Clean the slide

To refinish a plastic slide, the first step is to clean it. Cleaning the slide will remove any dirt that has built up over time, which can make the slide less slippery and less fun for kids to use. Here is a step-by-step guide to cleaning a plastic slide:

First, use a scrub brush to clean the surface of the slide. This will help to remove any dirt, dust, or debris that has accumulated on the slide. Make sure to scrub all areas of the slide, including the top, sides, and bottom. Pay extra attention to any areas that seem particularly dirty or stained. You can also use a mild detergent or soap with the scrub brush to help lift away any stubborn dirt or grime.

Next, rinse the slide thoroughly with clean water. You can use a hose to do this, making sure to direct the water flow from the top of the slide to the bottom, washing away any remaining dirt and detergent residue. Ensure that all soap or detergent is rinsed away, as leftover residue can make the slide slippery and potentially unsafe for use.

If there are any particularly tough stains or discoloured areas on the slide, you may need to use a stronger cleaning agent. One option is to use a plastic-specific cleaner or restorer, such as Polytrol, which is designed to restore sun-faded plastics. Apply the cleaner according to the manufacturer's instructions, and be sure to test it on a small area first to ensure it doesn't discolour or damage the plastic.

After cleaning, it is important to dry the slide thoroughly. You can use a clean cloth or towel to wipe down the surface, ensuring no water spots or residue are left behind. Make sure the slide is completely dry before allowing anyone to use it, as a wet slide can be unsafe and may also cause water stains.

Finally, inspect the slide for any remaining dirt, stains, or discolouration. If necessary, repeat the cleaning process until the slide is completely clean. A thorough cleaning will ensure that the slide is ready for the next steps of the refinishing process, such as applying a wax coating or polishing.

Smooth the surface with sandpaper

To refinish a plastic slide, one of the steps is to smooth the surface with sandpaper. This is an important step as it helps to remove any scratches or imperfections on the slide's surface, ensuring a smooth and even finish.

Before sanding, it is recommended to use a heat gun or torch to restore the plastic. This helps to smooth out any micro-cracks and small scratches, revitalizing the colour and intensity of the plastic. It is important to be cautious when using a heat gun or torch, as the plastic should be melting, not burning. The key is to keep the heat source moving to avoid transferring too much heat to the plastic.

Once the surface has been heated and any major imperfections smoothed out, you can begin sanding. It is recommended to use a fine-grit sandpaper, such as 1600-grit, to get a smooth surface. Sand the slide gently and evenly, applying some elbow grease as needed. If there are any welds on the slide, use 80-grit sandpaper to smooth them out, then progress to finer grits like 180 and 320 to reduce the coarseness of the sand scratches.

After sanding, be sure to wipe away any sanding dust before proceeding to the next steps of refinishing. It is important to note that sanding may not completely restore the slide to its original appearance, but it will create a smooth surface for the next steps of the refinishing process.

Additionally, if you plan to paint the slide, sanding is crucial to create a rough surface for better paint adhesion. However, if you're aiming for a glossy finish, be mindful that sanding may affect the final look, so consider using a primer first.

Apply wax

Applying wax is an effective way to make a plastic slide slippery again. Car wax is a popular choice for this purpose, and it can be applied in a few different ways.

One method is to use wax paper, which can be rubbed over the entire slide surface to transfer the wax onto the plastic. This is a preferred method when considering the safety of children who will be using the slide, as it ensures an even and controlled application of wax. It is important to ensure that the wax is non-toxic, non-irritating, and won't stain clothes.

Another option is to use spray-on wax, which can achieve a similar effect of restoring the slide's slickness. A specific type of spray-on wax recommended by some parents is a ceramic car wax. This type of wax is designed to last for several years, depending on the climate.

Additionally, candle wax can be used to make a slide slippery. Rubbing candle wax on a slide can create a super-slippery surface after a few runs.

It is worth noting that while waxing can enhance the slide's slickness, it is crucial to first address any dirt or grime on the slide's surface. Proper cleaning will ensure that the wax application is more effective and long-lasting.

Use a heat gun

Using a heat gun is a common method for restoring a plastic slide. It can smooth the surface and revitalise the colour and intensity of the slide by melting away small scratches.

To begin, ensure that the plastic slide is made of polypropylene or polyethylene. These types of plastic can be remelted and reshaped with a heat gun. The heat deflection for these plastics is in the 140 to 150 °F range. When using the heat gun, it should not look like the plastic is melting; instead, the surface will appear to be saturated with oil. Move the heat gun in quick, sweeping motions across the slide. Avoid holding the heat gun in one place for too long, as this may burn the plastic.

After treating the slide with the heat gun, you can polish the slide with wax or beeswax to make it slippery. Car wax or spray-on ceramic car wax can be used to achieve this effect.

Paint the slide

Painting a plastic slide can be a great way to refresh its appearance and protect the surface. Here is a step-by-step guide to help you through the process:

Prepare the Slide Surface:

Before painting, it is essential to prepare the slide surface. Start by cleaning the slide thoroughly with a scrub brush to remove any dirt, grime, or residue. This ensures that the paint adheres properly to the plastic surface.

Sand the Slide:

Lightly sand the slide using fine-grit sandpaper. Sanding creates a rough surface, improving paint adhesion. It is crucial not to over-sand, as this may damage the plastic. Wipe away any sanding dust before proceeding to the next step.

Prime the Slide:

Apply a plastic-specific primer to the slide. Priming ensures better paint adhesion and helps the paint job last longer. Choose a primer that is suitable for plastic surfaces and apply it in even, light coats as per the manufacturer's instructions.

Choose the Right Paint:

Select a paint specifically formulated for plastics. Popular options include Krylon Fusion, Rust-Oleum Universal, and Rust-Oleum Painter's Touch 2X Ultra Cover. Check the paint can for temperature requirements and ensure that the paint is suitable for outdoor use if the slide is exposed to the elements.

Spray painting is the preferred method for painting a slide. Set up your work area outdoors or in a well-ventilated space to manage fumes and overspray. Protect the surrounding area with a tarp, plastic sheet, or cardboard to catch any paint overspray.

Follow the manufacturer's instructions for the chosen paint, ensuring the slide surface is within the recommended temperature range for painting. Apply light, even coats of paint to the slide, allowing adequate drying time between coats.

Buff and Smooth:

Once the paint has dried, you may want to lightly buff the slide with superfine sandpaper to ensure a smooth surface. This step is especially important if the slide is intended for children to play on, as it helps create a slick surface for sliding.

Apply a Protective Coat:

Consider applying a clear protective coat over the painted surface. This extra step can enhance the durability of the paint job and provide additional protection against the elements.

Remember to follow all safety precautions when working with paint and solvents, and always work in a well-ventilated area. With these steps, you can give your plastic slide a new lease of life, making it both functional and aesthetically pleasing.
