TERRAZZCO® Groutless™ EZPour Epoxy 158 matrix has been formulated to cure with fewer pin holes reducing the amount of labor required in the grouting phase of any terrazzo project. This factor leads to lower labor costs and lessens the time needed to finish a terrazzo floor installation. In addition to dramatically fewer pin holes during the installation process, the terrazzo is also less likely to develop new pin holes commonly caused by regular floor maintenance during the life span of the floor. When combined with an extensive variety of decorative aggregates and poured in place to 1/4” or 3/8” nominal thickness, it yields a highly decorative terrazzo flooring system. Groutless™ EZPour Epoxy 158 provides incredible sustainability and high resistance to wearing while also being resistant to bacterial growth. The product also has the lowest life cycled cost of any flooring system available. Crack-resistant installation of TERRAZZCO® Groutless™ EZPour Epoxy 158 can be achieved when installed in conjunction with a TERRAZZCO® moisture vapor mitigation MMS 950 and flexible membrane FM 528.

- Typical Uses
- TERRAZZCO® Groutless™ EZpour Epoxy 158 is perfect for almost any surface where a uniformly even, a highly durable product is desired. TERRAZZCO® Groutless™ EZpour Epoxy 158 provides the best in esthetic value and innovation. As a result, this epoxy terrazzo is ideal for commercial, industrial, and institutional uses. Groutless™ EZpour Epoxy 158, when integrated with marble or granite aggregate resists heavy industrial wear and chemical corrosion making it perfect for pharmaceutical and chemical plants. TERRAZZCO® Groutless™ EZpour Epoxy 158 is the superior decision for educational institutions, medical centers, sports facilities, and institutions because of its hygienic, smooth surface that is effortless to clean.
- Groutless™ EZpour 158 resin often contains recycled materials such as fumed silica as well as waste filler powders from the glass and mineral industry. Combine this product with locally sourced and/or recycled materials and you will have the perfect environmentally friendly flooring surface that will most likely be used for the entire life cycle of the building in which they are installed.
- Application
Surface Preparation: All work should be performed by trained and 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°F above the dew point to ensure proper curing of the terrazzo floor.
Consult installer for job specific slab conditions for TERRAZZCO® epoxy terrazzo flooring system installation. Concrete surface must be free of dirt, waxes, curing agents, and any other foreign materials. Surfaces should be prepared by grinding or shot blasting and any repairs to concrete must be made prior to applying this product. An active vapor barrier under the concrete must be made prior to applying this product. An active vapor barrier under the concrete slab is required. Concrete slabs receiving resinous terrazzo flooring must be tested for relative humidity according to ASTM F-2170 (Relative Humidity in Concrete Floor Slabs using in situ probes). Measurements must be made using Wagner Electronics Rapid RH® 4.0 Smart Sensor and Rapid RH® Easy Reader. RH reading below 75% do not require the application of a vapor moisture mitigation system. 75% of higher requires the use of Moisture Mitigation System MMS 950. A record sheets should be filled out that includes the ambient temperature and humidity during testing along with the substrate temperature and relative humidity. The test must be conducted at end user environmental conditions. Any deviation from this procedure will result in the warranty being voided.
Materials Needed
- Mineral spirits or isopropyl alcohol for cleaning equipment.
- Mixing equipment appropriate for work site.
Mixing Application
Premix TERRAZZCO® Groutless™ EZPour Epoxy 158 resin Part A before using. Mix five (5) parts of TERRAZZCO® 158 resin part A with one (1) part of TERRAZZCO® hardener 158 Part B by volume with a slow speed drill until liquids are completely blended. Introduce the appropriate amount of aggregate and continue to mix.
Clean Up
Clean skin with soap and water. Tools and equipment should be cleaned with isopropyl alcohol or mineral spirits before the epoxy hardens. Failure to do so will cause the epoxy system to harden on the tools and equipment making it very difficult to remove. Consult SDS for safety and health precautions.
- Maintenance
Terrazzo flooring made with TERRAZZCO® Groutless™ EZpour Epoxy 158 is simply cleaned with neutral soaps or detergents. Regular mechanical scrubbing is recommended for all surfaces having a non-skid texture. Long periods of heavy foot traffic may necessitate reapplication of a finish coat. We also advise the owner to consult the National Terrazzo & Mosaic Association guidelines for maintaining terrazzo surfaces.

Technical Details & Test Data
- Considerations
- Substrate temperature must be between 55o and 90o 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 of the terrazzo floor.
- Substrate must be free of dirt, waxes, curing agents, and other foreign materials. The concrete surface must be prepared by shot blasting or by grinding.
- All control joints and expansion joints in the substrate must be revealed with the appropriate divider strips in the terrazzo topping.
- An active vapor barrier must be present under concrete slab.
- Materials should be allowed to acclimate to controlled application environmental conditions prior to being mixed.
- Material is not designed to be used as a moisture vapor barrier.
