This was so that if I missed any spots when painting it, or if some of the patina gets knocked off somehow, I won’t be left with a glaring white patch. I used fleur-de-lys mouldings in the brown colour (which is a pigment added when I mix the resin) to demonstrate these processes. Make sure you dry the last coat properly, and stir the paint very well between coats as the metal powder may have sunk to the bottom.Ī with any paint project, you’ll need to prepare your surface well. It’s also not a huge problem if your paint is a bit runny – you’ll just have to add more coats until the project is well covered. Cracks will just add texture to the final patina. The first coat probably won’t cover well, so you’ll need a second coat anyway. It’s not the end of the world if it cracks. Mine was about the consistency of double cream. The consistency of the paint should be fairly fairly thick, but not tick enough that it cracks on the project when it has dried. And voila! You have just made your own DIY Patina Paint! Pretty easy, huh? Step 3 – Mix the powder and medium together well. PVA is quite thick and sticky, so you will probably need to water it down a little. The ratio needed will depend on the binder you use. Step 2 – Measure your binding medium into a cup. If in doubt, mix a small amount to begin with – you can easily mix more. The amount you will need will depend on the size of your project. Step 1 – Measure out the powder into a cup. A clear, water based medium, such as acrylic glaze, a pouring medium, water based varnish or you an even use a PVA glue such as Mod Podge.Metal Powder of your choice – 10 parts by weight.How to Make DIY Patina Paint using Metal Powders The colour and texture can depend on the chemical used, the metal, how long the chemicals have been in contact with the metal, and the temperature. Some chemicals can accelerate the oxidation alongside other chemicals. Patination and rusting are, at it’s simplest, the result of oxidation of the metal. Never, ever mix ammonia and bleach, vinegar and bleach, or Isopropyl (or Rubbing) Alcohol and bleach. Never mix chemicals unless you know what you are doing. In addition, make sure you handle the chemicals used to patina the metals in a very well ventilated space, and wear skin, lung and eye protection at all time. Metal Powders should not be inhaled or ingested, so please make sure you wear appropriate PPE. I decided to use four metals that are most commonly used when fabricating household decor: Bronze, Iron, Copper and Brass. For the sake of this blog, though, I thought it would be more fun – and accessible – to explore what household chemicals can do to create patinas. My research proved that there are so many different ways to produce sometimes surprising colours. Not to say I have delved into this widely as yet. It’s fascinating how you can achieve different colours using different chemicals. Chemistry truly is one of nature’s decorators. I love seeing a plain, boring, dull bit of metal transform into something beautiful. I’ve been experimenting with how to patina using DIY patina paint and household chemicals, and I have to say, it’s absolutely fascinating – and fun!
