I did a quick search and found this...
Don't know how well it would work, but might be worth a try.
does any one who has done this in the past have any long term observations to add.still working,will do it again,not worth it,if i do it again i will do it this way,ect.
i recently did a tarp.i mixed 5 to 1 mineral spirits by volume to my silicone.i used the dunking in a bucket technique.i ended up doing it twice as i think the first time i did not coat completly.i was getting some misting in heavy rain.make sure you pull it out and unfold it and dunk it back in a couple times for more even coating.i also had to do the seams with a heavyer mix.
the second time i did it i found it much easier to mix it ahead of time in a 64 oz juice jug(allmost perfect size for a 5 to 1 mix with a whole tube of silicone.).like so.put some medal bits like washers,ball bearings,or nuts in jug.add about 1/3 silicone.fill jug 1/2 way with mineral spirits.cap tightly.shake vigorously.the medal bits act like bearings in a spray paint can to stir the mix.keep adding silicone and shaking untill it is mostly disolved.then fill jug to top with mineral spirits.leave as little air as possible in jug,you can squeeze the jug to get rid of any air,then cap tightly.i believe if you leave an air pocket in jug some of silicone will harden.i left mine in the jug for 4 days before i used it.the silicone was completly dissolved.pour any leftover into a smaller jug(pop bottle maybe)making sure to squeeze out any air. pic of my mix
OK got a real off the wall question here would the diy-sil process work on silk as opposed to working with nylon
Ambulo tua ambulo.
has anyone tried the spray silicone? It says it is a lube, but I have some left over, so I may see if it will dry. Using a spray can seems much easier than mixing and dipping.
