A 20 kg bag will be sufficient for 40 to 80 anodes, depending on anode size and mortar thickness.

Sika® Galvashield® Embedding Mortar should be mixed with a slow speed drill (400/500 rpm) and paddle. Suggested mixing: add 3.2 of water for each 20 kg bag of Sika® Galvashield® Embedding Mortar. Additional water (up to a maximum of to 4.0 litres) can be added to achieve the required consistency for placement. Mix for three minutes until fully homogeneous. Mix only as much product as can be installed in 20 to 30 minutes.

Sika® Galvashield® Embedding Mortar may exhibit satisfactory handling characteristics, even though inadequately mixed. This will result in a significantly lower level of performance, or possible failure. It is therefore essential the mixing instructions are strictly adhered to, with particular emphasis on the quantity of water used and the time of the mixing operation.

For Type 2 anode installations (e.g. Sika® Galvashield® CC, Sika® Galvashield® Fusion® T2)

Standing water should be blown from drilled holes using compressed air. Sika® Galvashield® Embedding Mortar is injected by hand pump to the rear of the hole to avoid air entrapment. Ensure sufficient grout is placed in the bottom of the hole to completely embed the entire active length of the Sika® Galvashield® discrete anode. The thixotropic nature of the Sika® Galvashield® Embedding Mortar will prevent significant flow from vertical and overhead holes. Place Sika® Galvashield® Embedding Mortar within 30 minutes of mixing to gain benefit of the expansion system and allow to cure for a minimum of 24 hours, without physical disturbance.

For Sika Galvashield® SM-DAS and Sika Galvashield® SM-DAS-X

Use Sika® Galvashield® Embedding Mortar to fill the area between the anode and the surface of the concrete. Mix the mortar as directed. If the concrete surface contains large voids or depressions, fill them with mortar to ensure no air gaps are left behind the anode. Use a V-notched trowel to spread the mortar completely along the entire length of the anode, leaving a ridged profile of the mortar to ensure proper bonding of the anode to the concrete. Place Sika® Galvashield® Embedding Mortar within 30 minutes of mixing to gain benefit of the expansion system and allow to cure for a minimum of 24 hours, without physical disturbance.

NOTE: Sika® Galvashield® Embedding Mortar is a cement-based mortar and therefore it must be cured immediately after finishing in accordance with good concrete practice.

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