A good screed construction is the foundation of a good floor installation – and, in today’s climate, high performance and speed of application are essential. In response, Mapei has developed a range of rapid-drying screeds that perform to the highest technical standards in fast-track installations, whilst also providing a safe and sustainable application.
To speed up moisture evaporation in Portland cement-based screed, Mapei has formulated a special binder which incorporates admixtures in powder form. The binder reduces the amount of mixing water needed, increases mechanical strength and reduces shrinkage and drying time. Products featuring this technology include Mapei’s best-selling EMICODE: EC1 Plus-certified Topcem and Topcem Pronto.
More about Topcem & Topcem Pronto
Mapei Topcem is a specialist hydraulic binder for normal setting, fast-drying and shrinkage-compensated screeds. It can be used to form bonded, unbonded, floating screeds – including those with piped underfloor heating – on new and existing concrete prior to floor installation – inside and outdoors. Mapei Topcem Pronto is the ready-mixed, rapid-drying formulation with high thermal conductivity, ideal for heated screeds.
Both screeds set to light traffic after 12 hours. Ceramic tiles can be laid after 24 hours, natural stone after two days and, within four days, the finish is completely dry and can accept moisture sensitive floorcoverings, including resilient and wood flooring. In addition to new applications, Mapei Topcem and Topcem Pronto are also ideal for patching, repairing and time-sensitive screed replacement.
