Patina is the name given to the discoloration that occurs on metals, wood, glass, or sculptures that have been exposed to the elements.
The patina will differ in color depending on the base metal as well as the substances to which it has been exposed.
Discoloration suggests age, and many people prefer patina colors to shiny new copper.
There are several ways to achieve a blue or blue-green patina on a surface before the material has aged.
What You Need
As we have already seen, this technique can be performed on multiple surfaces and materials.
Of course, depending on the material you use, the paints will change. However, for this technique you will need the following:
- Sealant to clog pores
- Black acrylic paint
- Blue paint
- Metallic colors: bronze, silver
How to Make a Patina?
Now that we are clear about what it is, what it is for and what you need to get started. Now, we explain how to make your patina:
1. Seal the pores of the sculpture
The first thing you should do to prevent your sculpture from absorbing paint quickly and losing it is to seal the pores.
The application of a sealant will depend on the material with which the piece is made of.
In the case of plaster or clay, you should apply more than one layer with a brush and let it dry.
In the case of wood, it is recommended to sand the surface previously.
2. Apply the base
Once the pores of the sculpture or material are completely sealed, you must apply a colored base.
If you are looking for a result typical of bronze or copper sculptures, this base should be made in black.
In the case of being used to paint a piece of furniture, it is recommended that the base be clear so as not to lose the style of the wood.
3. Apply the color for the patina
After applying a base to your workpiece, you should start to age it. You can use whatever color you prefer for the first coat.
In this case, the artist first uses blue and then applies the rest of the colors.
Use a dry brush with little color to achieve the desired effect and focus mainly on the indentations of the work to give it a more realistic appearance.
Of course, you can do this technique with any metallic color to give it one look or another.
4. Paint details
After the first color, you can apply other layers of metallics to give it a different look.
This layer should be done slowly and with care. Always with a dry brush and little load of paint.
Once finished, and optionally, you will only have to apply a varnish to protect your work. For this, you can use any acrylic or even spray varnish.
What is This Technique Used for?
This finishing technique is perfect to give a special touch to your works.
The patina will give your works a worn metal look, regardless of whether they are made of plaster, wood or any other material.
The patina is not used only for sculpture but it is suitable for multiple crafts, in addition to furniture or walls.
This technique clogs the pores on any surface, so less paint will be used on higher coats.
In addition, the patina effect helps to add volume to the pieces. The technique enhances their shadows and holes. Come on, they are all advantages!
Have a super-duper creation!
