DIRECTION FOR USE
Preparation:
The surface onto which the grout is to be applied should be scabbled to remove laitance and expose aggregate. Do not use bush hammers or similar preparation equipment that can crush the aggregate but leave it in place. The surface must be free of oil, dust, dirt, paint, curing compounds or other contaminants that could impair adhesion. Soak area to be grouted to minimize absorption. Surfaces should be damp but free of standing water. Particular attention should be paid to bolt holes to ensure that these are water-free. Use oil free compressed air to blow out bolt holes and pockets as necessary.
Base plates, bolts, etc. must be clean and free of oil, grease and paint. Set and align equipment. If shims are to be removed after the grout has set, then lightly grease them for easy removal.
Ensure formwork is secure and watertight to prevent movement and leaking during the placing and curing of the grout.
Mixing:
Damp down the inside of the grout mixer with water prior to mixing the initial batch of RB-RG. Ensure the mixer is damp but free of standing water. Add the pre-measured quantity of water. Slowly add the RB-RG, mixing continuously. Mix for 3-5 minutes until a smooth, uniform, lump free consistency is achieved.
Placing:
Place immediately after mixing, into the prepared area in such a manner that the grout has the shortest distance to flow. Pour the grout continuously maintaining a constant hydrostatic head wherever possible. RB-RG grouts are suitable for use with most types of pumping equipment. Immediately after RB-RG grout is placed, cover all exposed grout with clean wet hessian and keep moist until grout surface is ready to be finished, or until final set.
STORAGE
Store out of direct sunlight, clear of the ground on pallets protected from rainfall. Avoid excessive compaction. Storage life is approximately 12 months when stored in ideal conditions in original sealed bags.
Precautions
The temperature of both the grout and elements coming into contact with the grout should be in the range of +5°C to +35°C. Do not use water in an amount or at a temperature that will produce a consistency more than flowable or cause mixed grout to bleed or segregate.
RB-RG should be laid at a minimum thickness of 10 mm and to a maximum depth of 150 mm.
It is essential that a mechanically powered grout mixer is used to obtain the optimum properties. A slow speed drill and mixing paddle may be used for single bag batches only.
SAFETY
As with other products containing Portland cement, the cementitious material in RB-RG grout may cause irritation. In case of contact with eyes, immediately flush with plenty of water for at least 15 minutes. Call a physician. In case of contact with skin, wash skin thoroughly.
