Product Description
Mordant solution is a T wash galvanised steel metal wash that contains a reactive chemical solution used as a pre-treatment for galvanised surfaces which aids the adhesion of subsequent coats of paint. Supplied as a blue solution that has a characteristic blackening effect on the galvanised surface. This helps in indicating that the treatment has been effective.
- Formulated to a British Rail T Wash galvanised steel specification
- Mordant solution is an excellent metal wash for the pre-treatment of galvanised steel and zintec sheeting prior to painting
- Once treated, a wide selection of paints can be applied.

It at first appeared to be an unnecessary extra cost and processes. However, having previously experienced paint blistering reactions having painted directly onto what I thought were well seasoned galvanized surfaces even using the recommended primer undercoat and process.
Applied this around 5 months ago in a 3 stage Mordant, Primer then Topcoat process and is looking good against a comparable now blistering primer/ topcoat without Mordant solution.
Its a major costly job trying to sort out paint problems. Fortunately for me this time its only on a small comparison test area this time.
