Self-adhesive SBS elastomeric, easy peel foil faced membrane.

Product variations:
SELF-DAN AL 100 is a self-adhesive membrane manufactured with bituminous selected mastic modified with high performance SBS polymers, this will provide self-healing properties, easy application and great durability.r As a top layer it has a an aluminum foil of 60/1000 mm natural color. At the bottom side it has a releasable film.

Advantages & Benefits

  • As it is made of a bitumen mastic modified with SBS type elastomeric polymers that substantially improves the rest of bituminous mastics, it provides much better performance in terms of behaviour at high and low temperatures, elasticity and resistance to ageing, which leads to an improvement in the durability of the sheet and the safety of the waterproofing membrane.
  • It is self-adhesive and does not require the use of a blowtorch.
  • Excellent bonding.
  • Easy to install.
  • High resistance to weathering.
  • Total impermeability to water, water vapour and Radon gas.
  • Allows for adaptation to any type of geometry.
  • UV resistant.
  • Total flexibility of the material for perfect adaptation to the support.

Instruction for Use

Preparation of the substrate:
  • The surface of the base substrate must be resistant, uniform, smooth, clean, dry and free of foreign bodies.
  • A bituminous primer (Curidán, Impridán 100, Maxdán or Maxdán Caucho) must be applied beforehand.
  • The rolls are preferably laid parallel to the line of maximum slope.
  • The adhesion of the film to the substrate is achieved by removing the film from the underside and at the same time pressing with a blunt scraper or with gloves, from the inside outwards to avoid the formation of pockets. The overlaps must be made in the same way from roll to roll, and shall be 6 cm in the longitudinal direction and 8 cm in the transversal direction.
  • For easier installation, it may sometimes be necessary to cut the rolls into smaller, more manageable dimensions.

Indications and Important Recommendations

  • It should be kept in the sun for as short a time as possible to protect it from UV rays.
  • In case of new construction and renovation, possible chemical incompatibilities with APP plastomer-modified bitumen sheets shall be taken into account.
  • In case of renovation, chemical incompatibilities with old waterproofing consisting of flexible PVC sheets, modified tar-based mastics or any other, shall be taken into account, and it may be necessary to remove them completely or to use suitable separating layers (geotextiles, mortar layer, polyethylene film, etc).
  • If it is necessary to adhere to metallic or slightly porous elements, a bituminous primer (IMPRIDAN 100) must be applied to the entire surface to be bonded beforehand.
  • On flat roofs, it cannot be used as a waterproofing system.
  • On roofs, do not use on thermal insulation.
  • In cold weather, it is advisable to slightly heat the support with the blowtorch.
  • This product may form part of a waterproofing system, so all the documents referred to in the Danosa Solutions Manual must be taken into account, as well as all the regulations and legislation that must be complied with in this respect.
  • Exposure to the sun can make it difficult to remove the release film. The temperature of the sheet during installation must not exceed 50ºC.
  • NOTE: For more information on the Danosa systems in which this product is used, please see the document "Waterproofing Solutions".
  • It must not be installed when the ambient, product or substrate temperature is below +10°C.
  • There is no chemical incompatibility between the Danosa range of oxyasphalt, SBS elastomeric bitumen and plastomeric bitumen sheets.
  • Do not use as a top sheet on green roofs.
  • Do not use on roofs that are subsequently to be covered with heavy protection, be it paving, gravel or topsoil (in case of green roofs), or any other type of protection.
  • Do not use for waterproofing buried walls.
  • For ease of installation, it is recommended to cut the rolls into smaller, more manageable dimensions.
  • It shall be stored in a dry place protected from rain, sun, heat and low temperatures.
  • Possible incompatibility between thermal insulation and waterproofing shall be checked.
  • Polyurethane foam shall not be sprayed directly on top of the waterproofing without the use of a suitable separating layer (geotextiles, mortar layers, polyethylene film, etc).
  • The use of a roller is recommended to apply more pressure on the tape and improve adhesion.
  • It is recommended to protect after installation.
  • On porous or not very homogeneous substrates, a bituminous primer (Curidan, Impridan 100, Maxdan or Maxdan Rubber) must be applied before application.

Maintenance Recommendations

  • Maintenance requirements for Danosa Roofing Products The following maintenance checks must be adhered to: - A general examination on the condition of the waterproofing and surrounding roof components. - An inspection of all functional roofing elements including skylights, outlets, upstands, penetrations and any other visible roofing components. - Clean outlets, drains, gutters and remove any debris from the roof. - Periodic removal of mildew, moss, herbs or any other kind of vegetation that has been accumulation on the waterproofing. - Periodic removal of possible sediments accumulated on the deck (silt, sledges, slate granules, etc) by occasional water accumulation. - Periodic removal of debris and small objects that may have accumulated on the roof. - Ensure surrounding structural elements are sound such as eaves, flashings, slate tiles and brickwork. - Ensure that the waterproofing is in good condition and there are no blisters, damage or separation. - Review the condition of the waterproofing (adherence to upstands, condition of overlaps, visual appearance, etc) and repair the defects observed. These operations must be carried out twice a year, preferably at the beginning of spring or autumn and must be increased in case of decks or valleys with zero falls. It is also necessary to perform additional maintenance depending on the type of roof, location and proximity of roofs to areas with trees or in areas with high levels of pollution.
