Natural Wax to Protect Fabrics

Natural Wax to Protect Fabrics

Granddad Jack’s Sack Wax is a beeswax based product that waterproofs and protects many types of fabrics while allowing them to continue to breath. Sack Wax is our own formula that uses 100% natural ingredients to add life and character to bags, clothing and other items. The uses are numerous.

Waxed Fabric has been around for hundreds, perhaps thousands of years. It had its beginnings in maritime history when sailors added oils and waxes to their sails to make them water resistant and more efficient. Read more on the history of waxed canvas here.

Whereas Paraffin wax, a petroleum byproduct, was the most popular choice for fabric wax in the past, we have developed a product based on the amazing properties of beeswax and coconut oil. We believe the benefits of these ingredients add greater value to Granddad Jack’s Sack Wax. To learn more about the benefits of fabric wax read this article.

How to use Granddad Jack’s Sack Wax

NOTE: Applying Sack Wax could cause the colour of the fabric to darken and it will cause it to become slightly stiffer. Stretch fabrics are virtually impossible to wax and wont perform as well as non-stretch fabrics

What you will need:

  • Granddad Jack’s Sack Wax
  • A clean stable table or flat area
  • A hair dryer or some warm sunlight


  1. Completely empty the bag or pockets of the item you are about to wax
  2. Remove loose materials such as dust, mud, etc. You can do so using a hard brush but if you decide to wash the bag or otherwise wet it, let it dry thoroughly before applying the wax.
  3. Starting in one spot begin rubbing the wax cake onto the fabric. Apply a good, even coating over as much of the surface as you can. Periodically use your finger to rub the surface of the waxed fabric in order to even out the coverage and encourage the wax into the fibres.

    NOTE: Sack Wax works by creating a flexible membrane between the fibres. In basic terms it reduces the gaps between the fabric fibres making it difficult for water to get in. If further obstructs water by causing droplets to bead together into larger globules and run off the item with gravity. The advantage to this over other forms of waterproofing using plastics is that waxed fabric still allows small amounts of air in and out so the fabric can breathe and resist overheating and mould.

    1. Spend time on seams and areas with heavy stitching because these have larger holes and gaps that need protection
    2. When a sufficient area has been covered, heat is often needed to dissolve the remainder of the Sack Wax into the fabric. To achieve this you can place the item in sunlight or use one of the following methods
      • A hairdryer or heatgun
      • A clothes dryer
