Concrete Edge Form Liner - 3" Rough Rock

Not quite perfect

These edge forms are tough, cast a great surface and are reusable many times. However, they could be better in two ways. First, the pattern does not continue from one form to the next. It would be nice if they could be connected without a break in the pattern. Second, nothing sticks to these forms, not even hot glue. This makes it difficult to set them up. I know that for straight edges, you could put straight form strips to back up these forms, but for a curved slab, I need to glue backers to the forms themselves. It's difficult when the glue doesn't stick.
