Whether you refurbishing or having a new build there are a few avenues to discover when it comes to floor screeding. The traditional way is the sand and cement mix which is mixed in a cement mixer then barrowed in and laid by hand with the aid of an aluminium box section after bands created on the perimiter of the room to keep the floor level, if its going onto an existing concrete slab the surface needs to be dustless and coated with SBR, to achieve the final finish the laid screed floated with a polyfloat then closed in with a screeding trowel. The traditional screed`s drying time is 1mm per day, to speed up the process accelerator can be used, the usual minimum thickness is 30mm, can be laid over UFH. This traditional mix can be obtained from your local concrete plant, this assures that the mix is consistent.
These days, anything over 40sqm floor area the liquid screed is a viable option, this gets delivered onto site by a mixer lorry and the screed pumped in with a diesel machine, following the pour a dapple bar placed over the screed to level and minimize the air bubbles in the mix, this method is very rapid, 1000sqm can be laid in a day. Curing time is very rapid, this screed can bear foot traffic the following day, which enables trades to carry on with other tasks. Liquid screed can be laid over UFH, from a thickness of 35mm, there are a wide variety of brands and uses out there.
