Johnstone's Trade Mordant Solution is recommended as a pre-treatment for galvanised steel to ensure adhesion of subsequent topcoats.
Ensure all oil and grease is removed from the surface to be treated by using Johnstone’s Cleaner & Degreaser. Allow the surface to dry before application of the subsequent coating.
Thoroughly work Johnstone’s Mordant Solution into the surface using a brush ensuring all the surface changes colour (blackens). If no initial reaction takes place, then a second application may be required. Rinse with clean water and allow to dry.
