Mapei Mapeband SA 100mm X 25m Roll Self Adhesive Butyl Waterproofing Tape

Mapei Mapeband SA 100mm X 25m Roll Self Adhesive Butyl Waterproofing Tape

Self-adhesive butyl tape with alkali-resistant, non-woven fabric for elastic waterproofing systems.

Where to Use

Mapeband SA is a self-adhesive butyl rubber tape used to waterproof fillets between horizontal and vertical surfaces on terraces, balconies and in bathrooms and showers. This tape is a complementary product for elastic waterproofing systems, such as those of the Mapelastic and Aquaflex Roof ranges, or such as Mapegum WPS.

Application Examples

• Waterproofing corners and fillets between floors and walls on terraces, balconies and in bathrooms.
• Sealing different types of material (bitumen membranes, metal, ceramic and cementitious screeds).
• Sealing small, hard-to-reach fillets such as those between window and door fittings, ledges and substrates.

Advantages

• Quick application.
• Easy to install.
• Versatile.
• Alkali-resistant.
• Excellent adhesion to any type of substrate.

Technical Characteristics

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.

Recommendations

• Do not use Mapeband SA on damp substrates.
• Do not use Mapeband SA to seal areas subjected to water pressure.
• Use Mapeband SA in combination with waterproofing systems such as Mapegum WPS or Aquaflex Roof or with products from the Mapelastic range.
• If applied on ceramic, treat the surface with a coat of Eco Prim Grip primer before applying Mapeband SA.
• When applying the product on bitumen membranes, treat surfaces beforehand with a coat of Primer for Aquaflex.
• Apply at a temperature between +5°C and +30°C.

Preparation of the Substrate

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 membrane, it must be perfectly clean and treated with a coat of Primer for Aquaflex. Apply Mapeband SA when the primer is touch dry.

Application of the Product

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.
