Two-component, epoxy adhesive/repair compound
Two component, solvent free, filled, polyamide cured epoxy. Highstrength, water resistant, solvent resistant and chemical resistant nonslump
bond to cementitious and mild steel surfaces.
Uses:
Repairing and patching defects in concrete, like honeycomb and spalls, fabricating components and fibre cement products.
In applications as a bedding mortar, gap filling and concrete repairs like spalling, crack filling and arrisses repairs.
The viscosity of epidermix® 318 is sufficient to hold its place on horizontal and vertical faces, like soffit repairs.
epidermix® 318 has good damp tolerance, provided the required mechanical preparation to create a mechanical bond has been
implemented.
Surface Preparation
Any surface to be repaired with epidermix® 318 must be clean, mechanically sound, dry or damp. 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.
Mixing
Set up equal volumes of Base and Activator side by side on a clean board. Do not take more than about 250 ml of each compound. Mix thoroughly with a trowel or spatula.
Application
Mixed epidermix® 318 should be pressed into place in the repair area using a small amount first to wet out the surface and then building up the required thickness. The viscosity of epidermix® 318 is sufficient to hold its place in soffit repairs and on vertical faces. If the volume is too big to repair in one placing, leave the contact surface rough to act as a key for a subsequent placing once the first one has set.
A final smooth finish may be obtained by trowelling off the surface of the still uncured epidermix® 318 with a water dampened steel trowel.

Health & Safety
Uncured epidermix® 318 must be regarded as toxic. Gloves should be worn at all times and care must be taken not to ingest any of the material by eating or smoking while working with the compound. If working in a confined space, provide adequate ventilation.
Clean tools with abe® super brush cleaner and use a little of this liquid to remove any splashes on the skin. Wash finally with soap and warm water.
Cured epidermix® 318 is inert and non-toxic.
Packaging
epidermix® 318 is supplied in 200ml, 500ml, 1 litre and 4 litre kits.
Model Specification
General purpose thixotropic epoxy adhesive and repair compound. The adhesive/grout will be epidermix® 318, a two-component, solvent-free, thixotropic, polyamide cured epoxy system applied in accordance with the recommendations of a.b.e.®. The compound will have a 7 day compressive strength of 78 MPa and a lap shear strength on grit blasted steel of 8 MPa.
Protection On Completion
After fully cured, epidermix® 318 can be drilled, sanded, filed and can be coated with an epoxy or polyurethane coating for aesthetic appeal.
Handling & Storage
Epoxy compounds in their uncured state are toxic and prolonged skin contact can give rise to dermatitis. When handling epoxy compounds, use should always be make of disposable gloves and barrier creams. Involuntary habits such as face starching and spectacle adjustment must be avoided. Similarly eating and smoking whilst or after working with epoxy must be avoided until the individual has washed up. This product has a shelf life of 24 months if kept in a cool dry place.
