Easy Pour Gel

Easy Pour Gel is our next generation “one part” urethane gel. The critical chemical balance needed to have a quality product is established during the manufacturing process, not at the job-site. Pour in a pre-measured container of Blue Activator, then thoroughly mix to initiate the cure. The tabs below contain additional information about the properties of Easy Pour Gel.
