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.
STORAGE & USE
Rolls should be stored upright off the ground and completely protected from the weather. Substrates must be structurally sound, dry, smooth, and meet or exceed minimum requirements of local codes and GCP. Do not attempt application if ice, snow, moisture, or dew are present or inclement weather is expected.
APPLICATION
PERM-A-BARRIER HRA PROTECTION P must be applied in accordance with GCP installation procedures. The following information is intended for general information purposes only and is not all-inclusive.
PERM-A-BARRIER HRA PROTECTION P is installed in a shingle pattern to promote drainage. Install membrane while the PERM-A-BARRIER HRA is hot and has a tacky consistency. Overlap protection course side laps a minimum of 2” (50.8 mm) and end laps a minimum 4” (101.6 mm). Ensure overlaps are secured and fully adhered. No additional HRA material is needed.
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.
