Ultrascape Flowpoint - Rapid Set Flowable Grout

A rapid setting flowable grout that exceeds the requirements of BS 7533. With a proven track record spanning over 25 years, Flowpoint has met demands in both heavily trafficked and domestic paving environments long before the British Standard was introduced. It is fast and efficient to apply, affording the ability to grout large areas of paving quickly and cleanly, meaning areas can be open to foot traffic after just 1 hour
