Painting a fiberglass bathtub is a great way to refresh the look of your bathroom without the hassle and expense of replacing the entire tub. While it is possible to paint a fiberglass tub, it's important to note that not all paints are created equal, and some may not adhere well to the surface or stand up to the heat and moisture of a bathtub. One popular option for painting a fiberglass tub is to use a specialty kit labelled for tubs and tiles, often available at home improvement stores or online. These kits typically include an epoxy-based paint that offers good adhesion and durability. However, it's important to follow the manufacturer's instructions carefully and ensure proper ventilation during the painting process due to the strong odour of epoxy paint. With the right preparation and products, you can give your fiberglass tub a new lease on life!

Prepping a fibreglass tub for painting
Step 1: Clean the Tub
Start by thoroughly cleaning the fibreglass tub to remove any dirt, soap scum, or grease buildup. Use a degreaser or a strong cleaner to ensure the surface is free of any grime. Rinse the tub well and ensure it is completely dry before proceeding to the next step.
Step 2: Sand the Surface
Lightly sand the entire surface of the tub. Sanding creates a rough texture that will help the paint adhere better. Use fine-grit sandpaper (around 320-grit) and sand in smooth, even strokes to avoid creating deep scratches. Sanding should be done carefully and thoroughly, covering every square inch of the tub's surface.
Step 3: Wipe Down with Alcohol
After sanding, wipe down the tub with alcohol to remove any dust or residue left behind. This step ensures that the paint will have a clean surface to adhere to and helps create a smooth finish.
Step 4: Protect Surrounding Areas
Before painting, protect the areas around the tub that you do not want to get painted. Use drop cloths, tape, and plastic sheeting to cover nearby walls, floors, and fixtures. Ensure that any vents or openings are also covered to avoid spray residue escaping.
Step 5: Choose the Right Paint
Select a paint designed for fibreglass surfaces and heavy water exposure. Epoxy-based paints, such as Rust-Oleum's epoxy appliance spray paint, are often recommended for fibreglass tubs due to their durability and ability to withstand moisture. You can choose between spray paint or paint that can be applied with a brush and roller.
By following these steps, you can effectively prepare a fibreglass tub for painting and achieve a professional-looking and long-lasting finish.

Recommended fibreglass tub paints
Painting a fibreglass tub can restore its appearance at a fraction of the cost of replacement. Before applying the paint, it is important to prepare the surface by thoroughly cleaning the tub and, in some cases, sanding it. While there are many types of paint that can be used on fibreglass tubs, some of the most recommended ones include:
Epoxy Paint
Epoxy paint is one of the most effective options for fibreglass tubs. It is renowned for its durability, water resistance, and scratch resistance. It provides a long-lasting finish, but it requires precise preparation and swift use once mixed. To ensure proper application, it is important to carefully follow the manufacturer's instructions.
Acrylic Latex Paint
Acrylic latex paint is another good choice for fibreglass tubs. It is water-resistant and provides a hard-wearing, durable finish, especially when applied over a latex primer. This water-based paint is convenient to apply, environmentally friendly, and holds up well to cleaning. It is also less likely to crack or peel off compared to other types of paint.
Rust-Oleum Epoxy Spray Paint
Rust-Oleum's epoxy spray paint is a highly recommended option by Amazon reviewers for updating a fibreglass tub. It can help bring back the shine to a tub that has yellowed over time. While it may show some wear if objects are placed inside the tub, it generally provides a long-lasting finish.
Topside Marine Paint
Topside marine paint is another option recommended by a user who has successfully used it to paint their fibreglass boat every 3-4 years. The process involves cleaning the tub, scuff sanding it, wiping it down with alcohol, and then painting it with a foam roller.
Homax Tough as Tile Aerosol Kit
The Homax Tough as Tile Aerosol Kit is another option that has been used by some users with varying results. It requires multiple coats to achieve the desired coverage, and even then, it may start to fail around the drain after a few months.
When choosing a paint for a fibreglass tub, it is important to consider the preparation required, the durability of the paint, and the ease of application. Asking for advice from a store associate or plumber can also be helpful in selecting the right paint for your specific needs.

Painting techniques
Painting a fibreglass tub is a cost-effective way to transform your bathroom. There are a few methods you can use, depending on the style of the tub and the finish you want to achieve.
Firstly, you must prepare the surface. Clean the tub thoroughly, and sand it down. It is important to note that some sources suggest that a lack of preparation is the main reason DIY tub painting jobs fail. You can then wipe the tub down with alcohol.
Next, you can apply the paint. One option is to use a two-part epoxy paint, which is available from hardware stores and online. You can apply this with a brush or roller, but some sources suggest that a slick finish is hard to achieve this way. Alternatively, you can use an aerosol kit, such as the Homax Tough as Tile kit, or a spray paint, such as Rust-Oleum's specialty spray paint. These options are more time-consuming, as they require multiple thin coats, but they can give a more even finish.
Finally, you should allow the paint to dry for several days before using the tub.

Post-painting care
Painting a fibreglass tub requires careful preparation and the right products. Once the painting is complete, there are several steps you can take to care for your newly painted tub and ensure the paint lasts.
Firstly, it is important to allow the paint to cure fully. This can take several days, depending on the product used and the number of coats applied. Ensure the area is well-ventilated and avoid using the tub during this time.
Once the paint has fully cured, it is essential to maintain good cleaning and maintenance practices. Regular cleaning will help to keep the tub in good condition. Use mild, non-abrasive cleaning products and avoid harsh chemicals or abrasive sponges, as these can damage the paint.
It is also important to avoid placing heavy or sharp objects directly on the tub's surface, as this can cause scratches or chips in the paint. If something is placed on the tub, such as a laundry basket, be sure to lift it rather than drag it, to avoid causing any damage to the paint.
Additionally, keep the tub well-ventilated and dry after use. Moisture can lead to the growth of mould or mildew, which can damage the paint and underlying surface.
Finally, be mindful of any signs of wear or peeling. If the paint begins to lift or chip, it may be necessary to re-coat the affected area or apply a new top coat to protect the underlying paint and surface.
By following these steps, you can help to ensure the longevity of your painted fibreglass tub.

Longevity of paint
The longevity of paint on a fibreglass tub depends on several factors, including the type of paint used, the preparation of the surface, and the frequency of use.
One of the most popular options for painting a fibreglass tub is to use an epoxy-based paint, such as Rust-Oleum's epoxy spray paint or a similar product. These paints can provide a durable finish that can last for several months or even years if properly applied and maintained. However, some users have reported issues with peeling and wear, even when following the manufacturer's instructions for surface preparation and application.
To maximise the longevity of the paint, it is crucial to thoroughly clean and sand the tub's surface before painting. Some sources recommend using a degreaser and then rinsing multiple times to ensure no soap scum or residue is left behind, as this can cause paint failure. Additionally, scuffing or sanding the surface can create a rougher texture for the paint to adhere to, improving its durability.
The frequency of use and proper care of the painted tub can also impact its longevity. Regular use and cleaning may result in more wear and tear, potentially causing the paint to chip or peel over time. It is recommended to avoid abrasive cleaners and brushes when cleaning a painted fibreglass tub, opting instead for gentle cleaning methods using soft cloths or rags and mild, naturally derived soap.
While some users have reported success with DIY methods, others have opted for professional bathtub resurfacing services. These companies may offer warranties for their work, providing peace of mind and assurance of the paint's longevity. However, the cost of professional services can be significant, sometimes comparable to the price of a new tub.
In summary, the longevity of paint on a fibreglass tub depends on the type of paint, the preparation of the surface, and the care and frequency of use. While epoxy-based paints and proper surface preparation can improve durability, regular wear and tear, and improper cleaning can still lead to peeling and chipping over time. Professional services may offer longer-lasting results but at a higher upfront cost.
