Can You Spray Paint Plastic to Look Like Metal
Yes, it can. All you need is the right spray paint, and you can give any plastic model a realistic metallic appearance. Good prep work is key to achieving the best possible finish. Ensure you sand lightly and prime the surface beforehand.
What Spray Paint Looks Like Metal?
If you want any item (including plastic) to look like bare metal, then you will need a metallic spray paint. Such paints usually contain tiny particles of metals such as aluminum, which help to reflect light and hence produce a shiny effect.
Depending on the brand, they can also be used to create a chipping or similar effect that highlights the layer underneath.
The paints typically look best indirect, natural light but still shine even in low light conditions. For the closest look to metal, choose a product that is highly reflective.
Like other type of finishes, metallics are available in various realistic colors. The most common ones are gold, brass, burnished brass, aged brass, and silver paint.
How to Give Plastic a Metallic Look
What You Need:
- Metallic spray paint.
- Clean cloth.
- Soapy solution.
- Paper towel.
- Gloves and mask.
Steps to follow:
Clean the Surface
Start by removing dirt and grease on the plastic item. You can use rubbing alcohol or mineral spirits.
After wiping the surface, rinse with a clean rag soaked in water, then allow it to air dry.
Most plastic surfaces are usually very smooth. Applying a primer directly on them might not produce the best adhesion.
So, it’s usually a good idea to rough up the surface a bit with fine-grit sandpaper or sanding block. This will give the surface some texture and ensure the primer sticks better.
If the plastic doesn’t look so smooth, you can skip this step.
Remove Sanding Dust
After sanding, dust the item to remove the sanding dust. You can use a large paintbrush or dry brush for this.
Next, wash with mild soap and water. Then air dry or dry with paper towels.
Once the surface is completely dry, mask any areas you don’t want to paint with masking tape. It’s also a good idea to cover the floor with newspaper or a drop cloth if you are spray painting indoors.
By now, you should have your gloves, mask, and glasses on.
Apply the primer
Apply one or two coats of primer and allow at least 15 minutes in-between coats. After the second coat, leave it to dry for at least an hour, depending on the product.
For the primer color, choose clear or black. Black primer might work better if you want the metallic color to look deeper, especially for display projects.
Make sure the primer is compatible with the plastic and paint, and ensure you follow the directions.
Apply the paint
Once the primer dries, you can now apply the metallic paint. Make sure to follow the instructions on the label.
Use 2 to 3 thin coat and allow each coat to completely dry before adding the next one.
After the last coat, let it dry for at least 24 hours before you use the item. You can add a clear coat, but this is completely optional.
How to Paint Plastic to Look Like Rusted Metal
To transform plastic to look like rusted metal, you will need a reactive metal paint. Reactive metal paints contain metal flakes, which are usually iron particles or other real metals that become rusty when activated.
The paints are typically applied with an activator or oxidization solution.
Follow the instructions on the label to apply the paint. Here are some tips:
- We recommend two coats of the base color followed by two coats of activator.
- The rust effect usually begins to show up after the activator has been applied. It may take up to an hour before it’s noticeable. The full impact is usually seen within 12 hours, depending on the product.
- Make sure the surface is clean and well-prepared before applying the base coat. Use an appropriate primer that ia compatible with the substrate, and remove all sanding dust beforehand.
- It’s always a good idea to test spray an inconspicuous area before moving on to the main project.
- The manner in which you apply the activator will determine whether the rust or other patina effect is even or irregular. Proper positioning of the material is also important.
- Besides plastics, most reactive metal paints will also work on glass, wood, walls, and other materials.
- After applying the paint, you can add a transparent top coat for additional protection.
How to Make Plastic Look Like Galvanized Metal
The process for painting plastic to look like galvanized metal is similar to the general steps described above.
The key is to use a metallic spray paint that has the closest look to galvanized steel and bonds to plastic. Also, you will need a plastic primer; it could be a black or clear primer.
The steps are summarized as follows:
- Start by cleaning the surface. Wipe with warm soapy water and rinse off with clean water. Then let it dry completely.
- For every smooth plastic surfaces, lightly sand to give it a dull texture.
- Next, apply a primer that is compatible with the item. A black primer will help create a deeper galvanized metal look. One or two coats of primer are enough. Allow to dry.
- Once the primer dries, you can apply the paint according to the manufacturer’s instructions. Allow it to fully cure before using the item.
How to Make Plastic Look Like Gold
To give plastic a gold look, apply 2-3 coats of your favorite metallic gold spray paint and let it dry. Then, finish off with a gliding wax like Antique Gold Rub n Buff.
The use of wax is completely optional, but it will add dimension to the product and produce the closest look to real gold.
For the best metallic gold spray paint, we highly recommend the Rust-Oleum American Accents Metallic Gold 2X Spray, which also includes a primer and can be used on both interior and exterior surfaces.
Besides spray paint, other ways you can transform plastic into gold look-alike include using gold paper decoupage, gold mineral paint, shiny contact paper, metallic wax finish, and genuine gold leaf.
How to Make Plastic Look Like Chrome
You can easily create a chrome effect on plastic by using a dedicated chrome spray paint. Ensure the paint is suitable for use on plastic and select a compatible primer.
The process is pretty similar to the ones above; the only real change is that you will be using a chrome spray paint. The steps are summarized as follows:
- First, prep the surface by removing dirt and oil.
- Next, apply a black primer that is compatible with the chrome paint. One or two coats of primer is usually enough.
