VAPOR BAN® Primer ER

In a single step, the LATICRETE VAPOR BAN Primer ER is both a moisture vapor barrier and an epoxy primer. This 2-component, 100% solids, liquid-applied epoxy coating is designed to control the emission rate of moisture vapor from new or existing concrete slabs. It requires minimal surface preparation and combines the application of a moisture barrier and a primer in one step. Additionally, it serves as an epoxy primer for concrete before installing self-leveling overlays like VAPOR BAN Primer ER.
