Preparation and supplies
Painting a plastic bathtub in a mobile home is a great DIY project to improve the look of your bathroom. It is important to prepare the surface of the bathtub and have the right supplies to ensure a professional and lasting finish.
Firstly, ensure you have the right paint for the job. You will need a paint that is specifically formulated for plastic. A top-quality acrylic enamel paint is recommended. You will also need a paint primer and a sealant. Rustoleum makes a line of specialty paints and primers that can be used on plastic. Their tub and tile refinishing kit is one of the most popular products on the market and includes a two-part epoxy paint.
Next, you will need to prepare the surface of the bathtub. Clean the area around the bathtub to remove any soap particles, grime, and hair. Apply a cleanser to eliminate any waste or grease and leave the surface spotless. You can use a product like limeAway or a natural cleanser like baking soda or vinegar. If your bathtub is made of fiberglass, you can use an auto polish compound to make it shine again. If your fiberglass has scratches, try using a white polishing compound applied with a soft cloth. Once the bathtub is clean, make sure it is completely dry.
Before painting, you will need to sand the bathtub to create a grip so that the paint will stick. Your refinishing kit should come with the right sandpaper for roughing up the surface. 120-grit sandpaper will work if you don't have a kit. After sanding, clean the bathtub again with a product like limeAway to ensure the surface is ready for painting.
Finally, use painter's tape to tape off the bathtub and protect the surrounding areas. Wipe the surface with a tack cloth to remove any dust and ensure it is completely dry.

Cleaning and drying the bathtub
Painting a plastic bathtub in a mobile home is a great DIY project to give your bathroom a new look. However, the key to success is preparation, and that includes cleaning and thoroughly drying your bathtub.
First, ensure the area around the bathtub is clean. This is important because you don't want soap particles, grime, or hair making the surface of your bathtub dirty. Next, apply a cleanser to eliminate any waste or grease, leaving the whole surface of the plastic bathtub spotless. You can use a variety of cleaning products for this step, including:
- Dishwashing detergent: Mix one ounce with a gallon of water and scrub with a sponge or plastic scrubbing pad.
- Baking soda: Create a paste with water and scrub the tub with a sponge.
- White distilled vinegar: Fill a spray bottle with vinegar, let it sit for a few minutes, and then scrub.
- Acetone: Wipe the acetone on the plastic with a soft cloth to remove stains caused by dye, paint, or pigments.
If your bathtub is made of fiberglass, you can also use a liquid cleaner or automotive white polishing compound applied with a soft cloth to make it shine again. Avoid using abrasive cleaners, as these can dull the surface and leave scratches.
Once you've cleaned the bathtub, it's crucial to ensure it's completely dry. Use a towel to thoroughly dry the tub, as even a single drop of water can interfere with the painting process.

Sanding the bathtub
To sand the bathtub effectively, you can use sandpaper or a similar abrasive material. If you have purchased a refinishing kit, it should come with the appropriate sandpaper. If not, you can use 120-grit sandpaper or follow Rustoleum's recommendation of #400/600 grit wet/dry sandpaper. Ensure that you cover the entire surface of the bathtub and don't miss any spots. This process will help create an even and consistent texture for the paint to adhere to.
Once you have finished sanding, it is important to clean the bathtub thoroughly. This step will remove any dust or debris created during the sanding process. You can use a product like limeAway or a mild cleanser to ensure that the surface is spotless. After cleaning, make sure to dry the bathtub completely. Any moisture on the surface can interfere with the painting process, so don't skip this step.
Before moving on to the next step, it is recommended to tape off the edges of the bathtub using painter's tape. This will help create crisp, clean lines and protect the surrounding areas from paint. Additionally, you can use a tack cloth to wipe down the surface, ensuring it is free of any remaining dust or debris. This attention to detail will ensure a professional-looking finish.

Priming the surface
Once you've cleaned and dried the surface of your bathtub, it's time to prime. Before you start, ensure the area is well-ventilated and you have protected yourself and the areas around the bathtub.
Firstly, you'll need to prepare the surface by sanding it. This will ensure the paint adheres properly. Use sandpaper to rough up the surface—your refinishing kit should come with the right sandpaper, but if not, 120-grit sandpaper will work. Be sure to sand the entire surface.
Next, use painter's tape to tape off the edges of the tub. Then, wipe the surface with a tack cloth to remove any dust. It's important to ensure the surface is completely dry and free of dust before priming.
Now, you're ready to apply the primer. Your bathtub refinishing kit should include a bonding agent to help the paint adhere. Apply this to the tub's surface using a roller for open surfaces and a paintbrush for hard-to-reach areas. Be sure to follow the instructions on your specific product. Allow the bonding agent to dry adequately before proceeding.
Once the bonding agent is dry, you can apply the primer as your base coat. Again, be sure to follow the instructions on your specific product. After applying the primer, give it enough time to dry properly before moving on to the next step.

Ensure the primer is also completely dry before moving on to the next step.
Paint:
Now, it's time to paint the tub. Use a top-quality acrylic enamel plastic tub paint and apply two coats for the best results. Before painting the whole tub, it is advisable to test the paint on a small section first. This will give you an idea of the final outcome. Ensure there is adequate ventilation in the area while painting.

Finally, once the paint is dry, apply a sealant to protect the new finish. Make sure to allow sufficient drying time before using the bathtub.
