epidermix 715 – High strength repair compound

• High chemical and oil resistance
• Can be poured, trowelled or modified with aggregate without significantly affecting setting times or strengths
• High strength, stronger than concrete in 2 hours
• Primerless system – excellent bond to a variety of prepared substrates
• Will cure under damp or wet conditions and can be used at low temperatures

Saw cut or cut back the extremities of the repair locations to a depth of at least 5 mm to avoid feather-edging and to provide a square edge. Break out the complete repair area to a minimum depth of 5 mm. Remove all dust and unsound debris contaminants and corrosion deposits. Expose corroded rebar and remove all loose scale and corrosion deposits. Grit blasting is recommended for this purpose and particular care must be taken to ensure that the back of the rebar is cleaned as well. If corrosion has occurred due to chloride attack, the rebar should be high-pressure washed with clean water directly after the grit blasting application. Oil and grease deposits should be removed by steam cleaning, detergent scrubbing or the use of a proprietary degreaser. 

Greater thicknesses should be built up in layers and larger areas should be applied in a chequerboard fashion. Consult a.b.e.^®’s technical department for further information. 

Bond strength: The bond between epidermix 715 and concrete will be stronger than the tensile strength of the concrete itself. 

Shrinkage: epidermix 715 is formulated to reduce shrinkage to a minimum. Linear shrinkage will be approximately 0,8%. No further shrinkage will occur after curing. 

Durability: Cured epidermix 715 performs under temperatures as high as 60°C and down to sub-zero conditions. 

Chemical resistance: Fully cured epidermix 715 is unaffected by water, petrol, oil and most corrosive chemicals. 

Underwater use: epidermix 715 will cure under water. The local a.b.e.^® office should be consulted when considering this type of application. 

Limitations: Do not use in contact with ketones, phenols, strong alkalis and oxidising agents. 

No priming required on concrete surfaces. 

Reinforcing Steel: Apply one coat of dura.^®rep ZR primer at the rate of 7,5 m²/l and allow to dry to an unbroken coating. (see separate data sheet) 

Pour the required quantity of liquid resin into a clean plastic mixing bucket and add the powdered hardener slowly, stirring thoroughly and continuously. Continue mixing for 3 minutes until a uniform consistency is achieved.

1 liter/m²/mm thick

Apply epidermix 715 to the prepared substrate by steel trowel, pressing firmly into place to ensure positive adhesion and full compaction. Where the epidermix 715 is to be used on dense or non-absorbent surfaces the first layer should be mixed slightly resin-rich to ensure good bonding. 

Carefully compact the mortar around any exposed reinforcement. Refer to the ‘design criteria’ for maximum thicknesses in a single application. Thicker sections should be built up in layers. If sagging occurs during application, remove the epidermix 715 and reapply at a reduced thickness. When larger areas are being rendered a chequerboard application technique is suggested. 

For certain applications, epidermix 715 can be poured into place. Consult the a.b.e.^® technical department before proceeding. 

When used for bedding purposes, temporary support might be necessary. The minimum applied thickness of epidermix 715 is 5 mm.

Tools should be cleaned with abe^® super brush cleaner immediately after use before the material has had time to cure.

Three-component, polyester variable mix. Pourable to trowl-able mortar. Fast reinstatement of concrete, bedding, jointing and reprofiling of concrete, masonry and brickwork. Cold, damp cure tolerant. 

The mortar will be epidermix 715, a three-component polyester system applied in accordance with the recommendations of a.b.e.^® Construction Chemicals.

epidermix 715 is supplied in 14,85 kg packs yielding 7,3 liters. 

epidermix 715 F aggregate supplied in 11 kg packs. 

These products have a shelf life of 12 months at 20°C. This will reduce at higher temperatures. The product should be kept in a dry store in its original sealed container.

Wet epidermix could be toxic and flammable. The working area must be well ventilated during application and drying. Naked flames including smoking by the applicators should be avoided.

Always use protective equipment such as clothing, gloves and eye protection when working with the material. Avoid excessive inhalation and skin contact. 

In case of contact with the skin remove with resin removing cream and soap and water. Do not use solvents. When larger areas are being rendered a chequerboard application technique is suggested. If material is splashed into the eye, wash with plenty of clean water and seek immediate medical attention. 

Flash point is 29°C 

Cured epidermix 715 is inert and harmless.
