Add water according to above mentioned ratio into a clean mixing vessel before slowly adding the SikaGrout®-520 powder. SikaGrout®-520 is best mixed in a forced action mixer, for 2 to 3 minutes or until the mix is free of lumps, not longer than 5 minutes. Slow speed drill (maximum 500 rpm) can be also used for mixing. Normal tumble type concrete mixers are not suitable. Do not add extra water or other ingredients. Mix only full bags for best results.

Before pouring, let the mixed grout stand for approximately 5 minutes after mixing to allow entrapped air to escape. Pour into the prepared area in a way that the grout has the shortest distance to travel. Ensure that air displaced by the grout is allowed to escape. When carrying out base plate grouting, ensure a sufficient head of pressure is maintained to keep the mortar flowing. All exposed areas of the mortar surface should be kept as small as possible.

Treatment of exposed surfaces with Sika® Antisol® range curing compound, is highly recommended for large areas of application. Use other approved curing methods such as polyethylene sheeting or wet hessian only for small exposed areas. Do not commence fogging until final set has been reached.

Clean equipment and mixer immediately after application with water. Hardened material can only be removed mechanically.
