Waterproofing your canvas backpack
One of the features of a canvas backpack that makes them so durable and popular is the waterproof barrier on the material. This barrier means if you get caught in the rain at the bus stop, while hiking, or walking through campus to class, your backpack and its content will not get ruined.
After time and after cleaning, you will want to replace this barrier to keep the waterproofing at its best. To waterproof your canvas backpack, you will need your water shield spray and a bath towel. It is important to remember your backpack must be completely dry before applying waterproofing spray to it. The steps to follow are:
- Place a bath towel in your backpack to make it easier to apply the spray while holding its shape.
- Following the directions on your product, hold the can 6-8 inches from the surface and slowly, evenly, and uniformly spray your backpack. Do not saturate the bag with the spray. The spray may darken the fabric slightly. You do not have to worry. It will lighten in color as it dries.
- Place your bag with the towel still inside somewhere cool to dry.
Your clean and waterproofed backpack will be ready to use as soon as it is dry. You can remove the bath towel and pack full of all your school or hiking things again.
