rivets, screws, hot melt, contact cement, tie raps, bailing wire, fishing line, tarp tape...

I've needed something like tarp tape at least a dozen times before but have never seen it on the shelves.

I'm feeling good today, have a tarp tape day.

Its best to activate the surface before sticking on tarp tape...I use a propane torch.

In order to glue one piece of Coro to another, CA glue may be used. Unfortunately, it is not enough just to apply some glue to the parts to be bonded. By nature, the plastic used for making Coro does not bond well unless its surface is first "activated". A common technique for achieving this is called 'flashing'. This involves passing a flame over the surface for just a moment, being careful not to melt the surface. A hand-held torch seems to work well for this task and can be purchased for under $15 from your local hardware store. Test your technique on a scrap piece first. Water should not form droplets, but a thin film on properly activated Coro.

I bought a propane torch recently and did not see why I should pay fifty percent more for one that lit itself, I had just bought a barbecue lighter.

The barbecue lighter ran out long before the torch did and hopefully an integrated system would be easier to light.

Couple years ago the Coroplast company website recommended silicone caulk. I have had excellent results from any 3M product I used personally or professionally.
