How to Paint an Acrylic Freestanding Bath tub: A Step-by-Step Guide for a Fresh, Modern Look

An acrylic freestanding bathtub can be a striking focal point in any bathroom, but over time, it might lose its original luster or simply not match your style anymore. Repainting your tub is a cost-effective way to refresh its appearance without having to replace it. In this guide, we’ll walk you through each step of painting an acrylic bathtub, from prepping the surface to applying the final coat. With the right approach and materials, you can achieve a professional, durable finish.

Why Paint an Acrylic Bathtub?

Painting an acrylic bathtub isn’t just about aesthetics. While the primary goal is to improve the look of your tub, painting can also protect the surface, prevent wear, and extend its lifespan. Choosing the right paint and following the correct steps can give your tub a fresh look that withstands daily use.

Important Considerations Before You Begin

Before diving in, there are a few things to consider:

1. Choose the Right Paint: For acrylic tubs, use a high-quality, waterproof epoxy or acrylic urethane paint designed for bathroom or tub surfaces. Regular paint won’t bond well to acrylic and could peel quickly.
2. Ventilation: Painting a bathtub involves fumes, so ensure the bathroom is well-ventilated by opening windows or using fans.
3. Allow for Drying and Curing Time: Plan your painting project when you can allow ample drying and curing time, as some epoxy paints may require several days to fully cure.

Tools and Materials You’ll Need

Before you start, gather these essential tools and materials:

• Sandpaper (120 and 220 grit)
• Drop cloths and painter’s tape
• Cleaning solution (dish soap or a tub cleaner)
• Microfiber cloths
• Waterproof epoxy or acrylic urethane paint
• Paint roller (foam roller recommended) and paintbrushes
• Respirator mask
• Gloves and safety goggles
• Tack cloth
• Primer (optional, based on paint type)
• Clear coat for added durability (optional)

Step 1: Clean and Prep the Tub Surface

A clean surface is key for any painting project, especially with acrylic tubs. Proper cleaning will help the paint adhere better and ensure a smoother, longer-lasting finish.

1. Scrub the Tub: Use a gentle cleaner or dish soap and water to thoroughly scrub the tub, removing any soap scum, oils, or residues. Pay special attention to hard-to-reach spots and around the base.
2. Rinse and Dry: Rinse off the cleaner completely with warm water and dry the tub with a microfiber cloth. Avoid leaving any water spots, as these can interfere with paint adhesion.
3. Remove Fixtures (If Possible): If there are any removable fixtures or drain covers on your tub, take them off to avoid paint drips and give yourself better access to the tub’s surface.

Step 2: Sand the Surface

Sanding the tub will create a slightly rough surface, helping the paint adhere better. This is an essential step, as the smooth surface of acrylic doesn’t hold paint well without some texture.

1. Start with 120-Grit Sandpaper: Use 120-grit sandpaper to gently sand the entire tub surface. Be thorough, but don’t press too hard—you’re aiming to create a slightly rough texture, not deep scratches.
2. Switch to 220-Grit Sandpaper: After the initial sanding, go over the surface again with 220-grit sandpaper to smooth out any larger scratches left from the first round. This will create an even, ideal surface for paint adhesion.
3. Wipe with a Tack Cloth: Use a tack cloth to remove all dust and sanding residue. A clean surface is crucial to ensure an even paint application.

Step 3: Protect the Surrounding Area

Painting can be messy, so protect any areas you don’t want to paint.

1. Use Painter’s Tape: Apply painter’s tape along the edges where the tub meets the floor or walls. This will give you clean, sharp lines and prevent paint from spilling onto other surfaces.
2. Lay Down Drop Cloths: Place drop cloths around the base of the tub to catch any drips or spills during painting.
3. Ventilate the Room: Open windows and use a fan if possible. Painting can release fumes, and good ventilation is essential for a safe and comfortable working environment.

Step 4: Prime the Tub Surface (If Needed)

Depending on the type of paint you’re using, you may need a primer. Check the instructions on your paint to see if it recommends using a primer on acrylic surfaces.

1. Apply Primer (If Required): If your paint requires a primer, apply a thin, even coat across the entire tub using a foam roller or brush.
2. Allow Primer to Dry: Follow the manufacturer’s instructions on drying time. Make sure the primer is completely dry before moving on to painting.

Step 5: Paint the Tub

Now, it’s time for the main step—painting your tub. Use an epoxy or acrylic urethane paint for best results, as these are designed to withstand moisture and daily use.

1. Apply the First Coat: Pour the paint into a roller tray and load a foam roller for smooth, even application. Start at the top of the tub and work your way down, applying a thin, even layer. Use a paintbrush to get into corners and around fixtures.
2. Avoid Overlapping Too Much: Try to keep a wet edge as you work to avoid brush marks or streaks. Lightly overlap each pass, but avoid going over areas that are already drying.
3. Let the Paint Dry: Allow the first coat to dry completely according to the paint’s instructions. This can take anywhere from 6 to 24 hours, depending on the product.
4. Apply a Second Coat: For best coverage, apply a second coat once the first has dried. Follow the same technique, using thin, even layers. Two coats are generally sufficient, but a third coat may be applied if you want a richer color or deeper coverage.

Step 6: Apply a Clear Coat (Optional)

A clear topcoat can provide additional durability and protection against chips or scratches. Many tub paints don’t require this, but if you want extra protection, it’s a good option.

1. Apply Clear Coat: Once the final coat of paint is completely dry, use a foam roller to apply a thin layer of clear coat. This will add shine and protect your paint from wear.
2. Allow to Cure Fully: Clear coats often take 24-48 hours to dry fully. Avoid touching or using the tub during this time.

Step 7: Remove Tape and Clean Up

Once the paint is dry and the clear coat is applied, it’s time to tidy up and admire your work.

1. Remove Painter’s Tape: Gently pull off the painter’s tape while the paint is still slightly tacky. This helps prevent chipping along the edges.
2. Reattach Fixtures: If you removed any fixtures, now is the time to put them back in place. Make sure all connections are secure and any caulking is reapplied if necessary.

Step 8: Let the Paint Cure Completely

For the best results, allow the paint to cure fully before using the tub. Most paints recommend a curing time of 72 hours, although some epoxy paints may take up to a week. Avoid placing any heavy items in the tub or filling it with water during this time.

Maintenance Tips for Your Painted Acrylic Tub

To extend the life of your freshly painted tub:

• Clean Gently: Use non-abrasive cleaners and a soft cloth to keep your tub clean without scratching the paint.
• Avoid Harsh Chemicals: Bleach, ammonia, or harsh bathroom cleaners can weaken the paint over time. Opt for mild soap or a dedicated acrylic cleaner.
• Wipe Down After Use: To prevent water spots or soap scum buildup, wipe the tub dry after each use.
