Product Description

Mapei Mapeband External Corner pieces are pre-formed corners in alkali-resistant rubber with polyester felt backing, for waterproof sealing at external (convex) corners in wet rooms, showers and bathrooms. Used with Mapei cementitious waterproofing systems and liquid membranes, the moulded shape guarantees a continuous, leak-free seal at the most awkward detail on the job, without folding or cutting flat tape.

Key benefits

  • Pre-formed for a perfect fit at external corners, no folding or origami with flat tape
  • Alkali-resistant rubber with felt edges for a strong bond into the membrane
  • Maintains waterproofing continuity with Mapeband tape runs
  • In-service temperature range from −30°C to +60°C
