ARDEX STB Self Adhesive Butynol® Tape is an uncured Butynol® tape with a fleece layer that provides a waterproofing seal between the surface joints and between the floor and wall, under shower plates and seals the drainage pipe outlets in wet areas such as bathrooms, kitchens, laundries and balconies.
 
This tape is 1mm thick and allows the membranes to be applied at the correct thickness and so perform in accordance with the waterproofing standards. STB Tape can be used in conjunction with ARDEX Waterproofing products.
