Well made and strong

Well packaged with near perfect rolls. Adheres to ice cold dry cement blocks vey well as well as poly sheeting. Width works very well for several projects. Whatever you use it for, I strongly recommend using a roller with moderate pressure or even a broad faced mallet with firm taps to secure the tape to the substrate. Do so before peeling off the top layer of tape for superior adhesive strength. The cleaner the substrate, the stronger the bond. Use sharp scissors to prevent stretching the tape when cutting. Hope this helps.

Useful Product

Initial purchase was for a very small project on the travel trailer. Later realized it will probably come in handy for other projects too so I'm glad to have it on hand.
