Methods to Waterproof Cardboard Cylinder Tubes

Waterproofing cardboard cylinder tubes is essential, especially if your crafting project involves exposure to moisture or liquids. Here are several effective methods you can use:

1. Clear Sealant Spray

Clear sealant spray forms a protective waterproof barrier on the surface of cardboard tubes. Follow these steps to waterproof your tubes using this method:

  1. Prepare the Tubes: Ensure the cardboard tubes are clean and dry before applying the sealant.
  2. Spray Application: In a well-ventilated area, hold the tube upright and spray a thin, even layer of clear sealant over the entire surface.
  3. Drying Time: Allow the sealant to dry completely according to the manufacturer’s instructions before handling or using the tubes in crafting projects.

2. Mod Podge Waterproof Formula

Mod Podge, a popular crafting adhesive, also offers a waterproof formula that can be used to seal and protect cardboard tubes. Here’s how to use it:

  1. Apply Mod Podge: Using a foam brush, apply a generous coat of Mod Podge waterproof formula to the outer surface of the cardboard tube.
  2. Even Coating: Ensure the entire surface is evenly coated with Mod Podge, paying extra attention to the ends and seams.
  3. Drying Process: Allow the Mod Podge to dry completely. For added protection, apply multiple coats, allowing each coat to dry before applying the next.

3. Waterproof Tape

Waterproof tape provides a quick and easy solution for waterproofing cardboard tubes. Follow these steps to use waterproof tape:

  1. Wrap the Tube: Starting at one end of the cardboard tube, wrap waterproof tape tightly around the entire surface, overlapping slightly with each turn.
  2. Seal the Ends: Once the tube is fully wrapped, ensure the ends are securely sealed with waterproof tape to prevent moisture from seeping in.
  3. Smooth Out Air Bubbles: Use your fingers to smooth out any air bubbles or wrinkles in the tape for a seamless finish.

4. Wax Coating

Wax coating provides a natural and eco-friendly way to waterproof cardboard tubes. Here’s how to apply a wax coating:

  1. Melt the Wax: In a double boiler or microwave-safe container, melt a block of wax until it becomes liquid.
  2. Dip or Brush Application: Dip the cardboard tube into the melted wax or use a brush to apply a thin layer of wax to the surface.
  3. Allow to Dry: Place the wax-coated tube on wax paper or a non-stick surface and allow it to dry completely. The wax will harden, creating a waterproof seal.


Waterproofing cardboard cylinder tubes is a simple yet crucial step in ensuring the longevity and durability of your crafting projects. Whether you prefer clear sealant spray, Mod Podge waterproof formula, waterproof tape, or wax coating, each method offers effective protection against moisture and liquids. By following these methods, you can confidently incorporate cardboard tubes into your crafting endeavors without worrying about water damage. So go ahead, unleash your creativity, and enjoy crafting with waterproof cardboard cylinder tubes!
