Painting a plastic tub can be a great way to cover up old staining and give your bathroom a new look. However, it can be tricky because plastic is smooth and non-porous, so most paints won't adhere to it. The best material for the job is acrylic enamel, which can be purchased in a typical tub or spray bottle. If you use a tub of paint, a small roller will help you achieve an even and streak-free finish. You'll also need a specific bonding agent to use as a primer, which will smooth out the surface of your tub and allow your paint to adhere better. To prepare your tub for painting, you should first clean it with an abrasive sponge and then sand it with fine sandpaper to give the paint something to grip onto.

What You'll Learn
Sand the tub to create a texture for the paint to grip on to
Painting a plastic tub can be challenging because plastic is smooth and non-porous, so most paints won't adhere to it. To overcome this, you can sand the tub to create a texture for the paint to grip onto. This process will give the plastic tub a roughed-up surface that paint can stick to.
Before you start sanding, it's important to clean the tub thoroughly to remove any dirt, soap scum, or other contaminants. This will ensure that the sanded surface is free of any impurities that could interfere with the painting process.
When sanding the tub, use fine-grit sandpaper or a power sander to create a uniform texture across the entire surface. Sand in the direction of the grain, if there is one, to achieve a consistent finish. Pay extra attention to any areas that are particularly smooth or shiny, as these may require more sanding to create a texture that paint can adhere to.
It's important to note that you should not use outdoor sand, as it can contain impurities that will negatively impact the paint and leave a clumpy mess. Instead, opt for fine sand, such as play sand, which is clean and coarse enough to provide a good texture for the paint to grip onto.
After sanding, be sure to remove any dust or debris from the surface with a tack cloth or a damp cloth. Once the surface is clean and dry, you can start the painting process, following the instructions on your chosen paint for the best results.

Apply paint with a roller for an even, streak-free finish
Painting a plastic tub can be a great way to cover up old stains or discolouration, and give your bathroom a new look. However, because plastic is smooth and non-porous, most paints won't adhere to it. Therefore, it is important to prepare the surface properly and use the right type of paint to ensure a successful paint job.
To achieve an even and streak-free finish, it is recommended to use a small roller instead of a brush. Acrylic enamel paint is the best material for the job, and it can be purchased in a tub or a spray bottle. If you opt for a tub of paint, make sure to use a roller with a smooth, even surface to avoid creating texture on the painted surface.
Before you begin painting, it is important to clean the tub thoroughly and sand it with fine sandpaper to create a rough surface for the paint to grip onto. Wipe down the tub to remove any traces of grit and ensure it is completely dry.
When you are ready to paint, use a roller with a smooth, even surface to apply the paint in thin, even layers. Take your time to ensure that you are getting an even coverage across the entire surface of the tub. Allow adequate drying time between coats, following the instructions on your paint container. You may need to apply multiple layers to achieve the desired coverage and finish.
Finally, you can seal in your paint and add extra shine by applying a layer of acrylic top coat. This will help protect your paint job and ensure its longevity. Make sure to follow the instructions on your paint and top coat containers for proper application and drying times.

Seal the paint with a top coat to add shine and durability
Sealing your paint with a top coat will not only add shine and durability but will also protect your paint job from the elements. If your plastic item will be spending time outdoors or will experience heavy use, consider protecting it with a clear acrylic sealer. Sealers are available in a glossy or matte finish, so you can choose the look you desire.
Before applying your top coat, ensure that the final layer of paint has had plenty of time to cure. This will ensure that your paint job is dry and ready for the next step. When you are ready, spray on the sealer using smooth, overlapping strokes, just as you would with the paint. It is recommended to apply at least two or three coats of the sealer, allowing 30 minutes of drying time between each coat. After the final coat, wait 24 hours before handling the object to ensure the surface is fully dry and set.
The type of sealant you use is important. You can use a mod podge acrylic sealer spray, an acrylic-based lacquer, or a clear sealant spray. However, do not use anything with oils, as this will ruin the acrylic paint. You can also use a polyacrylate resin sealant, which gives the clearest finish compared to other sealants. This type of sealant is also water-resistant, making it a good choice for outdoor items. If you are using multiple colours, you may want to consider using masking tape to create a border and avoid any unnecessary colours coming through.
Additionally, you can prepare the plastic surface by lightly sanding it with 120 to 220 grit sandpaper. This will help to level the surface and improve the adhesion of the sealant and paint. After sanding, use a blower, vacuum cleaner, or a cloth to remove any dust. You can then apply a primer coat to help cover any complex details of the surface, giving it a clean result.

Wear protective gear, including a face mask and gloves, to ensure safety
Painting a plastic tub requires specific materials and safety precautions. Before starting, it is crucial to wear protective gear to ensure your safety. This includes a face mask and gloves, which are essential for protecting your skin and respiratory system from paint fumes and particles.
The painting process can generate paint dust, which can irritate your respiratory system if inhaled. Therefore, wearing a face mask is vital to safeguarding your health. Choose a well-fitting mask that covers your nose and mouth securely. This will prevent the inhalation of paint dust and provide an effective barrier.
Gloves are another critical component of your protective gear. They act as a protective barrier for your skin, shielding it from direct contact with the paint. Paint can contain chemicals that may irritate or harm your skin, so gloves are necessary to minimize this risk. Opt for gloves made from durable materials that fit snugly and allow for a full range of motion.
In addition to the face mask and gloves, you can also consider wearing protective eyewear to shield your eyes from paint splatters. Paint can sometimes drip or splatter, and protective eyewear will provide an extra layer of defense for your eyes. It is also advisable to wear old clothing or an apron to prevent paint stains on your clothes.
Before beginning the painting process, ensure you have laid out drop cloths, newspapers, or plastic sheets to catch any paint drips or spills. Covering your work area adequately will help minimize the risk of slipping on wet paint and protect your floor from damage.
By taking these precautionary measures and wearing the appropriate protective gear, you can ensure your safety and well-being while painting plastic tubs. It is always better to be cautious and protect yourself adequately, even if it may seem like overpreparation.
