- General Uses & Applications
- Preservation overlay for bridge and parking decks
- High friction surface treatments
- Epoxy mortar binder for patching concrete
- Installation and Coverage
In order to achieve maximum results, proper installation is imperative. Coverage will vary according to the porosity of the concrete. First course of 1 gallon neat epoxy, with a minimum of 3/8 in. overlay, will cover 40 ft2 and second course will cover will cover 20 ft2 .
- 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 overlay
- Do not apply if rain is expected
- Consult with ATC when used on exterior slabs on grade subject to freezing or for project specific directions when using as a binder for epoxy mortar
- EPOTHANE T3 is a vapor barrier after curing
- Consult with ATC when mixing or placing outside of the recommended temperature range
