Rubberised systems are typically specified by residue content, viscosity window for spraying, storage stability, and rubber modification performance such as elasticity, crack bridging, and improved low temperature flexibility. For waterproofing, key specs include adhesion to concrete, water resistance after cure, elongation or flexibility, and aging resistance. For road work, cohesion development, chip retention behavior, and bond strength may be required. Because rubber increases viscosity and sensitivity to shear, suppliers should also specify pumpability limits, filtration requirements, and recommended application thickness.
