Repairing and patching defects in concrete such as honeycomb and spalls. Fabricating components and repairing defects in ﬁbre cement products.
• Maximum service temperature: 60 ºC (immersion). • Compressive strength @ 25 ºC: 60 MPa in 24 hours, 75 MPa in 7 days. • Tensile strength @ 25 ºC: 17 MPa. • Lap shear on grit plasted steel: 8 MPa using 2 mm boline thickness. • Non-toxic after cured. • Excellent water resistance. • Resists aliphatic solvents, oils, petrol, diesel fuel. • Resists dilute inorganic acids and dilute alkalis.
Any surface to be repaired with epidermix 318 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.
No priming is required.
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. Mixing ratio – 1 base : 1 activator.
1 m2/L/1 mm thickness (max. recommended thickness 25 mm).
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 water dampened steel trowel. Application by gloved hand or steel trowel.
Tools, brushes and mixing equipment should be cleaned immediately after use and before material has set with abe® super brush cleaner followed by washing with soap and water.

Handling & storage
Epoxy compounds in their uncured state are toxic and prolonged skin contact can give rise to dermatitis. 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.
When handling epoxy compounds, you should always use disposable gloves and barrier creams.
Health & safety
Product safety information required for safe use is not included. Before handling, read product and safety data sheets and container labels for safe use, physical and health hazard information. The safety data sheet is available from your local a.b.e.® Construction Chemicals branch.
