- Basic Uses
- Bridge decks
- Parking structures
- Drive ramps and other surfaces requiring a wear and skid resistant surface
- Limitations
- Iso-Flex Epoxy 200 Overlay System should be installed above 40°F and below 90°F.
- Apply only to fully cured concrete.
- Mixing Instructions
- Parts A and B of the Epoxy 200 resin should be mixed separately before combining.
- The mix ratio is 1:1 by volume.
- When combined mix thoroughly with a low speed motor and "Jiffy" paddle.
- Always scrape the container sides and paddle blades.
- Do not aerate the mix.
- Preparation
- Shotblasting must be employed to provide a sound, clean substrate.
- In areas where shotblasting is not feasible, consult the manufacturer for other methods of surface preparation.
- The substrate must be dry at time of application.
Spall Repair:
- An Epoxy 200 grout mix can be used to fill spalls before overlay installation.
- A prime coat of Iso-flex Epoxy 200 should be applied.
- While still tacky place an aggregate filled Iso-Flex Epoxy 200 mortar and screed or trowel to the desired thickness.
- Do not over trowel and ensure proper termination and edge details.
- Installation
- Apply the Iso-Flex Epoxy 200 resin over the prepared surface using notched squeegees and rollers.
- Apply the first Binder Coat as outlined below
- Immediatley load to excess with dry silica sand utilizing 12/20 mesh clean, dry aggregate to full saturation.
- After the binder has cured broom or blow off excess aggregate and apply the second Binder Coat as outlined below.
- Immediatley load to excess with dry silica sand utilizing 12/20 mesh clean, dry aggregate to full saturation.
- After the second binder coat has cured, broom or blow off excess aggregate and apply a lockcoat of Iso-Flex Epoxy 200 resin as outlined below.
