Approximately 30 minutes

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

• After assembly and preparation of forms, make sure all mixing, placing and clean up materials are on hand.
• 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. DO NOT OVER WATER!
• 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 mixing, slowly add the entire bag's content of powder to the water.
• Mix thoroughly with a low speed (400 - 600 rpm) drill using a Sika® mixing paddle (reference Sika product code:108139), a jiffy paddle, mortar 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 uniform in consistency for a maximum 3 minutes (typical).

• Immediately after mixing, place grout into forms in a manner to avoid air entrapment.
• When SikaGrout®-500 Aqua is being placed underwater, ensure that the end of the hose or tremie pipe is kept within the grout as it is being placed. The hose or tremie pipe can be raised during placement to reduce the development of back pressure but should not be raised above the level of the grout. Tap forms and/or vibrate during placement as necessary, to achieve flow and compaction. SikaGrout®-500 Aqua must be confined in the horizontal and/or vertical directions, leaving minimally exposed grout surfaces.
• After grout has achieved sufficient cure, forms may be removed. Grind or trim exposed grout shoulders to desired profile.
• Refer to ACI 305R, the "Guide to Hot Weather Concreting" or ACI 306R, the "Guide to Cold Weather Concreting" when there is a need to place SikaGrout®-500 Aqua while either hot or cold ambient and substrate temperatures prevail. Thinner placements will be more sensitive to actual temperature conditions.
• A mockup should be completed on site and inspected by qualified on site personnel (e.g. the design professional) to ensure that means and methods of placement yield satisfactory results.

• Depending upon actual ambient and substrate temperatures, formwork should be left in place for at minimum 5 days (longer if possible), to prevent moisture evaporation and provide restraint to early age hardened expansion.
• In above ground applications once formwork is removed, per ACI recommendations for Portland-cement concrete, moist curing is required.
• Moist cure exposed surfaces above the waterline with wet burlap and/or polyethylene, a fine mist of water or apply a suitable water based, compatible* curing compound that meets ASTM C309 (e.g. Sika® Antisol®-250 W).
• Curing compounds may adversely affect the adhesion of follow up installations of mortars or protective coatings.
• Protect newly applied material from direct sunlight, wind, rain and frost.
• To prevent freezing of above ground applications, cover with an insulating material (e.g. curing blanket).

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

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.
