TW MOISTURE WRAP

Above Grade Moisture / Air Barrier Membrane

APPLICATION INSTRUCTIONS

PREPARATION

All surfaces must be dry and clean. Dirt, dust and any other

foreign matter must be removed. TW MOISTURE WRAP

must be applied when air, substrate, and membrane tempera-

tures are above 40 degrees F.

Acceptable surfaces are cast-in-place concrete, pre-cast

concrete, concrete masonry blocks, exterior gypsum sheath-

ing, plywood, OSB, DensGlass

, DensGlass Gold

, felt-

faced and foil-faced polyisocyanurate foam insulation, EPS

/ XPS, ICF, wood, vinyl or metal surfaces. Concrete must be

allowed to cure for a minimum of 7 days prior to application

of TW MOISTURE WRAP.

PRIMING

Priming is generally not required for most substrates pro-

vided they are clean and dry. However, on concrete, masonry,

DensGlass

and DensGlass Gold

as well as any additional

surfaces where adhesion is found to be marginal, prime the

surface receiving ashing with the appropriate primer, TWP-1

Quick Dry Primer** or TWP-2 Water-Based Primer at the

designated coverage rate according to primer application

instructions for specied weather conditions. DO NOT USE

TWP-1 Quick Dry Primer on

EPS / XPS or ICF surfaces.

FASTENING

Mechanical fastening using a smooth-shank fastener is recommended in situations where adhesion is found to be marginal after

priming. Stapling individual pieces of ashing around the entire perimeter of the ashing 18" on center will maintain attachment

to the substrate.

GENERAL APPLICATION

Unroll TW MOISTURE WRAP and cut to the desired length. Begin by removing approximately 12 inches of the release lm

and center the membrane over the area to be covered. Firmly press or roll the membrane against the substrate and continue pull-

ing the release lm off while smoothing the membrane into place.

SPECIFIC APPLICATION

The remaining portion of these application instructions addresses specic applications of the TW MOISTURE WRAP mem-

brane for full coverage envelope applications and window and door perimeter applications.

Be sure to read through these instructions to rst identify the application method which is specic to your installation before you

begin the application process.

Failure to properly apply TAMKO TW Moisture Wrap according to the Application Instructions may affect coverage under the

applicable 5-year limited warranty.

FULL COVERAGE ENVELOPE APPLICATIONS

In full coverage envelope application, TW MOISTURE WRAP should be tightly sealed into roong and below-grade water-

proong systems and structural perimeter ashings to retain the integrity of the air barrier throughout the entire structure. Note

that in full coverage envelope applications, the dew point must be engineered to the outside of the building. Side laps must be a

minimum of 2 inches and end laps should be 4 inches. All terminations must be sealed with TWM-1 Mastic.

For DensGlass and DensGlass Gold sheathing and OSB, all air and vapor barrier applications are to be done vertically with

membrane no longer than 6 feet. Material must be broomed in using a stiff, hand-held broom.

CAUTION: The National Institute for Occupational Safety and Health has concluded that the fumes of heated roong

asphalt are a potential occupational carcinogen. The physical nature of this product may help limit any inhalation or dermal

hazard during application and/or removal. However, physical forces such as sawing, grinding or drilling during demolition

work and heating or burning may increase the inhalation or dermal exposure hazard of this product. Take precautions to

prevent breathing and contact with skin.

** WARNINGS AND HAZARDS

TWP-1 contains combustible solvents. Avoid exposure to sparks, open ame, heat, and other forms of ignition. Use in well ven-

tilated areas. Avoid breathing vapors. Refer to MSDS for detailed product information and warnings.
