesion—bonds to substrate and remains
permanently pressure sensitive
• Aggressive tack—provides a tenacious bond to
substrates such as plywood, OSB, CMU and glass
faced wall boards
• Fast drying—increased exibility for application
schedule
• Fast and easy application—by brush or roller
• VOC compliant—water-based, contains
no hazardous or ammable solvents
• Low odor—no noxious fumes
Use
Perm-A-Barrier Primer Plus can be used at 40°F (5°C) or
above.
Availability
Perm-A-Barrier Primer Plus is available in
5 gallon plastic pails.
Installation
Safety, Storage and Handling
Information
Perm-A-Barrier Primer Plus is nonammable in the wet
state. Material Safety Data Sheets (MSDS) are available
at graceconstruction.com, and users should acquaint
themselves with this information. Carefully read detailed
precaution statements on product labels and the MSDS
before use.
The VOC (Volatile Organic Compound) content is <1 g/L,
and it meets the U.S. EPA Volatile Organic Compound
Emission Standard for Architectural Coatings.
Architectural and Industrial Maintenance Regulations limit
the VOC content in
products classied as Architectural Coatings. Refer to
Technical Letters at graceconstruction.com for most current
list of allowable limits.
It is important that Perm-A-Barrier Primer Plus be
protected from freezing. Best storage temperature is
60–80°F (15–27°C). Higher temperatures reduce normal
storage life. Lower temperatures can cause increased
viscosity of a temporary nature. This primer will become
unusable with prolonged storage below 40°F (4°C). Rotate
stock on a “rst in, rst out” basis.
When stored at recommended temperature in the original,
unopened container, this product has a shelf life of 15
months from date of shipment.
Surface Preparation
All surfaces must be free from frost, dirt, grease, oil or other
contaminants. Failure to remove excessive dust may result in
compromised
adhesion of the membrane.
