INTRODUCTION
Cureflex® SD35 is a commercial grade, cementitious, premixed screed. The formula contains polymers, recycled natural and acrylic fibres as well as additives that allow for the formation of thin screed beds without shrinking or cracking.
Designed to be as multi-purpose as possible, Cureflex® SD35 can be used both internally and externally for forming shower bases, adjusting floor level heights or creating falls for drainage.
Cureflex® SD35 has been specifically engineered to withstand structural movement and cracking. The screed provides impressive compressive and flexural strength yet remains easy to mix, trowel and clean.
