Henry® Pumadeq™ Grip 40 is an elastic coating based on polyurethane modified methyl methacrylate (PUMA) technology. Pumadeq technology combines the speed of PMMA technology in its application with the elasticity of Polyurethane technology. PUMA technology exhibits much greater elongation and flexibility than PMMA technology. Pumadeq Grip 40 is a hard wearing coating which is broadcast with aggregate to form a wearing or direct bonding surface for waterproofing applications and a traffic surface for pedestrian or vehicular traffic applications.
