Classi Seal Upstand Waterproof Tape

Are you looking to completely waterproof a shower tray or bath installation? The Classi Seal waterproof tape is the industry-leading solution designed to permanently stop leaks before they happen. This highly flexible waterproof upstand acts as a permanent secondary seal, providing ultimate peace of mind for both DIYers and professional tradespeople.

Unlike standard silicone that can degrade or crack over time due to natural building settlement, the Classi Seal roll accommodates structural movement of up to 15mm. By wrapping this durable shower tray waterproofing tape around the edges of your fixture before tiling or applying wall panels, you create an impenetrable, long-lasting barrier against water damage.

Figuring out how to fit Classi Seal is incredibly straightforward. The tape features a strong self-adhesive backing that securely bonds directly to the side of your shower tray or bath edge. Once applied, it bridges the vulnerable gap between the wall and the tray, ensuring that any water penetrating the grout lines is safely directed back into the basin. This makes it a vastly superior bath sealing tape for preventing costly water damage to the floors and ceilings below.

Whether you are tackling a compact bathroom renovation or outfitting a large ensuite, you can easily buy Classi Seal in the exact size your project demands. The tape is available in multiple lengths, ensuring a perfect, continuous fit with zero corner joints. Protect your home and ensure a permanent watertight finish today.
