Mordant Solution (T Wash)

Surface Preparation
To get the best results, clean down using an abrasive pad, water and cleaning agent
followed by rinsing and allowing to dry. Ensure surfaces to be painted are sound, clean
and dry (new surfaces particularly must be fully dry) and free from all defective or
poorly adhering material such as dirt, grease and oil. Universal degrease where
necessary with a suitable oil and grease remover. Rinse with clean water to remove
residues.

Mixing
Shake the solution in the container for approx 30 seconds ensuring the cap is tightly fastened.

Application
Can be applied by brush 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. Leave on the surface for about 15 minutes – 1 hour then rinse with clean water to remove acid residues.

Subsequent Coat
The pre-treated surface should be overcoated with an appropriate metal primer
within 48 hours or before contamination can recur
