Mix mortar with approx. 9.6 - 13.4 L (2.5 - 3.5 US gal.) of water per 12 kg (26.4 lb)

Minimum: 15 mm (5/8 in) without reinforcement
Maximum: 40 mm (1 ½ in) without reinforcement

Minimum: 5 °C (41 °F)
Maximum: 35 °C (95 °F)

Minimum: 5 °C (41 °F)
Maximum: 35 °C (95 °F)

Approx. 18 - 22.8 L (0.63 - 0.8 ft³) dependent on water content.

Approx. 12 kg/m² (1.2 lb/ft²) for a 20 mm (4/5 in) layer thickness.

Pour approx. 9.6 L (2.5 US gal.) of potable water into a suitably sized and clean mixing container. Slowly add Sikacrete®-213 F powder while mechanically mixing, using a heavy duty, low speed drill (300-450 rpm) with a mud mixer or other suitable paddle. Mix to a uniform consistency for a minimum of three (3) minutes. Mixing can also be done in a mortar mixer setup for direct feed into wet shotcreting equipment, maintaining the same mixing requirements as when mixing with a drill. Once mixed, if a wetter consistency is desired, increase the water content up to a maximum of 13.4 L (3.5 US gal.). Note: Do not overwater as excessive water/cement ratios may cause severe bleeding and retardation and will reduce the strength and performance of the mortar. Extending (‘bulking out’) the mortar with additional aggregates and incorporating any other material is not permitted as this may impact upon the fire resistance of the mortar.

At the time of application concrete should be SSD (Saturated Surface Dry) with no surface water visible. FRP composite surfaces should be dry and clean. Resin surfaces must have an acceptable contact surface to which the mortar will adhere.

  
Where a risk of vibration or mechanical damage to the surface exists, the use of a light wire mesh reinforcement is recommended in order to prevent any debonding of the mortar layer.

  
Sikacrete®-213 F is applied by the wet-spray, dense stream or wet-spray, thin stream method to vertical and overhead surfaces. Application equipment should include wet-spray screw pump systems, such as an Aliva® rotor system, a Putzmeister®, Bunker® concrete spray system or similar.

  
To achieve the optimum physical characteristics, the spray nozzle must be handled by a trained and experienced operator. Position spray nozzle 450 - 600 mm (18 - 24 in) perpendicular to the surface. This will minimize rebound, create a smoother finished surface and will flatten out when applied at the proper pressure.

  
Allow Sikacrete®-213 F to set sufficiently before finishing or scraping to the desired lines. When application requires an aesthetic or protective coating contact Sika Canada Technical Services for guidance.

The surface of the freshly applied mortar can be finished for up to one hour after application. This finishing time will be dependent upon local conditions, including temperature and humidity.

As per ACI 308 recommendations for cement concrete, curing is required. To achieve performance consistent with the properties recorded on this Product Data Sheet curing must done using recognized curing methods, such as, mist spray or water/damp burlap, white polyethylene film or approved curing compound. Curing must start immediately after finishing. Protect freshly applied mortar from direct sunlight, wind rain and frost.

Remove Sikacrete®-213 F from tools and mixing equipment with water. Cured product can only be removed mechanically.
