MIXING
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 15-20oC.
Water addition per 25kg bag
| Pourable consistency | 3.75 litres |
| Flowable consistency | 4.25 litres |
| Fluid consistency | 4.75 litres |
Place the water into a forced action grout mixer or in a clean drum. Slowly add complete bag of Sika® Armorex® L2 High Flow into the water and continuously mix for 3 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.
APPLICATION
Immediately after mixing, pour the mixed grout into the header box/hopper ensuring continuous grout flow during the complete grouting operation to avoid trapping air. Use steel banding or chains to assist flow where necessary. For large volume placement, grout pumps are recommended.
CURING TREATMENT
After the grout has initially hardened, remove formwork and trim edges while concrete is ‘green’. Cure all exposed grout surfaces using Sikafloor® ProSeal. In cold weather apply heat blankets to maintain a constant temperature.
CLEANING OF TOOLS
Clean all tools and application equipment with water immediately after use. Hardened/cured material can only be mechanically removed.
