Mastertop 538 

Mastertop 538 is a self-smoothing, cementitious, non-structural, floor overlay for re-levelling and refurbishing cementitious based floor slabs.  Mastertop 538 can be laid at thicknesses from 3 mm when hand applied or 6 mm when pump applied, maximum 15 mm.  Mastertop 538 simply requires a protective coating over the cured system and is used only as underlayment application.
