How to mix UltraFloor Fill IT Flowable Bulking Concrete

  • UltraFloor Fill IT can be mixed mechanically or by hand. If by hand, ensure that the mixing is vigorous.
  • Mix the inner bag containing the cement with the sand/aggregate.
  • UltraFloor Fill IT is formulated to be mixed to a smooth flowable consistency.
  • It is advisable to add a maximum of 1.25 litres of water initially, mix and if required, add up to a further 0.25 litres up to max of 1.5 litres per 25kg bag.
  • It is essential that this product not be over-watered. The addition of excessive water will result in slower strength gain, reduced final compressive strength and the possibility of shrinkage cracking.
  • Sand/aggregate contains moisture and the volume of water required will vary depending on the moisture content of the aggregate.
  • Mix only enough material to apply within 4 minutes. Never remix or add water.

How to apply UltraFloor Fill IT Flowable Bulking Concrete

  • UltraFloor Fill IT should be poured into place to achieve the required depth, prior to application of finish surfaces.
  • The self-compacting nature of UltraFloor Fill IT allows placement without the need for trowelling.
