Preparation: add 4.5 to 5 litres of clean water per bag. Mix Between 3 and 5 minutes maximum.

Protection and curing: do not apply in temperatures below 5oC and above 30oC. Dampen the background to control suction prior to application. Protect against drying wind, rain and strong sun. If necessary cure with light water mist for 2-3 days. Wait 7 days before applying a finishing coat.
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).
