What You'll Learn
Choosing the right paint
Type of Paint
The most suitable types of paint for plastic garden tubs are epoxy paint and acrylic paint. Epoxy paint is a popular choice due to its durability, chemical resistance, and abrasion resistance. It is a two-part system that requires mixing before use, and it is important to carefully follow the manufacturer's instructions for proper application and curing time. Epoxy paint provides a long-lasting finish.
Acrylic paint is another viable option. It is easy to apply, dries quickly, and offers a range of colours and finishes to choose from. However, it may not be as durable as epoxy paint and may require touch-ups over time. If you prioritise ease of application and a quick drying time, acrylic paint could be a good choice.
Surface Preparation
Before painting, it is essential to properly prepare the surface of your plastic garden tub. This may involve cleaning, sanding, and applying a primer. Ensure that the surface is free from dirt, grease, or any other contaminants that may prevent the paint from adhering properly. Sanding the surface creates a rough texture, enhancing the paint's grip and adhesion. You can use sandpaper or a sanding block for this step, but avoid power sanders as they can be difficult to control.
Paint Application
Consider the application method that works best for you. Spray paint is convenient and easy to apply, but it may not be as durable as other options and may require touch-ups. Brush painting provides more control but leaves more room for error. Using a compressor and sprayer can give you a smooth finish, but ensure you follow the manufacturer's instructions for the best results.
Environmental Factors
If your plastic garden tub is for outdoor use, consider the environmental factors it will be exposed to. Choose a paint that is suitable for outdoor conditions, such as weather resistance and UV protection. This will help maintain the appearance and integrity of the paint over time.
Colour and Finish
Lastly, consider the colour and finish you desire for your plastic garden tub. Epoxy and acrylic paints typically offer a variety of colour options, allowing you to match your garden's aesthetic or create a unique colour scheme. Think about the finish you want to achieve, whether it's a matte, glossy, or textured finish, as this will also influence the overall look and feel of your project.

Preparing the surface
Firstly, it is essential to thoroughly clean the tub to remove any dirt, soap residue, or other contaminants. Dunk the tub in a bucket or sink filled with warm soapy water, and ensure that you wipe down both the inside and outside of the tub. This step is crucial as any remaining dirt or grease will prevent the paint from adhering properly. Once the tub is clean, make sure it is completely dry before moving on to the next step.
Next, you will need to sand the tub to create a rough surface that the paint can grip onto. Use 120-grit sandpaper or the sandpaper provided in your refinishing kit if you have one. Be sure to sand the entire surface evenly, ensuring that you don't miss any spots. This step will help the paint adhere better and result in a smoother finish. After sanding, wipe down the tub to remove any remaining dust or debris.
To further prepare the surface, you may need to apply a chemical stripper or plastic epoxy remover, especially if the tub has a shiny finish. Be sure to wear protective gear, including respirators, goggles, and gloves, when working with these products. Follow the manufacturer's instructions for application and drying time. Once the stripper has done its job, wipe down the tub again to remove any traces of the product and the stripped material.
Finally, apply a primer to the surface of the tub. The primer will provide a base for the paint to stick to and ensure better adhesion. Spray primers are a convenient option, but one light coat is usually sufficient. Allow the primer to dry adequately before moving on to the painting stage.
By following these steps, you will effectively prepare the surface of your plastic garden tub for painting, ensuring a durable and long-lasting finish.

Sanding the tub
First, ensure that the tub is completely dry. If you have recently cleaned the tub with soap and water, allow ample time for it to dry before beginning the sanding process.
Next, gather the necessary materials. Your refinishing kit should come with the appropriate sandpaper for creating a rough surface on the tub. If you don't have a refinishing kit, 120-grit sandpaper or 180-grit sandpaper will work well.
Now, it's time to start sanding! Use the sandpaper to roughen the surface of the tub. You don't need to sand aggressively or for a long period; simply give the tub a good once-over with the sandpaper. Be sure to cover the entire surface of the tub evenly, without missing any spots. This step will help the paint adhere better and create a more durable finish.
After sanding, use a brush or cloth to wipe down the tub and remove any loose debris or residue from the sanding process. This will ensure that the surface is clean and ready for the next step, which is typically applying a primer to further enhance paint adhesion.
By properly sanding your plastic garden tub, you will create a better surface for the paint to grip onto, resulting in a more durable and long-lasting paint job.

Applying the primer
Prepare the Surface:
Before applying the primer, it is essential to prepare the surface of the plastic garden tub. This involves cleaning the tub thoroughly to remove any dirt, grease, or soap residue. Use a bucket of warm soapy water or a suitable cleaner to ensure the surface is completely free of contaminants. Make sure to dry the tub completely before proceeding to the next step.
Sand the Surface:
Once the tub is clean and dry, it's time to sand the surface. Sanding the tub will create a slightly roughened surface, providing a good grip for the paint to stick to. Use 120-grit or 180-grit sandpaper, and sand the entire surface evenly. Be careful not to miss any spots. This step will help ensure that the primer and paint adhere properly.
Protect the Surrounding Area:
Before priming, it's important to protect the surrounding area to avoid any unwanted paint splatters. Use painter's tape to tape off the edges of the tub, the drain, and any fittings or fixtures. This will ensure that you get clean, precise lines and protect the areas you don't want to paint.
Choose the Right Primer:
Select a primer that is specifically designed for plastic surfaces. It should be compatible with the type of paint you plan to use (e.g., epoxy or acrylic paint). Follow the manufacturer's instructions for the recommended primer to use with their paint.
Apply the Primer:
Now you're ready to apply the primer. Primers often come in spray-can formats, which are easy to use. Follow the instructions on the primer's packaging for the proper application method. Typically, you'll need to apply only one light coat of primer to the entire surface of the tub. Ensure you have adequate ventilation during the application and allow the primer to dry completely before moving on to the next step.
By following these steps for applying the primer, you'll create a strong foundation for your paint job and ensure that your new coat of paint adheres well and lasts a long time. Remember to refer to the manufacturer's instructions for any specific recommendations or requirements for their products.

Sealing the paint
It is important to note that not all paints require a sealant. For example, epoxy paint is a popular choice for painting plastic tubs because of its durability and resistance to chemicals and abrasions. Epoxy paint may not require a sealant as it is already designed to be long-lasting. However, if you choose a different type of paint, such as acrylic or spray paint, you may need to seal it to ensure its longevity.
When choosing a sealant, consider factors such as durability and ease of application. You may want to opt for a sealant that is specifically designed for plastic surfaces. This will ensure that the sealant adheres well to the surface and provides a long-lasting finish. Properly preparing the surface before sealing is also crucial. Make sure the surface is clean and free of any dirt, grease, or debris. You may need to sand the surface to create a rough texture, which will help the sealant grip onto the tub.
Additionally, you may want to use a bonding agent before applying the sealant. A bonding agent will help the sealant adhere better to the surface. Follow the instructions on the product and allow the bonding agent to dry adequately before proceeding. By taking the time to properly prepare and seal your plastic garden tub, you can ensure a beautiful and long-lasting finish.
