Painting plastic bathroom stalls can be a great way to cover up scuff marks, discolouration, and even graffiti. It can also be a cost-effective way to give your bathroom a new look. To paint plastic bathroom stalls, you'll need to start by cleaning the surface and removing any residue. Then, sand the surface to create a rough texture for better paint adherence. Next, apply a layer of primer and let it dry completely. Once dry, you can start painting, using either a paint sprayer or a roller. Allow adequate drying time between coats, and apply a second layer if needed. Finally, you can finish with a layer of acrylic topcoat to seal in the paint and add extra shine.

Preparation: Clean the surface with an ammonia-based cleaner and sand it with fine-grade sandpaper
Before painting plastic, it's important to prepare the surface. This involves cleaning, sanding, and priming the plastic to ensure the paint adheres properly and the final paint job looks professional.
First, clean the surface with an ammonia-based cleaner. You can use a regular bathroom cleaner and an abrasive sponge to give the plastic a deep clean. Make sure to get into any crevices or corners of the bathroom stall. If there are set-in stains, pour rubbing alcohol onto the stain and let it sit for 10 to 20 minutes before scrubbing it away. Then, rinse the surface with clean water and let it air dry completely.
Next, sand the surface with fine-grade sandpaper. Sanding the plastic will create a rougher, matte surface to which the paint can better adhere. It will also help remove any glossiness, which can interfere with the paint's ability to stick to the surface. Use a fine-grit sanding block or fine-grade wet/dry sandpaper to scuff the entire surface. Wipe down the surface with a clean, dry cloth to remove any dust or debris created by the sanding process.
After the surface is clean and sanded, it's important to apply a primer. Choose a primer that is suitable for the type of plastic you are painting and follow the manufacturer's instructions for application. Apply thin, even layers of primer and let it dry completely before proceeding to the painting stage.

Primer: Apply a layer of latex primer using a paint sprayer or roller
To paint plastic bathroom stalls, you'll need to prime the surface before painting. Here's a detailed guide on applying a layer of latex primer using a paint sprayer or roller:
Before you begin priming, ensure the surface is clean and prepared. This includes removing any existing paint, dirt, or residue. Use a cleaner suitable for the surface, such as an ammonia-based cleaner for laminate partitions, and scrub the surface thoroughly. Grime and dirt can interfere with the paint and cause it to peel and chip over time. Once the surface is clean, lightly sand it with sandpaper to create a rough texture that will help the primer adhere better. For laminate surfaces, you can use medium-grit sandpaper, while for metal surfaces, fine-grade wet/dry sandpaper is recommended. Remember to wipe away any sanding residue and ensure the surface is completely dry before proceeding.
When you're ready to prime, equip yourself with either a paint sprayer or a roller fitted with a low-nap roller cover. Apply the latex primer in rows, using two to three thin, overlapping layers to build up an even coat. This technique helps ensure complete coverage and a smooth finish. Wait for about two hours between each layer to allow the primer to dry slightly. After applying the final layer, let the primer cure for approximately two days.
Once the primer has cured, lightly sand it again with fine-grit sandpaper, such as 220-grit. This step helps smooth out any imperfections and ensures a uniform surface. Remove any buildup or lines left by the roller with the sandpaper. Finally, wipe the panels with a clean cloth to remove any residue from the sanding process. Now, your plastic bathroom stalls are ready for the paint application, which you can apply using the same technique as the primer. Remember to follow the manufacturer's instructions for drying time and ventilation during the priming and painting process.

Painting: Use interior latex paint with a bit of gloss
Painting plastic bathroom stalls can be a great way to cover up old stains and give your bathroom a new look. Here are some detailed instructions on how to paint plastic bathroom stalls using interior latex paint with a bit of gloss:
Preparation:
Start by giving your bathroom stall a deep clean using your usual bathroom cleaner and an abrasive sponge. Remove any soap, oil, glue, or foreign residue with an appropriate solvent. This step is crucial as it ensures that the surface is ready for painting. Next, sand the entire surface with fine-grade wet/dry sandpaper to create a rough texture that the paint can adhere to. Wipe down the surface with a damp cloth to remove any dust or grit and ensure it is completely dry before proceeding.
Priming:
Before painting, it is recommended to apply a primer to create a smooth base for the paint to adhere to. Choose a mildew-resistant or mould-killing primer, especially if your bathroom has poor air circulation or lacks windows. Follow the manufacturer's instructions and allow the primer to dry completely before proceeding to the next step.
Painting:
Use a small roller or a spray bottle to apply your chosen interior latex paint with a bit of gloss. Apply the paint in thin, even layers to ensure a smooth and streak-free finish. Allow adequate drying time between coats, following the instructions on your paint can. Apply a second coat if necessary.
Finishing:
Once you are happy with the coverage and the paint is completely dry, you can finish with a layer of acrylic topcoat. This will seal in your paint, add extra shine, and provide a protective layer. Again, allow the appropriate drying time for the topcoat.
By following these steps and allowing adequate drying time between each step, you can transform your plastic bathroom stalls and give them a brand-new lease of life.

Topcoat: Apply a coat of polyurethane for extra protection
To paint plastic bathroom stalls, you must first prime the plastic surface to create a textured undercoat for the topcoat to stick to. Since plastic is non-porous and slick, a sealer won't adhere well without a primer. Paint primers are formulated with extra bonding additives that help them adhere to different surfaces, including slick plastic.
Once the primer is dry, you can apply the polyurethane topcoat. Polyurethane is a synthetic resin used to protect and enhance the appearance of surfaces. It works by forming a hard, protective coating that is resistant to scratches, stains, and moisture. The two basic types of polyurethane are oil-based and water-based, and both have different pros and cons. Water-based polyurethane is clear, has a low odour, and dries quickly, but it may require more coats. Oil-based polyurethane is more durable, withstands heat better, and is ideal for surfaces that are exposed to the elements. For outdoor plastic surfaces, use exterior polyurethane as it is formulated with UV-blockers and will protect the surface from outdoor weather elements.
You can apply polyurethane with a brush, rag, or spray. Brushes are best for flat surfaces, while rags or cloths are ideal for contoured surfaces. An aerosol spray is good for hard-to-reach areas or intricate designs. When applying, use a clean microfiber towel and follow the grain of the surface. Apply each coat with the grain, and make sure to sand between coats to remove any drips, bubbles, or other uneven spots. For optimal protection, apply at least three coats, allowing each coat to dry thoroughly before the next.

Drying: Allow adequate drying time between coats and before use
Drying time is an important consideration when painting plastic bathroom stalls. Inadequate drying time can lead to an unattractive finish, with the paint peeling or chipping over time. Therefore, it is crucial to allow sufficient drying time between each coat of paint and before using the painted surface.
When painting plastic bathroom stalls, it is recommended to apply multiple thin coats of paint rather than one thick coat. This technique results in a more durable finish. After applying each thin coat of paint, allow adequate drying time according to the manufacturer's instructions. The drying time can vary depending on the type of paint used and the environmental conditions, such as temperature and humidity.
For example, when painting laminate bathroom partitions, it is common to use a latex paint. After applying each coat of latex paint, it is recommended to wait at least two hours for the paint to dry before applying the next coat. This waiting period ensures that the paint has had sufficient time to cure and harden.
Additionally, it is essential to consider the drying time of any primer or bonding agent used before painting. For instance, when applying a layer of super adherent latex primer to plastic laminate walls, it is recommended to wait two hours between each layer and two days after the final layer to ensure proper curing.
Once you have finished painting and applied the final coat, allow ample drying time before using the bathroom stalls. This period can vary depending on the type of paint and the environmental conditions. In the case of laminate partitions, it is recommended to let the paint cure for five to seven days before heavy use.
