Consumption

Approx. 2 kg of powder for one litre of mortar.
For 1 m3 of mortar approx. 75 x 25 kg bags and 280 litres of water.

MIXING

Powder should be added to the pre-gauged water to suit the desired consistency. For J rote of 12 seconds, approx. 3.75 litres of water. (approx. 15% by weight of SikaGrout®-212-11) should be used. The amount of water may be reduced within the flowable consistency if desired. Mix mechanically with a low speed drill (max. 500 RPM) with a disc agitator attached, until a smooth, even consistency is achieved.

APPLICATION

Pour mortar after mixing. Ensure, that air entrapped into the grout is allowed to escape. When carrying out base plate grouting, ensure sufficient head of pressure is maintained to keep mortar flow uninterrupted. Make sure, that necessary formwork is firmly in place and watertight.
 

 


Grouting of Machine Beds

Prewet thoroughly, no standing water in bolt holes. If possible, grout anchor bolts first, then the mortar bed in a second operation. Ensure continuous flow of mortar. Distance between anchor bolt and substrate to be at least 3 x max. diameter of mortar aggregates (approx. 5 mm.)
 

Grouting of Base Plates

Prewetting for approx. 24 hrs, no standing water. Maintain constant hydro-static pressure to ensure continuous flow. Use cable or chain to make sure that all cavities are filled. Make sure that entrapped air can escape.

CLEANING OF EQUIPMENT

Clean all tools and equipment with water immediately after use. Hardened mortar can only be removed mechanically.
