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.

How to use Classi Seal

Step 1

Remove the backing paper 100mm at a time. Alight the top if the adhesive strip with the top edge of the shower tray or bath and firm press on by hand.

Step 2

Thoroughly rough and clean the sides of the tray or bath that the Classi Seal is to be attached.

Step 3

Manipulate and widen the upstand at corners. Upstand is easy to manipulate by hand to fit into irregular internal corners which are not square, so as not to interfere with the tiling.

Class 4

Tiling can begin immediately.

Following tiling or wall panelling, finish with a Neutral Cure Sanitary Grade 100% Silicone. Classi Seal prevents leakage from around shower trays and baths caused by the inevitable shrinkage and movement within buildings.

I recently changed the design of my bathroom and used Classi Seal to ensure my bath with an overhead shower was fully waterproofed. The bathroom retailer and my plumber both recommended I use Classi Seal in my project and I’m so glad I did. High quality product that does exactly...
