It bonds tenaciously to concrete surfaces as early as 48 hours after placement and holds back up to 12 pounds of moisture vapor transmission. The formula is unaffected by pH levels up to 14, making it suitable for challenging slab conditions. This product is Part A Resin, supplied in a gallon container with a net fill of 59 fl oz. When combined with Part B Hardener (sold separately) and the required water, the two components yield 1.5 gallons of usable material. Licensed flooring installers and commercial floor coating applicators are the typical end users.\u003c\/p\u003e\u003cp\u003eThis primer is designed for use as a standalone vapor barrier under a wide range of finish systems.
