Calcium sulphate flowing screeds have been gaining rapidly in popularity over the last few years as their many benefits over and above the traditional sand and cement mix have become apparent. They are very easy to lay because instead of being trowelled on to the substrate by hand, they are pumped on to it using a long hose attached to the delivery truck. In fact, it is calculated that a flowing liquid screed can be laid as much as 20 times as fast as sand and cement. <br><br>

In fact, it is calculated that aflowing liquid screed can be laid as muchas20timesasfastassandandcement. The liquid screeds that we supply at UKScreedsare made using calcium sulphate as the binder instead of cement, and they are also known as anhydrite screeds becausethecalciumsulphateisanhydrous–i.e.dry.
Wheninstallingunderfloorheating,a traditional screed needs to be at least 75mm thick,andmaybeasmuchas100mm.By contrast,whenusingaflowingscreedin Winchester,weonlyneedtocoverthe heatingpipesto adepth of 30mm,making 45mm in total. So,although the cost of the material isaround double that of sand and cement, we don’t need to use nearly so much ofit.
Thisalsoreducestheoveralldryingtime.Our screeds are calculated to dry at a rate of 1mm per dayup to adepth of 40mm and ½mmper day thereafter, so a depth of 45mm will take 50 days to dry. That isalot faster than asand and cement screed of 75mm or more. However, in practice the dryingtimesofbothwilltakesomewhatlonger because the figures are calculated on the basis that thetemperatureisat20°Candtherelative humidity no greater than 65%.
