Reglazing Your Plastic Tub: A Step-By-Step Guide

how to reglaze a plastic tub

Reglazing a plastic tub can be a great way to give your bathroom a fresh look without breaking the bank. Bathtub reglazing is a subset of the bathtub refinishing process, which involves refurbishing the surface of a bathtub with a coating. This can be done using a DIY kit, which typically includes epoxy resin, etching powder, gloves, safety goggles, and other materials. The process involves cleaning and sanding the tub, repairing any chips or cracks, and then applying the new coating. While DIY tub reglazing can be a cost-effective option, hiring a professional refinisher can result in a more durable and long-lasting finish.

Reglazing vs. refinishing

Reglazing and refinishing are terms used to describe the process of restoring a bathtub to make it look new again. Although the terms are often used interchangeably, they refer to different parts of the restoration process.

Refinishing typically refers to the entire process of restoring a tub, including repairs, resurfacing, and reglazing. It involves cleaning the tub, repairing any damage, such as chips, cracks, or scratches, and then applying a new coating. Refinishing can be done using a DIY kit or by hiring a professional refinisher. The DIY kits include epoxy resin with hardener, etching powder, latex gloves, steel wool, brush, cleaning solution, cleaner or thinner, and safety goggles. The main steps for refinishing with a kit include cleaning, sanding, and coating the tub.

Reglazing, on the other hand, refers specifically to the final step of the refinishing process, which is the application of the new coating or finish. It involves preparing the tub by cleaning and repairing any damage, similar to the refinishing process. Then, a chemical or acidic solution is used to etch the tub's surface, followed by the application of a high-gloss finish that is sprayed onto the surface.

The lifespan of a reglazed bathtub is typically five to ten years or longer, depending on use, care, and maintenance. Reglazing is a cost-effective way to restore the bathtub's appearance and can be done for as little as $350, compared to the average cost of replacing a bathtub, which is $2,000.

Overall, whether you choose to refer to the process as reglazing or refinishing, the goal is to transform your old tub from chipped, dirty, and faded to bright, glossy, and new-looking.

Preparing the tub

Reglazing your plastic tub can be a great way to give your bathroom a fresh look without the expense of a full renovation. The process is relatively straightforward, but it's important to take the necessary precautions and prepare the tub properly for the best results. Here's a step-by-step guide to preparing your plastic tub for reglazing:

Cleaning the Tub

First, ensure your tub is as clean as possible. Use a sponge and a bath cleaning product to remove any traces of grease, grime, mildew stains, and scuff marks. Bleach can be effective for tackling tough stains. This step is crucial as it ensures that the new finish will adhere properly to the surface.

Sanding the Surface

Once the tub is clean and dry, use fine sandpaper (#400 or #600) or a finish sander to sand down the surface. This process helps to roughen the surface, creating a better grip for the new finish. It also helps to even out any larger cracks or scuffs. After sanding, wipe down the tub with a tack cloth to remove any dust or residue.

Filling Chips and Dings

Inspect the tub for any chips or dings. Use epoxy putty, which is often included in reglazing kits, to fill and patch these areas. Allow the patches to dry completely before proceeding to the next step.

Applying a Bonding Agent

To ensure proper adhesion and a smooth surface for painting, apply a specific bonding agent or primer to the tub. This step is crucial in achieving a professional-looking finish. Follow the instructions on the product you are using for proper application techniques and drying times.

Ventilation and Protection

Before you begin the reglazing process, ensure your work area is well-ventilated by opening windows or setting up fans. Also, protect the surrounding areas of your bathroom by laying drop cloths or floor coverings and using painter's tape along the edges of the tub and any areas you don't want to paint.

Choosing the Right Paint

Select the appropriate paint for the job. Acrylic enamel is recommended for refinishing plastic tubs and can be applied using a spray bottle or a traditional paint can. Spraying may result in a more even finish but can be more expensive and prone to accidents.

With these steps completed, your plastic tub is now prepared for reglazing. Remember to take your time, work in a well-ventilated area, and follow the instructions on your chosen products for the best results.

Safety precautions

Reglazing a plastic tub is a cost-effective way to restore your tub to its former glory. However, it is important to take specific safety precautions to ensure the job is done safely and effectively. Here are some essential safety precautions to keep in mind:

  • Ventilation: Proper ventilation is crucial to minimize the inhalation of dangerous chemicals such as carbon monoxide and methylene chloride. Open windows and doors in the bathroom, and use fans to remove fumes from the room.
  • Protective Gear: Always wear protective clothing and use safety-rated equipment when reglazing a bathtub. This includes gloves, safety goggles, and a respirator mask.
  • Surface Coverage: Cover nearby surfaces with drop cloths or plastic sheeting to protect them from overspray or spills.
  • Seal Vents: Seal off any HVAC vents in the bathroom to prevent fumes from spreading to other parts of the house.
  • Dispose of Materials Responsibly: Follow local regulations and guidelines for disposing of chemical products and materials. Ensure that all containers holding chemicals are sealed tightly before disposal. Do not pour leftover chemicals down the drain as they can be harmful to the environment and the water supply.
  • Curing Time: Allow the reglazed surface to cure for at least 24-48 hours before using the tub. Inspect the surface for any chips or cracks that could expose you to underlying chemicals.
  • Maintenance: Avoid using harsh cleaning chemicals or abrasive tools on the reglazed surface to prevent damage. Regularly inspect and maintain safety features such as non-slip mats or decals inside and outside the bathtub to prevent slips and falls.

Applying the glaze

Before applying the glaze, ensure that your tub is as clean as possible. Use a sponge and a bath cleaning product to remove any traces of grease or grime. You can use bleach to clean mildew stains, then scrub the entire tub with an abrasive cleanser or a product like Lime-A-Way applied with an abrasive pad. Rinse with clear water.

Once your tub is clean, you can begin the reglazing process. If you are using a DIY kit, refer to the manufacturer's instructions for application methods and safety information. Most kits include epoxy resin with a hardener, etching powder, latex gloves, steel wool, a brush, cleaning solution, a cleaner or thinner, and safety goggles.

Apply an even layer of paint to the entire tub. You can use a brush or roller, or for a more even finish, try spraying the paint on. Allow the paint to dry, then assess whether a second coat is needed.

After you are happy with the coverage, finish with a polyurethane topcoat. This will help ensure your bathtub is more durable and keep your paint colour looking fresher for longer.

The lifespan of a reglazed bathtub is typically five to ten years, or possibly longer, depending on use, care, and maintenance.

Drying and finishing

After sanding, it is important to wipe down your tub to remove any traces of the sanded surface. Then, dry the tub thoroughly and allow extra time for the moisture to evaporate. Any water left in the tub could prevent the new finish from adhering properly.

The final stage of prep work is applying a specific bonding agent to prime your tub. This will ensure proper adhesion with your new finish and give a smoother surface to help your paint look more even.

Now, you can apply an even layer of paint to the entirety of your plastic tub and leave it to dry. Once it has dried, you can see whether it may benefit from a second layer. Once you're happy with the coverage, finish with a polyurethane topcoat. This will help ensure your bathtub is more durable and keep your paint colour looking fresher for longer.

Remember, your bathtub will be out of commission for at least three days while the new finish cures.
