Thread: Tent seam waterproofing

Got an older model MSR HubbaHubba and during recent wet trip it was leaking in a couple of spots on the main seam.
Also noticed the old seam sealer is flaking off in places. What’s the best option for waterproofing seams ?

I just done mine a couple weeks ago for the same reason with a coleman roll-on sealer.

I thought it was shit as it was like brushing on milk. But it dried well and seems to be malleable.

Havent had it in real heavy rain but it isint leaking so far.

Chainsaw, I've noticed mine is starting to do the same.
@R93 where did you get that stuff from?

Local sports shop in town. I will be in there tomorrow for a coffee so will see if there is any more and get a price if you want.

If you like DIY there is a recipe on the net somewhere for dissolving slicone rtv into white spirits then paint it on.
It works pretty good for around stitches etc and when dried off looks like a wet stripe down the fabric.

yeah , I just waterproofed my jacket like that. the water just beads off now. get some rtv silicone and turps. squeeze some silicone into a container ,then mix in some turps until it is real runny, then i just wiped it on with a rag. make sure you use gloves though , rtv is horrible crap to get off your hands. look on youtube for homemade siltarp videos and you will find some info.
