It is a stable bituminous emulsion in dark brown colour and doughy consistency. Composed of tiny bituminous particles in a water solution with an emulsifying agent. The latter contains certain SBS products that confer the MAXDAN CAUCHO dry film a perfect adherence, flexibility and elasticity.It complies with the specifications required by UNE 104-231/88.It is used for protection of walls, separating walls and foundations, deposits, etc., as well as vapour barrier. Can also be used for repairing old waterproofing systems.

Scope

  • Adhesive of thermal insulation panels (cork or similar).
  • Vapour barrier (approximate total yield (2 kg/m²).
  • In the case of sloping roofs with CURIDAN ASPHALTIC PLATE, the first row of plate is not only nailed to the substrate, but also bonded to it with MAXDAN RUBBER.
  • In the case of renovating old, self-protected bituminous waterproofing with slate or mineral granules, it can be used as a primer before applying the new bituminous waterproofing system. In bonded systems, the bituminous sheet is welded in its entirety, so the entire surface must be primed. In non-bonded or floating systems, the bituminous sheet is only welded at the singular points (parapets, drains, expansion joints, etc.), and these elements must be primed.
  • Primer and preparation of surfaces where a bituminous sheet is to be welded, on both porous and non-porous surfaces.
  • Priming and preparation of porous surfaces that will later be waterproofed or treated with asphalt products.
  • Protection from dampness in walls and partition walls.
  • Dampness protection of the outer underside of abutments and wings of viaducts and overpasses of roads, railways, avenues, etc.
  • Dampness protection of the external surface of concrete retaining walls and buried foundations, acting on the side in contact with the ground.
  • Dampness protection of the outer surface of subways and service tunnels in civil engineering works.

Advantages & Benefits

  • Good adhesion on porous materials.
  • Good durability.
  • Good chemical resistance to saline water and weak acids and even weak bases.
  • Doughy consistency.
  • Asphalt mortars are less rigid and more plastic than conventional mortars.
  • A paste-like product with a uniform appearance and cold application that hardens by evaporation of the water it contains. Once applied and dried, it forms a continuous film.
  • Little thermal variation.
  • Easy application.
  • Great bonding.
  • Insoluble once the film dries.
  • Asphalt mortars have the advantage over conventional mortars in that they put less stress on bituminous waterproofing.
  • It does not crack in the cold, nor does it flow in the heat.
  • Chemical resistance.
  • Waterproof.
  • It can be applied with a brush, paintbrush or roller.
  • It can be applied in closed rooms.
  • It can be applied on wood, concrete blocks, masonry, mortar, bricks, lightened concrete, etc.
  • Totally stable and long lasting.
  • Solvent free.

Support

  • Plasticised and self-protected asphalt sheets.
  • Compatible thermal insulation products.
  • Concrete subsrates.
  • Wooden subsrates.

Instruction for Use


Instruction for UseThe substrate must be clean of dust, grease, paint residues, plaster and foreign bodies. Loose or poorly adhered particles must be removed, so it is recommended to clean the surface to be treated. Cracks and roughness shall be filled with MAXDAN CAUCHO, avoiding gaps or voids that may break the bituminous film once it has been formed. If necessary, the surface shall be regularised with a properly trowelled mortar.Type of substrate: MAXDAN CAUCHO should not be applied on polished surfaces as adhesion failures may occur.Substrate moisture: MAXDAN can be applied on dry or damp surfaces, but without water run-off. When dealing with very absorbent surfaces or with applications in hot weather and under sun exposure, it is advisable to water the surface to avoid a quick absorption or evaporation of the water in the emulsion, which could cause cracking in the bituminous film.Drying time: It depends on the ambient temperature, sun exposure and relative humidity. The minimum recommended time between coats is about 24 hours.
  • Protection against humidity of the external surface of concrete retaining walls and buried foundations. A first coat of primer is applied with MAXDAN (see application as a primer coat). Subsequently, at least two more coats must be applied, crosswise, also with MAXDAN. The approximate coverage of each coat is 0.5 kg/m2. Before applying one coat, check that the previous one is completely dry.
  • Protection against damp in walls and party walls. Proceed as described in the previous section.
  • Priming and preparation of porous surfaces where a bituminous sheet is to be subsequently welded. Apply a coat of MAXDAN, diluted with water in a proportion of approximately 10-20%, making sure that the pores are well impregnated. The approximate yield will be 0.3-0.5 kg/m². In adhered systems, the bituminous sheet is welded in its entirety, so the entire surface must be primed. In non-bonded or floating systems, the bituminous sheet is only welded in the singular points (parapets, drains, expansion joints, etc…), and these elements must be primed.
  • Priming and preparation of porous surfaces that are subsequently to be waterproofed or treated with asphalt products. Apply a coat of MAXDAN, diluted with water in a proportion of approximately 10-20%, making sure that the pores are well impregnated. The approximate yield will be 0.3-0.5 Kg/m².
  • Restoration of old self-protected bituminous waterproofing with slate or mineral granules. Once the self-protected sheet has been swept and cleaned, MAXDAN shall be applied as described in the previous section. Subsequently, the new bituminous waterproofing system shall be applied. In adhered systems, the bituminous sheet is welded in its entirety, so the entire surface must be primed. In non-bonded or floating systems, the bituminous sheet is only welded at the singular points (parapets, drains, expansion joints, etc.), and these elements must be primed.
  • Adhesive for thermal insulation panels (cork or similar). Once the substrate and the surface of the material to be adhered have been primed, MAXDAN CAUCHO should be applied undiluted to the insulation panels, over the entire surface, using a trowel or spatula. Wait a few minutes before pressing the panels onto the substrate. The approximate yield is 1-2 kg/m² depending on the roughness of the substrate. If the thermal insulation board is to be installed on the ceiling, mechanical fasteners must also be used.
  • pour barrier: A first coat of primer is applied with MAXDAN CAUCHO (see application as primer coat). Subsequently, at least two more coats of MAXDAN CAUCHO must be applied, crosswise to each other. The approximate coverage of each coat should be 1.0 kg/m², providing a minimum total thickness for this specific use of 2.0 kg/m². Before applying a coat, check that the previous coat is completely dry.


Indications and Important Recommendations

  • Before using the product, stir well until it is perfectly equal.
  • In case of refurbishment, chemical incompatibilities with old waterproofing systems consisting of PVC membranes, 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.
  • 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.
