Laticrete Vapor Ban Primer W is a safer, greener all-in-one solution that combines moisture vapor mitigation and priming in a single step. This water-based, ready-to-use formula eliminates the need for mixing components, sand broadcasts, or additional primers, streamlining installation and reducing costs.
With moisture control rated for 100% RH and up to 25 lbs. MVER, it provides reliable protection against flooring failures caused by excessive vapor emissions and alkalinity. The strong bonding performance ensures a stable substrate for final flooring, including self-leveling underlayments (SLUs) of any thickness.
Its epoxy-free, hypoallergenic, low-odor, and low-VOC formula makes it installer-friendly and environmentally responsible. A visual color-change cue confirms proper application, giving added assurance during use.
Ideal for use over new or existing concrete, Vapor Ban Primer W helps contractors work safer, greener, and smarter—without sacrificing performance.
