Clean the tub thoroughly
Before painting an ABS plastic tub, it is crucial to clean it thoroughly. This step ensures that the paint adheres smoothly and evenly to the surface, resulting in a professional and long-lasting finish. Here is a detailed guide to help you through the process:
Firstly, ensure you have the right cleaning products. While there are numerous bathtub cleaning products available on the market, you can also opt for inexpensive, homemade solutions. A simple and effective combination is vinegar and dish soap. Vinegar is an excellent disinfectant and cleaner, while dish soap helps to cut through soap scum and residue. Alternatively, you can use a commercial all-purpose cleaner, which is typically safe for plastic tub surrounds. Just be sure to check the label to ensure it is suitable for ABS plastic and non-abrasive. Avoid using abrasive cleaning products or solvents, such as scouring powders, mineral spirits, acetone, or turpentine, as these can damage the plastic surface.
Now that you have your cleaning product, it's time to apply it to the tub. If you're using a spray bottle, fill it with your chosen solution and spray it liberally onto the surface of the tub. Allow the solution to sit for a few minutes to activate and break down any dirt, grime, or stains. For tougher stains, you may want to use a cleaning eraser, which can be moistened with water and scrubbed over the surface for extra cleaning power.
The next step is to scrub the tub. Use a soft cloth, such as microfiber or terry cloth, or a soft sponge, and gently scrub the surface. These materials are gentle on the plastic, ensuring no scratches are formed. Be sure to reach into all corners and crevices for a thorough clean. If you're using a cloth, it's a good idea to dip it in warm water to enhance the cleaning process.
Finally, rinse the tub with clean water to remove any remaining residue from the cleaning solution. You can use a damp cleaning cloth or sponge to wipe down the tub, ensuring no streaks or water spots are left behind. It is important to ensure the tub is completely dry before proceeding with the painting process.
By following these steps, you will have a clean and prepared ABS plastic tub, ready for a new coat of paint.

Sand the tub
Sanding the tub is an important step in the process of painting an ABS plastic tub. It helps create a surface that the paint can properly adhere to, resulting in a more durable and long-lasting finish. Here is a step-by-step guide to sanding your plastic tub:
Start by ensuring your tub is clean and dry. Use an abrasive sponge and your usual bathroom cleaner to thoroughly scrub the tub, removing any mildew, soap scum, or built-up deposits. It is crucial to have a clean surface before sanding to achieve the best results.
Once the tub is clean and dry, you can begin the sanding process. Fine-grit sandpaper, typically around 220-grit, is recommended for sanding plastic surfaces. Sand the entire tub evenly, creating a rough texture that will allow the paint to grip. If you have a previously painted tub, you may need to sand more thoroughly to remove the old paint and expose the underlying material. However, be cautious not to over-sand, as it can create a problem by making the surface too smooth or uneven.
After sanding, wipe down the tub to remove any traces of grit or dust. Ensure the tub is completely dry before proceeding to the next step, which is applying a bonding agent or primer. This step is crucial in ensuring proper paint adhesion and a smooth finish.
It is important to wear the appropriate safety gear during the sanding process, including a face mask and gloves, to protect yourself from inhaling dust or coming into contact with harsh chemicals. Additionally, covering the surrounding area with a drop cloth or newspaper will help catch any sanded-off material and protect the floor from paint drips during the subsequent painting process.
By following these steps and taking the necessary precautions, you will effectively sand your ABS plastic tub, creating a suitable surface for painting and achieving a professional and long-lasting finish.

Use a bonding agent
Painting an ABS plastic tub requires the right tools and safety gear. Before you begin, ensure you have the correct safety gear, such as a face mask and gloves, to protect your skin and respiratory system. Lay down something to cover your floor, such as newspaper, in case of paint drips. Cover your taps and plug holes with masking tape to keep them free of paint.
Give your tub a deep clean using your usual bathroom cleaner and an abrasive sponge to get the surface as clean as possible. You should then sand the tub with fine sandpaper. This will give your paint something to grip onto. Wipe out your tub to remove any traces of grit, and ensure it is completely dry.
Now, you can apply a bonding agent to the tub's surface. This will help smooth out the surface and allow your paint to adhere and last longer. Your bathtub refinishing kit should come with a bonding agent. Apply this using a roller for open surfaces and a paintbrush for hard-to-reach areas. Once the bonding agent is dry, you can proceed with the paint primer.
After the primer, you are finally ready to paint your tub. Apply your paint of choice to the entire tub in one even layer. Allow adequate drying time according to your paint's instructions, then apply a second layer if necessary. Finish with a layer of acrylic topcoat to seal in your paint and add extra shine.

Apply primer
Before applying primer to your ABS plastic tub, it is important to prepare the surface. Start by laying the tub on a drop cloth to protect the surface underneath. Then, clean the tub with an aqueous alkaline cleaner, detergent solution, or a compatible solvent to remove any oily residue and ensure the surface is free from soap residue, release agents, and particulates. Rinse with clear water and allow the tub to dry completely.
Next, you'll want to sand the tub with fine sandpaper, such as 300-grit sandpaper, to create a rough surface that will help the primer and paint adhere better. Wipe away any sanding dust with a tack cloth or a damp cloth to ensure the surface is clean and dry.
Now, you are ready to apply the primer. If your tub has curves and bends, it is recommended to apply the primer in brief, intermittent bursts rather than a long, steady stream to avoid runs. Use a roller for open, easy-to-reach surfaces and a paintbrush to cut in the hard-to-reach areas. Allow the primer to dry adequately before proceeding to the next step. Refer to the instructions on your chosen primer for the recommended drying time.
It is important to choose a primer that is compatible with ABS plastic. Visit your local auto parts store and look for a primer specifically formulated for ABS. You can also use an adhesion promoter, which is designed to stick to any surface. Additionally, consider using a primer with a light gray color, as it has proven effective in the past for similar projects.
Once the primer is dry, you can proceed to the painting stage, followed by a topcoat to seal in the paint and add extra shine.

Paint the tub
Painting an ABS plastic tub requires a few steps to ensure a professional and long-lasting finish. Firstly, it is imperative to have the correct safety gear, including a face mask and gloves, to protect your skin and respiratory system. Cover the floor to catch any paint drips, and use masking tape to protect the taps and plug holes.
The first step is to ensure the tub is clean and dry. Use a bathroom cleaner and an abrasive sponge to thoroughly clean the tub, and then sand the tub with fine sandpaper. It is important to note that the grit of the sandpaper should be fine enough to prevent scratches or gouges on the surface, which will show through the paint. After sanding, wipe the tub to remove any traces of grit and ensure it is completely dry.
Next, you will need to apply a bonding agent to help the paint adhere to the surface. Use a roller for open surfaces and a paintbrush for hard-to-reach areas. Once the bonding agent is dry, follow the package instructions and apply the paint primer. Allow the primer to dry adequately before applying the paint.
Now, you can apply the paint. Take your time to apply the paint evenly to the entire tub. Allow sufficient drying time, following the paint manufacturer's instructions, and then apply a second layer if necessary.
Finally, finish with a layer of acrylic topcoat to seal in the paint and add extra shine. This will also help to protect your paint job and ensure its longevity.
