UNDERWATER GRADE EPOXY.
A solvent-free underwater grade epoxy compound. Supplied as a component kit.
- 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.
- Serves as a paint (roller or brush)
- Serves for grouting
- Underwater working
- Easy to work, gloss finish
All surfaces must be clean and sound. Also see our Technical data sheet “Preparation of Surfaces”.
Thoroughly mix the contents of the two containers together before use. Should the kit be split, a mixing ratio 1:1 by WEIGHT ONLY must be used. If silica sand extended epidermix 311 is used as a grout, a mixing ratio 3:1 by volume of sand and epoxy resin is advised. In this application, the resin / activator blend should be transferred to a clean, dry container of suitable size, which has been thoroughly cleaned. Run the dry aggregate into the mixed resin and continue mixing until all the aggregate is wetted and a homogeneous mass is produced.

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.
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.
Two-component, solvent free underwater grade epoxy liquid.
The underwater grade epoxy shall be epidermix 311, a two component, solvent free resin system applied in accordance with the manufacturer’s recommendations, a.b.e.® Construction Chemicals.
