By the end of this guide, you’ll be equipped with the knowledge to decide if this project is right for you and how to achieve a smooth, lasting finish that can make your bathtub look and feel brand new.

Preparing the Bathtub Surface

Proper preparation of the bathtub surface is crucial to ensure the paint adheres well and lasts. Start by thoroughly cleaning the tub to remove soap scum, oils, and dirt. Use a heavy-duty bathroom cleaner or a mixture of bleach and water to disinfect and strip away any residues. Rinse thoroughly and allow the tub to dry completely.

Next, sand the entire surface of the bathtub using fine-grit sandpaper (around 220 grit). This step helps to create a slightly rough texture for the paint to bond. Be sure to sand evenly and pay attention to glossy or smooth areas. After sanding, vacuum or wipe away all dust using a damp cloth and allow the tub to dry.

If your bathtub has any chips, cracks, or damage, repair these areas with a two-part epoxy filler designed for porcelain or fiberglass. Follow the manufacturer’s instructions for mixing and application. After the filler cures, sand the repaired spots smooth and clean the surface again.

Finally, tape off surrounding areas such as faucets, drains, and tiles using painter’s tape to protect them from paint. Cover the floor and any fixtures with drop cloths or plastic sheeting.

Choosing the Right Paint and Tools

Selecting the appropriate paint and tools is essential for a professional finish and durability. Bathtubs require paints that are water-resistant, durable, and able to withstand frequent cleaning and exposure to moisture.

Recommended Paint Types:

  • Epoxy paint: Offers excellent adhesion, durability, and water resistance. Often comes in two parts that must be mixed before application. Ideal for fiberglass and porcelain tubs.
  • Acrylic urethane paint: Provides a smooth finish and good durability, suitable for bathtubs with minimal wear.
  • Rust-oleum or specialty bathtub refinishing kits: These kits include paint and primers designed specifically for bathtubs, simplifying the process.

Essential Tools:

  • Fine-grit sandpaper (220–320 grit)
  • High-quality synthetic bristle paintbrushes for edging
  • Foam roller with a smooth finish for large areas
  • Painter’s tape
  • Protective gloves and mask
  • Mixing stick (if using multi-part paint)
Paint Type Best For Durability Ease of Application Drying Time
Epoxy Paint Porcelain, Fiberglass High Moderate (requires mixing) 12-24 hours
Acrylic Urethane Light Wear Bathtubs Moderate Easy 6-12 hours
Bathtub Refinishing Kits All Types High Easy (pre-packaged) 12-24 hours

Applying Primer and Paint

Begin the painting process by applying a high-quality bonding primer, especially if you are working with a smooth porcelain or fiberglass surface. Use a small brush for corners and a foam roller for larger areas. The primer enhances paint adhesion and prevents peeling.

Allow the primer to dry fully according to the product instructions before proceeding to paint. Apply the paint in thin, even coats to avoid drips and uneven texture. Using a foam roller will help achieve a smooth, consistent finish on the flat surfaces of the tub, while a brush is better for edges and intricate areas.

Typically, two to three coats of paint are recommended for optimal coverage and durability. Allow each coat to dry completely before applying the next, adhering to the drying times specified on the paint label. Maintain good ventilation in the workspace to facilitate drying and reduce fumes.

Finishing and Curing the Painted Bathtub

After the final coat of paint has been applied and dried, inspect the surface for any imperfections such as bubbles, runs, or rough spots. Lightly sand these areas with very fine sandpaper (320–400 grit) and wipe clean to smooth the finish.

Some products recommend applying a clear protective topcoat or sealer to enhance the durability and gloss of the paint. If so, apply this according to manufacturer instructions after the paint has fully cured.

Curing time is critical; avoid using the bathtub for at least 48 to 72 hours after painting to allow the paint to harden completely. Longer curing times (up to 7 days) may be necessary for full chemical resistance, so follow product-specific guidelines closely.

Tips for Maintaining a Painted Bathtub:

  • Avoid abrasive cleaning tools or harsh chemicals.
  • Use gentle, non-abrasive cleaners.
  • Wipe the surface dry after use to prevent water spots and damage.
  • Address any chips or damage promptly to prevent further deterioration.

By carefully preparing, selecting the right materials, and following proper application and curing procedures, you can achieve a professional-quality painted bathtub that revitalizes your bathroom.

Preparing the Bathtub Surface for Painting

Proper preparation is critical to ensure that the paint adheres well and provides a durable, attractive finish. Follow these steps carefully before applying any paint to your bathtub:

Clean the Surface Thoroughly

  • Remove all soap scum, oils, and dirt using a strong household cleaner or a mixture of trisodium phosphate (TSP) and water.
  • Scrub the surface with a non-abrasive sponge or brush to avoid scratching the bathtub.
  • Rinse thoroughly with clean water and allow the tub to dry completely.

Remove Old Caulk and Repair Damage

  • Use a utility knife or caulk remover tool to remove any old caulk around the edges.
  • Inspect for chips, cracks, or gouges; fill these imperfections with an epoxy or bathtub repair kit according to manufacturer instructions.
  • Sand the repaired areas smooth once dry.

Sand the Entire Bathtub

  • Use medium-grit sandpaper (around 220 grit) to lightly sand the entire surface to be painted.
  • This step promotes adhesion by roughening the glossy finish of the tub.
  • After sanding, wipe down the bathtub with a damp cloth to remove all dust and debris.

Choosing the Right Paint and Tools

Selecting the appropriate materials is essential for a long-lasting and professional-looking finish.
