Mapei Mapeband is a rubber tape with alkali-resistant fabric for cementitious waterproofing systems.
Mapei Mapeband is used for:
• Waterproofing corners between adjacent walls and between walls and floors before treating with Mapelastic or Mapelastic Smart.
• Flexible waterproofing of expansion joints on terraces and balconies, etc. before treating with Mapelastic or Mapelastic Smart.
• Sealing pipes and drains in bathrooms, showers and kitchens in conjunction with Mapeband gaskets.
• Sealing expansion joints in precast panels.
Mapei Mapeband is a vapour and water-resistant rubber tape with fabric edging which is resistant to alkali. It is elastic and deformable even at low temperatures with excellent resistance to adverse weather conditions.
Mapei Mapeband is resistant to alkalis, acids and salt solutions (for special cases, test before using).
Mapei Mapeband Waterproofing Tape is also available in ready-made internal and external corner sections along with a 400mm x 400mm gasket for pipes in bathrooms, kitchens, showers, etc.
• For perfect sealing on corners use Mapei Mapeband 90° and 270° special corner pieces.
• For perfect sealing on pipes use the 400mm x 400mm Mapei Mapeband gasket.
• In correspondence with T or cross joints, use the special T or Cross profiles.
Apply a thin layer of Mapelastic or Mapelastic Smart, at least 1 mm thick, to the sides of the corners and expansion joints to be waterproofed.
Apply the fabric side of the Mapei Mapeband or special pieces over the fresh layer of Mapelastic or Mapelastic Smart, using a smooth trowel.
It is essential that Mapelastic or Mapelastic Smart wet both sides of the band, also the rubber tape, for a width of several mm. For movement joints (i.e. in terraces) Mapei Mapeband must be positioned in the shape of an omega Ω (see datasheet): The tape can then be subjected to tension.
Joints between strips must be sealed with Adesilex T, Adesilex T Super or Adesilex LP.
