No, didnít seal anything. I covered the frame with backer board and applied the adhesive to the Air Stone and stuck it onto the backer board. It held for a couple of years before the Air Stone started to fall off. The adhesive stuck pretty well to the backer board but didnít stick worth a damn on the Air Stone.

In an effort to save the project I reattached the belligerent Air Stones with Liquid Nails and I had pretty good luck with that. But then more and more of the other Air Stones started coming off and I simply had enough of the whole affair and pulled them all off.

BTW, the Air Stones that I had reattached with Liquid Nails were holding well and were a little more difficult to remove. In short, the junk that Air Stone suggested we use was just thatÖ junk.
