8 Step-by-step Guidelines on How to Paint Metal Bathtub

Step 1: Clean the Tub

Start by cleaning the bathtub thoroughly with a mild detergent and warm water. Use a sponge or cloth to scrub away any dirt, grime, or soap scum on the surface. For tougher stains, you can use a TSP cleaner.

Once the tub is clean, rinse it thoroughly with water and let it dry completely.

Step 2: Sand the Surface

Using medium grit sandpaper, lightly sand the entire surface of the bathtub. This will help roughen up the surface and create a better bond between the paint and metal. Once done, wipe away any dust or debris with a cloth.

Next, use fine grit sandpaper to smooth out any rough spots or imperfections on the tub’s surface. Again, make sure to clean off an dust or debris before moving on to the next step.

Step 3: Tape Off Any Areas You Don’t Want to Paint 

Before you start painting, use painter’s tape to mask off any areas of the bathtub or surrounding surfaces that you don’t want to paint. This includes the edges near the walls, the drain, faucet, handles, and any other fixtures.

Carefully apply the tape to create clean, crisp lines, ensuring it is firmly pressed down to prevent paint from seeping underneath. Taking the time to tape thoroughly will help achieve a professional-looking finish and make cleanup much easier.

Step 4: Apply the Primer

Using a high-quality paintbrush, apply an epoxy-based primer to the bathtub’s entire surface. This will help create a smooth and durable base to which the paint can adhere. Make sure to follow the manufacturer’s instructions for drying time between coats.

It’s best to apply at least two coats of primer, allowing each coat to dry completely before applying the next.

Step 5: Paint the Tub

Once the primer is fully dry, it’s time to paint your metal bathtub. Use a high-quality paint suitable for metal surfaces and mix it according to the manufacturer’s instructions.

Using a foam roller, start painting from one end of the tub, working in small sections at a time. Make sure to apply an even coat of paint and smooth out any drips or bubbles as you go.

Remember to follow the direction of the grain when painting to achieve a professional finish. It may also help to use long, overlapping strokes for a smoother application.

Step 6: Apply Multiple Coats

To achieve full coverage and a vibrant color, it’s essential to apply multiple coats of paint. Allow each coat to dry fully before applying the next, following the manufacturer’s instructions for drying time.

Depending on the color and type of paint you’re using, you may need to apply three or more coats for optimal results.

Step 7: Let the Paint Cure

Once you’ve applied all your desired coats of paint, let the bathtub cure according to the manufacturer’s instructions. This will ensure that the paint fully adheres to the surface and is durable enough for everyday use.

You may need to wait a few days before using the bathtub again, so be sure to plan accordingly.

Step 8: Remove the Tape and Enjoy Your Newly Painted Bathtub

Once the paint is fully cured, carefully remove the painter’s tape from around the tub. This will reveal clean edges and lines for a professional-looking finish.

Now, you can enjoy your freshly painted metal bathtub and admire how it has transformed your bathroom’s overall look.

Following these step-by-step guidelines on How to paint metal bathtub will ensure that you achieve a beautiful and long-lasting finish when painting your metal bathtub.
