- Typical Uses
MMS 950 is used to mitigate moisture vapor transmission through concrete slabs having 70-95% relative humidity when tested according to ASTM F2170. See the application section below for more information.
- Application
Do not apply to wet surfaces (no visible water). Surface Preparation: All work should be performed by trained or experienced contractors or maintenance personnel. Concrete surface and air temperature must be a minimum of 55°F during installation and cure. Concrete surface temperature must be 5° above the dew point to ensure proper curing. Concrete slab must be tested for relative humidity according to ASTM F2170 (Relative Humidity in Concrete Floor Slab using in Situ Probes). Measurements must be made using Wagner Electronics Rapid RH® 4.0 Smart Sensor and Rapid RH® Easy Reader. Consult installer for job specific slab conditions prior to installing TERRAZZCO® epoxy flooring system. Concrete surface must be free of dirt, waxes, curing agents, and any other foreign materials. Concrete surface should be prepared by shot blasting and any repairs to the concrete must be made prior to applying this product. Through the application process, the temperature of the concrete should be 55o F to 90o F.
Materials Needed
- Hand mixing drill with jiffy blade
- Plastic measuring cups capable of measuring at least 1.25 L (0.7 gal.) purchased at local hardware stores.
- Potable water
- Roller, squeegee or brush.
Mixing & Application
- Pour the pre-measured MMS 950 hardener part B into premeasured MMS 950 part A and mix throughly for two to three minutes using a drill equipped with a jiffy blade.
- Add the 1.25 L (0.33 gal) water and mix for two minutes.
- Add the 1.25 L (0.33 gal) water and mix for two minutes.
- Add the 1.25 L (0.33 gal) water and mix for two minutes.
- Add the 1.25 L (0.33 gal) water and mix for two minutes.
- 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 porosity of the substrate. Multiple coats may be necessary for very porous surfaces. Allow to cure for 5-6 hours.
Clean Up
Thoroughly wash mixing and application equipment immediately after use with water.

Technical Details & Test Data
- Considerations
- Substrate temperature must be a minimum of 55o F before, during and 72 hours after installation. The surface temperature of the concrete must be 5o above the dew point to ensure proper curing.
- The concrete surface must be prepared by shot blasting.
- Depending on porosity of concrete, multiple coats of MMS 950 may be required.
- Substrate must be free of dirt, waxes, curing agents, and other foreign materials.
- An active vapor barrier must be present underneath concrete slabs that are below or on grade.
- Not to be applied on wet surfaces.
- Material must be stored in a temperature and humidity controlled environment.
- If relative humidity exceeds 95%, contact Concord Terrazzo Company at 704-921-4928.
