It has been a while since I last sealed the seams on my CCS tarp. It is still waterproof but I was wondering how often people touched up their sealing.

I'm in the "when it starts to leak" camp.

You should probably have a back-up or two just in case, I'm sure Dan would be happy to help there.

I don't think it would be something that it would ever need. I expect the material to lose its waterproofness before the seam sealer...

That said, a good seam sealer is half 100% GE silicone (caulk) and half odorless mineral spirits.

So far I have got ten years on my CCS tarp with no need to reseal it.

+1. Mine performed great in the rain before seam sealing.

One of CCS tarps is over five years old, and if I remember correctly, the other one is at least seven years old. I have had zero problems with either one of them leaking anywhere.
Neither of them have ever had a seam seal " touched up" and they won't get a touch up unless a seam start leaking.

Great tarps!

Many tarps don't leak whether they've been sealed or not. My (purchased) 10 x 10 has never been sealed, and has never leaked. I seal the tarps that I make just cause I don't trust my sewing.

I have never sealed mine.
