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. Spray polyurethane is the top coat of mild steel, two coats is bestĪ hard paste wax is applied over all the other sealers, this is totally waterproof and can be reapplied as often as desired or needed.Ī hard paste wax is the final step n the bluing and finishing process.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! ![]() Two coats area applied and let dry for some time, one final step is all the remains. ![]() Next and finally when the Penetrol is hard a polyurethane spray is used on the exterior surface. My favorite first layer of sealer to protect blued mild steel, Penetrol ![]() This is actually a paint thinner used for oil paint, but applied to steel and given plenty of time to dry acts as a nice hard seal for the surface. Penetrol is the first of two sealers I use to finish steel and make it ready for use. Rub the newly blued metal surface for a lustrous sheen which will next be sealed Rub the newly blued surface after it is totally dry with steel wool, this helps to blend away any streaks or blemishes.Ī metalworkers friend, 0000 steel wool. Let this set for a short time and dry the steel with a clean rag.Ī sweet "blued" surface after chemical treatment, a rich color hides all the sanding and grinding marks, almost ready to finish The chemical step is pretty easy, after the form is cleaned and ready you apply the bluing agent (I use Instablack) to patina the steel. Many chemicals and process involve pollution and carry long term cumulative health risk, always protect your lungs, eyes and skin. Second part involves chemicals, don't forget your gloves and mask. Using a chemical "bluing agent" the surface of the steel is colored, this is a permanent process and will last many years if sealed properly Some chemical and some physical procedures will to be outlined and my personal process exposed.įabricating your object is the first step, cut, weld, grind and or form the work to specs, then when item is ready the finishing process begins.īuild your object, grind, sand and shape the piece reading for finish This process is fairly easy but all the steps need to be followed and correct materials used. I wanted to outline the steps in creating a beautiful finished surface on a mild steel item.
