1. What is Teamac T-Wash used for?

Teamac T-Wash is an acid-based mordant solution specifically formulated to etch zinc and galvanised steel, creating a surface that helps paint or primer adhere more effectively. It’s ideal for industrial, commercial, and exterior projects where poor paint adhesion is common.

2. How do I apply T-Wash to galvanised steel?

You can apply T-Wash by brush, dip, or roller. Ensure the galvanised surface is clean and free of any oil, grease, or dirt beforehand. After treatment, rinse if recommended, allow it to dry, and then follow up with your chosen paint or primer.

3. Does it need to dry before painting?

Yes. Allow the solution to react and etch the surface. Once it has finished etching and is completely dry, you can apply your paint or primer directly. Refer to the product instructions for specific timing guidelines.

4. Can I use T-Wash on previously painted or rusted surfaces?

It is best used on new or lightly oxidised galvanised steel. If surfaces are painted or heavily rusted, remove loose paint or rust first. In these scenarios, a different preparation method or product may be required. Check with our experts for guidance.

5. Will this product damage the metal?

No. When used as directed, Teamac T-Wash provides a controlled etching that improves paint adhesion without damaging the underlying galvanised layer. Always follow the instructions carefully, and wear appropriate protective equipment.

6. What coverage can I expect?

One litre typically covers about 40 m², although coverage may vary depending on the substrate’s texture and cleanliness. Applying it evenly ensures you get the best adhesion results for your subsequent coatings.

7. Is it safe to handle?

Teamac T-Wash is an acid-based solution containing copper salts, so it’s essential to use personal protective equipment (PPE) like gloves and safety glasses. Follow the safety guidelines on the product datasheet for storage, handling, and disposal.
