Carlisle Hardcast 305608 All Weather Primer 1 Gallon

Product Description

The CARLISLE HARDCAST 305608 is an all-weather primer formulated for use with CCW roofing and waterproofing membrane systems. Primers of this type are applied to substrates before membrane installation to promote adhesion and ensure a consistent, long-lasting bond. The 305608 ships in a 1-gallon container, making it practical for spot applications, repairs, and small-to-medium project areas. Licensed roofing contractors and waterproofing specialists are the primary installers. This primer is engineered to perform across a range of ambient temperatures and surface conditions, which reduces job-site delays caused by weather windows.

The 305608 is suited for commercial and residential roofing applications where a Carlisle CCW-series sheet membrane or fluid-applied waterproofing product is being installed. Typical scenarios include below-grade waterproofing, plaza deck systems, and low-slope roofing assemblies. The 1-gallon format supports targeted priming of seams, terminations, penetrations, and transition areas where adhesion is critical.

Key Features

• All-weather formula allows application across a broad range of field conditions
• Designed to promote strong adhesion between the substrate and CCW membrane systems
• 1-gallon container provides a manageable volume for detail work and small coverage areas
• Supports use at seams, terminations, and penetrations where bond integrity is highest priority

Compatibility

Designed as a compatible primer for use with Carlisle CCW all-weather waterproofing and membrane product lines. Confirm compatibility with the specific membrane product in the Carlisle CCW product documentation before application.

Installation Notes

Application should be performed by a qualified roofing or waterproofing contractor familiar with Carlisle CCW system requirements. Ensure the substrate is clean, dry, and free of contaminants before priming. Allow primer to reach the tack stage specified in the product data sheet before installing the membrane. Follow local building codes and manufacturer application guidelines for coverage rate and drying time.
