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.

Easy to place between a new ledger board and the siding on my home. Sticks well and comes off the roll without difficulty.

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
