How to Waterproof a Canvas Tarp
The best product to waterproof a canvas tarp or tent is the good stuff that contains no chemicals, linseed oil, or turpentine. These are all extremely flammable when melting the waterproofing wax. As well, they do not contain the essential oil to draw the wax deep into the fabric which will cause cracking and flaking.
