Cleaning the surface of the blue plastic barrel
To paint a blue plastic barrel, it is important to first clean the surface thoroughly. This is because paint adheres better to a clean surface, and the barrel will have a more aesthetic appearance. Here is a step-by-step guide to cleaning the surface of a blue plastic barrel:
Inspect the Barrel:
Before beginning the cleaning process, it is important to inspect the barrel for any signs of damage, wear and tear, or corrosion. Look out for cracks, leaks, or other visible damage. If the barrel is damaged, it may not be suitable for painting or for certain types of storage.
Choose the Right Cleaning Agents:
The choice of cleaning agents depends on what was previously stored in the barrel. If it was used to store chemicals, you will need to use a water-based cleaning solvent or alkaline solution to neutralise any acidic substances. Avoid using harsh chemicals as these can damage the plastic. Always read the labels on your cleaning solutions to ensure they are safe for use on plastic.
Gather the Right Tools:
If you are cleaning chemical residues, you will need specialised tools such as a high-pressure washer, soft-bristled brushes for delicate areas, stiff-bristled brushes for tougher areas, a bucket, a hose, and protective gear such as a respirator. If the barrel has not been used for chemical storage, you may only need a bucket, soap or rubbing alcohol, and some rags or sponges.
Clean the Barrel:
If the barrel has been stored for a long time or used for transporting goods, it will likely need a thorough cleaning to remove grime. Start by rinsing the barrel with clean water. Then, use soapy water or a mild cleaning solution and a soft cloth or sponge to wipe down the barrel. For tougher stains or chemical residues, you may need to use a high-pressure washer or scrub brushes. Rinse the barrel again to remove any residual cleaning agents, and then dry it completely with a clean cloth or leave it to air dry in the sun.
Prepare the Surface:
Once the barrel is clean and dry, you can prepare the surface for painting. Use fine-grade sandpaper to lightly "rough up" the surface of the barrel. This step will help the paint adhere better. Vacuum the barrel's surface to remove any dust, and then rinse and dry it again.
Now that the surface of your blue plastic barrel is clean and prepared, you can start the painting process!

Choosing the right primer
When it comes to choosing the right primer for your project, there are several factors to consider. Firstly, identify the type of surface you are working with. Different primers are suitable for different surfaces, such as wood, metal, plastic, drywall, or masonry. For example, if you are priming wood, an oil-based primer or a latex primer would be suitable. If you are priming metal, a general-purpose primer like Coo-Var Red Oxide Metal primer is a good choice as it has anti-corrosive properties.
Secondly, consider the condition of the surface. If you are working with a previously painted or coated surface, it is important to identify the type of coating used (acrylic vs. alkyd) to select the appropriate primer. A simple way to test this is to rub a cotton ball dipped in 70% isopropyl alcohol on the surface. If the paint comes off, it is acrylic-based, and if it doesn't, it is alkyd-based. If the surface is in good condition and has already been sealed, you may not need to apply a primer at all.
Thirdly, determine the desired finish and longevity of your project. The primer you choose will impact the final finish, performance, and overall durability of your paint job. If you are looking for a specific finish, such as high gloss or satin, choose a primer that is designed for that finish. Additionally, consider the level of stain resistance, mildew resistance, and adhesion you require. For example, if you are painting in a high-humidity environment, choose a primer that contains a biocide to protect against fungal degradation.
Lastly, refer to the manufacturer's instructions for specific recommendations or restrictions regarding the primer. Some primers may be specifically designed for certain surfaces or conditions, so it is important to follow the manufacturer's guidelines for optimal results. By considering these factors and selecting the right primer, you can achieve a professional-looking finish and ensure the longevity of your paint job.

Selecting the paint type and colour
Spray paint, such as Krylon Fusion or Rust-Oleum, offers a wide range of colours and finishes, including satin and gloss. It provides good coverage and adhesion to plastic, but it can be more expensive and may have strong fumes. Brush paint allows for more detailed and decorative artwork, as seen in the Tiki Guys design, but it may require a primer for better adhesion. Roller paint, such as latex house paint, is a cheaper option, but it may not adhere as well to the smooth plastic surface.
The colour choice for your blue plastic barrels depends on your personal preference and the intended purpose. You can choose a colour that matches your house, like Melissa's white barrels or Erik's choice to match the house's subtle contour, or you can select a colour that makes a statement or blends into the surroundings. Consider the functionality of the colour as well. For example, blue barrels are UV-resistant and won't grow algae, while white barrels may face that issue over time.
Additionally, you can get creative with your paint designs. For instance, you can use stencils, such as branches, to create a camouflage effect, or you can use sponges and paintbrushes to add dots and details, as seen in the Tiki Guys design. There are also decorative painting techniques, such as the decorative approach credited to Studio Ghibli & Natsume Yuujinchou.
Remember, the paint type and colour you choose will impact the overall aesthetic and functionality of your painted blue plastic barrels. Take into account the preparation and priming steps for each paint type to ensure a smooth and long-lasting finish.

Applying the paint
When you are ready to paint, ensure you are in a well-ventilated area. If painting outdoors, make sure it is not too windy to avoid dust and debris from sticking to the paint. You may also want to place a drop sheet underneath the barrel to protect the surrounding area.
Before applying the paint, ensure the barrel is clean and dry. If there is any dust remaining on the surface, it may affect the finish. You can use a vacuum to remove any lingering dust particles.
It is recommended to use a flexible paint designed for use on plastic, such as Krylon® Fusion Spray Paint for Plastic® or Rust-Oleum*. These paints typically come in spray form, but you can also use a roller or brush. If you are using spray paint, ensure you follow the instructions on the can, including the recommended distance to hold the can from the surface and the proper technique for application.
If you want to get creative, you can use stencils or sponges to create designs. You can also use different colours to match your house or create a unique look. Some people have painted Tiki people on their barrels, while others have used branches as stencils to create a camouflage effect.
Most paints will require a drying period of at least 48 hours. During this time, avoid touching or moving the barrel to prevent any smudging or paint transfer. After the paint has dried, you may need to apply a top coat or sealant to protect the paint job, especially if the barrel will be exposed to the elements.

Sealing the paint
Prepare the Barrel Surface:
Start by cleaning the barrel's surface with a mixture of vinegar and water. This will remove any dirt, grime, or transportation residue. You can also use soapy water or rubbing alcohol for a deeper clean. Ensure you rinse the barrel with clean water and dry it thoroughly.
Prime the Barrel:
Apply a coat of outdoor primer specifically designed for plastic surfaces, such as Krylon Fusion or Rust-Oleum plastic spray primer. Two cans of primer are typically needed to coat a standard barrel adequately. If the primer leaves a glossy finish, gently buff it with fine-grade sandpaper to create a smoother base for the paint.
Paint Application:
Follow the manufacturer's instructions for applying paint to ensure an even coat. Depending on the desired finish, you may need to apply two or more coats of paint. Acrylic paints are a popular choice for painting plastic barrels and can be applied with brushes or spray paint. Allow sufficient drying time between coats, following the recommendations on the paint can.
Seal the Paint:
Once the paint is completely dry, it's time to seal it. You can use a clear sealant spray, such as Krylon Fusion UV protectant spray or Rust-Oleum clear crystal. These sealants will protect the paint from weathering and fading due to UV exposure. Alternatively, you can use a lacquer or an automotive clear spray for a durable finish. Ensure you follow the instructions on the sealant can for proper application techniques and drying times.
Drying and Curing:
After applying the sealant, allow ample time for the barrel to dry and cure. This process may take several hours or even days, depending on the products used and environmental conditions. Refer to the manufacturer's guidelines for specific drying and curing times.
By following these steps, you will effectively seal the paint on your blue plastic barrel, resulting in a durable and aesthetically pleasing finish.
