TECNOCOAT CP-2049 PLUS

Cold polyurea membrane for waterproofing and coating

The cold polyurea TECNOCOAT CP-2049 PLUS is a two-component polyurea, that once applied, forms a continuous, solid, 100% waterproof membrane without joints or overlaps and completely adhered to support. Suitable for waterproofing, protection, and sealing in general. Due to its cold and manual application, is ideal too for repair or recoating on top of our polyurea membranes range, once these are already cured.

It has a CE marking on the basis of a statement made DoP Declaration of Performance (DoP) conforms to the EAD  030350-00-0402. (ETA 20/0253), at 1,2 mm thickness and 25 years or estimated working life.

GENERAL FEATURES:

  • TECNOCOAT CP-2049 PLUS is a very strong and hard-wearing membrane that, once applied, offers great stability, durability, and a perfect waterproofing and seal
  • Thanks to its versatility and its drying time of between 20~25 minutes TECNOCOAT CP-2049 PLUS adapts to any surface, making it the ideal product for application on uneven surfaces and in areas of any shape, whether curved or squared.
  • it holds an ETA 20/0253 specific approval for "Liquid Applied Roof Waterproofing Kit for roofing, based on polyurea" working life 25 years ( W3) with a minimum thickness of 1,2 mm, issued by EOTA (European Organization for Technical Assessment) under an EAD 030350-00-0402; always consult our technical department or check our Technical Guidelines, depending on scope or use.
  • TECNOCOAT CP-2049 PLUS system's properties enable it to bond to any surface, such as concrete, ceramic tiles, polyurethane foam, wood, metals, bituminous sheets, acrylic paints
  • 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)
  • Applying TECNOCOAT CP-2049 PLUS 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.
  • The application method is by the squeegee, trowel or roll,  or electrical machine (relation 3:1)
  • It doesn't create bubbles in any thickness. The recommended total thickness is 1,5 mm. (80 mils DFT), consumption 2,40 kg/sqm)
  • TECNOCOAT CP-2049 PLUS polyurea membrane system 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 where the maximum humidity ranges are specified or our Technical Application Manual for TECNOCOAT CP-2049 PLUS.
  • TECNOCOAT CP-2049 PLUS system requires solar radiation protection (UV rays) to ensure it does not lose its physical and mechanical properties, given that it is an aromatic membrane. So you have to apply our polyurethane-colored aliphatic resin, TECNOTOP 2C/2CP, for use in the absence of other physical protection elements.

APPLICATION METHOD

In general, the following aspects should be dealt with prior to application:

  • repair the surface (fill in depressions, eliminate unevenness, eliminate any old waterproofing, etc.)
  • singular points preparation(perimeter, sinks / evacuations, expansion joints or structural)
  • the surface has to be enough compressive strength of adhesion of the membrane. If it were not so, we will proceed to apply our primers resins to achieve this target
  • the pull-off strength of the membrane will be minimal 1, 5 MPa
  • clean up the surface or substrate, removing any dust, dirt, grease, or efflorescence.
  • in case of doubt of all above, apply before in a restricted area and to check

The TECNOCOAT CP-2049 PLUS polyurea system can be applied to many different surfaces and the procedure will vary depending on its nature or state.

Below we set out some of the applications for the most common surfaces; for other surfaces not described, please contact 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 in the conditions and with the parameters indicated in the technical specifications for these products. In general, the two-component polyurethane PRIMER PU-1050 should be used.
  • roll or squeeze application of the TECNOCOAT CP-2049 PLUS 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 or electrical equipment(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 prior priming using a 100% solids epoxy resin PRIMER EP-1040 or water-based epoxy resin PRIMER EPw-1070, to improve surface leveling and bonding. Consult the technical specifications of this product.

HANDLING

These safety recommendations for handling, are necessary for the implementation process as well as in the pre and post, on exposure to the loading machinery.

  • Respiratory Protection: When handling or spraying use an air-purifying respirator.
  • Skin protection: Use rubber gloves, remove them immediately after contamination. Wear clean body-covering. Wash thoroughly with soap and water after work and before eating, drinking, or smoking.
  • Eye / Face: Wear safety goggles to prevent splashing and exposure to particles in the air.
  • Waste: Waste generation should be avoided or minimized. Incinerate under controlled conditions in accordance with local laws and national regulations.

Anyway, consult the material and safety data sheet of the product.
