diy waterproofing anyone?

[weedeater64]

Hello all,
I was wondering if anyone has tried waterproofing they're own ripstop or other fabric for a tarp, rather than paying an extra 3 or 4 bucks a yard? I think I'd like to do this and would love to here recomendations on what to use.

i've read discussions about that elsewhere. it seems that most of the folks felt like you would probably increase in weight a little (difficult to get the waterproofing material as uniform as in a commercial set up ).
also the water resistance could be a little more questionable, especially over time.
speer hammocks is the cheapest source of silnylon that i know of at $4.00 per yard.

That was my impression too. I think someone tried it, but it came out really heavy and not uniform. I think it is cheaper and easier just to order it. Especially when you figure in the time factor.

I've done it - it is heavier, but it is waterproof. I would only use it for items that would be difficult to make with sil-nylon (things with small parts) -- I absolutely would not recommend it at all for tarps, underquilts or any large item because of the extra weight and difficulty of applying the sil-mix to large pieces of cloth.

I used the mixture Blackbishop suggested to seal the ends on my Yellow catzilla tarp. It makes it think and heavy but I put several coats and probably too think.

I used the ReviveX Spray-on Water Repellent for Outerwear on a Taslan/Supplex poncho liner. Not water proof. It is a DWR coating. Works good as far as I can tell thus far. Heavier, undoubtly, but I didn't weight before and after so don't know ho much.

For ripstop, I wouldn't bother. Doesn't seem like it would be worth the hassle. Also, the factory applied stuff is a lot softer to the touch than the ReviveX. Maybe other DWR coatings are softer.

i've used the tent & gear proof in the past, when i had one of those leaky old (shudder) tent floors , but i wouldn't use it for a tarp for just the reasons already talked about (un-even, heavy, etc).
i believe i remember noticing an increase in weight of the tent after re-water proofing the floor just by picking it up.
and i remember dirt & stuff sticking to it more after that treatment, even after it had plenty of time to cure.
