The OZtrail Aqua Proof Spray Can is a great waterproofing agent, restorer and fabric protector. We recommend applying a small test patch and let it dry for 24 hours to ensure there is no adverse effect of colour change.
 
Directions: Shake can well before use. Make sure the material is clean and dry before applying. Spray a thin coat then allow approximately 3 hours for the material to dry. Second coat may be needed for older worn canvas.
For new canvas, please consult the manufacturer before applying due to existing treatment that may have already been applied.
