Epoxy Moisture Barrier Primer by LATICRETE

LATICRETE's VAPOR BAN Primer ER is a single-coat, 100% solids, liquid-applied 2-part epoxy coating designed to control moisture vapor emission from new or existing concrete slabs. Requiring minimal surface preparation, it combines the application of a moisture barrier and primer into one step. It also serves as an epoxy primer for concrete before installing self-leveling underlayment products. Ideal for fast-track projects, slab-on-grade construction, and elevated slabs, it protects moisture/pH-sensitive floor coverings and can be used with various flooring types and adhesives. Install in one step, with no sand broadcast or additional primers needed, lowering material and labor costs.
