Plastic laundry tubs are durable and long-lasting, but they can become stained and scuffed over time. While some opt to replace their tubs, there are ways to rejuvenate them. This can be done by cleaning the tub with inexpensive household products, such as vinegar, baking soda, lemon juice, or specialised cleaning products. For more extensive damage, such as holes or cracks, the tub can be repaired with a fibreglass repair kit or Bondo, and then refinished with paint to achieve a professional, long-lasting result.

What You'll Learn

Clean with vinegar, baking soda, or lemon juice
To rejuvenate a plastic laundry tub, a simple and inexpensive way is to use vinegar, baking soda, or lemon juice. These household products can effectively remove tough stains and disinfect the tub.
For vinegar, combine a 1:4 ratio of vinegar to water in a spray bottle. Spray the entire tub with the mixture and use a soft-bristle brush to gently scrub the tub. For more stubborn stains, add baking soda to the mix, which will create a fizzy cleaning solution. Alternatively, create a baking soda paste by combining three parts baking soda with one part water and apply it to the stain.
Lemon juice can also be used to rejuvenate the tub. Squeeze fresh lemon juice onto tough stains and use a soft-bristle brush to scrub the stain. Lemon juice will bleach the stains and disinfect the tub.
For extra tough stains, a combination of these products can be used. For example, sprinkle baking soda on the tub and then spray vinegar on top, creating a fizzy reaction that can help to break down tough stains.
These natural cleaning solutions are not only effective but also environmentally friendly and cost-effective, as they utilize inexpensive household products.

Sand down to remove cracks and scuffs
Sanding down the cracks and scuffs on a plastic laundry tub can help restore its appearance and prevent further damage. Here is a step-by-step guide to the process:
Identify the Areas to be Repaired
Begin by thoroughly inspecting the tub to identify all the cracks, scuffs, and abrasions that need to be addressed. Mark these areas with painter's tape, especially if there are multiple spots that require attention. This will help you target your sanding efforts effectively.
Prepare the Surface
Before you start sanding, it's crucial to prepare the surface by cleaning it. Use a vacuum cleaner to remove any dust, debris, or residue from the tub. Alternatively, you can wipe down the surface with a damp cloth or paper towel. If you opt for the damp cloth method, ensure you allow sufficient drying time—approximately 15 minutes—before proceeding to the next step.
Sand the Surface
Once the surface is clean and dry, you can begin sanding. Using fine-grit sandpaper, lightly sand the cracks and the surrounding areas. Take care not to apply too much pressure, as you don't want to create new scratches or damage the tub further. Sand in smooth, even strokes, blending the edges of the repair area with the surrounding surface. This process will help create a seamless transition between the repaired and original surfaces.
Switch Sandpaper Grits
After sanding with the initial grit, you can switch to a finer-grit sandpaper for a smoother finish. Gradually increase the grit size as you repeat the sanding process. This will help you achieve a more refined and polished surface. Take your time with each grit, ensuring that you remove any imperfections left by the previous grit.
Finish with a Clean-up
As you sand, periodically clean the surface to remove any sanding debris. This will help you assess your progress and ensure that you're achieving the desired smoothness. After each sanding pass, use a soft cloth or vacuum cleaner to wipe away the dust. A clean surface will also help you identify any areas that might need additional attention.
By following these steps and taking a methodical approach to sanding, you can effectively remove cracks and scuffs from your plastic laundry tub, leaving it with a smooth and refreshed appearance.

Apply a bonding agent
Before applying a bonding agent to your plastic laundry tub, it is important to prepare the surface. Start by cleaning the tub with a sponge and a bath cleaning product to remove any grease or grime. Then, use fine sandpaper to sand down the tub, evening out any cracks or scuffs. Sanding will also roughen the surface, providing a better grip for the bonding agent. After sanding, wipe down the tub to remove any residue and then let it dry thoroughly. It is important to ensure that the tub is completely dry before applying the bonding agent, as any remaining moisture can affect adhesion.
Once the tub is clean, dry, and free of residue, you can apply the bonding agent. Choose a bonding agent specifically designed for use on plastic surfaces. Follow the instructions on the product you have selected for the correct application method and safety precautions. Typically, you will apply the bonding agent in an even layer over the entire surface of the tub. This will prime the tub, ensuring proper adhesion for the new finish and creating a smoother surface for your paint.
When applying the bonding agent, work in a well-ventilated area and wear gloves and a face mask to protect yourself from any fumes. Use a brush or roller designed for use with the bonding agent, or a spray bottle if it is sold in a spray format. Ensure you have protected the surrounding area, including the floor and any areas of the tub you do not want to paint, with drop cloths and construction tape. This will help you achieve a clean, professional finish.
After applying the bonding agent, allow it to dry completely according to the manufacturer's instructions. This step is crucial, as it ensures the bonding agent is fully cured and ready for the new finish. Once the bonding agent is dry, you can move on to the next step of refinishing your plastic laundry tub, which may include painting or applying a new surface coating.
By following these steps and applying a bonding agent, you will create a strong foundation for your new finish, helping it adhere properly and ensuring a durable and long-lasting rejuvenation of your plastic laundry tub.

Paint the tub
Painting your plastic laundry tub can be a cost-effective way to upgrade its appearance. Before you start, make sure you have all the necessary materials and that the tub is made from a material that can be painted.
There are two main ways to paint a plastic laundry tub: with spray paint or brush-on paint. Spray paint is quicker and easier to apply, but it can be messier. Krylon Fusion for Plastic and Rust-Oleum Paint for Plastic are both spray paints that stick to most hard plastics, including acrylic, polypropylene, and fiberglass composite. They are only sold in spray cans, so dealing with overspray is critical. Be sure to cover any surfaces other than the sink where paint droplets might land, such as walls, floors, cabinets, and the faucet. Wear a mask and goggles for protection.
Brush-on paint is a less messy alternative. Rust-Oleum Specialty Plastic Primer is a brush-on paint that bonds to plastic, allowing you to use standard paint as a topcoat. You can choose the colour of your choice for the topcoat. However, brush-on paint may require more preparation time, as you will need to cover the floor and surrounding areas to avoid any drips or spills.
Regardless of the painting method you choose, it is important to clean and prepare the surface of the tub before painting to ensure the best results. Make sure the tub is free of any dirt, debris, or stains that may interfere with the paint adhesion. Once you have painted the tub, consider applying a clear coat to seal and preserve the paint.

Finish with a polyurethane topcoat
To finish with a polyurethane topcoat, you must first prepare the surface of your plastic laundry tub. Start by thoroughly cleaning the tub with a vinegar and water solution, or a mild disinfectant like lemon juice. For tough stains, create a baking soda paste, or try a home remedy involving aluminium foil, silverware, salt, baking soda, and boiling water.
Once the tub is clean, sand down the surface to make it smooth and even. Patch up any holes or irregularities with a repair kit, epoxy, or Bondo. Vacuum and wipe down the tub to ensure it is completely free of dust and dirt particles.
Next, apply a bonding agent to increase the adhesion of the topcoat. You can use a primer with epoxy properties or a special type of glue. The primer will also help to cover any small irregularities and create a solid background colour. After the bonding agent has been applied, you can spray or brush on the polyurethane topcoat.
Polyurethane is a popular topcoat choice for plastic tubs as it provides a high level of resistance to humidity, soaps, shampoos, and other chemicals. It will also add a glossy finish to your tub, giving it a brand-new look. Make sure to follow the manufacturer's instructions and allow the tub to dry completely before using it.
