TERRAZZCO Flexible Membrane 528

TERRAZZCO Flexible Membrane 528

A crack-resistant and resilient terrazzo flooring system

 

TERRAZZCO® Floor Aid Flexible Membrane FM 528 is a 100% solids (VOC free), two-component epoxy resin system applied to concrete in order to assist with the prevention of substrate cracks transferring through to the finish floor system due to horizontal movement. When used in combination with TERRAZZCO® EZPour Epoxy 158 resin floor system FM 528 provides a crack resistant, resilient, and durable floor.

Typical Uses of Floor Aid Flexible Membrane 528

TERRAZZCO® Floor Aid FM 528 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.

Advantages of Flexible Membrane 528

  • Crack-resistant, flexible yet durable
  • Lowers lifetime maintenance costs
  • Reduces noise created by mechanical vibrations
  • Packaged and premeasured for easy mixing at worksites
  • Manufactured and supplied from the Southeast United States
  • Resin is GREENGUARD and GREENGUARD Gold certified

Packaging

TERRAZZCO® Floor Aid Flexible Membrane 528 resin part A is packaged in a 3.5 gallon container premeasured to contain 1 unit of part A, and TERRAZZCO® Floor Aid Flexible Membrane 528 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.

Product Information

Self Life: Epoxy resin does not have a shelf life and hardener has a 1-year shelf life in unopened containers.

 

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.

 

VOC Contents: Zero VOCs

Mixing Instructions

1. Premix FM 528 resin part A using a low-speed drill and jiffy blade for two to three minutes.

 

2. For one unit Flexible Membrane 528 (A+B) add one unit Flexible Membrane 528 hardener (part B) to one unit Flexible Membrane 528 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 40 mils dry film thickness yielding 300 sq. ft. per unit. Apply more material to areas showing greater penetration and soaking into the substrate.

TERRAZZCO Epoxy Resin
  • 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.
