Parex Super FG

LOW TEMPERATURE REPAIR AND IRONWORK BEDDING MORTAR

Parex Super FG is a one component, Magnesium phosphate cement, rapid hardening and high early strength concrete repair and ironwork bedding mortar for use in temperatures as low as 0°C. The resulting mix produces a mortar which gives rapid setting and high early strength properties suitable for works carried out in raising or lowering carriageway frames and covers. Addition of further water will produce a grout.  With the high early strength gain it is ideal for bedding of ironwork, bonding streetscape, flags , blocks and kerbs.

Application steps

MIXING

Excess mixing water should not be used. When mechanical mixing is used wet down the mixing vessel then drain all free water. Add the measured quantity of mixing water. Add the full bag of Parex Super FG. Mix for at least one minute. Suitable mixers include a slow speed high torque drill and Mortar Stirrer.
For mixing at temperatures below +5°C, pre-warm the mixing vessel with warm water and use warm mixing water. Suitable water temperatures are approximately +25 to +30°C.

APPLICATION

Place the mixed mortar as soon as mixing is complete. The chemical setting of Parex Super FG is rapid and all mixed material should be placed within 10 minutes of adding the mixing water.
Set frames by “the drop bed method” or by shimming with hard ceramic tiles to line and level followed by “mortar packing”. The mortar should be fully compacted to obtain maximum strength. In both methods the mortar may be face finished using normal steel trowelling. Once the frame has been set, the outer area can be filled to the required thickness using Parex Super FG as either a grout or concrete mix.

CURING TREATMENT

Finished areas will not normally require curing owing to the rapid setting nature of Parex Super FG. However, where rain, or excessively hot, dry or windy conditions prevail, cover after application using hessian or polythene sheeting taped down at the edges or other approved method.

For cold weather working also use insulation to maintain temperatures. Never wet cure Parex Super FG

CLEANING OF EQUIPMENT

Remove Parex Super FG from tools and equipment with water. Hardened material can only be removed mechanically.
