Painting a bathtub can completely transform the look of your bathroom. With some preparation and the right materials, it’s possible for many bathtub types to get a fresh coat of paint. There are some factors to consider before taking on a bathtub paint job. Read on to learn if you can paint your bathtub and how to do it right.
Can You Paint a Porcelain, Fiberglass or Acrylic Bathtub?
Porcelain, fiberglass and acrylic are common bathtub materials that can accept paint, provided proper preparation and paint types are used:
Porcelain Bathtubs
Porcelain enamel bathtubs have a glasslike coated surface that can be painted. The porcelain surface must be sanded and primed properly before painting to ensure adhesion. Using a high quality enamel or epoxy paint made for bathtub surfaces is recommended for porcelain.
Can you paint a porcelain bathtub?
Yes, porcelain bathtubs can be painted but require more extensive surface preparation than other materials. The slick porcelain surface must be sanded thoroughly and primed to ensure paint adhesion.
Fiberglass and Acrylic Bathtubs
Fiberglass and acrylic bathtubs have textured surfaces that allow for better paint adhesion. Make sure to scuff sand glossy acrylic tubs before painting. For both materials, use a 100% acrylic latex tub and tile paint. Epoxy paints can also work well.
Can you paint a fiberglass or acrylic bathtub?
Yes, fiberglass and acrylic bathtubs can be painted. Their porous surfaces don’t require as aggressive sanding as porcelain. Ensure the surface is clean and lightly sanded before painting with a tub and tile paint.
What Kind of Paint Do You Use on Bathtubs?
Choosing the right type of paint formulated for bathtub surfaces is key to getting great results painting over porcelain, acrylic or fiberglass. Here are some top options:
- Enamel paint – Two-part epoxy enamel paints provide the most durable finish on porcelain tubs. Ensure it’s made for use on bathtubs.
- Acrylic latex tub & tile paint – 100% acrylic latex paints with silicone offer maximum adhesion and have some flexibility. Ideal for fiberglass and acrylic.
- Epoxy paint – Epoxy paints work well on all tub materials. They offer superior adhesion and a long-lasting, protective finish.
- Spray paint – Avoid using regular spray paints on bathtubs as they may not adhere well or be waterproof. Use specialty tub and tile spray paint instead.
Avoid using regular wall paints or oil-based paints, as they won’t properly adhere to slippery bathtub surfaces when exposed to moisture over time. Investing in the right tub paint will help ensure great results.
What Are the Steps to Paint a Bathtub?
Painting a bathtub takes some preparation and careful application of paint. Here is an overview of the process:
1. Clean and Remove Existing Finish
Thoroughly clean the tub with detergent, rinse and let dry. Use chemical paint strippers to remove existing cracked or peeling finishes; wear protective equipment.
2. Sand the Surface
Sanding creates a surface profile for the paint to adhere to. Use 100-150 grit sandpaper on porcelain tubs. For fiberglass and acrylic, scuff sand using 220-400 grit.
3. Wipe Away Dust
Remove all dust left from sanding using a tack cloth. Ensure the surface is clean before priming or painting.
4. Apply Primer
Priming ensures better paint adhesion. Use a tub and tile primer meant for your tub’s material. Allow to fully dry per manufacturer directions before painting.
5. Paint the Tub
Apply at least two coats of tub and tile paint using a small paint roller and angled brush. Allow proper drying time between coats. Add additional coats for a smoother finish.
6. Let Cure
Allow paint to cure fully before adding caulk and using shower/tub – up to 2 weeks. Refer to paint directions for exact cure times.
Proper prep work and using paint formulated for tubs will provide long-lasting results. Consider hiring a professional if you are uncomfortable with any steps.
What Are Some Painting Tips for Bathtubs?
Here are some top tips to help you get great results painting a bathtub:
- Sand in multiple directions for better adhesion. Focus extra sanding on bottom of tub.
- Wipe surface thoroughly after sanding to remove every speck of dust.
- Inspect tub for any holes, cracks or flaws. Use filler/sealant on these areas before painting.
- Use satin, semi-gloss or gloss paint finishes. Avoid flat paints as they show water spots.
- Apply thin coats and allow proper drying time between coats as directed on paint.
- Use angled trim paintbrushes for cut-ins along edges and corners.
- Maintain wet edge and overlap strokes as you paint. Work top to bottom systematically.
- Remove drain stopper before painting. Use small brushes and cotton swabs for hard to reach areas near drain.
- Consider using painters tape around edges for a crisp paint line. Remove tape immediately after painting before paint dries.
- Allow paint to cure fully before exposing to moisture. Check paint directions for exact cure time.
- Be patient during drying and curing times for best durability. Rushing the process can ruin paint job.
Preparing the surface thoroughly and using the right tub paint will provide a durable and fresh look for your bathtub.
What Problems Can Occur Painting Bathtubs?
Painting a bathtub presents some challenges. Being aware of what could potentially go wrong can help avoid major issues down the line:
Poor Adhesion
Inadequate prep and surface profile can lead to peeling or chipping paint. Always sand and clean thoroughly before priming/painting.
Bubbling or Cracking
Applying paint too thick or over a glossy surface can cause bubbles under the paint. Acrylic tubs should be lightly sanded to remove gloss before painting.
Enamel Sags
Some enamel paints can sag on vertical surfaces. Maintain a wet edge and apply in thin, even coats allowing proper dry time between.
Blotchy Finish
Insufficient sanding and prep work or using the wrong roller can make the finish look uneven. Sand thoroughly and use recommended roller type.
Long Dry Times
Some paints require lengthy drying and curing periods before showering to maximize durability. Rushing the process can ruin paint. Follow directions.
Re-Painting Too Soon
Painting over existing tub paint before it has fully cured can cause poor adhesion and paint failure.
Doing appropriate preparation work, using compatible tub paints and allowing for proper curing times minimizes these potential issues for long lasting paint results. Consider hiring a pro if you’re unsure.
Can You Paint a Cast Iron Bathtub?
Painting cast iron bathtubs requires a different approach than ceramic, acrylic or fiberglass tubs. Here are some key considerations:
Challenging Surface
The bare iron surface is difficult for paints to properly adhere to. Special treatments and primers are required to help paint stick.
Prone to Rust
Cast iron tubs easily rust if the paint gets scratched or damaged, compromising paint adhesion. Avoid using abrasive cleaners.
Requires Specialty Paint
Use an enamel or epoxy paint specially made for cast iron. Latex and acrylic paints do not adequately protect the iron.
Professional Recommended
Painting cast iron tubs can be tricky for DIYers to get right. Consider hiring a professional refinisher.
Can you paint a cast iron bathtub?
While it is possible to paint a cast iron tub, the process is difficult for DIYers to do properly. Hiring a professional refinisher is often recommended for the best results on cast iron bathtubs.
What About Faux Finishing a Bathtub?
Beyond basic painting, faux finishing techniques can also be used to give a bathtub a unique, vintage or upscale look. Here’s an overview:
What is Faux Finishing?
Faux finishing refers to using paints and special application techniques to create an artificial finish that mimics materials like marble, stone, wood grain, etc.
Why Faux Finish a Tub?
It allows you to transform the look without replacing the tub. Traditional, vintage, natural stone or modern concrete looks can be achieved.
Tub Materials Compatible with Faux Finishes
Fiberglass, acrylic, porcelain and cast iron tubs can be faux finished. Proper prep and paints are required for adhesion.
Application Techniques Used
Sponging, ragging, stippling, color washing and using a specialty roller are some of the techniques used to create faux finishes.
Professional Skill Needed
Achieving the right look requires artistic skill. Consider hiring a professional faux finisher for the best results.
Faux finishing allows you to get very creative with the bathtub aesthetic. If done properly, it is a unique alternative to replacing the tub.
What About Refinishing a Tub Instead of Painting?
Rather than painting a bathtub, some homeowners opt to have it professionally refinished instead. Here’s how refinishing compares:
What is Bathtub Refinishing?
Refinishing involves spraying a new surface coating over the old tub surface using specialty bonding agents and acrylics.
Key Differences from Painting
Refinishing spray applies thicker than paint and bonds to form a new surface. Doesn’t require sanding or primer.
Who Should Refinish vs Paint?
Refinishing makes more sense for badly worn tubs. Painting works for tubs in good shape needing a refresh.
Duration to Complete
Refinishing can usually be done in a day. Painting requires more time for proper prep work and paint curing.
Cost Comparison
Professional refinishing costs $300-$1000 depending on tub size. DIY painting costs $50-$200.
Longevity
Refinish coatings last 5-10 years with care. Quality tub paint lasts 3-5 years before needing to be redone.
Refinishing can make sense for badly damaged tubs, while paint can provide a facelift for tubs in decent shape.
FAQs About Painting Bathtubs
