I was making a concrete table top with the state of Texas inlay. I was using the Gorilla Glue to hold the river rocks in place while I poured the concrete into the form. After the concrete had cured, I was removing the form piece by piece. When it came time to flip the concrete over to remove the bottom board, it would not come off. I tilted the form onto its side so the weight (400 lbs) would free it from its bond. Not happening. Then, I used a dolly to get between the form and the slab to pry it up. I might add that I used just a drop on each rock to keep them in place! After seeing this with my own eyes, I am definitely a firm believer in the strength of Gorilla Glue.
