AIR SHIELD™ TMP is a water-based air/liquid moisture barrier that cures to form a tough, seamless, elastomeric membrane. When properly applied as a drainage plane, AIR-SHIELD TMP allows vapor to pass through; provides excellent resistance to air leakage; while prohibiting liquid water intrusion into the substrate. AIR-SHIELD TMP is suitable for both new construction and retrofit applications and may be applied to most common surfaces and integrated into various wall systems.
