Teamac Marine Mordant Solution 2.5L

What is Teamac Mordant Solution?

Teamac Mordant Solution, also known as "T-wash," is a pre-treatment solution designed to chemically etch galvanized steel surfaces. It creates a suitable surface for better adhesion of subsequent paint layers, particularly primers and topcoats.

Why do I need to use a mordant solution on galvanized steel?

Galvanized steel has a smooth, oily finish that makes it difficult for paint to adhere. The mordant solution reacts with the zinc coating, creating a rougher, darker surface (usually turning black or dark grey), which improves the bond between the metal and paint.

How do I apply Teamac Mordant Solution?

Apply the solution using a brush or dipping, ensuring the entire galvanized surface is evenly coated. Allow the solution to react with the surface and wait until it changes colour (typically darkens). Once dry, the surface is ready for painting.

How long does Teamac Mordant Solution take to work?

The mordant solution usually takes about 30 minutes to 2 hours to fully react and turn the galvanized surface a darker colour. The time may vary depending on the surface and environmental conditions.

Can I use Teamac Mordant Solution indoors?

Yes, Teamac Mordant Solution can be used indoors, but proper ventilation is important due to the fumes. Always follow safety guidelines, including using personal protective equipment (PPE), such as gloves and goggles.

What happens if the surface doesn’t change colour after applying the solution?

If the surface doesn’t change colour, it may indicate that the galvanizing is too new, or the surface is too oily or greasy. In such cases, it's essential to clean the surface properly with a degreaser before reapplying the mordant solution.
