Painting a porcelain bathtub is cheaper than replacing it
Painting a porcelain bathtub is a cost-effective alternative to replacing it. Bathtubs are often the focal point of a full bath, and if yours is pitted, chipped, scratched, or simply a colour that no longer suits your style, you may want to change it. However, ripping out and replacing a bathtub can be expensive and bothersome. Instead, you can refresh the look and achieve a high-gloss finish by painting it with a specialty kit labelled for tubs and tiles. These kits are available at most home centres for about $25.
One popular option is Rust-Oleum's Tub & Tile Refinishing Kit, which has received positive reviews from DIY enthusiasts. Epoxy paint is an incredibly sturdy option for refinishing a bathtub and can withstand daily use without chipping or streaking. It is important to follow the proper steps when painting a porcelain bathtub to ensure a long-lasting finish. This includes filling any scratches or chips with epoxy putty, sanding the entire bathtub, and ensuring the tub is clean and dry before painting.
Additionally, it is crucial to use painter's tape to protect the surrounding tiles and fixtures. The room should also be well-ventilated due to the strong odour of epoxy paint. Once the paint is applied, follow the manufacturer's instructions for drying time, as epoxy can take time to fully cure. After the paint has cured, remove the tape, re-caulk the tub, and reinstall any fixtures and drain hardware.
Painting a porcelain bathtub is a cheaper and more accessible option than replacing it. It allows you to transform the look of your bathtub and give it a like-new finish without incurring the cost and hassle of a full replacement. With the right preparation and care, you can achieve a durable and aesthetically pleasing result that will last for years.

Epoxy paint is durable and long-lasting
Yes, you can paint a porcelain bathtub. In fact, if your porcelain bathtub is pitted, chipped, or scratched, painting it with epoxy is a great way to refresh its colour and finish without the bother and expense of ripping it out and replacing it. Epoxy paint is durable and long-lasting, and it boasts great adhesion.
Epoxy paint is highly durable, resilient, and long-lasting. It is a versatile product that can be used in many different places, from bathrooms to garages and workshops. It is easy to apply, but it can be a lengthy process if several layers are required. At the very least, two coats are needed to ensure even coverage. The most important part of the application is prepping the surface. Epoxy paint does not need a primer, but the surface must be free from dirt, grime, and oil to ensure the paint adheres correctly.
Epoxy paint is made of a mix of latex acrylic with a small amount of epoxy. The acrylic portion of the paint gives it versatile colour options, including metallics. The epoxy adds durability, making it popular for floors. The combination of acrylic and epoxy creates a paint that stands up to heavy use and resists common stains. It is made in varying ratios of the carrying agent to epoxy, with paints that have a higher epoxy content being more durable.
Epoxy paint is a great choice for basement and garage floors. It can bear the brunt of heavy shock, heat, chemicals, and water. It is also naturally moisture-resistant. Spills and stains won't be absorbed into the epoxy, leaving ugly, lasting marks. It is also dust-resistant because it is a topical sealer, creating a protective barrier.
Epoxy paint can be hard to remove and may yellow over time, especially when in direct sunlight. However, this is less likely with epoxy paint than with epoxy resin, and you may not notice any discoloration with darker colours.

Preparation is key: clean, repair, sand, and ventilate
Painting a porcelain bathtub is a great way to refresh the look of your bathroom, but it's important to remember that preparation is key. Before you start painting, you need to clean, repair, sand, and ventilate the area to ensure a smooth and professional finish.
Clean
Start by giving your bathtub a good clean to remove any dirt, grease, or debris. You can use a basic scrubbing technique with a soft sponge and a mixture of hot water and dishwashing soap. Avoid using abrasive cleaners, scouring powders, vinegar, or steel wool, as these can damage the finish of your bathtub. Once the surface is free from grease and dirt, wipe it down with a large sponge and trisodium phosphate to ensure it is perfectly clean before painting.
Repair
Before painting, it's important to address any chips or scratches on the surface of the bathtub. Use leftover paint or repair kits to touch up these areas and prevent further damage. Filling in these imperfections will create a smooth base for your new paint and ensure that your bathtub has an even finish.
Sand
Sanding is a crucial step in the preparation process. It helps create a rough surface for the paint to adhere to, preventing peeling or chipping later on. Use sandpaper or an emery cloth to roughen up the surface of the bathtub, paying attention to any areas that may be especially smooth or glossy. It is important to note that you should not over-sand the surface, as this can create more work in the long run. Simply roughen the surface enough for the paint to adhere properly.
Ventilate
When painting a porcelain bathtub, it's important to consider ventilation. Epoxy-based paints produce powerful vapors, so open all windows and use fans to create good airflow. Avoid blowing air directly over the tub or the paint, as this can interfere with the drying process. If possible, consider using an air purifier to help remove odors and pollutants from the air. Additionally, wear a ventilator or N95 mask to protect yourself from inhaling paint fumes.

Use bathtub and tile paint, not regular spray paint
Yes, you can paint a porcelain bathtub. It is easier, faster, and less expensive than replacing the entire bathtub. The best paints for a porcelain bathtub will withstand water and work well with the material. You can use acrylic polymer, polyurethane, or epoxy-based paint. However, it is important to note that you should not use regular spray paint on a porcelain bathtub.
Regular spray paint is not designed for use on surfaces that are constantly immersed in water. It will not adhere properly to the porcelain surface and will eventually bubble, peel, and crack. Additionally, the spray from regular spray paint goes everywhere and is very difficult to clean up. Therefore, it is important to use a specialised bathtub and tile paint product.
Bathtub and tile paint products are designed to withstand the heat and moisture that bathtubs are exposed to daily. They also provide a high-gloss finish that is durable and long-lasting. These products are available as epoxy or enamel paints and are suitable for use on porcelain, ceramic, and fiberglass tubs.
When using a bathtub and tile paint product, it is important to follow the manufacturer's instructions carefully. The application process typically involves cleaning and sanding the surface, masking off the area, and then applying the paint with a sprayer, roller, or brush. It is also important to ensure proper ventilation during the painting process.
By using a specialised bathtub and tile paint product and following the recommended application process, you can achieve a durable and aesthetically pleasing finish on your navy blue porcelain bathtub.

Consider hiring a professional for better results
Painting a bathtub is a great way to save money and prevent one less item going to the landfill. While it is possible to paint a bathtub yourself, it is a tricky process that requires skill, preparation, good-quality supplies, and several coats of paint. For this reason, it may be worth hiring a professional to achieve better results.
Professional bathtub refinishers have the proper tools, access to high-quality products, and the experience to do the job correctly. They have commercial-grade products that will make a difference in the longevity of your refinished tub. A DIY paint job will last a maximum of three to four years, whereas a professionally painted bathtub can last up to 10 to 20 years with proper maintenance.
The cost of a professional refinishing service ranges from $500 to $750, which is more expensive than a DIY kit, but still cheaper than a full bathtub replacement, which can cost upwards of $1,000. If you are adept at home remodelling, you may be able to replace your tub for $500 to $800, but this is still more costly than hiring a professional to paint it.
If you do decide to paint your navy blue porcelain bathtub, the best type of paint to use is an epoxy-based paint. This type of paint is durable and long-lasting, and it can be colour-matched to your desired shade. However, it is a tricky process that requires multiple steps and careful preparation, so it is important to follow the manufacturer's instructions and allow adequate drying time.
