It's very sticky, be careful to only stick it where you want it. Backing tape is a bit tricky to remove, but once it's placed, it's solid.

Used for flushing around new window installation. Product is very sticky but not so stretchable. So, you have to do some overlap around corners.

I just installed 30 windows and 2 doors with this product. It sticks well even in 20 degree Temps.Not cheap but, neither is fixing a leaking window later on.I recommend this product along with Dupont flex wrap for the pan flashing, even though the flex wrap dosent stick as well in cold without the use of a heat gun

It’s a good product.The rubber can’t be stretched around corners due to foil - rubber bondage

This si the real deal. make absolutely sure you have this tape in place where you want it before removing the backing piece. You can remove it from plywood, but it pulls up a bunch of fibers. It sticks to itself and is almost impossible to pull apart. The is the perfect item for closing flashing around windows
