Fast drying screed allows for rapid drying of the screed. It can receive foot traffic earlier, floor finishes can be laid sooner, underfloor heating can be commissioned quickly and it will reduce your overall build time. Especially important to consider using it when laying a wooden or engineered floor, as these are the most sensitive to damage by moisture. Standard screed drying times are approx. 1mm a day and a standard depth of screed is usually dry to receive floor finishes in approx. 4-6 weeks. Compared to this, rapid drying screeds can speed up the drying time to hours.
Fast setting screed normally consists of a specialist liquid hydraulic binder that is added to the screed mix or is provided as a pre bagged cement replacer. Both these types promote increased drying times. Differing strengths and types of fast drying additive allow for differing drying times. They also have the benefit of being stronger with higher compressive strengths. Only semi dry screeds can be fast drying.
Fast drying screed is suitable for most floor situations such as over insulation and with underfloor heating. It can receive all types of floor finishes. Accelerated screeds have to be mixed in a screed pump to ensure that the additives are thoroughly mixed. It also has to be batched in stages as the average working time of the mix is approx. 60 minutes.
