Use This With

Mordant Solution :- is a Pre-treatment for galvanised steel which converts the surface nature to ensure the subsequent adhesion of a wide range of coatings. Use by thoroughly working Johnstone's mordant solution in to the surface using a brush, ensuring all of 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. Please download the manufacturer's data sheet for full details.
