HIGHFLOW RAPIDE Highflow Rapide is a self-compacting, and by dappling self-smoothing, faster drying floor screed for placing by pump or chute, providing contractors and specifiers with a high performance fast track solution to the construction of screeded floors. Highflow Rapide is a unique and highly innovative faster drying screed which uses high quality Gypsol anhydrite, specially graded sands and selected additives to create a free flowing self-compacting floor screed which dries in a fraction of the time taken for more traditional anhydrite or cementitious screeds. This allows the user to install floor coverings in significantly less time than for competing screed systems. Highflow Rapide is self-curing and requires no artificial curing membrane after installation. The dimensional stability of Highflow Rapide, whether heated or unheated, significantly reduces the risk of cracking without the need for reinforcement and with much larger bay sizes when compared to cement based materials. FEATURES & BENEFITS: apid installation – up to 2000m2 per day. Allows reduced R programme time apid finishing – no spray-on curing membranes reducing R airborne contamination and eliminating associated safety issues apid strength gain – no reinforcement or fibres required R and fewer joints with much larger bay sizes apid setting – allows early foot traffic R apid return to full service – can be loaded after just 7 days R apid thermal response – enables greater efficiency of R underfloor heating systems apid completion – allows early floor covering application, R e.g. in as little as half the time when compared to other standard anhydrite screeds APPLICATIONS Highflow Rapide can be used in all construction types including traditional masonry, lightweight steel frame, timber frame and in high strength applications. Highflow Rapide can be used with or without underfloor heating to create a highly energy efficient heating system. INSTALLATION & MAINTENANCE Highflow Rapide screed should only be installed by suitably trained and qualified installers who hold a certificate of attendance for the Gypsol Rapide training course. For best results Highflow Rapide screed should be placed and finished within 2 hours o

CONCRETE PRE INSTALLATION The building should be weather tight with all external windows and doors in place or openings fully secured against the ingress of water as this can extend the drying time of the screed. Standing water, on any membrane needs to be mostly removed. The area to be screeded should be fully prepared with a Damp Proof Membrane (DPM) between the screed and the subfloor. This would normally be in the form of a 1200-gauge polythene membrane over the top of concrete. This applies to all ground floor substrates as well as concrete and beam and block separating floors. Where timber...

CONCRETE POST INSTALLATION Once the screed is poured and finished throughout the work area, the area should be sealed to prevent access to foot traffic for a period of 24 to 48 hours. After 48 hours the screed should be well ventilated by opening windows and doors as much as possible. Note that trickle vents in window frames are unlikely to provide enough ventilation. The anticipated drying time for 50mm of Highflow Rapide screed correctly placed and in good drying conditions is 14 days from installation. Optimum drying conditions include warm dry air at or above 20oC and low relative humidity...
