VersaShield
Rolled Moisture Barrier for Concrete Floors
For floors up to 95% RH
A dimensionally-stable, four-ply composite product, engineered as a rolled moisture barrier system
for all grades of concrete. Protects against moisture up to 95% RH.
Features:
o Suppresses extreme moisture emission levels in concrete up to 95% RH
(Relative humidity) ASTM F2170
o Ideal for vinyl tile (LVT, VCT), carpet tile, engineered wood and laminate
o Saves installation time and money by as much as 85%
o Quick and easy to install with no mixing, special tools, or cleanup required
o Protects against alkalinity and promotes flooring adhesion
o Mold and fungus resistant (ASTM D3273)
o Exceptional lay flat performance
o Excellent for planned flooring removal on jobs designed to be replaced
o 10 Year Limited Warranty
Special Note: One roll of VersaShield requires one roll of 2 inch wide (grey) VersaShield Tape (180 lineal feet) to install. The use of 4 inch
wide rolls of VSM-DS double-sided tape (100 lineal feet) is required for utility purposes at door threshold plates, around walk off mats,
floor boxes, pillars and non-flat flooring surfaces. Calculate the required number of rolls of 4 inch wide VSM-DS double-sided tape, based
on the size of the project and the total number of areas requiring this application.

Rolled Moisture Barrier for Concrete Floors
For floors up to 95% RH
Installation Instructions
VersaShield® is a preformed vapor retardant membrane designed to reduce the upward
•
Press the tape firmly and smoothly onto VersaShield with a hand roller to remove any
bubbles, wrinkles, gaps, or other defects that would permit passage of moisture vapor.
•
VersaShield double-sided 4" tape (white) must be used for utility purposes at door
threshold plates, around walk off mats, floor boxes, pillars and non-flat flooring surfaces.
•
Concrete must be smooth, clean, and free of debris, oily material, coatings, and other
surface treatments.
•
Unroll VersaShield double-sided 4" tape (white) with release liner attached, cut at
desired length, apply to concrete surface.
•
Firmly press on the release liner using a hand roller, peel off the release liner section by
section as the VersaShield using a hand roller or 100 pound roller.
movement of water vapor from concrete floor slabs into finished flooring systems. VersaShield
can be installed on elevated slabs (structural concrete, precast, or slabs on metal decks) and
on slabs on-ground (on-grade and below-grade). VersaShield is not designed, intended, or
warranted to resist liquid water pressure (hydrostatic pressure).
Moisture Testing
•
Testing must be conducted prior to initial VersaShield installation with results
documented and retained in order to be in compliance with the VersaShield Limited
Warranty
•
Testing must be conducted in accordance with the latest version of ASTM F2170; a
maximum reading of 95% RH is allowed
•
Step 3: Installation Of Flooring
Do not install VersaShield on slabs below-grade where hydrostatic pressure exists
•
Install floor covering on top of VersaShield mineral-coated (rough) surface in
accordance with the flooring manufacturer's written instructions.
•
Acclimate the floor covering at the installation site per the flooring manufacture's
requirements.
•
The floor covering manufacturer's recommended installation guidelines must be
followed using recommended adhesives and application guidelines.
•
Apply the floor covering manufacturer's recommended adhesive directly onto the
VersaShield grey mineral-coated surface.
•
Take care not to scratch, rip tear, puncture, or damage the VersaShield while spreading
adhesive.
Residual adhesives must be scraped down to the concrete surface and removed prior
•
VersaShield's surface is non-porous; Adhesives will take longer to flash off.
to installation of VersaShield.
•
If the flooring manufacturer has specific recommendations regarding adhesive and
trowel size for different types of concrete, VersaShield rolled moisture barrier should be
considered non-porous.
•
If installing LVT, VCT, or SVT, ensure the seams of VersaShield are offset from the seams
of the LVT, VCT, or SVT. Vinyl plank type tile should be installed perpendicular (90
degrees) to the VersaShield seam pattern.
•
If installing carpet and carpet tiles, the carpet tiles should be adhered directly to the
VersaShield. Ensure the seams of the VersaShield are offset from the seams of the
carpet. Most wide width carpets may be installed over VersaShield.
•
Some pattern match carpets may require stay nailing, knee kicking, crab stretching, or
power stretching. These applications are not approved, as they may act to damage or
distort the VersaShield.
•
VersaShield is not approved for use with unitary backed carpets.
•
If installing laminates and engineered wood flooring, planks should be installed
perpendicular (90 degrees) to the VersaShield seam pattern.
•
Ensure the seams of the VersaShield are offset from the seams of the laminate and
engineered wood flooring.
•
Floating (non-adhered) floor covering is installed according to the manufacturer's
instructions. VersaShield is not recommended for use with mechanically fastened floor
coverings.
•
There are many variations of each type of floor covering. Always check with the flooring
adhesive manufacturer for approved product use, application instructions, and best
practices.
Preparation Of Concrete Subfloor
•
All joints, cracks, and variations in the concrete surface 1/8" or greater must be filled.
•
Use a quality patching and/or leveling compound warranted by the compound
manufacturer to withstand high moisture conditions.
•
Protrusions must be ground flat.
•
All patching, leveling, and/or crack suppression materials must be cured and surfaced
dry before installing VersaShield.
•
Concrete slab surface must be dry, smooth, clean, flat, and structurally sound within
flooring manufacturer's specifications.
•
•
Do not use solvent-based adhesive remover chemicals; certain oils, solvents, and
contaminates in the concrete may cause damage to VersaShield and should be
removed. If contaminants are known or suspected, contact Halex Corporation at 800576-1636.
Step 1: Installation Of Versashield
•
Acclimate VersaShield rolls for a minimum of 24 hours at the job location.
•
Install the smooth side (light grey) down and the rough mineral-coat surface (dark grey)
surface facing up.
•
Starting in one corner of the room, unroll VersaShield flush with existing wall and cut
required to length.
•
Roll out VersaShield rolls, tightly butting the side edges to one another; be sure to not
overlap seams.
•
Limit individual lengths of VersaShield to 25 linear feet.
•
Tape all seams with VersaShield Seam Tape (2" grey) and roll with a hand roller to insure
a good bond.
•
VersaShield is easily cut to fit around irregular objects such as pillars and poles; use
VersaShield Seam Tape to secure the seams in these areas.
Step 2: Installation Of Versashield Seam Tape
•
Store VersaShield Seam Tape indoors in a cool, dry area at temperatures between 60ºF
and 80ºF.
•
VersaShield Seam Tape is marked with the VersaShield logo on the tape and tape core
for identification; use of any seam tape other than VersaShield is never recommended
Step 4: Cleaning And Maintenance
and will void the VersaShield
•
Upon completion of the finished flooring installation, Halex Corporation requires a
minimum of 5 days (120 hours) prior to conducting initial cleaning or maintenance.
•
Failure to follow this requirement may result in improper drying and interruption of the
normal curing process of the adhesive.
•
After waiting the prescribed time period, accepted cleaning and maintenance
procedures may begin.
Limited Warranty.
•
Butt edges of VersaShield Flooring Underlayment as close together as possible, but DO
NOT OVERLAP SEAMS.
•
Apply VersaShield Seam Tape over all the seams to completely seal the gap between
the adjacent VersaShield sheets.
