Application steps

MIXING

Sika® Galvashield® Embedding Mortar should be mixed with a slow speed drill (400/500 rpm) and paddle. Suggested mixing: add up to 3.2 – 3.8 litres of water to each 20kg bag of Sika® Galvashield® Embedding Mortar. Water can be added or deleted to achieve grout consistency desired for placement. Mix for three minutes until fully homogeneous. Mix only as much grout as can be installed in 20-30 minutes.

APPLICATION

Any remaining water should be blown from the drilled hole using oil free compressed air and Sika® Galvashield® Embedding Mortar injected by hand pump to the rear of the hole to avoid air entrapment.
Ensure sufficient grout is placed in the bottom of the hold 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.

CLEANING OF TOOLS

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