- Applications
- General Uses & Applications
- Extends deck life in bridges and parking structures
- Bridge nosing material for joint headers and edges
- Repairs concrete spalls
- Levels or corrects concrete grading or ruts
- Rehabilitates concrete flooring and loading docks
- Installation and Coverage
In order to achieve maximum results, proper installation is imperative. Coverage may vary according to the porosity of the concrete. 1.6 gallons (6.1 L) epoxy plus 113 lb. (51.3 kg) of aggregate yields approximately 1 ft.3 (0.03 m3).
- Clean Up
Always wear appropriate personal protective equipment such as safety glasses and gloves. Clean uncured materials from tools and equipment using a mild solvent, such as CRACKBOND® INDUSTRIAL CITRUS CLEANER from Adhesives Technology Corp. Cured material may only be removed mechanically using a sander or grinder. Collect with absorbent material. Flush area with water. Dispose of in accordance with local, state and federal disposal regulations.
- Limitations and Warnings
- For professional use only
- Do not thin with solvents, as this may affect cure
- Concrete should be a minimum of 28 days old prior to applying as overlay
- Compressed air equipment must have an oil/air separator
- BRIDGE-GARD is a vapor barrier after curing
- For placements > 10 in. and/or structural applications, contact an ATC representative
- Consult ATC when mixing or placing outside of the temperature recommendations listed.
