In order to guarantee resistance to frost, freeze thaw cycles and de-icing salts, the Salt Resistance surface of the mortar must be treated with Sikagard®-Wallcoat T.

• Pour 2.6 gal. (10 L) of potable water into a suitably sized and clean mixing container.
• Add a bag of powder while slowly mechanically mixing, using a low speed drill (300 – 450 rpm) with a mud mixer or other suitable
• paddle.
• Mix to a uniform consistency for a minimum of 3 minutes.

• Mixing can also be done in a mortar mixer setup for a direct feed in to wet shotcreting equipment, maintaining the same mixing requirements as when mixing with a drill.
• Once mixed, if a wetter consistency is required, increase the water content up to a maximum of 3.4 gal.(13 L).
• Do not overwater as excessive water will cause severe bleeding, retardation and will reduce the strength and performance of the mortar.
• Extending (“bulking”) the mortar with additional aggregate or adding any other material into the mix is not permitted as this may impact the fire resistance of the mortar.

• At the time of application, the concrete substrate must be SSD (Saturated Surface Dry) with no surface water visible.
• FRP Composite and steel surfaces should be dry and clean.
• Resin surfaces must have an acceptable contact surface to which the mortar will adhere.
• Sikacrete®-213 F is applied by the wet-spray, dense stream or wet-spray, thin stream method (for vertical/overhead surfaces).
• Application equipment should include wet-spray, screw pump systems such as an Aliva® rotor system, Putzmeister®, Bunker® spray concrete system or similar.
• Where there is a risk of vibration or mechanical damage to the surface exists and for overhead applications, the use of a light wire mesh reinforcement is recommended in order to prevent any debonding of the mortar layer.
• Position spray nozzle 18 – 24" (450 – 600 mm) perpendicular to the surface. This will minimize rebound, create a smoother finished surface and will flatten out when applied at the proper pressure.
• The surface of the freshly applied mortar can be finished for up to one hour after application dependent on the temperature and humidity.
• When application requires an aesthetic or protective coating, contact Sika’s Technical Services for guidance.

• As per ACI 308 recommendations for Portland cement concrete, curing is required.
• Moist cure with wet burlap and polyethylene, a fine mist of water or a water based* compatible curing compound.
• Curing compounds adversely affect the adhesion of following lifts of mortar, leveling mortar or protective coatings.
• Moist curing should commence immediately after finishing.
• Protect freshly applied mortar from direct sunlight, wind, rain and frost.

* Pretesting of curing compound is recommended.

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