MIXING
Place 70–80 % of the premeasured clean water (depending on consistency required – refer to “Mix Ratio”) into a clean container and gradually add the whole bag of SikaGrout®-214 MY into it while continuously mixing. Add the remaining water until the desired consistency is obtained.
Mix for 2 – 3 minutes with a low speed drill (500 rpm max.).
APPLICATION
Use SikaGrout®-214 MY for grouting only.
After mixing, stir lightly with a spatula for a few seconds to release any entrapped air. The grout is then poured immediately into the prepared formwork.
When carrying out baseplate grouting, ensure sufficient pressure head it maintained for uninterrupted mortar flow. For formwork repair, the prepared formwork must be firmly in place and kept watertight.
When placing grout over a large area, it is important to maintain a continuous flow throughout. Work sequence must be properly organised to ensure an uninterrupted flow.
For sections thicker than 100 mm or for grouting large areas, it is necessary to mix SikaGrout®-214 MY with graded 10 mm silt free aggregates to minimise temperature rise generated during curing stage. The quantity of aggregates should not exceed 1 part aggregates to 1 part SikaGrout®-214 MY by weight. Other precautions such as the use of chilled water, insulation of the formwork or baseplate may be required. Please consult our Technical Service Department for assistance.
To further ensure that air entrapped during mixing is allowed to fully escape, it may be necessary to make breather holes. Use steel rods or chains to assist the flow of grout where necessary.
CLEANING OF EQUIPMENT
Clean all tools and application equipment with water immediately after use. Hardened or cured material can only be mechanically removed.
