Each complete 32.8kg pack will yield approximately 16.4 litres of mixed material

Laitance and all loose material including dust, oil and grease should be removed in order to produce a sound substrate. Ensure grouting area is dry.

Substrates must be sound, dry, clean and free from laitance, ice, standing water, grease, oils, old surface treatments or coatings and all loose or friable particles must be removed to achieve a laitance and contaminant free, open textured surface.
Surface and base plate contact area must be clean and sound.

Ensure shuttering is grout-tight and constructed of materials that will not distort during placement. Heavy duty plywood (3/4”) or steel are recommended and will have prolonged working life allowing multiple use.

Ensure that sufficient head is allowed to facilitate continuous discharge and that the gap is not less than 25mm from the edge of the plate. Ensure that the other edges are at least 20mm thick and that the grout is haunched up to level with the top surface of the base plate.

To achieve the most consistent grout mix, mechanical mixing is recommended. Mixing may be carried out in the plastic package pail or a similar suitable mixing vessel. Suitable mixers include a slow speed high torque drill and Grout Stirrer. For full pack mixing of Railfast Grout pour all of the resin contained in the two tins within the pack into the mixing pail. Slowly add the catalysed filler while continually mixing. Continue mixing after all the catalysed filler has been added until the mix is powder free and uniform.
The chemical reaction of setting is rapid. The mixed grout should be placed immediately after mixing. The working time may be extended in cold ambient conditions and may be shortened in hot ambient conditions.

Clean all tools and application equipment with Sika^® Thinner C Cleaner immediately after use. Hardened / cured material can only be removed mechanically.
