Assuming you already have all the items needed, we can get right to the first step of the dyeing process.
1. Get the leather stretched out
What you want to at this juncture is to straighten out the leather. Make sure that there are no spots being covered or creases forming. Use a coat hanger if you’re dyeing a jacket.
2. Wipe the leather with an oil-soaked cloth
Soak the cloth or sponge you have decided to use with the oil of your choice and then proceed to wipe down the leather surface. Spread the oil out in a thin layer evenly to ensure that material is ready for the dye.
3. Use the abrasive on the leather
Complete nice and easy brushes with the abrasive. You don’t want to damage the leather obviously. You just want to kind of agitate it a bit and open it up. By doing that, you are opening up pockets that the dye can use to seep deeper into the leather.
4. Prepare the dye
Take the leather dyes out of their original containers and place them in little, shallow bowls if you have them. Keep them within reach at all times, so that you can apply them quickly.
The amount of dye you need to have will depend on what color you’re aiming for. More dye will be needed for a drastic move shift across the color spectrum.
It’s best to just have extra dye ready too.
5. Apply the dye to the material
Dip whatever clean cloth or applicator you’re using into the dye color and then transfer it to the leather surface. Work quickly in circular motions but carefully here. You must avoid having the dye dry up on you while you’re still working or the color may look off. Don't forget to wear gloves.
6. Let the leather dry
After the dye is applied, you must let the leather dry to ensure that the color will hold. You can speed up this process by using a hand dryer, but you can also just leave it be for a couple of days.
7. Seal up the leather
The leather sealer is needed for keeping the dye where it should be. Apply it carefully and avoid using too much. Just apply enough for the first coat on the leather and that should do the trick.
8. Allow the leather to rest some more
This is just a precautionary measure, but to make sure that no surprising issues arise, let the leather finish drying and give it some more time to recover before using it again. The sealer should not take long to work its magic, but just in case it does, leaving the material alone for a little longer can’t hurt.
At this point you should already be able to see how the leather paint has altered the look of the item you just worked on and are already marveling at the transformation. That’s the magic of the dyeing process and if you have some more leather items that could benefit from some restoration, you now know what to do.
