BETHANY, CONN.—LATICRETE, a manufacturer of globally proven construction solutions for the building industry, announces the launch of VAPOR BAN Primer W, a high-performance, water-based, all-in-one vapor barrier and primer. This next-generation product sets the standard in moisture mitigation, offering a safer, faster, and more sustainable option, without the required mixing of a two-part epoxy.
Designed for ease of use, VAPOR BAN Primer W is moisture rated for 100 percent RH (ASTM F2170) and MVER up to 25 lbs. It simplifies installation by eliminating the need for a separate primer and vapor barrier application. Suitable for both new and existing concrete substrates, the product enables installers to work more efficiently without compromising performance.
As an epoxy-free solution, VAPOR BAN Primer W supports healthier jobsite conditions. It is hypoallergenic, low-odor, and low-VOC, making it an ideal choice for installers sensitive to resins. The water-based, ready-to-use formula avoids the environmental and handling concerns common with traditional epoxies to offer a cleaner, more responsible alternative.
For a Safer & Healthier Work Environment
“Traditional epoxy-based vapor barriers can present challenges related to allergens, environmental impact, and complex application requirements,” said Nicole Gay, Senior Product Manager at LATICRETE. “VAPOR BAN Primer W reflects our commitment to supporting safer and healthier work environments while providing trusted priming and moisture mitigation solutions for any project.”
As it dries, VAPOR BAN Primer W changes color, giving installers a clear visual cue that the surface is ready for the next step. For added convenience, it comes pre-mixed in resealable packaging and is backed by a 25-year warranty when used within a complete LATICRETE system.
VAPOR BAN Primer W joins the company’s comprehensive moisture mitigation portfolio, which also includes VAPOR BAN Primer ER, VAPOR BAN E, and VAPOR BAN ER.
