Hi all, I’ve installed a hydra pools 20x40 lagoon with a tanning ledge. The stairs have a groove made into each section on the back of each tread and the bottom around the wall of the tanning ledge for the bead made to the liner to secure into to hold in place. How in the world do you get that liner bead to push down into that groove? They sent some plastic tools to push with but it’s not very productive. Any tricks I’m missing here? Thanks for any help!
