Other sizes are available, but even after 10 years in the construction industry, I’ve never needed anything more than a 2-inch roll. There are visual ways to distinguish a laminated tape from a co-extruded one. But during our third week of exterior testing, there was a three-day heat wave with two days in the low 90s and a final day in the high 80s.

This kind of stretching is nearly impossible to do with a thick 17-mil tape. All true duct tape has a rubber-based adhesive, but each tape has its own adhesive recipe.

Part of our range of plastering and rendering supplies is the CATNIC self-adhesive scrim tape with fibreglass mesh. This means that when the cloth grid is added, it melts directly into the plastic, forming a single, fully bonded piece. In every strength test, Gorilla was stronger. The cloth grid (or scrim)—typically made of polyester or a cotton/polyester blend—decides the tape’s strength, flexibility, and tearability. It was extremely flexible and by far the easiest to wrap, but it was so floppy that it often flopped over on itself. Through our research, and backed up by our firsthand testing, we found that a good general use duct tape should be around 11 milli-inches (mil) thick, use a natural rubber-based adhesive, and be made using a co-extrusion process. In the five years since our original testing, we’ve continued to use and evaluate many of the tested duct tapes. Then we stood on the piece of wood and cranked the come-along until the tape broke.

The threads that run across the tape determine its tearability. Paper joint tape is exactly as the name says: long strips of paper, usually in rolls of 75 feet or more. During testing, we found that this negative outweighed the added strength of the really thick tapes, like the 17-mil Gorilla.
