Canvas Seam Sealer

I've seen a few comments in the forums regarding sealing of the canvas, and more particularly, the seams. However, I have yet to see anyone post anything specific as to what product they are using.
Our 2014 X20E leaks terribly at the seams. After a good long rain, the canvas itself is dry, but the seams are very wet, to the point of soaking the mattress and/or pooling in the corners. It's not condensation. The rest of the interior canvas is dry (including the underside of the roof panel).
The main seams along the edge of the roof and down the corners are the worst. These are the "standing seams" and, of course, they naturally catch the most rain water running along them.
Any product reviews would be helpful.

We have not had this problem, but were tent campers for decades.
Perhaps tent seam sealer would work?
Hope you find a good solution.

Years ago we would use warmed candle wax or beeswax on leaky tent seams.

As a boy scout in the '60's, our tents were those giant, stinky, heavy green canvas things that leaked everywhere. Probably WW2 stuff. We used beeswax to fill the seams. Never got a badge for it.

I've been avoiding this thread! I have a HTT, and have not had my leaky seams. I camp a lot, including traditional tents still. I HATE seam sealers. They are a mess, everything sticks to it even years later.

If I really needed to do something would look at like "Tear Mender". I have used it on heavy canvas wall tents with good results. It reminds me of old white school glue .

I'll try to grab my can out of the HTT (at storage) to see the brand. We use a spray-on seam sealer on the tenting for the HTT as well as our Coleman dome and the kids tents when necessary. Seems (no pun) to last a couple of years. Sprays on clear, dries quickly, and no evidence of any residue. I'm still using the same can for maybe 5 years now - goes a long way!

This happened to me also this past summer.
I purchased a seam sealer from REI, waited until everything was completely dry, and followed the directions.
No problems since! ��
