Creating a durable adult slip and slide requires selecting the right materials that can withstand heavy use and provide a smooth, safe sliding experience. From the type of plastic sheeting to the stakes and soap, every component plays a crucial role in the overall performance and longevity of your slip and slide. Here are the best materials to consider for building a durable adult slip and slide.

1. Heavy-Duty Plastic Sheeting

Polyethylene (PE) Plastic

  • Why it’s best: Polyethylene is known for its strength and durability. It’s resistant to tears and punctures, making it ideal for heavy use.
  • Thickness: Opt for a thickness of at least 6 mils (0.006 inches) to ensure the slide can handle the weight and movement of adults.
  • Width and Length: A width of 10-12 feet and a length of 50-100 feet are recommended to provide ample sliding space.

Vinyl Plastic

  • Why it’s best: Vinyl is highly durable and flexible. It offers a smooth surface for sliding and can withstand various weather conditions.
  • Thickness: Choose a thickness of 10-20 mils for a long-lasting slide.
  • Width and Length: Similar dimensions as polyethylene (10-12 feet wide and 50-100 feet long) are ideal.

2. Stakes and Anchors

Lawn Stakes

  • Material: Metal stakes are more durable than plastic ones. Choose galvanized steel stakes to prevent rust.
  • Size: Stakes should be 6-12 inches long to ensure they anchor the slide securely to the ground.

Tent Stakes

  • Material: Heavy-duty aluminum or steel stakes are best.
  • Size: Similar to lawn stakes, they should be 6-12 inches long for effective anchoring.

3. Padding and Safety Materials

Pool Noodles

  • Why they’re best: Pool noodles are flexible, easy to cut, and provide excellent padding along the edges of the slide to prevent injuries.
  • Installation: Secure them with waterproof tape or additional stakes along the sides of the slide.

Foam Padding

  • Why it’s best: Foam padding can be used under the slide to cushion the ground and provide a smoother sliding experience.
  • Thickness: Choose foam that is at least 1 inch thick for effective cushioning.

4. Water Delivery Systems

Garden Hose with Sprinkler Attachment

  • Why it’s best: A garden hose with a sprinkler attachment ensures even water distribution along the slide, keeping it slippery and fun.
  • Material: Heavy-duty rubber hoses are more durable and less likely to kink.
  • Length: Ensure the hose is long enough to reach the entire length of the slide.

5. Lubricants

Non-Toxic, Eco-Friendly Dish Soap

  • Why it’s best: Dish soap reduces friction, making the slide slippery. Choose a non-toxic, biodegradable option to protect the environment and users.
  • Application: Apply generously and evenly along the slide for optimal performance.

Silicone-Based Lubricants

  • Why it’s best: These lubricants are long-lasting and provide a super slippery surface.
  • Application: Use sparingly and follow the manufacturer’s instructions for safe use.

6. Repair Materials

Waterproof Tape

  • Why it’s best: Waterproof tape can quickly fix any tears or punctures in the plastic sheeting, ensuring the slide remains functional throughout its use.
  • Type: Choose a heavy-duty, UV-resistant tape for best results.

Patch Kits

  • Why they’re best: Similar to those used for inflatable pools, patch kits can provide a more permanent fix for larger tears or holes.
  • Application: Follow the kit instructions to ensure a secure and durable repair.

7. Optional Accessories

Inflatable Pool Crash Pads

  • Why they’re best: Placing these at the end of the slide provides a safe, cushioned landing area for sliders.
  • Material: Durable, puncture-resistant vinyl is ideal.

Water Pumps

  • Why they’re best: For larger slides, a water pump can ensure a continuous, high-pressure water flow, enhancing the sliding experience.
  • Type: Submersible pumps designed for outdoor use are best.


Choosing the right materials is crucial for creating a durable and enjoyable adult slip and slide. Heavy-duty plastic sheeting, robust stakes, effective water delivery systems, and the right lubricants all contribute to a safe and fun sliding experience. With careful selection and proper maintenance, your DIY slip and slide can provide countless hours of summer fun.
