Review on 🧱 AP Products 017 90892 Aluminum Sikaflex 221 by Josh Maher

Sikaflex 221 is a miracle product. If you want something to be glued and sealed at the same time and you want that thing to never move again, then this is what you need. If there's a chance you'll ever need to take this thing off, think twice! To say that this material is difficult to remove is a gross understatement. It's virtually impossible to cut with a knife and forms an absolute bond with whatever you apply it to. It is very likely that you will ruin things if you try to remove Sikaflex 221. I have used this material to attach solar panels to vehicle roofs. After curing it is as strong as if I used screws. I have no doubts about its durability and it's waterproof. Years later I don't see any cracks or aging of the material. That's great.
