Also, when i say 'mix' you will need a bucket and one of those paint or drywall compound mixers you use in a drill. I dont think it'll work too well if you just shake or stir.
Your tarp can be made waterproof by turning it into silnylon. Its not that hard to brew your own. Mix paint thinner with 100% silicone caulk, and dip the tarp. Let it soak for a while, then wring it out as best you can. Then stretch it out to dry.Save the leftover for seam sealer and spot waterproofing in a gatoraid bottle.Results are ok, not as light as commercial silnylon but it should do.
