Application & Technical Data

Working Data

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

Mix Ratio

For 1 unit of FM 528 (A+B), add 1 pre-measured unit part B to 1 pre-measured unit part A.

Coverage

3/8″ Epoxy Terrazzo: 40 mils dry film thickness yielding 100-130 sq. ft. per unit.

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 100-130 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.

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.

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.
