How does Classi Seal work?
Classi Seal when installed is never seen. It is purely preventative and as such is installed to the wall touching sides of the shower tray or bath prior to the being plumbed into final position. It waterproofs the ledge between the shower tray or bath and the wall. It is a flexible upstand applied to the tray or bath by hand using the butyl adhesive strip, simply remove the protective backing paper. Classi Seal is a secondary seal for when movement causes the primary silicone seal to fail, or if the silicone seal itself fails over time. It takes at most five minutes to install and is permanently flexible, allowing for future movement. Classi Seal is perfect if you are finishing with wall panels.
