What You'll Learn

Spray paint
To start, set up your work area outside or in a well-ventilated space. Cover the ground with newspaper or a dust sheet to protect the surface. Clean the pots with detergent and a soft cloth, and let them dry. If you are working with bare plastic, use a primer like Rust-Oleum Plastic Primer. If the pot has been painted before, use a fine-grade sandpaper to abrade the surface, then apply the primer.
Once the primer is dry, you can start spraying! Hold the can about 30cm from the surface of the pot and spray in a steady back-and-forth motion, slightly overlapping each stroke. Keep the can the same distance from the surface and keep it in motion for the best results. Apply several light coats a few minutes apart, and let the paint dry completely before adding your plant.
You can get creative with your designs by using different colours, trying out stencils, or even adding a textured finish. Spray paint is a versatile and easy way to transform your plastic plant pots and bring some colour to your garden.

Sealants
When it comes to sealants for outdoor painted plastic pots, there are a variety of options to choose from. Firstly, it is important to note that outdoor pots require sealing to protect the paint job from the elements, especially UV rays, and to prevent water from soaking through and damaging the paint.
One option for a sealant is a clear acrylic sealer with a matte finish. This type of sealant dries quickly and is invisible, making it a popular choice. It is important to ensure that all parts of the pot are covered, not just the painted areas, to prevent water from seeping through. Allow at least 48 hours for the sealant to cure fully before planting.
Another option is to use a clear synthetic coating such as Safecoat Poly EXT, which provides a tough, clear coat finish. This type of sealant can be used over water-based paint to protect your paint job. However, it is important to note that water sitting in the saucer can break down this coating over time. An alternative is to use a super-hardy sealant like AFM DynoSeal, which can be applied to the underside of the saucer to protect against water migration.
For a natural sealant option, tung oil, hemp oil, or walnut oil can be used. These oils provide a shiny finish and offer water-proofing for your outdoor pots. Shellac, a natural wax derived from beetles and mixed with alcohol, is another natural option that provides a shiny finish. It is typically used for indoor pots, but can also be used outdoors.
Additionally, Rustoleum sealant is a popular choice for outdoor painted plastic pots. It works on various surfaces, including plastic, and helps protect against the elements. It is important to allow the paint to dry completely before applying the sealant.

Acrylic paint
Painting outdoor plastic pots is a fun and easy DIY project that can be done with acrylic paint. Here is a step-by-step guide to achieving the best results:
Preparation:
Firstly, ensure your work area is covered with plastic or newspaper to protect it from paint. If using spray paint, work outdoors or in a well-ventilated area, wearing safety goggles and a mask. For brush painting, you can work indoors on a table for better arm support.
Cleaning and Sanding:
Start by cleaning the pot with soap and water or alcohol/nail varnish remover to ensure it is free from dirt and residue. Once dry, use sandpaper to sand the pot and remove the shiny outer surface. This creates a rougher surface for the paint to adhere to. Use fine-grit sandpaper to avoid leaving sandpaper lines. After sanding, brush away any loose debris or wash the pot again with warm, soapy water to ensure a clean surface.
Priming:
Primer is essential to ensure the longevity of the paint, especially for outdoor pots. Apply a primer paint or choose a paint that already includes a primer.
Painting:
Now you're ready to paint! If using a brush, load your brush with paint and then tap off the excess. Instead of a back-and-forth motion, try bouncing or dabbing the brush in an up-and-down motion. For brush painting, you may need multiple coats, allowing each layer to dry before applying the next.
Sealing:
Finally, seal your painted pot with a UV-resistant sealer to protect the paint and ensure its longevity. Allow the pot to dry overnight before using it.
Design Ideas:
The design options are endless! You can opt for a single colour or get creative with a unique design. Try stencilling, vinyl appliques, or even creating a textured effect by mixing paint with a secret ingredient.
Remember, when choosing paint, opt for those made specifically for plastic to ensure the paint adheres well and doesn't crack or flake over time. Enjoy bringing new life to your outdoor plastic pots!

Embellishments
Embellishing your plastic pots with paint is a fun and easy DIY project that can transform your outdoor space. Here are some creative ideas to add unique and stylish touches to your painted plastic pots:
Mould Castings and Air-Dry Clay:
Mould castings are a unique way to embellish your painted plastic pots. You can use IOD silicone moulds and air-dry clay to create intricate designs. The softness of the air-dry clay allows it to easily conform to the curved surfaces of your pots. Simply fill the moulds with clay, smooth the surface with a paintbrush handle, and let it dry. Then, carefully remove the casting from the mould and glue it onto the pot using a strong adhesive like Tite-Bond Quick & Thick glue.
Permanent Markers:
Permanent markers, such as Sharpies or POSCA paint markers, are a simple yet effective way to add embellishments to your painted pots. You can create various designs, from geometric shapes like triangles, circles, and squares to more intricate patterns like mud cloth designs. These markers work well on painted plastic surfaces and can add a unique touch to your pots.
Textured Paint:
Adding texture to your paint can create a unique and visually appealing finish. You can mix your paint with a secret ingredient, such as sand or another granular substance, to create a textured effect. This technique can give your pots a natural, rustic, or distressed look, depending on the colour and type of paint used.
Sealant:
While not necessarily an embellishment, using a sealant is an important step to protect your painted pots from the elements. A sealant like Rustoleum will not only protect your paint job but can also add a subtle sheen, enhancing the overall appearance of your pot. It is recommended to wait until your paint and design are completely dry before applying a layer of sealant.
Filler Plants:
Consider adding filler plants or flowers to your painted pots to create a vibrant and lush display. Combine different colours and varieties of plants to complement the colours and designs of your pots. This will not only make your pots more visually appealing but will also create a beautiful and thriving garden decoration.
Remember, when embellishing your painted plastic pots, the possibilities are endless. You can mix and match different techniques, colours, and designs to create unique and personalised creations that reflect your style and inspire your green thumb!

Stencils
First, you will need to select your stencil design. You can purchase stencils from craft stores or create your own. If you are creating your own, you can cut your design out of outdoor-quality vinyl. Next, you will need to clean the surface of your pot to ensure that the paint adheres properly. If your pot is glazed, you may want to lightly sand the surface. Then, apply a thin coat of paint and let it dry.
Once your base coat is dry, it's time to start stencilling! Apply stencil glue to the back of your stencil and press it onto the pot. You may need to wait 10 minutes for the glue to dry. Then, use a paint marker or a small paintbrush to fill in the stencil. Be careful not to let the paint bleed under the stencil, as this will affect the crispness of your design. Once you are done painting, remove the stencil and let the paint dry before moving on to the next section.
Finally, you will need to seal your pot to protect your design. You can use a clay pot sealer, a regular acrylic sealer, or an outdoor varnish. Apply two to three coats, allowing each coat to dry before applying the next.
