Key Installation Points
FSPG High Strength Compound can be mixed preferably by mechanical paddle or manually if required. Measure out the correct amount of clean water into a clean container to achieve the desired consistency.
(FSPG High Strength Compound: water ratio) Pourable Mix ratio of 3 – 3.5:1 Trowelable Mix ratio of 4:1
Gradually add the FSPG High Strength Compound stirring continually. Continue mixing until the FSPG High Strength Compound is mixed to a smooth even consistency. Any spillage should be wiped up with a damp cloth before setting occurs as it may stain pipes and services. Mix only enough material sufficient for use within the recommended pot life (20-30 minutes). Pot life and set times will be reduced for lower water content and higher temperatures.
Installation should not be carried out when temperatures are above 35oC. Setting times are normally between 30 and 90 minutes. Warning: Do not attempt to extend working time by remixing with additional water once the compound has started to set, as this will interfere with the setting process. Always mix in clean buckets. Using dirty buckets containing remains of compound from earlier mixes may reduce working time.
Fit damming board/shuttering to bottom of opening. Damming materials must be able to support the wet weight of the compound under pouring conditions.
FSPG High Strength Compound must be installed to the required minimum 100mm thickness.
