Key Resin Co. History• Founded in 1993, by Robert Cain, President.• Bob Cain has been the co-chairman of the National Terrazzo and Mosaic Association’s (NTMA) Technical Committee since the mid 1970’s.• Key Resin offers:
– Epoxy Terrazzo Flooring– Resinous Flooring Systems– Moisture Vapor Control Primer, Crack Isolation Membrane– Full Range of Coatings for Concrete Floors and Walls
The purpose of this presentation is to provide general information which will be helpful in specifying terrazzo. The participants will gain an understanding of the various terrazzo systems and how it can be utilized in a variety of design applications.
Course Description
Learning ObjectivesUpon completion, you will be able to:
Explain WHAT Terrazzo is
You will know the HISTORY of Terrazzo
See WHY to specify Terrazzo
How terrazzo can contribute to project sustainability
Explain the different TYPES of Terrazzo
See that the DESIGN POSSIBILITIES are endless
What is Terrazzo
A “poured in place” mortar of portland cement or epoxy resin mixed with chips of marble, glass or other aggregate.
Terrazzo flooring is poured, troweled, cured, ground and polished to a smooth surface to show the chips.

Design & Detail SpecificationsTerrazzo Strips
• Common materials:– White alloy of zinc, aluminum, brass and plastic are recommended– Stainless steel are not recommended as it causes problems when
grinding.
• Review the Expansion Joints and Control Joints in your floor. Do this with your flooring contractor!
• Honor all Expansion and Control Joints – Best Option!– Incorporate joints into the flooring design, if possible.– Specify areas in floor that may require buried control joints.
» Excessive concrete movement may cause cracks or heaving even with membrane treatment.
– Long corridor runs should allow for divider strips perpendicular to the corridor.

SURFACEPREPARATION
The Most Important Factorin the Success of any
Terrazzo Flooring System Application.
Surface Prep – New Concrete
Minimum 28 day cure on standard concrete
Perform moisture testing to confirm suitable levels
Remove all contaminants by chemical cleaning
Concrete Surface Preparation - Follow ICRI Guideline No. 03732
Mechanical bond is important - remove laitance & obtain a uniform surface texture (ICRI CSP #4-5)

Moisture Vapor Transmission
What is MVT?
Moisture Vapor Transmission (MVT) is the natural migration of moisture vapor
through sub-grade earth and building components.
Moisture Vapor Transmission
Epoxy Terrazzo

Moisture Vapor TransmissionPossible Sources of Moisture
• Slabs-on-Grade with No Effective Vapor Barrier
• Elevated Slabs using Pan-Type Construction
• Lightweight Concrete
Occurs when a source of moisture and a non-breathing system on the surface are
present.
