EQUIPMENT
SikaGrout-212 HP must be mechanically mixed using a mechanical grout mixer or a suitable drum mixer. The grout mixer will reduce the chances of the mix becoming lumpy or aerated. Smaller quantities should be mixed in clean drum using an electric drill and
spiral drill and spiral mixer at a speed of approximately 500 rpm.
DO NOT MIX BY HAND.
MIXING
SikaGrout® -212HP can be mixed with a low speed (400~600 rpm) mixer to avoid entraining too much air. Mix only full bags for best results.
Pour the water in the correct proportion into a suitable mixing container. While stirring slowly, add the powder to the water and mix thoroughly at least for 3 minutes till a homogeneous mix is achieved. Wait for 1 to 2 minutes to allow the entrapped air to escape then mix again for 1 to 2 minutes.
APPLICATION
Pour grout immediately after mixing into the prepared openings. Ensure air displaced by the mortar can easily escape; otherwise entrapped air will prevent full contact grouting.
When grouting base plates etc., ensure that a continuous and sufficient head of pressure is maintained to keep grout flowing. To make optimum use of the products expansion properties apply the grout as quickly as possible (refer to Potlife).
In case of large volume / high layer thickness grouting clean, graded gravel may be added to the grout mix (up to 100% be weight of grout). Round pebbles in general are better the crushed stone. Grading should be in the ranges of 4 to 8 mm, 8 to 16 mm and 16 to 32 mm. Pre-trials are required to defined grading and mixing ratio for best results.
CURING TREATMENT
Keep visible exposed grout surfaces to a minimum. Protect the fresh material from premature drying using appropriate curing method e.g. curing compound, moist geo-textile membrane, hessian, polythene sheet, etc.
CLEANING OF EQUIPMENT
Clean all tools and application equipment with water immediately after use. Hardened/cured material can only be mechanically removed.
