Mordant solution for Galvanised Steel 500 ml 
Apply to new galvanising within 7 days. Zinc surfaces which are contaminated should be cleaned down using an abrasive pad, water and cleaning agent followed by rinsing and allowing to dry. If contaminated with oil or grease surfaces should be wiped over with Universal Degreaser before carrying out the cleaning down procedure. Can be applied to weathered galvanised surfaces although reactivity of the treatment will diminish as the age of the galvanising increases and can result in an uneven colouration from light grey to dark grey. If no colour change take place, these areas should be considered as contaminated.

paper. Remove all residues and re-apply, Avoid over-application

of a fine brown deposit of copper. 
After treatment the surface must be rinsed with 
clean water to remove all residues and then 
allowed to dry before priming.

with an appropriate  metal primer 
within 48 hours or before contamination can
