100% solid (VOC-free) system desinged to provide a barrier against moisture vapor mitigation of concrete.


Product Description


TERRAZZCO Moisture Mitigation System MMS 950 is a VOC free 2 component epoxy resin system cured with an amine curing agent and applied on the top surface of concrete slabs providing a retarder against moisture vapor transmission for slabs having a relative humidity of 90-99%. The product is mixed and applied onto the top surface of the concrete soaking into and sealing the pored while it builds a thin film layer approximately 6 mils on the surface. MMS 950 yields approximately 300 – 400 square feet per mixed unit. Coverage is based on the porosity of the concrete and may require a second application for very porous surfaces.

  • MMS 950 is required when relative humidity (RH) within the concrete substrate exceeds 75% when tested with in-situ probes.  MMS 950 should be applied to cracks prior to those cracks being filled with rigid epoxy.


  • Floor Aid Flexible Membrane 528 should be used to treat all cracks, control joints & cold pour joints in the substrate. (Do not fill cracks with Flexible Membrane 528.  Rigid epoxy such as  Groutless EZPour Epoxy 158 or Leveling Fill Epoxy 162 should be used)


  • Leveling Fill Epoxy 162 may be required to fill any cracks, voids and/or if leveling is needed.
