canvas waterproofing

Question:

I always found canvas tents to be waterproof on their own. The swelling of the fibers when damp sealed the fabric.  The trick was not to touch the canvas on the inside when it was wet. That set up a wick.

Hello, I am in search of a product that I can use to water proof a canvas tent.  My main concern is that it helps prevent the growth of mildew. The other concern is that I don’t want a petroleum based waterproofing material because there will be a woodburning stove in the tent. Thanks! — Freestone

This is the only waterproofer I know of that bills itself as non-flammable: http://www.nikwax.com/index.asp — ** Pull the plug (remove plug.) from my e-mail address to reach me ** Michael Doran Random Orbits Design

I once used a product called "Safe ‘n Dry Fire Retardant and Water Repellent" on a tent which I was taking winter camping and wanted to cook in. Came in a gallon can and was painted or sprayed onto canvas or nylon. Although it contained a flammable solvent it claimed that when that had dried out, it actually acted as a fire retardant (to UL standard) It contained a suspended powder, which I guess was the active ingredient, and had to be stirred frequently. It worked well but left the fabric stiff and a bit streaky, but that may have been because it was a dark coloured lightweight nylon. You probably wouldn’t notice it on light coloured canvas. In fact I probably have half a can in my basement but have no way of getting to you. I tried a web search on that name but found nothing useful. May be sold under a different brand name in the US (I’m in Canada). Could try looking in the yellow pages under canvas and awning companies. Good luck,                  Ken.
