What dual-function performance criteria define Henry asphalt emulsion sealer and dampproofer products?
Dual-function products must both seal against moisture ingress and provide a durable protective film that resists weathering, minor movement, and surface abrasion. Key criteria include strong adhesion to masonry or roofing substrates, sufficient solids to build thickness, controlled viscosity for vertical surfaces, and flexibility to avoid cracking. They also need predictable cure and water resistance once cured, and in some systems compatibility with reinforcement fabric. For buyers, confirm recommended wet mil thickness, number of coats, cure time limits, and whether the product is suitable for below grade damp proofing versus above grade UV exposure.
