TERRAZZCO® Acoustic Membrane 970 is a 100% solids (VOC free), two-component epoxy system applied to concrete in order to assist with decreasing sound transfer through the finished floor system. When used in combination with TERRAZZCO® resin floor system, Acoustic Membrane 970 provides a crack resistant, resilient and durable floor
TERRAZZCO® Acoustic Membrane 970 can be used in industrial, commercial, retail, institutional facilities and healthcare facilities.
When combined with TERRAZZCO EZPour Epoxy 158, it yields a flexible yet durable epoxy terrazzo flooring finish that is less susceptible to cracking than traditional flooring systems.
Working (Pot) Life: 40-50 minutes @ 75°F
Re-Coat Time: 6-8 hours @ 75°F
Full Set Time: 12-16 hours @ 75°F
Full Cure and Maximum Performance: 5-10 days
For one unit of Acoustic Membrane 970 (A+B,) add one unit of Acoustic Membrane 970 hardener (part B) to one unit of Acoustic Membrane 970 resin (part A).
3/8″ Epoxy Terrazzo: 125 mils dry film thickness yielding 30-40 sq. ft. per unit.
1. Premix Acoustic Membrane 970 resin part A using a low speed drill and jiffy blade for two to three minutes.
2. For one unit Acoustic Membrane 970 (A+B,) add one unit of Acoustic Membrane 970 hardener (part B) to one unit of Acoustic Membrane 970 resin (part A). Mix using the drill
and jiffy blade for two to three minutes. Materials are supplied packaged so that the entire contents of hardener part B is added to the container of resin part A and mixed in the container
3. Pour the mixed material onto the working area and spread using a squeegee or trowel to achieve 125 mils dry film thickness yielding 30-40 sq. ft. per unit. Apply more material to areas showing greater penetration and soaking into the substrate.

TERRAZZCO® Acoustic Membrane 970 resin part A is packaged in a 3.5 gallon container premeasured to contain 1 unit of part A, and TERRAZZCO® Acoustic Membrane 970 hardener part B is packaged in a one gallon container premeasured to contain 1 unit of part B. This allows for easy mixing at the work site by emptying the entire contents of the hardener part B into the resin part A and mixing them in the 3.5-gallon pail container.
Self Life: Epoxy resin system has a 1-year shelf life from the date of manufacture.
Storage Conditions: It is suggested that materials are stored in a temperature and humidity-controlled environment. If this is not possible materials should be allowed to acclimate to controlled environmental conditions of application. Keep resins and hardeners separated from each other until ready for use. Materials should be kept away from sources of ignition. Materials should be stored in their original unopened container.
