John Carr (Liverpool)Ltd floor screeds are mixed in a forced action mixer,
that ensure all the constituent parts are dispersed evenly throughout the
batch, minimising the risk of agglomerates or balls of cement which frequently
occurs when using free fall mixers.
The sands used in John Carr floor screeds ensure excellent working properties
as well as good strength and durability.
Cement setting times can be retarded from 6 hours, up to24 hours to allow the
screed to be laid over a specified period of time.
Higher performance and modified screed are available. The addition of 6mm or 10mm
aggregate, and admixtures such as polypropylene fibres, S.B.R., Rapid Drying (HES) as
well as the more traditional granolithic screed, give a wide selection of properties
available with John Carr factory made screeds
