Description

Perm-A-Barrier VPL is a fluid applied, one component, acrylic membrane that cures to form a resilient, monolithic, fully bonded elastomeric sheet when applied to construction surfaces

VPL membrane provides superior protection against the damaging effects of air and liquid water ingress on building structures. The product creates a solid barrier against air infiltration and exfiltration, which minimizes associated energy loss and condensation problems.

This membrane is vapor permeable for wall assemblies requiring this “breathable” characteristic. As a vapor permeable membrane, it permits the transfusion of water vapor that may otherwise condense in the wall structure; but is impermeable to liquid water, which allows the material to act as a water drainage plain.

Compatible with Perm-A-Barrier flashing systems

Surface Preparation

All surfaces must be sound and free from spalled areas, loose aggregate, loose nails or screws, sharp protrusions or other matter that will hinder the adhesion or regularity of the membrane installation. The surface must also be free from frost, dirt, grease, oil or other contaminants. Clean loose dust and dirt from the surface by brushing or wiping with a clean, dry cloth.

Perm-A-Barrier VPL membrane may be applied to green (minimum 3 day cure time) concrete or over damp to-touch surfaces Remove any visible water prior to application.

Membrane Application

VPL membrane can be installed through a spray application. It may be applied by roller or brush, however spray application is the preferred method. If applying product by roller or brush, multiple material passes may be necessary to ensure that the required wet thickness is achieved.

Application Temperature

In spray applications, Perm-A-Barrier VPL membrane may be applied at temperatures as low as 40°F (4°C). It is not recommended for use when cold and/ or damp conditions exist for prolonged periods. The product is a water-based material. As with all water-based materials, it is subject to freezing at temperatures below 32°F (0°C).

Drying Time

This product is dry to touch and can overcoated within 4 hours. Membrane will completely dry through in 24 hours at normal conditions.

Cleaning 

Tools and equipment are most effectively cleaned using a damp cloth and removing material as soon as possible to prevent curing on tools and equipment. For short shutdown periods, material can remain in the lines and equipment. Material should not be left in the lines for any period of time if temperatures are expected to drop below 40°F (4°C).
