Safety & Handling

PERM-A-BARRIER® products must be handled properly. Do not handle until all safety precautions and instructions have been read and understood. Refer to product label and SDS before use. SDSs can be obtained from www.gcpat.com or by contacting your local representative.


APPLICATION

PERM-A-BARRIER HRA FABRIC must be applied in accordance with GCP installation procedures. Do not attempt application if ice, snow, moisture, or dew are present or inclement weather is expected. The following information is intended for general information purposes only and is not all-inclusive.

Using a flat squeegee, install PERM-A-BARRIER HRA to the properly prepared and primed substrate at a minimum 90 mils (2.3 mm) thick. While hot and tacky place the PERM-A-BARRIER HRA FABRIC in the hot rubberized asphalt and work air pockets from under the reinforcement by using pressure from a broom or the application squeegee. PERM-A-BARRIER HRA will begin to saturate the fabric from below. Pour additional PERM-A-BARRIER HRA over the reinforcement and squeegee to a minimum 125 mils (3.2 mm) to fully encapsulate the PERM-A-BARRIER HRA FABRIC within the hot rubberized asphalt. Overlap fabric side laps a minimum of 2 inches (50.8 mm) and end laps a minimum of 4” (101.6 mm).  Ensure overlaps are secured tightly with hot rubberized asphalt.

Cold weather applications require special handling to prevent damage to the rolls and ensure satisfactory installation. Do not apply waterproofing systems over improperly prepared substrates or substrates that contain moisture. Rubberized asphalt temperature in the melter must be 380°-400°F (193°-204°C) to ensure proper adhesion.
