TOPFLOW SCREED A
The ultimate free-flowing floor screed
It’s a common problem; time is tight yet the project requirements are many. You need a flooring solution that is both fast and flexible, one that is simple to place providing a high quality surface. Ordinary sand cement screed does not deliver the speed or the versatility. But there is an alternative that ticks all the right boxes, Topflow Screed A from Tarmac.
Topflow Screed A made with a unique synthetic anhydrite binder in place of cement is pump applied due to its fluid consistency. This means that it is easier to lay covering areas of up to 2000m2 in a day. It is thinner than conventional screeds making it the natural choice for underfloor heating systems.
Our Topflow Screed A solutions are part of our wider range of flowing screed solutions. We also offer a cement based free flowing screed – Topflow Screed C Belitex. Read more about this alternative.
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.
