Hi everyone, hope this is the right forum for this question; I am preparing to install PVC cladding boards onto 3 walls of a shower. They are lightweight hollow PVC boards, a material similar to Correx but with a decorative face. They are 250mm wide and join together with a tongue and groove type edge joint. I have been told to use a bead of silicone in the joint for a waterproof seal, but it occurred to me that Solvent Weld might work to create a really permanent joint, effectively creating a single sheet. Has anyone tried this? I think it would work really well!
