Classi Kit Trays&Baths 8.2M B

Classi Waterproofing Kit for Shower Trays and Baths is used to waterproof the entire showering area.

The majority of water leaks in showering areas occur between the ledge of the shower tray or bath and the wall. However water can also get through cracks high above the bottom ledge in cracks in the grout between tiles and in the corners. Classi Waterproofing Kit for shower trays and baths is a belts and braces waterproofing product.

First Classi Plus is applied to the wall touching sides of the shower tray or bath. This is then bonded to the wall with tile adhesive. Tile adhesive is then applied in front of the upstand and up the wall, to which the Classi waterproofing membrane is pushed into. Excess air is removed and the process is repeated until the showering area has been covered with membrane. Special corner and joint tape is used in the corners and also for overlapping sheets of waterproofing membrane. Where the water pipes go through the membrane pipe collars are supplied to fit over the pipes. The process takes approximately 1 hour and after this tiling can begin in the normal way.
