Sikacrete®-360 SCC

Portland cement based formulation containing select fillers, aggregates and special additives.

12 months from date of production if stored properly in original, unopened and undamaged, sealed packaging. 

Store in a cool, dry, well-ventilated conditions, out of direct sunlight at 40 - 95 °F (4 - 35 °C). Protect powder from moisture. If permitted to become damp, discard material. 

*Mortar scrubbed into mechanically prepared, saturated surface dry (SSD) substrate. 

* If repair requires multiple lifts, each lift should be applied as soon as the previous lift has developed enough initial strength to support it.

Condition to 65 - 75 °F (18 - 24 °C) before use.

40 °F (4 °C) minimum / 95 °F (35 °C) maximum

6 to 6.5 pints (3.4 to 3.7 liters) of clean, potable water per 65 lb. (29.5 kg) bag

40 °F (4 °C) minimum / 95 °F (35 °C) maximum

Approximately 60 minutes

Temperatures will affect the pot life:

• Above 73 °F (23 °C) will reduce the pot life
• Below 73 °F (23 °C) will increase the pot life

0.50 ft³ (0.01 m³) per bag (Coverage figures do not include allowance for surface profile and porosity or material waste)

• Initially wet down all contact parts of mixing equipment.
• Pour the appropriate volume of clean water, approximately 70 °F (21 °C) into a suitable mixing container or appropriate mortar mixer.
• Start with a minimum of 6 pints (3.4 liters) of water. An additional half pint (0.3 liter) can be added if needed. DO NOT OVER WATER! Excess water may cause segregation.
• Ambient and material temperatures should be as close as possible to 70 °F (21 °C). If higher, use cold water. If colder, use warm water.
• While mechanically mixing, slowly add the entire bag's contents of powder to the water.
• Mix thoroughly with a low speed (400 - 600 rpm) drill using an appropriate mixing paddle, or in an appropriate mortar mixer to avoid entraining too much air and until homogenous with no lumps. Scrape side walls of container to ensure a proper mix. 
• Mix until visibly uniform in consistency for a maximum 3 minutes (typical). Thorough mixing and proper proportioning are necessary. Do not over mix.

• Ensure substrate is properly prepared and saturated surface dry (SSD) before installation.
• Ensure good intimate contact with the substrate is achieved either by use of a bonding agent, a scrub coat application or other suitable means such as pumping under pressure.

Horizontal, Flat Installations

• After filling repair area, screed the material.
• Allow Sikacrete®-360 SCC to set to desired stiffness, then finish with a broom or burlap drag for a rough finish, or a wood or sponge float for a smooth surface. For a smoother finish, a magnesium float can also be used.
• To assist in the finishing process, use SikaFilm® finishing aid. Please consult with the current product data sheet for additional information.

Form and Pour / Form and Pump Installations 

• Tap form lightly while pouring or pumping. DO NOT VIBRATE
• Pump with a variable pressure concrete pump.
• Continue pumping until a 3 to 5 psi (20 - 34 kPa) increase in normal line pressure is evident, then STOP pumping.
• Form should not deflect.
• Vents are to be capped when steady flow is evident.
• Forms are stripped when a sufficient amount of cure time has elapsed, based on actual temperature conditions.

• Refer to ACI 305R, the "Guide for Hot Weather Concreting" or ACI 306R, the "Guide for Cold Weather Concreting" when there is a need to place Sikacrete®-360 SCC while either hot or cold temperatures prevail. Thinner placements will be more sensitive to actual temperature conditions.

• As per ACI recommendations for Portland cement concrete, curing is required.
• Depending upon actual ambient and substrate temperatures, formwork should be left in place as long as possible to reduce the rate of moisture evaporation (typical minimum 3 days or longer).
• Moist curing should commence immediately after finishing exposed surfaces.
• Moist cure with wet burlap and polyethylene, a fine mist of water, or a water based compatible* curing compound compliant with ASTM C309 (e.g. Sikagard®-1315 KNS).

         * Pretesting of non-Sika water based curing compound for compatibility is recommended.

• Curing compounds will adversely affect the adhesion of following layers of mortars, leveling mortar or protective coatings. 
• Protect newly applied material from direct sunlight, wind, rain and frost.
• To prevent from freezing, cover with insulating material (e.g. curing blanket).

Uncured material can be removed from equipment surfaces and finished surfaces with water. Surfaces should be cleaned immediately after use. Cured material can only be removed from surfaces by mechanical means.
