Drybase 75mm x 20m Overseal Tape for Plaster Mesh Membrane

Drybase 75 mm Overseal Tape is a one-sided waterproof butyl tape used for sealing overlaps, butt joints and perimeter connections between cavity drainage membranes. Designed for compatibility with both floor and wall applications, it helps form a strong, continuous seal across membrane junctions to enhance damp protection performance. The tape is flexible, long lasting and easy to cut with standard tools, making it a practical choice for detailing around pipes, corners or changes in direction. Each roll measures 75 mm in width, 1.5 mm in thickness and 20 metres in length, providing extensive coverage for typical domestic and commercial use cases.
