2-component, epoxy repair, filling, sealing and forming mortar

Sika Repair-EP is a thixotropic, two-component, repair, filling, sealing and forming mortar, based on a combination of epoxy resins with refined quartz fillers.

  • Fast cure.
  • Suitable for dry and damp concrete surfaces.
  • Non-shrink curing.
  • Curing is not hindered by high humidity.
  • Excellent adhesion to concrete.
  • High mechanical resistance.
  • Resistant to impact and abrasion.
  • Thixotropic, non-sagging.
  • Vertical and overhead applications possible.
  • Different coloured components (for mixing control).
Usage
As a repair mortar for a variety of applications:        
  • Repair mortar for concrete, cement mortar and stone.
  • Filling holes and damaged corners, edges and joint sides in concrete.
  • Rigid interpretation of broad, non-moving joints.
  • Filling and sealing of cracks (static / no movement).
  • Excellent for manufacturing / forming skirting, coving or sanitary baseboards for floor / wall connections.  
Advantages

Application Information
Mixing Ratio

Component A : Component B = 97.12 : 2.88 (parts by weight).
Layer Thickness

Horizontal: 60mm maximum.

Vertical: 25mm maximum.

Overhead: 10mm maximum.
Product Temperature

Minimum +5°C, Maximum +30°C.
Ambient Air Temperature

Minimum +5°C, Maximum +30°C.
Dew Point

Beware of condensation!

The ambient temperature during application must be at least 3°C higher than the dew point.
Substrate Temperature

Minimum +5°C, Maximum +30°C.
Pot Life

Approximately 90 minutes at +20°C.

The pot life starts when the resin and hardener are added, then mixed. It is shorter at high temperatures and longer at low temperatures. With a larger compact amount of mixed material, processing time will be shortened. In order to lengthen the application time at high temperatures, the amount to be mixed can be part mixed in line with the ratio and by weight. Another method is to cool components A + B before mixing (not below +5ºC).
