Flowpoint Smooth: Rapid Set Flowable Grout

Application

  • For all pavements where a rigid or bound void-free joint is required.
  • The product is suitable for application in town centre pedestrian schemes, pathways and carriageways, and can be used with natural stone, concrete flags and clay paviours.

Description

UltraScape Flowpoint Smooth is a fully pre-mixed dry-pack which only requires the addition of water on-site. It can fill joints from 3–50 mm wide with a minimum target depth of 20 mm, up to 200 mm in one application. This highly fluid grout achieves a final compressive strength of 49.6 N/mm² (results achieved using 4.25 litres of water per 25 kg bag), and will reach initial set in 30 minutes, will accept light foot traffic after one hour, and vehicular traffic after four hours (dependent upon temperature).


Features and benefits:

  • Provides a seamless surface.
  • Open to foot traffic in one hour.
  • Open to vehicular traffic in four hours.
  • Rapid setting.
  • Exceptional bond strength.
  • Shrinkage compensated.
  • Mixes quickly on-site with water.
  • Initial set after 15 minutes at 20°C.
  • Economical to use.
  • Conforms to BS 7533.
  • Ideal for large-scale projects.
  • Part of the UltraScape streetscape system, which guarantees compatibility.
