GENERAL FEATURES:

  • TECNOCOAT CP-2049 is a very strong and hard-wearing membrane that, once applied, offers great stability, durability, and a perfect waterproofing and seal.
  • it holds an ETA 20/0253, issued by EOTA (European Organization for Technical Assessment). under the EAD 030350-00-0402 guide, specific approval for "Liquid Applied Roof Waterproofing Kit, based on pure polyurea" working life 25 years ( W3), at 1.2 mm thickness, ponding water admitted
  • The application method is by the squeegee, trowel or roll, (do not apply with the airless machine)
  • Thanks to its versatility and its drying time of between 20~25 minutes TECNOCOAT CP-2049 adapts to any surface, making it the ideal product for application on uneven surfaces and in areas of any shape, whether curved or squared.
  • The TECNOCOAT CP-2049 system's properties enable it to bond to any surface, such as concrete, ceramic tiles, polyurethane foam, wood, metals, bituminous sheets, acrylic paints
  • Applying TECNOCOAT CP-2049 saves in seals and any other kind of joins, as the finish is uniform and makes up a single layer, providing a surface with optimum maintenance and cleaning properties.
  • it should be applied in dry conditions avoiding the presence of humidity or coming from the surface to be coated or the substrate, whether at the time of application or subsequently (pressure from phreatic water level). In the event there is humidity in the substrate at the time of application, consult the technical specifications of our primers in the TDS
  • the system requires solar radiation protection (UV rays) to do not lose its physical and mechanical properties, given that it is an aromatic membrane is necessary to apply a protective polyurethane colored aliphatic resin, Tecnotop 2C, for use in the absence of other physical protection elements. You can apply too Tecnotop S-3000, Tecnotop 2CP or Tecnotop 1C.
  • USe Desmothix on vertical and sloped surfaces
  • Furthermore, due to its resistance, it can be walked on and it will accept a rough finish to make it non-slip (according to ENV 12633:2003)
  • Ceramic flooring can be placed on top. In this case, we recommended spreading a well-distributed load of Silica Sand to improve mechanical anchorage, or if it has already catalyzed, spreading a layer of PRIMER PU-1050 (100-120 g/sqm), for anchoring the Silica Sand

THICKNESS AND RECOMMENDED YIELD

The recommended minimum thickness is up to 1,5 mm, so the yield will be up to 2,3 kg/sqm (DFT) applied on only one coat. this consumptions may vary according to the substrate conditions and climate.

APPLICATION METHOD

In general, you should take the following factors:

  • Surface reparation ( fill the cracks and fissures, remove old existing waterproofing paints...).
  • Clean up the surface, removing dust, oils and grasses,  and existing chippings.
  • Support will be strong and dry.
  • The supports must be firm and dry. No moisture or humidity inside or by capillarity from the backfill.

You can apply Tecnocoat CP-2049  over several supports and materials. Below we set out some of the applications for the most common surfaces; for other surfaces not described, please call our technical department.

Concrete substrate

  • any depressions or voids should be repaired using a mix (ratio of ±1:4) of our epoxy resin PRIMER EP-1020  mixed with silica sand.
  • the concrete should be completely cured (concrete curing takes 28 days) or, in any case, the maximum level of humidity allowed for the substrate should be verified, depending on the primer used.
  • any concrete laitance or release agents should be eliminated and an open-pore surface achieved by grit blasting, milling, or sanding.
  • next, clean up and eliminate all contaminants from the elements, such as dust or particles from the previous processes.
  • apply the primer resin in the conditions and the parameters indicated in the technical specifications for these products. On concrete, we recommended the two-component resins PRIMER PU-1050 / PRIMER PU-1000 / PRIMER PUc-1050 / PRIMER EP-1010. See the TDS of each product before the application
  • roll or squeeze application of the TECNOCOAT CP-2049 pure polyurea membrane.
  • application of the polyurethane resin TECNOTOP 2C, in consumption and desired thicknesses in the case of no protection against UV rays. This application can be done by short hair roller type equipment "airless" (see the conditions of application in the product datasheet TDS)

Metal substrate

  • metal surfaces should be prepared using sand-blasting, in order to improve the surface's mechanical fixation properties.
  • check the seals and overlaps and where necessary seal with MASTIC PU mastic or TECNOBAND 100, in combination.
  • for rapid and efficient cleaning of the surface using a ketone-based solvent.

  • apply the TECNOCOAT CP-2049 polyurea membrane.
  • apply TECNOTOP 2C  to protect the membrane from the UV rays

Ceramic substrate

  • ceramic surfaces should not have empty joints or loose elements or parts. These should be filled with MASTIC PU mastic, complemented with TECNOBAND 100 on the joints if necessary.
  • for rapid and efficient cleaning of the surface use pressurized water and check that it evaporates completely. Also, verify that all dust and other physical contaminants have been eliminated.
  • next, apply the required primer; in these cases of non-porous surfaces use the water-based epoxy PRIMER EPw-1070.
  • apply the TECNOCOAT CP-2049 polyurea membrane.
  • apply TECNOTOP 2C  to protect the membrane from the UV rays

Sheets substrate
