Features & Benefits

• Quick application
• Easy to install
• Versatile
• Alkali-resistant
• Excellent adhesion to any type of substrate
• Mapeband SA is a self-adhesive tape made from butyl rubber with alkali-resistant, non-woven polypropylene fabric bonded on the outer surface that guarantees excellent adhesion for the waterproofing system to be applied over it
• Mapeband SA adheres to various types of non-absorbent substrates such as aluminium, copper, steel, plastic, bitumen waterproofing membranes, ceramic and to absorbent substrates such as concrete, masonry, aerated concrete, fibre-reinforced cement and render

Preparation

• Surfaces on which Mapeband SA is to be applied must be well-cured, sound, clean and dry and must be free of all traces of oil, grease, cement laitance and any other product or substance that could prevent the adhesive tape from adhering fully
• Mapeband SA may be applied on concrete, solid and perforated bricks and concrete blocks as long as they have no sharp corners or rough edges
• If surfaces need to be skimmed, use a product from MAPEI’s Planitop or Mapegrout ranges
• On crumbly or dusty screeds, consolidate the surface with MAPEI Primer 3296 before applying Mapeband SA
• Consumption varies from 0.1 to 0.5 kg/m², depending on the absorption and porosity of the surface to be treated
• For existing ceramic floors, on the other hand, the surface must be treated with MAPEI Eco Prim Grip before applying Mapeband SA. If Mapeband SA needs to be applied on a bitumen membranes, it must be perfectly clean and treated with a coat of Primer for Aquaflex
• Apply Mapeband SA when the primer is touch dry

Application

• Unroll Mapeband SA, place it on a solid base and trim to the length required with a cutter
• Place Mapeband SA at the start of the fillet to be waterproofed and partially remove one of the two sides of the protective film
• Press down on the tape from the centre towards the edges to help it adhere and to prevent creases forming and air bubbles remaining under the tape
• Remove the remaining protective film to complete application of the strip of Mapeband SA
• Joints between strips of tape must overlap by at least 5 cm
• Once all the tape has been applied, go over the entire surface with a rubber roller to make sure it is well adhered
• To finish, waterproof the substrate with a product from the Mapelastic range, Mapegum WPS or Aquaflex Roof
