What You'll Learn
Choosing the right paint
When it comes to choosing the right paint for your plastic RV sink, there are a few things to consider. Firstly, it is important to select a paint that is specifically designed for plastic surfaces. These paints are formulated to adhere better to plastic than regular paints, ensuring a longer-lasting finish. You can find plastic-specific spray or canned paint options at your local hardware store or online.
One popular option recommended by many RV enthusiasts is Krylon plastic paint, which can be found at hardware stores. Another option that has worked for some is Rustoleum bathtub-sink paint, which can also be used on plastic sinks. If you are painting an acrylic sink, you may need to use a specific type of paint designed for acrylic surfaces, such as appliance paint for fridges and cookers.
Before applying any paint, it is crucial to properly prepare the surface. Clean the sink thoroughly with warm water, dish soap, and a scouring sponge to remove any grease, grime, or residue. Once the sink is clean and dry, apply rubbing alcohol to the entire surface and let it dry. This will help the paint adhere better. Next, use 100 or 150-grit sandpaper to sand down the surfaces until the shiny top layer of the plastic is removed. Be careful not to press too hard and scratch the surface. Wipe away the dust with a damp cloth, then use painter's tape to block off any areas you don't want to paint.
When you are ready to paint, always test the paint on a piece of cardboard or newspaper first. If using a spray paint, hold the can at least 12-15 inches away from the surface and apply light, even coats. Let each coat dry before applying the next, and aim for 2-3 layers for the best coverage. If using a brush, dip your brush into the paint and apply light, even strokes, being careful to avoid leaving brushstrokes on the finished surface. Again, thin coats are better to create a smoother finish and avoid drips.

Preparing the sink
Start by thoroughly cleaning the sink to remove any dirt, grime, or residue. Use a mild cleaner and avoid abrasive cleaning products or sponges, which can scratch the surface. Once the sink is clean, dry it completely.
Next, you will need to repair any cracks or damage to the sink. If your sink is cracked, fill in the cracks with an appropriate filler or putty. Sand the sink to create a smooth surface for the paint to adhere to. This step is important, as it will help the paint go on smoothly and create a more durable finish.
After sanding, wipe down the sink again to remove any dust or debris. Use a damp cloth to ensure you get rid of all the sanding residue. It is crucial to have a clean surface before painting.
Before you begin painting, it is essential to choose the right paint for the job. Select a paint specifically designed for use on plastic surfaces, such as Krylon plastic paint or a similar product. Ensure you read and follow the instructions on the paint can for the best results.
Once you have the paint, remember to constantly shake and turn the can to prevent any drips. It is recommended to apply several thin coats of paint rather than one thick coat for a more even and durable finish.
By following these steps, you will effectively prepare your plastic RV sink for painting and achieve a long-lasting and attractive result.

Painting the sink
Prepare the sink:
Start by thoroughly cleaning the sink to remove any dirt, grime, or residue. This will help the paint adhere better to the surface. You can use a mild detergent and a soft cloth or sponge for this step, but avoid abrasive cleaning products or pads, as they may scratch the plastic. Ensure the sink is completely dry before moving on to the next step.
Choose the right paint:
Select a paint specifically designed for use on plastic surfaces. Krylon plastic paint, for example, can be a good option, and you can find it at most hardware stores. You can also opt for a spray paint made for plastics, which can make it easier to achieve a smooth and even finish.
Prepare the work area:
Before you start painting, make sure you have a well-ventilated work area and lay down drop cloths or newspapers to protect the surrounding surfaces from paint splatters.
Prime the sink (optional):
Depending on the type of paint you choose, you may need to apply a primer first. Some paints, such as appliance paint, can be applied directly to the plastic, but always read the manufacturer's instructions on the paint can to determine if priming is necessary.
Paint the sink:
When you're ready to paint, follow the instructions on your chosen paint carefully. Apply thin coats of paint, allowing adequate drying time between each coat as per the manufacturer's recommendations. Typically, it's best to wait 7 to 10 days after painting before using the sink to allow the paint to cure fully and reach its maximum strength.
Maintenance:
Once your sink is painted and cured, you'll need to take some precautions to maintain its finish. Avoid using abrasive cleaning products or sponges, as these can scratch the paint. Keep a small amount of the paint you used for touch-ups, as scratches or dull spots may occur over time due to regular use.

Drying and curing the paint
Drying and Curing Process:
- After applying the base coat, allow it to dry completely. This is important because it forms the foundation for subsequent coats.
- It is recommended to use thin coats of paint rather than thick coats. This helps achieve even coverage and prevents areas of paint buildup.
- Once you are satisfied with the colour and have applied all the desired coats of paint, consider adding a clear coat for extra protection. The clear coat will act as a barrier against scratches and other types of damage while also enhancing the shine of your sink.
- Ensure that the clear coat you choose is compatible with both latex-based and oil-based enamels to prevent any issues during application or curing.
- After applying the final coat, whether it is the base coat or a clear coat, allow sufficient time for the paint to cure. Paint curing is essential to achieve its final strength and durability.
- Depending on the type of paint used, the curing process can take around 7 to 10 days. During this period, avoid using the sink to ensure the paint cures properly.
- Once the curing process is complete, you can start using your freshly painted sink.
Maintenance and Care:
- To maintain the appearance of your painted sink, wipe it down with mild soap and water after each use. This will prevent the buildup of food residue or dirt, reducing the chances of permanent staining or discolouration.
- Always dry the sink with a clean towel after use to prevent water spots from forming on the surface.
- If scratches or damage occur, touch them up with matching paint. Clean the area and ensure it is free of dirt and debris before applying the touch-up paint for optimal results.
- Avoid using harsh chemicals or abrasive cleaning products and sponges as they can damage the paint.
By following these drying, curing, and maintenance instructions, you can ensure that your painted plastic RV sink maintains its fresh and new appearance for a long time.

Maintaining the paint job
Cleaning and Maintenance:
Before using your newly painted sink, it's essential to allow the paint to cure completely. This process takes time, so refrain from using the sink for at least 7 to 10 days after painting. During this curing period, avoid any abrasive cleaning products, sponges, or pads, as they can damage the fresh paint. Once the paint has cured, you can start using the sink, but always be gentle and avoid harsh scrubbing. Use mild cleaning solutions and soft sponges or cloths to wipe down the sink, removing any dirt, soap scum, or residue. Remember to keep the area well-ventilated to prevent paint discoloration or damage.
Touch-ups and Repairs:
Over time, your painted sink will likely experience some wear and tear, such as scratches or dull spots. To address this, always keep some extra paint on hand. You can use this for touch-ups, carefully applying it to any areas that need a refresh. Make sure to follow the same painting technique and allow the touch-ups to cure fully before using the sink again. If you notice more significant paint chipping or peeling, you may need to consider repainting the entire sink to ensure a consistent finish.
Preventative Measures:
To prolong the life of your paint job, take preventative measures to avoid damage. Be cautious when handling sharp objects around the sink, as they can scratch the surface. Consider using a plastic scouring sponge for gentle cleaning, and always wipe down the sink after each use to prevent soap or water stains from building up. Additionally, keep the sink area well-organized and free from clutter to avoid accidental bumps or scrapes.
Long-term Care:
For long-term maintenance, periodically inspect the paint for any signs of wear or fading. Depending on the paint type and usage, you may need to consider repainting the sink every few years to maintain its visual appeal. Always keep a record of the paint brand and color used, so you can easily match it for touch-ups or future repainting projects. Additionally, regular deep cleaning of the sink and its surrounding areas will help prevent the buildup of dirt and grime, keeping your painted sink looking pristine.
Alternative Solutions:
If, despite your best efforts, the paint job fails or becomes severely damaged, consider alternative solutions. You may opt for a new sink, preferably made of stainless steel, which offers a more durable and long-lasting finish. Alternatively, explore second-hand options at local stores or online, where you might find a cheaper replacement sink. Remember, maintaining a painted plastic RV sink requires dedication and care, but with the right approach, you can extend the life of your paint job and enjoy a beautiful and functional space.
