Is Hemp Fabric Waterproof?

Hemp is a hydrophobic fiber made from plants that take time to absorb water. Therefore, if someone accidentally splashes water on you, you won’t get wet and feel bad about it.

Since hemp is a very absorbent fiber, it must be treated with a waterproofing agent to make it water-resistant and meet today’s waterproofing standards. A hemp canvas that is tightly woven may repel water for a short while, but it will quickly saturate.

How to Waterproof Hemp Fabric?

The process of waterproofing hemp fabric can be carried out at home using a variety of techniques.

Using Beeswax to Waterproof Hemp Fabric


Using a beeswax and oil mixture is the most typical method of waterproofing hemp fabric.

Since ancient times, beeswax has been used for a variety of purposes. Wax made by honey bees forms a barrier that renders fabrics waterproof when it is melted and applied to them.

Using beeswax and a little greaseproof or parchment paper, you can easily waterproof your fabrics at home. Grate the beeswax if you purchased a block and then cut it up into small pieces.

  1. Beeswax that has already been granted is an option as well, so this first step is skipped.
  2. Once your iron is extremely hot, set it to the highest setting and allow it to reach its maximum temperature.
  3. Lay out your fabric on top of one sheet of greaseproof paper that has been placed to protect your ironing board.
  4. Place a second sheet of greaseproof paper on top of the fabric after scattering some of the grated beeswax over it.
  5. After that, use your iron to press the paper’s top against the fabric until the beeswax melts and absorbs into it.
  6. If any gratings are missed, you might need to add more on top of the fabric.

Another method of using beeswax is to melt the entire block in a container over a pot of hot water on the stove or range, and then use a brush to apply the melted wax in small, firm circular motions.

  • Environmentally Friendly
  • Easy to apply yourself


  • The wax may re-melt in extreme heat (>65°c)
  • Not vegan friendly
