VAPOR BAN MC ER Primer by LATICRETE

Single-step barrier and primer combo! Laticrete's VAPOR BAN MC ER is a 100% solids, two-part liquid epoxy coating designed to control moisture vapor emission in new or existing concrete slabs. Minimal or no surface prep required, it combines barrier and primer applications into one, saving time and effort. Also serves as an epoxy primer for concrete before applying self-leveling underlayments.
