Free flowing Topflow Screed A can be laid in areas of up to 2000m2 in just one day. It is suitable for foot traffic within 24-48 hours while partitions can be erected just seven days after placing.
Stronger than sand cement screed, Topflow Screed A requires no reinforcement and no manual compaction.
New build and renovation work. Unbonded, bonded or floating construction. Residential and commercial. With or without underfloor heating. Whatever the requirement, Topflow Screed A gives you greater project flexibility
Topflow Screed A is less prone to shrinkage than sand cement screeds and therefore requires fewer construction joints.
Topflow Screed A doesn’t contain any cement and has an overall recycled content of 36%.
Tarmac’s Topflow Screed A Sky is a blend of synthetic calcium sulphate binder, selected aggregates, special additives and clean potable water, to produce a pumpable self levelling, flowing screed manufactured to BS EN 13813:2001.
When a client refurbishing their property wanted to improve not only the quality of the finish of their floor but the overall standard of it’s thermal co-efficiency too, Topflow Screed A Thermio provided the solution.
The floor in 2 classrooms at Coed-Y-Brain was ingressing water and a solution needed to be found.
Free-flowing for faster installation
Topflow Screed A is made with a recycled source of gypsum (calcium sulphate) rather than cement. It has a free-flowing fluid consistency and is applied by pump.
Floors are suitable for foot traffic within just 24-48 hours, while drying takes just 40 days, or sooner with force drying (available after only 7 days). Typical drying times are 1mm per day for depths of 40mm and 0.5mm per day for depths above 40mm.
More benefits. More applications.
Topflow Screed A is perfect for a wide range of applications. Its high thermal conductivity and minimum thickness make it ideal for use with underfloor heating. Furthermore, because it’s free from protein and doesn’t harbour potentially harmful bacteria, it’s also the natural choice for hospitals and care homes.
