Moisture Mitigation System MMS 950

100% solid epoxy resin designed to provide a barrier against moisture vapor mitigation of concrete.

TERRAZZCO Moisture Mitigation System 950

TERRAZZCO Moisture Mitigation System MMS 950

Moisture-resistant terrazzo resin for concrete exceeding relative humidity of 75-95%.

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 75-95%. 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.

Re-Coat Time: 5-6 hours @ 75°F

Full Cure Time: 7 days

Mixing Instruction

1. Pour the pre-measured MMS 950 hardener part B into premeasured MMS 950 part A and mix thoroughly for two to three minutes using a drill equipped with a jiffy blade.

2. Add 1.25 L (0.33 gal) water and mix for two minutes.

3. Add another 1.25 L (0.33 gal) water and mix for two minutes.

4. Add another 1.25 L (0.33 gal) water and mix for two minutes.

5. Finish adding another 1.25 L (0.33 gal) water and mix for two minutes.

6. Once the mixture has been thoroughly mixed, the product may be applied by roller, squeegee, or brush. Apply evenly with no puddles, making sure of uniform coverage. Coverage will vary depending upon the porosity of the substrate. Multiple coats may be necessary for very porous surfaces. Allow curing for 5-6 hours.

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)
