Two-component, solvent-free, filled, amine-cured epoxy tar mastic.


  • Bonding and filling of most construction materials, including concrete to asphalt, especially kerbstones, and cuts in roadways
  • Tack-bonding of rubber. Bridge bearing pads to concrete stoolings
  • Bonding metal framed cats eyes to road ways (tarmac and concrete)
  • Good gap filling properties
  • Not for structural ℓoading, or use in drinkable water
  • High strength, multi use
  • Resistant to motor fuels, oils and water
Surface Preparation

Any surfaces to be treated with epidermix® 315 must be LEAN, MECHANICALLY SOUND and DRY. The surface must be free of all
preparation debris prior to placing the compound.

Bonding / Priming

Model Specification

Two-component epoxy tar paste for bonding and filling of many construction materials.

The bonding material shall be epidermix® 315, a two component, solvent free, amine cured, epoxy coal tar system, applied in accordance with the manufacturers recommendations, a.b.e.®. The compound shall have a 7-day compressive strength of 20 MPa.


epidermix® 315 is supplied in 500 ml and 5l yield metal containers.

Handling & Storage

This product has a shelf life of 24 months if kept in a dry cool place in the original packaging. In more extreme conditions this period might be shortened.

Health & Safety

Wet epidermix® 315 is toxic but non-flammable. Always ventilate the working area well during application and drying. Always wear gloves and eye protection when working with the material and avoid excessive inhalation and skin contact. If material is splashed in the eye, wash with copious quantities of clean water and seek medical attention.

Harmless, but not for contact with food or drinkable water.

When transporting ℓiquids and semi ℓiquids by aircraft, ask for material safety data sheet.
