Two-Component Structural Repair Epoxy Mortar. 

Two-component, solvent-free, filled, polyamide cured epoxy. Repairing and patching defects in concrete such as honeycomb and spalls.

  • Easily installed by gloved hand.
  • Easily smoothed to finish off.
  • Holds perfectly in overhead work.
  • Non-slump in vertical.
  • Needs no priming.
  • Strengths way above surrounding concrete.
  • Resistant to oils, fuels, water, dilute chemicals.
  • Non toxic in water containment.
Surface Preparation

Any surface to be repaired with epidermix 314 must be clean, mechanically sound and dry. The surface should be chipped to expose main aggregate and in the case of honeycomb, all suspect material must be cut out. The surface must be free of all debris prior to placing the compound.

Bonding / Priming

Self priming.

epidermix 314 is a heavy paste to the extent that it can only be mixed by kneading with gloved hands. Set up equal volumes of base and activator side by side on a clean board. Do not take more than about 250ml of each compound at one time. Knead the two components together (like mixing bread dough) for at least five minutes.

Mixed epidermix 314 should be pressed into place in the repair area, always using a GLOVED HAND. The viscosity ofepidermix 314 is sufficient to hold its place in soffit repairs and on vertical faces. If the void is too big to fill in one placing, leave the contact surface rough to act as a key for subsequent placing once the first application has set.  A final smooth finish may be obtained by trowelling off the surface of the still uncured epidermix 314 with a water-dampened steel trowel.

Protection on Completion

Against traffic and spillage until cured. Most epoxies chalk and degrade in extensive sunlight.

Model Specification

Two component epoxy mortar. The mortar shall be epidermix 314, a two component, solvent free, polyamide cured epoxy mortar applied in accordance with the manufacturers recommendations, a.b.e.® Construction Chemicals. The cured mortar shall have a compressive strength of 74 mPa in seven days and be resistant to aliphatic solvents, oils, petrol and diesel fuel.


epidermix 314 is supplied in 2l and 4l kits.

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

Uncured epidermix 314  is toxic and flammable. Always ventilate the working area well during application and drying. Avoid flames in vicinity. Always wear gloves 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.

Cured epidermix 314 is inert and harmless.  When transporting liquids and semi liquids by aircraft, ask for material safety data sheet.
