  • Sealing Performance: Durable, watertight barrier that resists mould and discolouration
  • Best for: Homeowners wanting a quick, tidy alternative to silicone caulk

Premium PVC forms a durable, anti-mould seal that resists discolouration. Self-adhesive backing creates an airtight bond for kitchen and bathroom joints.


Long-lasting, anti-mould seal - with premium PVC construction

High-quality PVC creates a continuous waterproof barrier that resists mould and discolouration while remaining non-toxic. Material stability helps maintain adhesion and appearance over time.

Sealed joints stay cleaner for longer, cutting down on frequent re-caulking and ongoing maintenance.

Fast, tidy installation - with self-adhesive backing and included sealing tool

Peel off the protective backing, press the tape firmly into place and smooth using the supplied scraper to form an airtight seal. Adhesive backing bonds directly to common bathroom surfaces.

A professional-looking finish is achievable in minutes, without specialist tools or wet silicone mess.

Fits corners and awkward joins - with linear crease and heat flexibility

Linear crease design allows the tape to bend neatly at 90 degrees for tight corner adhesion, and gentle heating with a hairdryer increases pliability in colder conditions.

Easier fitting around baths, sinks, worktops and camper windows, reducing gaps and uneven joins.
