If your Camper is new, it may leak the first few times it is out in rain due to the stitching not yet "taking up" in the needle holes. We always recommend wetting down your Camper before use. This process will need to be repeated 2 to 3 times before your canvas will be water proof. If your Camper is older and has developed leaks or is taking in water, check out our accessories page for a range of products we stock that can restore water proofing and remove mould.
