SikaRep®

Multi-Purpose Patching and Repair Mortar

SikaRep® is a one component, cement based, multi-purpose patching and repair mortar, incorporating the use of micro-fibres.

  •  One component: just add water.
  •  Easy to mix, apply and finish.
  •  Good adhesion to sound clean substrates (for enhanced adhesion properties use with Sika Latex).
  •  Shrinkage compensated.
  •  Compatible with the properties of typical concretes.
  •  Vapour permeable.
  •  Non-accelerated set to improve handling in hot temperatures.

Application

Application Information

Layer thickness

 Minimum layer thickness = 5 mm

 Maximum layer thickness = 30mm

 For thickness less than 5 mm, Sika Rep Fine® is available, where min thickness 0.5 mm and max thickness 5 mm per layer.

Ambient air temperature

+8 °C min.

Mixing ratio

4.25 - 4.5 litres of water per 25 kg bag.

Substrate temperature

+8 °C min.

Pot Life

~35 minutes at + 20 °C

Curing time

For best results moist cure immediately after mortar reaches initial set (typically 1-2 hours depending on ambient temperatures), continue moist curing for minimum 48 hours.
Application steps

MIXING

For normal applications add 4.25 - 4.5 litres of water per 25 Kg bag of Sika Rep® depending on the desired consistency. Mixing can be achieved either manually or mechanically. Mechanical mixing is recommended by Sika for quantities greater than 1 bag. Mixing should continue for a max 5 minutes after all the contents of the bag are placed in the mix water.

APPLICATION

Pre-soak the repair surface with clean water and then allow surface to dry (Surface Saturated Dry-SSD). Prime Surface with a slurry of Sika Rep® using a stiff brush. The recommended slurry consists of 5.0 - 5.5 litres of water per 25 Kg of Sika Rep® . While the slurry coat is still damp, apply Sika Rep® to a maximum thickness of 30 mm and compact thoroughly by trowel. For enhanced bonding characteristics use Sika Latex® in the slurry mix or use Sika Top Armatec® -110 Epocem as the bonding medium.

CURING TREATMENT

Use approved curing methods.

For best results moist cure immediately after mortar reaches initial set (typically 1-2 hours depending on ambient temperatures), continue moist curing for minimum 48 hours. Use of a proprietary curing compound, like Antisol® -E, can be used.

CLEANING OF EQUIPMENT

Clean all tools and equipment with clean water immediately after use. Hardened material can only be removed mechanically.
