Vapor Lock™ 20/23 is a ready to use concrete admixture that has an organic chemical reaction with components of the cement and utilizes free water to eliminate the route of moisture vapor emission. In addition this material will actively repel water. These reactions are a permanent and integral component of the concrete.
Vapor Lock™ 20/23 is designed to be added to any pre-cast cementitious material where finish, color definition, water repellency/proofing and a reduced failure rate is desirable.
