What You'll Learn

Bathtub reglazing, or the professional process
Bathtub reglazing, also known as recoating, resurfacing, or refinishing, is a straightforward process that can help extend the life of a bathtub. It is a purely cosmetic procedure that can make an old bathtub appear new.
The professional reglazing process typically involves the following steps:
- Surface preparation: The surface of the bathtub is sanded down to make it even and smooth. Any cracks, chips, or worn areas are filled and repaired.
- Cleaning: The bathtub is thoroughly cleaned to remove any soap scum, debris, or foreign materials. This step is crucial as any residue can prevent the paint from adhering properly.
- Priming: A primer is applied to the surface of the bathtub. Multiple coats of primer may be sprayed on to ensure a consistent base.
- Painting: After the primer dries, the bathtub is painted with a stronger coat of finishing paint. This is typically done using an airless paint gun or roller, followed by a brush for the final touches. Multiple coats of paint may be applied for a smooth finish.
- Drying: The bathtub is allowed to dry for an extended period, often at least 24 hours. This ensures that the paint cures completely.
- Final touches: After drying, any tape or coverings are removed, and the bathtub is buffed to a shine. Fixtures and drain hardware are reinstalled, and the bathtub is ready for use.
The professional reglazing process can cost between $500 and $750, but it offers a longer-lasting solution compared to DIY methods. A well-maintained professional reglaze can last between 10 and 15 years, protecting the integrity of the bathtub. Without proper care, the reglazing may last for a shorter duration of 3 to 4 years.

Preparation and cleaning
Remove Old Caulk and Fixtures:
Start by removing any old caulk using a caulk removal tool, a spackling knife, or a 5-in-1 painter's tool. Carefully take out the drain hardware and any fixtures in the bathtub, using appropriate tools and following the necessary procedures.
Clean the Bathtub:
Open the windows and turn on the bathroom exhaust fan to ensure proper ventilation. Clean the bathtub thoroughly to remove any grime, soap scum, and mildew. You can use a 10% bleach solution in water for this step. Rinse the bathtub well and follow up with an abrasive bathroom cleanser.
Scour and Scrape:
Scour the tub with a scouring powder and scrub brush to remove any stubborn dirt or residue. After rinsing, use a razor blade to scrape away any remaining caulk, paint, or debris that the scrub brush couldn't remove. Gently run the razor at an angle across the surface to avoid scratching the tub.
Fill Cracks and Chips:
Repair any cracks, chips, or gouges with epoxy putty or a tub repair product. This will create a smooth and even surface for painting. Let the filler dry completely before proceeding to the next step.
Sand the Surface:
Use a 120-grit sanding block or electric orbital sander to sand the entire bathtub surface, including the areas you filled. This step helps create a rough surface for better paint adhesion. Wear a mask during sanding to avoid inhaling the dust. After sanding, rinse the bathtub again to remove any dust or residue.
Protect Surrounding Areas:
Use painter's tape to protect the surrounding areas that you do not want to paint, such as tile at tub level and fixtures around the bathtub. Run the tape along the floor, walls, and around the edges of your fixtures. If you have a window in the bathroom, you can also tape a fan to it to improve ventilation.
Ventilate the Area:
Ensure proper ventilation by opening windows or using a fan to keep the air circulating. Wear a respirator or mask to protect yourself from inhaling paint fumes, especially if using epoxy paint, as it can be strong-smelling.
Final Cleaning:
After sanding, give the bathtub a final rinse and wipe it dry with clean towels or rags. Let the tub air dry completely to ensure it is free of moisture before you start painting. This step is crucial for the paint to adhere properly.
Mix and Test the Paint:
Follow the manufacturer's instructions to mix the paint included in the tub refinishing kit. If using a two-part epoxy paint, combine the parts thoroughly before application. Test the paint's adhesion and appearance in a small, hidden area of the bathtub to ensure it performs as expected.
By following these preparation and cleaning steps, you will ensure that your bathtub is ready for a smooth and long-lasting paint job.

Materials and safety
Bathtub paint, also known as bathtub epoxy, is a specially formulated paint designed to withstand the moisture and heat that bathtubs are exposed to daily. Unlike ordinary paint, epoxy boasts great adhesion and long-lasting durability once cured. Bathtubs come in various materials, such as acrylic, fiberglass, porcelain, and metal, and the paint must be suitable for the surface. For example, if you have a cast iron tub, you should use paint suitable for metal, such as acrylic urethane enamel.
Before painting, the tub must be thoroughly cleaned to remove any dirt, scum, or debris, and a bleach-and-water solution can be used to eliminate mildew. Any chips or cracks should be repaired with filler, and the surface should be sanded to ensure the paint will adhere. It is important to remove the tub's existing caulk and metal drain, and to use painter's tape to protect the surrounding area. The room should be well-ventilated, and you should wear a respirator or mask to protect yourself from the epoxy fumes.
The paint is typically applied with an airless paint gun or a roller, and it is important to follow the manufacturer's instructions for mixing and application. Multiple coats are usually required, and the tub should be allowed to dry thoroughly between coats. Once the final coat is cured, the tape and plastic sheeting can be removed, and the tub can be re-caulked and reinstalled.
It is important to note that painting a bathtub is a temporary fix, and the paint job will likely last only a few years, whereas a professional reglazing job can last up to 10-20 years with proper maintenance.

Epoxy paint
Before applying epoxy paint, the bathtub surface must be properly prepared. This includes thoroughly cleaning the tub to remove any soap scum or debris, which can interfere with the paint's adhesion. Any existing damage, such as cracks, chips, or rusted areas, should be repaired with filler before painting. Once the surface is smooth and clean, it's important to follow the manufacturer's instructions for the specific epoxy paint product you're using.
After the final coat has dried, the tape can be removed, and any fixtures and drain hardware can be reinstalled. It's crucial to allow the paint to fully cure before using the bathtub, even if it feels dry to the touch. Once cured, the bathtub can be used and maintained as you would with any other porcelain surface.

DIY kits
Bathtubs can be painted, and it is a good way to improve the appearance of a tired-looking tub without the expense of replacing it. This process is known as reglazing. While it is possible to hire a professional reglazer, DIY kits are available for those who want to paint their own bathtub.
DIY bathtub painting kits are available from several brands, including Rust-Oleum, Bathworks, and Homax. These kits are intended to be complete, but you may need to add a second kit for more than two coats, especially if you want to paint the bathtub surround. Kits tend to be short on some items, so you may need to budget for additional materials.
The Rust-Oleum Tub and Tile Kit is an epoxy paint that can be used to refresh your ceramic, porcelain, or fiberglass tub. It is available from Amazon and Home Depot for around $25. The kit does not come with primer, but some users recommend using a wipe-on TubCast primer with a microfiber cloth before painting. The kit also has poor instructions, so it is worth reading blog posts, customer reviews, and watching videos before starting the project.
The Bathworks Roll-On Refinishing Kit is another option, ideal for those seeking a high-quality, cost-effective way to refresh their bathroom surfaces. It is suitable for bathtubs, sinks, tiles, and countertops and provides a professional finish. The EZ Etch Kit is recommended for cast iron, steel, porcelain, and ceramic fixtures to ensure the best possible adhesion.
Before painting your bathtub, it is important to follow the correct preparation steps. The tub must be thoroughly cleaned, with any soap scum or debris removed, as this will prevent the paint from bonding. Any rusted areas in metal bathtubs must be cleaned and filled, and the tub should be scoured with a razor blade and sanded to ensure the paint coating will adhere. Painter's tape should be used to protect the walls, floor, and any fixtures around the bathtub.
When painting, it is important to follow the manufacturer's instructions. Many kits use a two-part epoxy paint that must be combined before application. The paint should then be applied in thin, even coats, with any drips smoothed out as you go. The first coat should be allowed to dry according to the manufacturer's instructions before the second coat is applied. It is important to note that the tub cannot be used until the paint has fully cured, which will take longer than the drying time. Once cured, the tape can be removed, and the tub can be re-caulked and reinstalled.
Overall, DIY bathtub painting kits provide a cost-effective way to refresh your bathtub, but it is important to follow the correct preparation and application steps to achieve the best results.
