CL 11 has been especially designed to produce a smooth, flat surface when applied to hard, rigid sub-floors such as sandcement screeds, concrete, etc.
CL 11 contains high quality special cements and selected fillers so that, when mixed with water, a fluid easily trowelled mortar with free-flowing properties is produced. The mixed mortar can be applied up to a maximum thickness of 5mm in one application but will more normally be applied at 3 - 5 mm.
