I just want to confirm, is this the stuff people use to seamseal tarptents? http://www.homedepot.ca/product/ge-silicone-ii-window-door-sealant-clear-290-ml/941917

I was at home depot and figured I would pick up a tube. I just wanted to get confirmation before I mix this stuff up and put it on my tent this weekend. Thanks!

That's what I used. It's also what Henry sends out if you order silicone from him.

Set your tent up TIGHT so you have good flow into the stitching. Otherwise, if you just "cover" the stitching, you'll have gaps when the wind stretches the fabric.

Mix it to "warm honey" consistency and apply it with a needleless 10cc syringe.
Work it in with the tip.
Excellent control.

Give it Plenty of time to dry.

I also keep it around for small holes/tears in the fabric of the tent floor. Works great.

You can also make custom insoles with it! There are some instructions on the web, but basically make a layer, cover with plastic wrap, and make impressions with your feet. Trim to fit. There are other DIY insole options out there, but none so simple.

With mineral spirits. Go to Tarp Tent's website. They have a nice video on the topic.

Permatex Flowable Silicone Windshield & Glass Sealer works well too. I used this for the first time a couple of months ago to seal up my TarpTent Moment DW and it worked great. No mixing necessary since it comes in a good consistency. Furthermore, it's already in a conveniently sized tube with applicator tip that allows you to work the silicone into the seam and lay a nice bead. Similar to applying caulk around the home, I cut the applicator tip at a 45 degree angle and pushed the bead of silicone across the seam. After that, I ran a folded rag across the bead to wipe off the excess. It did cure a bit more "glossy" than when I've used the GE Clear Silicone II + mineral spirits mixture, but still a very light and tidy application. A much cleaner appearance then anything I've done in the past.

+ 1, 2, 3, & 4 for what Alex said!

Permatex Flowable Windshield Sealant

I use a short, stiff disposable foam rubber brush to apply it after squeezing out a small amount onto the tip of the brush from the tube. Working the brush sideways along the seam has given me great results.

One $5.00 tube goes a lot farther then you would think. ;-)

While you are sealing your tarptent on 05/17/2013 11:43:22 MDT Print View

The bathtub in Tarptents are pretty slick and things move around a lot. Henry told me to brush a few swatches of the sealent ont eh bottom as this will give you a few "sticky" spots. I have two 2" bands across the bottom of the tent where my shoulder and butt would touch. To thin it, I used white gas, worked great. Best wishes - Jon

There's been a lot of chatter about silicone. While some people have had great success with GE II mixed with silicone others have had it flake/peel off quickly. The chemistry gist is that different thickness/viscosities of silicone formulas are not simple additions of mineral spirits. Any thinner you add will alter the chemistry and result in a weaker solution.

Hence people love the flowable windshield sealer from permatex. It's designed to be thinner out of the tube without weakening the final coating/seal. I'm sure GE makes a similar product, but haven't looked into it since permatex is readily available from auto stores.

Silnet on 05/17/2013 13:23:03 MDT Print View

Interesting that no one is mentioning the McNett Sil Net product that is specifically formulated for silicone impregnated nylon fabrics and sold in backpacking stores everywhere... and it flows.

Wow a lot of responses, I haven't found permatex flowable in stores around my area. I'm having doubts about this stuff now. I think I may just pick up silnet from MEC.

Advance Auto Parts has it. Is there a location near where you are located?

Patrick, everybody is an expert but do keep in mind that thousands of tents have been done with the GEII stuff.
I mostly use the local equivalent mixing it with Mineral Turpentine (paint thinner)
Here is my backyard a few days ago :
Seam sealing
(not that other ways don't work....)
BTW, those are not mine. I just seam sealed them for customers.

Franco.... you've proven that not all hoarding is bad. That's quite a fleet you have three. Looks like you have backups for backups.

5 or 10 parts mineral spirits to 1 part silicone

mix for maybe 10 minutes - that is, stir, wait a few minutes, stir agains,... until all the silicone is disolved

I got some "odorless" mineral spirits once that worked fine. Another time I got some odorless mineral spirits and it was watery and I didn't even try it - maybe just use regular mineral spirits

due to clean air regulations in some places some manufactures have reformulated Mineral spirits to reduce volatile organic compounds (low VOC). Low VOC mineral spirits don't work well with silicone. One alternative to Mineral spirits is White Gas.

Permatex Flowable Silicone Windshield & Glass Sealer as mentioned earlier doesn't need to be thined. You can find this at auto parts stores.

regular mineral spirits works

maybe in some locations they don't allow it and only have the watery stuff that doesn't work well

I didn't even try it. Maybe I'll use it for wasing oil paint off brushes?

white gas produces explosive fumes so you have to be very careful, like use it outside. And white gas might disolve the fabric you're applying it to? It is very nasty stuff.
