how to apply dacrylate mordant solution
Apply T-Wash sparingly ensuring the substrate turns and remains black when dry.
Care must be taken not to apply excessively
This material should preferably be applied at temperatures in excess of 10°C. Relative humidity should not exceed 90% and in these conditions good ventilation is essential.
Substrate temperature should be at least 3°C above the dew point and always above 0°C. At application temperatures below 10°C, drying and curing times will be significantly extended.
Clean-up: Clean all equipment after use with Dacrylate Thinner water. All surplus product should be disposed of in accordance with appropriate regional regulations/legislation.
Brush application: Apply by brush to clean degreased surface and allow to dry.
Avoid excess application and ‘ponding’. After drying, excess T-Wash should be wet-cleaned and remove surplus T-Wash and allow to dry.
When dry, the galvanised surface should be ‘blackened’.
Any areas still showing a bright galvanised surface indicates presence of contamination.
Lightly abrade these areas, degrease and re-apply Mordant Solution.
On weathered galvanising the appearance after treatment may vary from Black to Light Grey.
