Method 1 - You Will Need:

  • Item You Want to Waterproof (e.g. cushion, piece of fabric, or apron)
  • Waterproofing Spray for Fabric
  • Scrap Cardboard

Method 2 - You Will Need:

  • Item You Want to Waterproof (e.g. cushion, piece of fabric, or apron)
  • Steamer
  • Large Glass Bowl
  • 4oz of Beeswax Pellets
  • 4oz of Paraffin Wax
  • Scrap Cardboard
  • 1” wide Paintbrush
  • Wooden Spoon
  • Clothes Dryer
  • Heat Gun or Hair Dryer

METHOD 1: Waterproof Fabric Using a Spray Steps:

  1. If you’re spraying a small item like an outdoor cushion or your favourite apron, take it outside and lay out some scrap cardboard on the grass or patio.
  2. Place your item on the cardboard and lightly spray over its entire surface with the fabric spray, holding the can approximately 6 inches to 8 inches away.
  3. Flip the item over and spray the entire surface again. Leave to dry completely, as directed on the can, before applying a second coat to both side. Leave to dry again before testing it out!

Method 2: Waterproof Fabric with a Wax Coating Steps:

  1. Boil water in the bottom part of your steamer and rest a large glass bowl on the top part; ensure that the water doesn’t boil over and touch the bottom of the bowl. Place in the beeswax pellets with the chopped up paraffin wax.
  2. Stir together until the chunks of wax melt and liquefy. Meanwhile, put your chosen fabric into the dryer and set it on high for 5 minutes to warm up the material.
  3. Once the wax has completely melted, cover a surface with scrap cardboard and place your item on top. Coat a paintbrush with the molten wax mixture and brush it over your fabric. Work in small sections until the item is completely covered.
  4. Dry the entire layer with a heat gun or a hairdryer on the highest setting; you want the wax to soak into the fabric itself. Leave to dry completely for a few hours.
  5. Once the item is dry, check for any uncoated spots and brush over them with more wax. If you need to cover the entire item again, heat up the steamer to melt the mixture once more.
  6. Leave the item alone for 24 hours to cure. Afterwards, it should be completely dry and waterproof. If you smell a strong odour of wax
