How Do You Paint A Fiberglass Bathtub?

Fiberglass bathtubs are a popular choice for bathrooms because they are durable, easy to clean, and affordable. However, over time, the finish on a fiberglass bathtub can start to fade or chip. If this happens, you can easily give your bathtub a new look by painting it.

This guide will show you how to paint a fiberglass bathtub in three simple steps:

1. Preparation
2. Painting
3. Finishing

Preparation

The first step to painting a fiberglass bathtub is to prepare the surface. This involves cleaning the bathtub, removing any old paint, and applying a primer.

Clean the bathtub. To clean the bathtub, start by removing all of the fixtures, such as the drain, faucet, and showerhead. Then, use a mild detergent and warm water to clean the bathtub. Be sure to rinse the bathtub thoroughly to remove all of the soap.

Remove old paint. If the bathtub is already painted, you will need to remove the old paint before you can apply new paint. You can do this by using a chemical stripper or a heat gun. If you use a chemical stripper, be sure to follow the directions on the product label. If you use a heat gun, be sure to wear gloves and eye protection.

Apply a primer. Once the bathtub is clean and free of old paint, you will need to apply a primer. Primer helps to create a smooth, even surface for the paint to adhere to. You can use a primer specifically designed for fiberglass bathtubs, or you can use a general-purpose primer.

Painting

The next step is to paint the bathtub. You will need to apply two coats of paint, allowing the first coat to dry completely before applying the second coat.

Apply the first coat of paint. To apply the first coat of paint, use a paintbrush or roller to apply the paint evenly to the bathtub. Be sure to work in small sections, and overlap each stroke slightly. Allow the first coat of paint to dry completely before moving on to the next step.

Apply the second coat of paint. Once the first coat of paint is dry, you can apply the second coat. Apply the second coat of paint in the same way as the first coat, allowing it to dry completely before using the bathtub.

Finishing

The final step is to finish the bathtub. This involves applying a sealant to the paint to protect it from water damage. You can use a sealant specifically designed for fiberglass bathtubs, or you can use a general-purpose sealant.

Apply the sealant. To apply the sealant, use a paintbrush or roller to apply the sealant evenly to the bathtub. Be sure to work in small sections, and overlap each stroke slightly. Allow the sealant to dry completely before using the bathtub.

Painting a fiberglass bathtub is a relatively simple project that can be completed in a few hours. By following these steps, you can give your bathtub a new look that will last for years to come.

Here are some additional tips for painting a fiberglass bathtub:

  • Use a good quality paint that is specifically designed for fiberglass bathtubs.
  • Apply the paint in thin coats, allowing each coat to dry completely before applying the next coat.
  • Be careful not to apply too much paint, as this can cause the paint to run.
  • Allow the paint to dry completely before using the bathtub.

By following these tips, you can ensure that your fiberglass bathtub looks its best for years to come.

Preparing the Bathtub

Before you can paint a fiberglass bathtub, you need to prepare the surface. This involves cleaning the tub, removing any old paint, and applying a primer.

Cleaning the Tub

The first step is to clean the bathtub thoroughly. This will remove any dirt, grease, or soap scum that could interfere with the paint adhesion. You can use a mild detergent and a sponge or a brush to clean the tub. Be sure to rinse the tub thoroughly afterwards.

Removing Old Paint

If the bathtub is already painted, you will need to remove the old paint before you can apply new paint. You can do this by using a chemical stripper or by sanding the tub. If you use a chemical stripper, be sure to follow the directions on the product label. If you sand the tub, be sure to wear a dust mask and eye protection.

Applying a Primer

Once the tub is clean and free of old paint, you need to apply a primer. The primer will help the paint adhere to the surface of the tub and prevent the paint from chipping or peeling. You can use a primer specifically designed for fiberglass bathtubs, or you can use a general-purpose primer.

Applying the Paint

Once the primer is dry, you can apply the paint. You can use a brush or a roller to apply the paint. Be sure to apply the paint in thin coats, and allow each coat to dry completely before applying the next coat.
