Sika SikaGrout 212 is a one part flowable shrinkage compensated cementitious grout for interior and exterior use.
Sika SikaGrout 212 is ideal for general purpose grouting under stanchion plates or machine & base plates. Sika SikaGrout 212 is also suitable for filling cavities, voids, gaps and recesses, general concrete repairs and steel reinforcement anchoring. Formulated for exterior and interior use.

Concrete, mortar, stone Preparation:
Surfaces must be sound, thoroughly clean, free from ice, oils, grease, standing water and any loose or friable particles and any other surface contaminants. The concrete “pull off” (tensile) strength should be > 1.0 MPa.
Steel, iron Preparation:
Clean, free from oil or grease, rust and scale etc.
All formwork should be of adequate strength, treated with release agent and sealed to prevent leakage. Sealing can be achieved by using Sikaflex® -11FC+ sealant
beneath or around formwork and between joints. Ensure formwork includes outlets for extraction of the pre-soaking water. A header box/hopper should be constructed on one side of the formwork so that a grout head of 150-200 mm can be maintained during the grouting operation.
The substrate should be prepared by suitable mechanical preparation techniques such as high pressure water jetting, breakers, blastcleaning, scabblers, etc. The concrete substrates should be pre-soaked with clean water continuously for 2 - 6 hours to ensure a saturated surface dry condition throughout the operation. Immediately before pouring grout, remove all excess or standing water from within any formwork, cavities or pockets.
Measure the appropriate amount of water to achieve the desired grout consistency given in the table below. Heat water if necessary to achieve a temperature between 15-20°C. For a 25kg bag, add 2.3 - 3.9 litres of water for a pourable, flowable consistency. Mix for 2 minutes minimum.
Place the water into a forced action grout mixer or in a clean drum. Slowly add complete bag of SikaGrout® 212 into the water and continuously mix for 2 minutes
in mixer to achieve a uniform and lump free consistency. Alternatively use a slow speed drill (200-500 rpm) and helical mixer. Dependent on the desired consistency and flow properties, the mixing ratio can be adjusted.
After the grout has initially hardened, remove formwork and trim edges while concrete is ‘green’. Cure all exposed grout surfaces using Sikafloor® ProSeal.
