Underwater Grade Epoxy
A solvent-free underwater grade epoxy compound. Supplied as a component kit.
Uses
- Lining inside of damp concrete pipes (standard epoxies will not adhere).
- Underwater repair of ships’ hull coatings.
- Lining up-stream of concrete dams to stop seepage.
- Flooring – on wet floors – where dampness is a result of water applied on surface (not rising dampness), e.g. dairies, abattoirs and other environments.
- Underwater grouting or patching. May be used as a grout with graded silica sand. Mixing ratio 3:1 by volume of sand and epoxy resin.
- May be applied as a paint by roller or brush underwater
Advantages
- Serves as a paint (roller or brush)
- Serves for grouting
- Underwater working
- Easy to work, gloss finish

Application
epidermix 311 applies equally well underwater or above water. epidermix 311 bonds directly by displacing the water on a surface. epidermix 311 does not tend to emulsify or crawl when brush or rolled underwater, or on a damp surface. epidermix 311 hardens in 24 hours underwater at ambient of about 25°C. Good leveling, flow, gloss and flexibility is achieved.
Note: epidermix 311 must always be used in such a way as to prevent moisture ingress. It may not be used to seal dampness into a surface.
Cleaning
Clean equipment with abe® super brush cleaner, and then rinse with clean water.
Protection on Completion
Protect against UV if not permanently underwater. Most epoxies chalk and degrade in extensive sunlight.
Model Specification
