Use a roller for open surfaces and a paintbrush for hard-to-reach areas
Painting a plastic storage tub requires the right supplies and preparation. You'll need to wear safety gear, such as a face mask and gloves, to protect yourself from the paint. It is also important to cover the floor and any taps or plug holes with newspaper or a drop cloth to avoid paint drips and spills.
Before painting, ensure the tub is thoroughly cleaned and dried. Use a bathroom cleaner and an abrasive sponge to get the surface as clean as possible, and then sand the tub with fine sandpaper. This will give the paint something to grip onto.
When you're ready to paint, use a roller for the open, smooth surfaces of the tub. A small roller will help you achieve an even and streak-free finish. For hard-to-reach areas, such as corners, grout lines, and tight spaces, switch to a paintbrush. You may need to apply extra pressure and work the brush into these areas, but a brush will give you more precision and control.
Foam rollers and paintbrushes are good options for these types of projects, but they may require multiple replacements as the paint can disintegrate the foam and bristles. It is also important to note that epoxy paint can ruin brushes, so consider using a foam roller for corners to avoid brush strokes.
Depending on the colour you are painting and the coverage you desire, you may need to apply multiple coats of paint. Allow adequate drying time between coats, following the instructions on your paint, and consider finishing with a layer of acrylic top coat to seal in the paint and add extra shine.

Sand the tub to give the paint something to grip onto
Sanding the plastic storage tub is an essential step in preparing the surface for painting. Most plastic surfaces are glossy and smooth, and sanding creates a rougher, matte finish to which paint can better adhere. By giving the tub's surface a light sanding, you are providing a grip for the paint, helping it stick to the plastic and ensuring the paint job is long-lasting.
It is recommended to use fine-grit sandpaper for sanding plastic. This will create a slightly rougher surface without leaving visible sanding marks. Start with a lower grit and work your way up to a finer grit. You can also use a sanding sponge or foam block, which will give you better control and prevent deep scratches. Move the sandpaper or sponge in erratic, circular patterns to avoid harsh lines and scratches.
Before sanding, ensure the tub is thoroughly cleaned and dried. You can use a scrub brush or sponge to remove any dirt, mildew, or flaking paint. A final wipe with mineral spirits or isopropyl alcohol will remove any remaining dust or grease. It is important to work in a well-ventilated area when using chemicals like mineral spirits.
After sanding, wipe down the tub with a damp cloth to remove any dust or debris. Allow the tub to dry completely before proceeding to the next step, which is applying a primer. The primer will further smooth out the surface and improve paint adhesion. Once the primer is dry, you can start spray painting or rolling on your chosen paint colour.
Remember to follow the paint manufacturer's instructions for drying time and apply multiple light coats rather than a single thick coat to avoid drips and ensure an even finish. Allow adequate drying time between coats, and finish with a clear top coat if desired for added protection and shine.

Use a bonding agent to smooth the surface and help paint adhere
Painting a plastic storage tub can be a great way to give it a new look or cover up old stains. To ensure the paint job is long-lasting, using a bonding agent is essential. A bonding agent will smooth out the surface of the plastic tub and help the paint adhere to it.
A bonding primer is a special type of primer that adheres to hard-to-cover dense or porous surfaces. Its chemical composition allows it to adhere to surfaces better than regular primers. It creates a thick film over the surface, preventing peeling, cracking, and fading. When choosing a bonding primer, opt for one that is specifically designed for use on plastic surfaces, such as INSL-X® STIX® Waterborne Bonding Primer. This primer will create a durable surface for the paint to adhere to and provide a professional finish.
Before applying the bonding primer, ensure the plastic tub is thoroughly cleaned and dried. Use a mild detergent or your usual bathroom cleaner and an abrasive sponge to get the surface as clean as possible. You may also want to lightly sand the tub with fine sandpaper to create a rough surface for the primer to grip onto.
To apply the bonding primer, follow the manufacturer's instructions. Typically, you will only need to apply one coat of the primer, but this may vary depending on the condition of your tub and the number of coats of paint you plan to apply. Use a brush, roller, or spray bottle to apply the primer, ensuring even coverage across the entire surface. Allow the primer to dry completely before proceeding to the next step.
Once the bonding primer is dry, you can begin painting your plastic storage tub. Choose a paint that is suitable for plastic surfaces, such as acrylic enamel. Apply the paint in thin, even layers, allowing adequate drying time between coats as per the manufacturer's instructions. Finally, seal your paint with a layer of clear acrylic topcoat to add extra shine and protection.

Apply two coats of colour and one coat of clear acrylic
Painting a plastic storage tub can be a great way to give it a new look or cover up old stains. When it comes to applying the paint, it's recommended to apply two coats of colour and one coat of clear acrylic for the best results.
First, ensure you have the correct safety gear, including a face mask and gloves, to protect yourself from the paint. It's also a good idea to cover the floor and any taps or plug holes with newspaper or masking tape to avoid getting paint on them.
Now, you can start by giving your storage tub a thorough clean using a bathroom cleaner and an abrasive sponge. This will help create a smooth surface for the paint to adhere to. Once it's clean, sand the tub with fine sandpaper to give the paint something to grip onto. Wipe away any grit and ensure the surface is completely dry.
Next, you can start applying the paint. Use a small roller instead of a brush to achieve an even and streak-free finish. Apply the first coat of your chosen colour evenly to the entire tub and allow it to dry according to the paint's instructions. Once it's dry, apply the second coat of colour.
After the second coat of colour has dried, it's time to apply the clear acrylic coat. This will seal in the paint, add extra shine, and ensure a bold colour. Again, follow the instructions on your chosen paint for drying times. However, it's generally a good idea to let the final coat dry for about an hour before moving or touching the tub too much. Try to avoid placing items inside the tub for at least 24 hours to give the paint enough time to properly bond to the plastic surface.

You can purchase a bonding agent from hardware stores or online. Additionally, ensure you have the necessary safety gear, including a face mask and gloves, to protect yourself during the painting process.
Once you have your supplies, start by giving the tub a deep clean. Use a bathroom cleaner and an abrasive sponge to thoroughly clean the surface. After cleaning, sand the tub with fine sandpaper. This step will create a rougher surface, providing a better grip for the paint. Remember to wipe down the tub after sanding to remove any grit and ensure it's completely dry before you start painting.
When you're ready to paint, apply the paint evenly to the entire tub. Depending on the paint you choose, you may need to apply multiple coats to achieve the desired coverage and colour. Be sure to follow the paint manufacturer's instructions for drying time between coats. After you've achieved the desired coverage, allow the paint to dry completely. Finally, apply a layer of clear acrylic coat to seal and protect the paint job. This top coat will also add extra shine to your tub. Again, allow adequate drying time for the acrylic coat, typically about an hour, before moving the tub.
Using outdoor paint and following these steps will help you successfully paint your plastic storage tub, ensuring it can withstand exposure to the elements while looking great!
