Teamac Mordant Solution (T-Wash) 2.5L is a single-pack etching agent designed to improve paint adhesion on new and weathered galvanised surfaces. The solution reacts with zinc, creating an adhesive surface that allows paints to adhere more effectively. Its blue colour changes to grey, indicating the surface is ready for painting.

Application Usage

• Suitable for new or weathered galvanised surfaces.
• Should be applied within seven days of galvanising for best results.
• On older galvanised surfaces, reactivity may vary, leading to uneven coloration.
• Apply only to clean, degreased surfaces?contaminated areas may require additional cleaning.
• Do not recoat treated surfaces?this solution is a single-use treatment.

If the colour does not change to grey, this indicates contamination, and further surface preparation is required before painting.

Surface Preparation

• Remove oil, grease, and dirt using a universal degreaser.
• Use an abrasive pad with water and a suitable cleaning agent to prepare the surface.
• Ensure thorough drying before applying the solution.

Failure to prepare the surface properly can lead to poor adhesion and reduced paint performance.

Limitations Recommendations

• Do not use on non-galvanised surfaces.
• Avoid areas where material build-up may occur.
• Not suitable for highly contaminated or unclean surfaces without additional treatment.

Health Safety

• UN Number: 1219 ? classified as flammable.
• Contains propan-2-ol and orthophosphoric acid, which can cause serious eye and skin irritation.
• Always wear gloves, safety glasses, and ensure ventilation during use.
• Avoid direct contact with skin and eyes?rinse immediately with water and seek medical attention if necessary.
