Waterproofing canvas

[flint62]

Anyone have any advice or experience waterproofing canvas for tents and groundcloths?
Thanks. Kevin

I've used Thompson's waterseal with good results.
They sell Canvax in Panther Primitive & Cabela's -my buddy has used this and had good results (may be a bit pricy).
I've talked with a couple that use concrete sealer - I don't know if this is the same as Thompson's or what. From what I've seen of their lodges, they discolored.
Hope this helps,

I also have had good results with Thompsons water seal It takes a while for the odor to cure out, So I would hang what ever you used it on out in the weather and let it air out good, I have a ground cloth made from a painters drop cloth that I treated about 8 yrs ago and it has held up well
still water pruff and has been used alot and folded and rolled around my Blanket.

Thompsons makes the finished canvas extremely flammable. Not a good idea. Spend the extra, and buy a good grade of treated canvas (like Sunforger) to start with.

Thanks for the heads up about Thompsons and flammability. Do you know if the Canvak sold by Cabelas is flammable also?

Thanks Kevin

It's not supposed to be. :thumbsup:

Thompsons makes the finished canvas extremely flammable.

I know that it's flammable in the can (most spirit-based paints and finishes are). Are you sure that it's still flammable once the solvent has evaporated away? Experiences many years ago suggested otherwise.

friend of mine waterproofed his tent w/ a sprayer,this past weekend it still leaked, he had thought it was the ridge because he did it with tent up,and maybe didn't seal ridge area enough,but after respraying,, still leaked,anybody ever spray/waterproof both inside and outside of tent?? would it help? thanks!

I'm not certain mind you, but I'm gettin' the impression that doing both sides is pretty common practice for a tent/ shelter tarp. A ground cloth I would assume could be done on just the one side as long as you always put the dirtier side down it ought to work.

Just as a point of information it appears that Canvak does indeed make canvas flammable.
So i guess it's a case of pick yer poison when it comes to waterproofing
Kevin :hatsoff:

I hate to say this...but mostif not all of the water-resistiting chemicals or water proofing are flamible. It is the solvent in it for spreading it around that makes it that way. Read the ingrediants....it is all there. So, do you want to be wet or very carefull around flame? Haveing waterproofed MANY tipis and tents, there has been no problem with a camp going up in smoke...except my 12' tipi :shocked2: and that is another story. Common sence on anything we do here is to be expected and looked out for. And the fireproofing stuff washes out in a few good rain storms. We have to live in safety. :thumbsup:
