FIBRES Surescreed Fibre incorporates a high performance polypropylene micro-fibre. These fibres are evenly dispersed throughout the screed in a 3 dimensional system and help to reduce plastic shrinkage cracking. Surescreed Fibre will also exhibit improved impact and abrasion resistance. T: +44 (0)28 9085 1441 E: [email protected] W: www.rtu.co.uk RTU Ltd, Cloughfern Avenue, Newtownabbey, Co. Antrim, BT37 0UZ TECHNICAL INFORMATION Density 1800-2100kg/m3 Strength Classification @ 28 days: Surescreed C12 – F3 Surescreed HD C20 – F4 DRYING Surescreed should be allowed to cure for 7 days when moisture loss should be prevented. After 7 days the screed can then be allowed to begin the drying process. The screed will dry at 1mm per day for the 1 st 40mm, ½ mm per day for the next 40mm and then ¼ mm per day for the next 40mm at ambient conditions of 20ºC and 65% relative humidity. The screed will take longer to dry in poorer drying conditions. Surescreed should not be forced dried as this will cause increased risk of cracking.
