One of the easiest and most common ways to waterproof your bag is by using a rain cover. However, there are several methods you can employ to protect your belongings from water damage.
Methods for Waterproofing Your Bag
Here's a breakdown of several methods to waterproof your bag, ranked from simplest to more involved:
-
Use a Rain Cover:
- This is often the quickest and most convenient option.
- Rain covers are typically made from water-resistant or waterproof material, like nylon with a polyurethane (PU) coating.
- Many backpacks come with a built-in rain cover stored in a dedicated pocket.
- You can also purchase universal rain covers separately to fit a variety of bag sizes.
- Simply stretch the cover over your bag for instant protection.
-
Waterproof Spray:
- Apply a waterproofing spray designed for fabrics. Look for sprays specifically made for nylon, canvas, or the material of your bag.
- Follow the manufacturer's instructions carefully. Typically, you'll need to apply several light coats, allowing each coat to dry completely before applying the next.
- This method is better suited for light rain or splashes, rather than full submersion.
- Reapply the spray periodically, especially after washing or heavy use.
-
Waterproof Liner:
- Insert a waterproof liner inside your bag.
- These liners are typically made from PVC or TPU and are completely waterproof.
- This method protects the contents of your bag, even if the outer material gets wet.
- Consider using dry bags inside your main bag for added security for sensitive electronics or documents.
-
Seam Sealing:
- Seam sealing is crucial for bags with sewn seams, as these are common points of water entry.
- You can use seam sealant tape or liquid seam sealant.
- Apply the sealant to the inside of the seams, following the product instructions.
- This is especially important for backpacks or bags used in heavy rain or for outdoor activities.
-
Waxing (for Canvas Bags):
- Waxing creates a durable, water-resistant barrier on canvas.
- Use a specialized fabric wax or beeswax.
- Apply the wax evenly to the canvas and then use a heat gun or hairdryer to melt the wax into the fabric.
- This method can alter the appearance and feel of the canvas, making it stiffer and darker.
- This is a more permanent solution and not suitable for all types of bags.
