Can You Spray Paint A Fiberglass Bathtub?

If you really want to change the way your fiberglass bathtub looks but don't have the money to hire a professional, you can still paint it on your own. However, you need to consider other epoxy refinishing kit application methods like traditional brush or roller brush and use one quart kit  of epoxy refinishing kit instead.

Spray paint works just fine on an acrylic bathtub. You need to use acrylic polymer paint for this type of surface to ensure that it will be coated properly with multiple coats. 

You also need to put a primer on before spraying paint to seal the smooth surface and smoothen different blemishes. An acrylic bathtub is probably the easiest type of bathtub to spray paint on.

  • Painter’s tape 
  • Sandpaper 
  • Cloth 
  • Spray primer 
  • Spray paint 
  • Paper towels 
  • Silicone caulk (if you will remove the bathtub fixtures) 
  • Trash bags (if you’re not going to remove the fixtures) 
  • Mask 
  • Optional: Epoxy putty 
  • Optional: Acetone 

Step By Step Instructions 

It is important to use the recommended tools and materials and to follow the manufacturer's instructions carefully to ensure the best possible results.

  • 1
    The first and most important thing you need to do before painting your tub is to clean it thoroughly. Don’t just wash it over. You need to remove the grime and any other stain you see on it. If you don’t, the paint won’t attach properly to the surface, and the output will not be visually pleasing. To do this, diluted bleach to remove mold from it.
  • 2
    If there’s grime on it, use a soap scum remover Open the windows and run the bathroom exhaust fan before you begin to clean up any grime, soap scum, and mildew. For oily or waxy stains, use acetone. For small mistakes like drips or runs in the paint, you can use a razor blade to remove them carefully.
  • 3
    Make sure to rinse the cleaners if you are using more than one of them. You also need to scrub it thoroughly with a brush to ensure everything is clean.  
  • 4
    After thoroughly rinsing, wipe a solvent such as acetone (paint thinner would work here, too) over the entire surface to remove any remaining grease or cleanser residue.
  • 5
    If there are any large cracks or scratches, fill them with epoxy putty. Don’t worry if it doesn’t match the tub. You’ll paint over it anyway. The most important thing is to fix the scratch and cracks before it becomes a significant problem. Once the epoxy putty is cured, sand it.
  • 6
    Next, remove the bathtub’s fixtures if you can. It will make it easier to spray paint the tub without them. Otherwise, use a trash bag and painters tape to cover them.
  • 7
    After that, protect the surrounding area with more trash bags and painter’s tape. You want to cover everything you can as much as possible to ensure that the paint won’t get through them.
  • 8
    Once you’ve protected the surrounding area, lightly sand the entire tub with sandpaper. This ensures that the paint will stick. Then, remove the dust with a cloth.
  • 9
    Next, ensure that the tub is completely dry. Then, wear your protective mask and start the painting process. First, you need to spray it with the primer. This will make the paint last longer. Wait for the primer to dry. It’s best to let it cure for 24 hours before painting over it. 
  • 10
    After 24 hours, spray paint the tub. This won’t be an easy process, and once you start spray painting, you shouldn’t stop until you are finished with everything. Ensure that you have enough bottles of spray paint, or your whole effort will go to waste. The spray coats usually dry within 10 minutes, and you won’t be able to spray paint over it after 6 hours, so you have to work quickly. It’s best to have someone help you throughout the whole process to ensure a seamless spray painting session. 
  • 11
    Once you’re done, let it dry for at least 24 hours. Then, reinstall the fixtures; if you’ve removed them, then you’re all set. You now have a newly painted tub.  

Why Use Spray Paint On Bathtubs?

The convenience of spray paints is nothing new. Everyone is familiar with how easy it is to use compared to other types of paint.

So, it’s natural for many people to choose them over other paint types. However, spray paint isn’t always the best choice when it comes to paint a bathtub. Spray paints can’t be used on some tub surfaces like fiberglass.  

At the same time, you need to act quickly when spray painting a tub. It requires you to finish the coating in a specific amount of time, or else it won’t give you the output you’re looking for. Only commit to this type of paint if you have the time and money, as it will require a lot of spray paint bottles to finish a whole tub.  

While spray paint is a convenient choice, it's still best to weigh out all your options before committing to this painting method right away. Some other surfaces are better with other types of paint, even if you can use spray paint on them.

It’s best to do more in-depth research on the kind of surface your bathtub has and what paint is better on it.  


Important Tips To Know

Before spray painting your bathtub, make sure you wear a protective mask, as the smell can be intoxicating. If there are windows in your bathroom, open them to let the smell out and create as much ventilation as possible. 

You can also use a special mask for odor if you can't tolerate the smell of the paint. Wear gloves as well to keep your hand from getting painted.  

Another thing that you should not miss when painting a tub is the cleaning process. While it’s easier to skip this part, it will ruin the whole paint job. That’s why you need to scrub your tub clean and remove any dirt and grime you can find.  

Additionally, always sand your tub before painting it. This allows the paint to stick better to the bathtub and keeps the paint longer. Don’t forget to seal cracks and scratches, as it will help preserve your bathtub longer.
