Topflow Screed C is a fast drying, cement based, free flowing liquid screed that can be trafficked after just 24–48 hours and dries within 21-28 days, providing flexibility in installation and the overall build program. And because it is a cement-based product, it is compatible with most cement based adhesives and floor leveling compounds.
Combining the ease and speed of application of a flowing anhydrite-based screed with the key properties of a traditional dry cement based screed, Topflow Screed C also provides the benefit of reduced drying times.
The range now includes Topflow Screed C Cure a cement based liquid screed with an integral curing agent to control drying and eliminates the need for sprayed application of a moisture suppressant; for fast, efficient completion and even curing along with the same rapid drying times.
