How to Fix a Cracked Plastic Slide

What do you do when your children play on their plastic slide, and it cracks? Depending on the severity of the crack, there are a few ways that you can fix it. However, a broken slide can be dangerous, so it’s best to take care of the issue as soon as possible.

How to Fix a Cracked Plastic Slide

Summary: Swimmer’s hair can be tricky to manage, but there are a few tips to help. First and foremost, it’s important to avoid chlorine and other harsh chemicals found in pool water. To do this, wear a swimming cap when swimming and rinse your hair with fresh water after each swim. Conditioning your hair regularly will also help keep it hydrated and prevent damage caused by chlorine.

Five Common Reasons That Causes a Broken Plastic Slide

1. Lack of Maintenance

A broken slide can often be the result of a lack of maintenance. You should keep the slide surface clean and clear of any debris or trash that could cause someone to slip. In addition, if the slide is used often, you will need to wax it regularly to keep it safe and slippery.

2. Heavy Use

A slide that is used a lot can get damaged. The friction from people’s feet can make it wear down and crack. If you have a heavily used slide, check it often for damage. A small crack can be fixed with superglue, but a bigger crack might need a new slide.

3. Weather Damage

Another common cause of slide damage is weathering. Extreme temperature changes can cause the plastic to crack and break. If you live in an area that experiences extreme weather conditions, it is important to take steps to protect your slide from the elements. You can do this by covering it with a tarp or a slide cover when it is not in use.

4. Heat Damage

Direct sunlight or exposure to heat can cause the plastic to warp, crack, or even melt. Therefore, if your slide is in a sunny spot, it is important to ensure that it is shaded by the sun. You can do this by planting trees or shrubs around the slide or installing a shade cloth.

5. Poor Maintenance

If you don’t clean your slide regularly, it can get damaged. Clean it with a damp cloth to keep it in good condition.

14 Easy Steps on How to Fix a Cracked Plastic Slide

Step 1: Assess the Damage

Begin by inspecting the cracked plastic slide to determine the extent of the damage. Check for any sharp edges or jagged pieces that may pose a safety hazard. Note the location and size of the crack, as this will help you determine the best repair method.

Step 2: Gather the Necessary Materials

Gather the materials you’ll need for the repair process. These may include:

  • Plastic adhesive or epoxy specifically designed for plastic repair
  • Sandpaper (ranging from 80- to 220-grit)
  • A clean cloth or rag
  • Rubbing alcohol or acetone
  • Paintbrush or applicator for the adhesive
  • Clamps or heavy objects to apply pressure during the curing process

Step 3: Clean the Area

Before starting the repair, clean the cracked area thoroughly. Use a clean cloth or rag dampened with rubbing alcohol or acetone to remove any dirt, grease, or debris from the surface. Allow the area to air dry before moving on to the next step.

Step 4: Sand the Area

Sand the area around the crack with 80-grit sandpaper to create a rough surface for the adhesive to bond to. Be sure to sand at least one inch around the entire crack. After sanding, use a clean cloth or rag to remove dust or debris.

Step 5: Apply the Adhesive

Read the instructions on the plastic adhesive or epoxy packaging carefully to ensure proper application. Use a paintbrush or applicator to apply the adhesive to both sides of the crack, covering the entire sanded area. Make sure the adhesive is applied evenly and extends slightly beyond the edges of the crack. For larger cracks, you may need to apply multiple layers of adhesive, allowing each layer to dry according to the manufacturer’s recommendations before applying the next one.

Step 6: Align the Crack

Carefully align the two sides of the crack, pressing them together firmly. Ensure that the edges are properly aligned and that there are no gaps or misalignments. This is crucial for a strong and effective repair.

Step 7: Apply Pressure

Once the adhesive has been applied and the crack is properly aligned, use clamps or heavy objects to apply pressure to the repaired area. This will help the adhesive bond the two sides of the crack together and create a strong repair. Follow the adhesive manufacturer’s recommendations for the amount of pressure and duration of the curing process.

Step 8: Allow to Cure

Allow the adhesive to cure for the recommended amount of time, which can vary depending on the type of adhesive used. Curing times can range from a few hours to several days. Do not use the slide or subject it to any stress during this time, as this could weaken the repair.

Step 9: Sand the Repaired Area

Once the adhesive has fully cured, remove the clamps or heavy objects. Use 220-grit sandpaper to smooth the repaired area and remove any excess adhesive or rough edges. Be careful not to sand too aggressively, as this could weaken the repair or damage the surrounding plastic. Sand in a circular motion, blending the repaired area into the surrounding plastic to create a seamless appearance.

Step 10: Clean the Area Again

After sanding, use a clean cloth or rag dampened with rubbing alcohol or acetone to remove any dust or debris from the repaired area. Allow the area to air dry completely before moving on to the next step.

Step 11: Apply a Sealant (Optional)

If you want to add an extra layer of protection to the repaired area, you can apply a clear plastic sealant. This step is optional but can help protect the repair from UV damage and further wear and tear. Read the instructions on the sealant packaging for proper application and drying times.

Step 12: Paint the Repaired Area (Optional)

If the repaired area is visible and you want to restore the slide’s appearance, you can paint the area to match the rest of the slide. Choose a paint specifically designed for use on plastic and follow the manufacturer’s instructions for application and drying times. Ensure that the paint is safe for use on children’s play equipment and non-toxic.

Step 13: Inspect the Repair

Once the paint and sealant (if applied) are completely dry, inspect the repaired area to ensure that the crack is no longer visible and the surface is smooth to the touch. Check for any sharp edges, uneven surfaces, or areas where the adhesive may not have bonded properly. If you notice any issues, repeat the necessary steps to correct them before allowing the slide to be used again.

Step 14: Monitor the Repair

After completing the repair, it’s essential to monitor the area over time to ensure the repair remains strong and effective. Regularly inspect the slide for any signs of the crack reopening, new cracks forming, or the adhesive losing its bond. If you notice any issues, address them promptly to maintain the safety and integrity of the slide.

By following these steps, you can successfully repair a cracked plastic slide and restore its functionality and safety. Regular maintenance and inspections will help ensure that the slide remains in good condition for years to come.
