If required, Intercromex can be floated to a finish and painted when dry.

It is recommended that Intercromex is cast on or sprayed on. For work on metal lath apply Intercromex as a first coat of minimum 10mm (15mm max.). On precast cement blocks make sure that de-moulding oils are eliminated (if necessary by sanding or high pressure water jet).
