#309 FLEXGARD T
MOISTURE INSENSITIVE AND LOW MODULUS EPOXY, BLENDED WITH AGGREGATE
309 FlexGard T was designed to provide high strength in thin overlays. Typical overlay thickness ranges between 1/8” and 3/8”.
309 FlexGard T is an extremely versatile product and may be applied over Thermal-Chem’s 309 FlexGard M where a flexible membrane is required or over Thermal-Chem EPIC system where concrete strengthening and crack control is required.
309 FlexGard T is a two-component 100% solids, low-modulus (30% to 40% elongation) moisture insensitive epoxy polymer. 309 FlexGard T may be applied as a seeded broadcast system, blended with selected aggregates for a trowel applied epoxy mortar overlay or as a slurry with an optional broadcast.
309 FlexGard T is formulated for interior or exterior use and possesses excellent impact resistance and wearability, even when exposed to steel wheels carts of high speed bridge traffic. Formulated to meet VOC regulations, 309 FlexGard T may be applied above 40°F (5°C).

USES / APPLICATIONS
Typical overlay uses for 309 FlexGard T include bridge decks, ramps, loading docks, industrial floors, commercial kitchens, worn and polished concrete on elevated or slab-on- grade surfaces, when these conditions are present:
- Concrete with a chloride content at the top mat of rebar of less than 1.2 kg/m3 (2 lb/yd3)
- Rebar with less than 5 cm (2 in) of concrete cover
- High permeability concretes
DATA SHEET
LIMITATIONS
- Will discolor if used as a topcoat and exposed to sunlight
- Do not install 309 FlexGard T on wet surfaces (i.e., in the presence of standing water)
- Minimum cure temperature: 40° F (5° C) Do not thin EPC with solvents
APPLICATION INFO
309 FlexGard T EPC overlays are easily installed by professional contractors and DOT maintenance crews. Refer to Thermal- Chem’s System Installation Guide – Broadcast Industrial Kitchen Flooring System or System Installation Guide – Broadcast Parking Garage.
AGGREGATE SELECTION
Particle shapes, as well as gradation, are important factors in developing a balanced mix that will properly wear and chemically protect the concrete. Larger aggregates may be added to the epoxy mixture for composite mix designs and surface profiling. Subangular silica or aggregates are recommended for EPC’s. Low void content in the sand mixture will require less epoxy resin. All aggregates must be clean and dry. Consult with a Thermal-Chem representative or Thermal-Chem Corporation for factory approved EPC formulations.
