Elastomeric Multi Use Polyurea


REDGARD ELASTAFLEX 1.0 UB is a very economical self-leveling polyurea is a unique blend of aliphatic and aromatic polymer chemistry with greater color/gloss retention and is more UV resistant than aromatic polyureas. REDGARD ELASTAFLEX 1.0 is formulated to be processed through a special Synergy proportioner such as the Low Pressure Gear Proportioner (LPG).

  • 100% solids, no solvents, and no VOC’s
  • Extended tack time to allow deep surface penetration.
  • Fast-set 1:1 ratio, return to service in hours, not days.
  • Compliant with FDA/USDA for incidental food contact.


  • Roof coating used over metal, polyurethane foam, concrete, and certain single ply membranes.
  • Liner for concrete tanks, ponds, lagoons, reservoirs, dikes, tunnels, barges, etc.
  • Coating for steel or other surfaces subject to corrosion.
  • Encapsulation for EPS or other types of flotation materials.
  • Replace or repair failed sheet membrane liners, steel tanks, silos, and pipes.
  • In between slab waterproofing.
  • Encapsulation for asbestos, lead paint, or other dry hazardous materials.
  • Earthen containment used with geotextile membranes.


– To fill or repair control joints, random cracks, and shallow spalls on concrete surfaces.

Test samples were poured through LPG proportionerwith Static Mix gun at 150 psi at 70˚F (21˚C)
*All cured film properties are approximate since processing parameters, ad-mixture type, and quantities will change physical properties of the cured elastomer. All samples for above test were un-tinted and force cured or aged for more than three weeks. It is recommended that the user perform their own independent testing.
