- General Uses & Applications
- Extends deck life on bridges and structures
- Seals concrete floors and roadways
- Preserves airport runways/taxiways
- Protects columns & beams in splash zones
- Consolidation of porous & dusting surfaces
- Serves as a primer or pre-treatment for subsequent epoxy or urethane deck coatings
- Installation and Coverage
In order to achieve maximum results, proper installation is imperative. Coverage will vary according to the porosity of the concrete. One gallon mixed epoxy covers approximately 150 ft2 (14 m2) at a 13 mil thickness on smooth finished concrete.
- 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 and material properties
- Concrete should be a minimum of 28 days old prior to sealing
- Do not apply if rain is expected; allow sufficient time for the substrate to dry after rain or other inclement conditions
- Avoid overspray or mist conditions when applied by sprayer
- Compressed air equipment must have an oil/air separator
- Maximum of one flood coat application
- When used as a primer or pretreatment prior to overlay, consult ATC representative
- Placement not to exceed recommended temperature as outgassing may occur - see Mix Instructions
