What You'll Learn
Sanding and priming
Sanding:
Before you start sanding, make sure you have the right type of sandpaper. For plastic surfaces, it is recommended to use super-fine sandpaper to create a smooth finish. The specific grit number will depend on the desired level of smoothness, but generally, a higher grit number will result in a finer finish. It is also important to consider whether to use wet or dry sandpaper. While dry sandpaper is commonly used, wet sandpaper can provide a smoother finish and reduce the risk of scratching the plastic.
Once you have the appropriate sandpaper, start by lightly sanding the entire slide. This will help create a rough surface for the paint to adhere to. Pay extra attention to any areas that may have existing paint or varnish. Sanding these areas thoroughly will help the new paint adhere better and create a more uniform finish. Be sure to wipe down the slide with a damp cloth to remove any dust or debris created during the sanding process.
Priming:
Priming is an essential step in painting plastic as it helps the paint adhere better and creates a more durable finish. Choose a primer that is specifically designed for plastic surfaces. You can find these primers at most hardware stores or home improvement centres. Make sure the slide is clean and dry before applying the primer. Use a paintbrush or a roller to apply a thin, even coat of primer to the entire slide. Allow the primer to dry completely according to the manufacturer's instructions. Depending on the primer used, you may need to apply multiple coats for the best results.
After the primer is dry, lightly sand the slide again with super-fine sandpaper. This step will help create an even smoother finish and ensure that the slide's surface is ready for painting. Remove the sanding dust with a tack cloth or a damp cloth before moving on to the painting stage.
By properly sanding and priming the plastic slide, you will create a strong foundation for the new paint to adhere to. This will result in a smoother, more durable finish that can withstand the elements and the wear and tear of regular use.

Spray painting
Prepare the Slide:
Start by giving the slide a thorough cleaning. Use a mild detergent, a rag, and a good scrub to remove any dirt, debris, or leftover residue. You can also use a pressure washer for this step if you have access to one. Make sure the slide is completely dry before moving on to the next step.
Choose the Right Paint:
It's important to select a paint that is specifically designed for use on plastic surfaces. Look for options like Rustoleum's Universal Paint and Primer in One, which offers smooth, even coverage and adheres well to plastic. Choose a colour and finish that suits your desired aesthetic.
Apply the Paint:
Before you begin painting, lay down a tarp or plastic sheet to protect the surrounding area from paint spray. Hold the can of spray paint about 10-12 inches away from the slide and apply even coats, using smooth, steady strokes. Allow each coat to dry completely before applying the next. Depending on the desired coverage and durability, you may need to apply multiple coats.
Ensure Durability:
To ensure the paint job's longevity, consider applying a clear topcoat or sealer specifically designed for outdoor use. This will provide an extra layer of protection against wear and tear, ensuring the paint doesn't chip or fade too quickly.
Make it Slippery:
If you want to restore the slide's slickness, there are a few options. You can try using a polycrylic spray to add a sheen that might increase slipperiness. Alternatively, you can use the old-fashioned method of wax paper. Have kids sit on wax paper before sliding down, which will transfer a thin layer of wax to the slide, reducing friction and making it faster.
By following these steps, you can transform your plastic slide and give it a fresh new look. Just remember to always work in a well-ventilated area when spray painting and take the necessary precautions to protect your skin and eyes from paint exposure.

Paint type and colour
When it comes to painting a plastic slide, the type of paint and colour you choose are important considerations. Here are some detailed instructions and tips to help you select the right paint and colour for your project:
Paint Type:
- Spray Paint: Spray paint is the most commonly recommended option for painting a plastic slide. It allows for even coats and helps achieve a smooth finish. Look for spray paint that is specifically designed for plastic surfaces, such as Krylon Fusion for Plastic or Rust-Oleum Painter's Touch 2X Ul.
- Primer: It is crucial to use a primer before painting to ensure better adhesion of the paint. Choose a plastic primer spray and apply a thin, even coat over the entire slide. Allow the primer to dry according to the manufacturer's instructions, usually about 1-2 hours.
- Clear Sealant: For added protection and durability, consider using a clear sealant spray that is compatible with your chosen paint. This will help extend the life of your paint job.
Paint Colour:
- Light Colours: If the slide is in direct sunlight and tends to get too hot, consider using light colours to help reduce the amount of heat absorbed. Light colours may also help the slide blend in better with its surroundings.
- Matte Finish: A matte finish is recommended over a glossy one, as it tends to hold up better and may provide a more subtle look.
- Safety: If toddlers will be using the slide, ensure that the paint is non-toxic and safe for children. Avoid paints with harmful chemicals that may cause health issues if ingested or touched.
Remember to always follow the manufacturer's instructions for drying time between coats, and consider allowing the slide to cure for a full week before use for maximum durability.

Number of coats
When painting a plastic slide, it is important to consider the number of coats of paint to be applied. Applying multiple thin coats of paint is recommended instead of a single thick coat. This technique helps to prevent drips and ensures a smooth finish. Typically, two to three coats of paint are suggested for a plastic slide. However, some sources mention that one or two thin coats are sufficient, while others recommend up to six cans of spray paint for an 8-foot slide, resulting in three coats.
Allowing adequate drying time between each coat is crucial. The drying time can vary depending on the paint manufacturer's instructions, but it typically ranges from 15 to 30 minutes. It is important to follow the manufacturer's instructions for optimal results. Additionally, the weather conditions during painting should be considered, with dry days, minimal humidity, and temperatures between 50°F and 85°F being ideal.
After applying the final coat of paint, it is recommended to let the painted slide cure for at least 24 to 48 hours before use. For maximum durability, extending the curing time up to a week is beneficial, especially if the slide will be exposed to outdoor elements. This extended curing period helps protect the paint and ensures its longevity.
To enhance the durability and protection of the paint, consider applying a clear sealant spray specifically designed for use with your chosen paint. The sealant serves as a finishing coat and can be selected with a shine, semi-shine, or matte finish. It is important to note that the sealant should only be applied once the paint is completely dry.
The number of coats required may also depend on the type of paint chosen. For instance, high-gloss paint might require fewer coats compared to matte paint. Additionally, proper preparation of the slide surface before painting, including cleaning, sanding, and priming, can impact the number of coats needed. Adequate preparation helps ensure better paint adhesion and a longer-lasting finish.

Cleaning
To keep your slide in good condition, it is important to clean it regularly. Over time, slides can accumulate dirt, bird droppings, scum lines, and other surface contaminants, which can make the slide less slippery and less fun to use. You can use a specialised detergent like SlideDetergent™ to effectively dissolve these contaminants without leaving any residue or altering the water chemistry of a pool.
Polishing
In addition to cleaning, you can also polish a plastic slide to make it slippery again. One way to do this is by waxing the slide. You can use wax paper or spray-on wax to achieve a slick surface. Just make sure to use a non-toxic, non-irritating, and stain-resistant product, especially if children will be using the slide.
Painting
If your slide is looking faded or you simply want to change its colour, you can paint it. Spray paint is a good option, and it's best to do this outdoors due to the fumes and overspray. Apply even coats of paint, allowing each coat to dry completely before applying the next. Depending on the desired durability, you may need multiple coats. For example, one project used three coats of paint and an exterior sealer, while another used six cans of spray paint on an 8-foot slide.
Repairing
For more significant damage, such as holes, you may need to repair the slide using a plastic welder. This can be a cost-effective alternative to replacing the slide, as replacement components can be expensive. The process involves using a nitrogen plastic welder and an airless plastic welder to smooth out and fill in the damaged area. After welding, you will need to sand the area with progressively finer grit sandpaper to achieve a smooth finish.
