Expert Verdict Reviewed by the SuperArbor Pro Desk

Water-based EPDM adhesives are a common choice for adhering membrane to acceptable substrates with easier cleanup than solvent types. Stir before use, apply at the manufacturer’s spread rate, and allow proper flash-off before rolling the membrane into the adhesive. Confirm the substrate is on JM’s approved list before committing the job to it.

Follow the safety data sheet for handling and ventilation, and keep adhesive away from eyes and skin during application.
