What You'll Learn
Choosing the right paint for plastic
Painting plastic can be challenging due to its non-porous, smooth, and chemically unique surface that does not promote good paint adhesion. However, with the right paint and preparation, you can achieve success in painting plastic surfaces. Here are some tips for choosing the right paint to ensure a durable and attractive finish:
Choose Paint Formulated for Plastic:
Select a paint specifically designed for use on plastic surfaces. These paints have special bonding agents that help them adhere to smooth plastic surfaces. Look for spray paints formulated for plastic if you prefer spray painting.
Opt for Acrylic or Enamel Paint:
If you prefer brush painting, opt for acrylic or enamel paint. These types of paint are known to work well on plastic when used with a suitable primer. Acrylic paint, in particular, is a good choice for both brush and spray applications.
Avoid Latex Paints:
Latex paints are not ideal for plastic as they don't bond well and may cause peeling or cracking over time. Instead, choose primers and paints made specifically for plastic surfaces to ensure better adhesion and durability.
Consider the Plastic Type:
Different types of plastic can accept paint differently. Plastics labeled 3, 6, or 7 tend to be more receptive to paint than others. Check the recycling label on the plastic milk crate to determine the type of plastic and choose your paint accordingly.
Prepare the Surface:
Before painting, ensure the plastic surface is clean and dry. Lightly sand the surface with fine-grit sandpaper (180-300 grit) using circular motions to create a slightly rough texture that will help the paint grip better. Remove any sanding dust with a damp cloth and let the surface dry completely before painting.
Apply Multiple Thin Coats:
Regardless of the paint type you choose, always apply multiple thin coats of paint, allowing each coat to dry completely before applying the next one. This technique will help you achieve a smoother finish and prevent drips, runs, and sags.

Preparing the crate for painting
Clean the Crate
Start by giving your milk crate a thorough cleaning. Use mild soap and water, especially if the crate has been kept outdoors. This step is important as it removes any dirt, dust, or grime that may prevent the paint from adhering properly. Ensure you wash all surfaces of the crate, paying extra attention to any nooks and crannies. Once you're done, dry the crate thoroughly.
Scuff the Surface
Once the crate is clean and dry, it's time to scuff up its surface. Use fine-grit sandpaper to gently roughen the surface of the plastic. This process helps create a "tooth" for the paint to bite into, improving its adhesion. Be sure to scuff evenly and thoroughly, covering all the areas you plan to paint.
Choose a Primer
Select a primer designed specifically for use on plastic. This step is essential, as it will ensure the paint adheres properly. Look for primers labelled as plastic-appropriate or plastic spray primer. You can find these at most hardware stores or craft supply stores.
Prepare Your Work Area
Set up your work area outdoors on a non-windy day or in a well-ventilated room. Cover the surrounding area with newspaper or cardboard to protect it from paint overspray. Put on a dust mask to avoid inhaling any paint fumes. It's also a good idea to wear old clothes or an apron to protect your clothing from paint splatters.
Apply the Primer
Follow the instructions on the primer can for proper application. Typically, you'll hold the can about 12 to 18 inches away from the crate and use smooth, parallel, and overlapping arm motions to ensure even coverage. Be sure to cover all the areas you plan to paint. Allow the primer to dry completely according to the manufacturer's instructions before moving on to painting.
By following these steps, you'll have a milk crate with a properly prepared surface, ready for a fresh coat of paint!

Painting techniques for plastic
Painting plastic milk crates is a great way to upcycle them and use them for storage or decor. It is possible to spray paint plastic and get it to stick well, but it requires the right amount of preparation.
Firstly, set up your workspace. Choose a well-ventilated area, preferably outside, and cover your work surface with newspaper, a cheap tablecloth, or cardboard. If there are any parts of the plastic milk crate that you do not wish to paint, cover them with painter's tape. Clean the crate with mild dish soap and warm water to remove any surface dirt. Use a soft cloth or sponge for this step, and rinse the crate with fresh water afterward, then dry it off.
Next, lightly buff the surface with 220 to 300-grit sandpaper, using a light touch and a circular motion to avoid scratches. Wipe the surface with a tack cloth after sanding to remove any dust. You can then use a primer designed for spray painting plastic, which will help you achieve a perfect finish.
When you are ready to paint, hold the can between 8 and 12 inches away from the plastic, with the can tilted at about a 45-degree angle. Spray lightly across the surface, moving the can forward instead of backward to prevent overspray. Do not aim for total color coverage as this will lead to drips. Let the plastic dry for at least two hours in a warm, dry environment, and then apply a second coat. Spray lightly again, keeping the can tilted at an angle, and mist the surface. After letting the crate dry for a few hours, give the surface a final coat of paint.

Creating a two-tone finish
Painting plastic milk crates can be an easy and budget-friendly way to create a stylish storage solution. To achieve a two-tone finish, follow these steps:
First, ensure that your milk crates are made of plastic. While milk paint is a versatile option for various surfaces, it is best to use a spray paint formulated for plastic to achieve a long-lasting finish. Prepare your work area by setting up cardboard or newspaper in a well-ventilated space, preferably outdoors, on a non-windy day. Protect yourself by wearing a dust mask, goggles, and gloves.
Next, clean the plastic milk crates with mild soap and water to remove any dirt or residue. Once the crates are dry, use fine or very fine sandpaper to gently scuff the surface. This step will help the primer adhere better to the plastic. If there are any labels or glue residue on the crates, use a product like goo gone or WD40 to remove them.
Now, it's time to prime the crates. Apply a plastic-appropriate primer evenly to the sanded surface of the crates. This step will ensure that your paint adheres properly and doesn't peel off easily. Allow the primer to dry completely according to the manufacturer's instructions.
Once the primer is dry, you can start creating your two-tone finish. Choose two complementary colors of spray paint that are suitable for plastic. Apply the first color as your base coat, using thin and even coats. Allow this base color to dry for at least a day.
After the base color is dry, it's time to add the second tone. Use painter's tape to create the desired pattern, such as stripes, chevrons, or zebra print. Apply the tape over the base color, creating the design you want for your second color. Press the tape down firmly to prevent paint from seeping underneath.
Now, spray paint the second color onto the exposed areas of the crate, using thin and even coats. Once you're happy with the coverage, carefully remove the painter's tape while the paint is still wet. Allow the paint to dry completely.
Finally, you can add a protective topcoat to your painted milk crates. A clear spray polyurethane can help prevent scratches and provide a long-lasting finish. However, if you've used metallic paint, avoid using polyurethane as it will dull the shine.
With these steps, you can create a beautiful and unique two-tone finish on your plastic milk crates, adding a personal touch to your storage solutions.

Adding extra decorations
Painting plastic milk crates is a great way to add a stylish and personalised touch to your home or office. Once you've chosen your paint colours and successfully painted your crates, you can take your project to the next level with some extra decorations.
One option is to wrap colourful cotton rope around the crate, securing it with dots of glue. You can create a striped effect by switching out the colour of the rope halfway through. This technique adds texture and interest to your milk crate, making it a unique feature in your space.
If you're feeling extra creative, try combining your painted milk crates with other materials such as fabric or wood. For example, if you're handy with a sewing machine, you can create a fabric outer for your plastic crate, adding contrasting pockets to store smaller items. This gives your storage solution a soft, cosy feel while also showcasing your sewing skills.
For a more rustic or retro look, consider combining your painted milk crates with wooden elements. You can use milk crates as shelves within a wooden dresser, giving it a unique and updated look. This is a great way to upcycle an old dresser and give it a new lease of life.
Don't be afraid to experiment with different decorative elements and techniques. Milk crates are versatile and durable, making them the perfect blank canvas for your creativity. Whether you're going for a sleek and modern look or something more eclectic, adding extra decorations to your painted milk crates can truly make them one-of-a-kind.
