Johnstone's Trade Mordant Solution is a pre-treatment solution for galvanised steel which converts the surface nature to ensure the subsequent adhesion of a wide range of top coats.

How to apply Mordant Solution

Thoroughly work the mordant solution into the surface with a brush ensuring the surface changes colour completely (blackens). If the colour change doesn't occur completely, a second application may be needed.

Customer Questions
can mordants be used to give zinc a dark finish
Mordant solution is a cleaning agent for steel rather than a finish, it can be used to wash the surface before painting but won't have any impact on the colour it is painted afterwards.
Will mordant solution damage grass?
Yes, mordant solution could kill or burn grass. If you are applying it to a surface over grass, we recommend laying dust sheets underneath to protect it.
