Works just as it is supposed to.

Daughter used this to install a motorhome window.

Foam board adhered to concrete frost walls
Color: White
Pleasantly surprised by how well and how fast this works. I didn't use any mechanical fasteners and applied 2' x 8' foam boards to the inside perimeter of 4' high concrete frost walls. With a few exceptions, I didn't brace or support this walls, just ran 5 vertical beads of the Sika adhesive down the 2' dimension of the foam board and pressed into place. Walls weren't perfectly smooth but the adhesive still grabbed and held after 20 or 30 seconds. Temps were nearly ideal, 80* outside and the walls had been in the sun most of the day-not sure if this would be as fun @ much lower temps. I used almost one tube per two 2' x 8' sheets, so it doesn't go far but well worth the time and materials saved if you had to brace/support/wait for them to stick.

Great for Sealing my Shed
Color: White
Used this product to help air seal my shed. Was easy to work with and formed a strong bond on softwood and OSB. No problems with capping and using partial tubes at a later date. Good stuff.

Crawl space encapsulation
Color: White
I used this to help adhere and seal 20 mil. plastic to the inside walls of our foundation as part of the encapsulation process. I wouldn't rely on it to hold the plastic up on it's own and I used it along side butyl tape and I have no reason to think it will fail over time. Great product!

It seals, but doesn’t adhere enough to be called an adhesive.
Color: White
I would call this a sealant, not an adhesive. It sticks enough to make a water tight seal. But it doesn’t adhere well enough to support anything heavier than a silver dollar. To be clear, it doesn’t adhere well to HDPE/RESIN which it advertises it does.
