Classi Seal is a professional, patented waterproofing solution applied by hand to the wall facing sides of shower trays or baths prior to installation. The inherent flexibility of the product can accommodate 15mm of movement, making it equally suitable for new build, repair or renovation.
 
 
 
Classi Seal consists of a flexible upstand made from wthylene propylene diene monomer (EPDM) and is a modified butyl rubber adhesive. The EPDM is extruded with an integral antistretch glass fibre reinforcing strip. This aids speed and ease of fitting, and also allows for subsequent manipulation in the corners to assist with the tiling operation.
 
 
 
Classi Seal is supplied in a range of lengths and is used in an unbroken, continuous run.
