Need mordant wash for galvanized steel
2006
For a museum exhibition, I need to replicate / match the surface treatment applied to corrugated galvanized steel sheets. The original work was done in the UK using a product called "T Wash" sold by a company named Decorating Direct, intended as a paint pre-treatment to be brush applied after degreasing and detergent washing.The resulting
'look' is a mottled darkened 'patina' with white streaks.
I can't find an ingredients list for this particular product, but a MSDS for a similar proprietary solution lists 2-BUTOXYETHANOL, PHOSPHORIC ACID, and PROPAN-2-OL.
This type of consumer product seems to be common in the EU countries, but due to a short deadline, I would like to find an equivalent locally.
