Mordant Solution T-Wash Pre-Etch Primer, 1 Litre | For Galvanised Metal, Chemically Pre-Treats Galvanised Steel, Preparation for Painting or Patina Effects

Good quality item, cleans well and does exactly what you would expect.

So I applied to weathered galvanized metal as if it's glav' I don't really have a reason to paint that, although I can understand why someone may wish to. The metal did indeed blacken, I left this overnight and I was pleased with the result as I could see a reaction had taken place. I think for lifting something after weather and age has taken it's toll this is going to be useful to have to hand.

Excellent product in a small quantity, galvanised steelwork prepared for painting

This stuff came with a page of instructions which were concise but clear. I thought I had followed them pretty well but it became apparent that the galvanised tube I was applying the solution to was not properly cleaned. When I brushed the solution on it was very obvious that I hadn't done a good enough job preparing the surface. It must be as free from any oil, grease or other contaminants as you can possibly get before you apply it. Get that part right and it works very well. My ONLY issue is that I wish they sold it in smaller quantities because you really don't need much if you do the prep right.

This product is definitely one of the best I've tried. It provides the desired results quickly and efficiently. The packaging is also very simple and easy to use. I highly recommend this product to anyone looking for a reliable and effective solution.

Not so good in chemical reaction, but works, just needs time to stay on the metal...

Good quality

The Mordant Solution T Wash is an effective and reliable solution for preparing new galvanised metal surfaces prior to painting and priming. It's essential to prepare galvanised metal surfaces properly, especially if you want to achieve a long-lasting, professional-looking finish. This solution is perfect for achieving just that. There are several ways to prevent iron and steel from rusting, but essentially, you need to prevent oxygen or water from reaching the surface of the metal. Painting, oiling, or plating can all achieve this, but the Mordant Solution T Wash takes it a step further by chemically pre-treating galvanised steel surfaces. The Mordant Solution T Wash is an acidic solution of a copper salt, specially formulated for the pre-treatment of clean zinc surfaces. It provides an excellent key for paints that would otherwise show poor adhesion, making it an essential solution for achieving a high-quality finish. Not only can it be applied to new galvanising for better adhesion, but it can also be applied to weathered galvanising. Metals exposed to the elements will oxidise and corrode much faster than protected metals. Galvanising is the best solution for corrosion protection, offering significantly greater benefits than paint or any other coating system. The product comes in a 1-litre bottle and can be applied using a brush or spray (use meagrely). The solution changes colour from grey to black for a visual aid and proof that the entire surface has been treated satisfactorily. The Mordant Solution T Wash is used extensively in industry throughout the UK, trusted by powder coating services. The formula is full strength chemistry, ensuring economical usage and proper functional outcome. It can even be used to add patina effects to wrought iron work during manufacture, giving a pleasing aged look and tonal values. Overall, the Mordant Solution T Wash is an excellent product that can help you achieve a professional-looking finish on your galvanised metal surfaces. It's easy to apply, effective, and versatile, making it an essential solution for anyone who wants to achieve a high-quality finish on their metal surfaces.
