Hi. This is a re-visit to an earlier post.
I took a chance on some cheap fabric and would love some advice for making it work (if possible). I bought what I thought was silnylon from the WalMart bargain bin to make tarps for my family. Before I started sewing, I tested the fabric by forming a cup and filling with water. Some water did come through over a long period (hours). I sewed one, strung it up, and put the garden hose to it and it seemed to hold up. I charged ahead with the sewing, made 4 more and hoped for the best - I ran out of money to buy other fabric anyway. I guess the fabric is just a DWR ripstop so, of course, now that we have used them a few times, the tarps bleed like crazy in a rain and sag with moisture from dew. With so much time and effort invested, I hate to scrap them.
Is there any treatment that will make them usable? I sealed the center seams with diluted silicone and that has worked just fine, is it possible to somehow apply that to the whole tarp? What about a ScotchGaurd type product? All advice is appreciated.
Thanks, Ray
