Elongable polyurea membrane for waterproofing and coating

TECNOCOAT H-2049 EL is a two-component, sprayable, aromatic coating suitable for waterproofing, protection, and sealing. It's made up of two high reactive liquid components, isocyanates and resins, mixed using our specific spray equipment (TC2049) or similar, to form a solid, continuous, watertight and waterproof, seamless, high density and high elastic polyurea membrane, with high mechanical qualities, especially in elements with structural movements.



For waterproofing and protection of:

  • Metal roofs (zinc, copper...).
  • Construction element on civil works (bridges, beams, concrete decks, retaining walls, and foundations ...)
  • ROOFING: Sloped and flat roofs (walkable), balconies, and overhangs.
  • IRMA roofing system
  • Vehicle and boat coatings(bed liners)
  • Furniture and thematizations
  • Asbestos roofs rehabilitation (use with TECNOFOAM)
  • As a protection for an SPF (spray polyurethane foam TECNOFOAM)

  • TECNOCOAT H-2049 EL is a very elastic and hard-wearing product that, once applied, offers great stability and durability.
  • the application and training are done by our spray equipment TC2049 ( or similar
  • thanks to its versatility and its drying time of between 13 and 15 seconds TECNOCOAT H-2049 EL 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 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.
  • recommended consumption is approximately 1,7 kg/sqm (at 1,5 mm dry film thickness). This data could vary depending on the type of application, weather conditions, or substrates' nature.
  • 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's properties enable it to bond to any surface, such as cement, concrete, polyurethane, wood, metal, etc. 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)
  • his properties allow it to adhere to any surface such as concrete, ceramic tiles, metals, spray polyurethane foam (Tecnofoam), plywood, asphalt/bituminous sheets. In any case or material, the surface must be consistent, firm, clean, and dry when the products are applied. Recommended applying directly on the concrete deck. Ponding water admitted.
  • free from harmful VOC compounds, therefore, it does not hurt the ozone layer (VOC's zero). It's 100% recyclable by mechanical means friendly to the environment; no gas collection for recycling and/or destruction is required; it doesn´t emit substance to the environment once installed.
  • the system requires solar radiation protection (UV rays) to do not lose its physical and mechanical properties, given that it is an aromatic membrane. The system incorporates 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.



Metal drums of 225 kg each component (B side: resins and A side: isocyanates).


12 months at temperatures between 5°C to 35°C, provided it is stored in a dry place, keep away from direct sunlight, extreme heat, cold, or moisture. Once the tin has been opened, the product must be used. Once opening drum, B side must be agitated mechanically before inserting the transfer pumps and use.


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

  • repair the surface (fill in depressions, eliminate unevenness, eliminate any old waterproofing, etc.).
  • 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 is >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 H-2049 EL elongable and 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 latencies or release agents should be eliminated and open the pore surface achieved by grit blasting, milling, or sanding.
  • next, clean 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 dual-component polyurethane PRIMER PU-1050 should be used.
  • application of the TECNOCOAT H-2049 EL polyurea membrane.
  • application of the aliphatic polyurethane resin TECNOTOP S-3000/2C/2CP, in consumption and desired thicknesses in the case of no protection against UV rays. 

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.
  • application of the TECNOCOAT H-2049 EL polyurea membrane.
  • application of the aliphatic polyurethane resin TECNOTOP S-3000/2C/2CP, in consumption and desired thicknesses in the case of no protection against UV rays. 


  • Consult in all cases the waiting times, drying time, singular points treatment, conditions of application of all the products through the technical data sheets of each product, the technical handbook of application of TECNOCOAT, or consult our technical department.
  • For other types of supports/substrates, for further information on the execution application procedure, for any additional questions, please, consult the technical data sheets (TDS) of these products, or our technical department.
  • These guidelines are valid although they can be modified, according to the situation of the supports, conditioning of the bearing structures of the elements to be waterproofed, external climatology, or situation at the time of application


In cases where the membrane repair by accidental causes, or assembly procedures not covered installations, shall be as follows:

  • cut, removal of the affected area and/or damaged surface
  • sanding this area extending about 20~30 cm. around the perimeter, for overlapping security
  • cleaning (vacuuming) of waste generated (powder, dust...); if it's possible don't use water, and if used, support humidity value; ketones applicability based solvents for reducing this type of surface cleaning
  • apply a thin layer (100-150 g/sqm) of polyurethane resin PRIMER PU-1050, PRIMER EPw-1070
  • light spread SILICA SAND over the wet primer applied before
  • wait for the total drying
  • apply TECNOCOAT H-2049 EL
  • apply TECNOTOP S-3000/2C/2CP, in consumption and desired thicknesses in the case of no protection against UV rays. 

In cases has been exceeded recoat time (24~48 hours), so the waiting time between jobs is prolonged, proceed as follows:

  • sanding strip longitudinal overlap of about 20~30 cm. wide
  • cleaning (vacuuming) of waste generated (powder, dust...)or existing dust; if it's possible, do not use water, and if it's used, check the support humidity value; ketones applicability based solvents for conducting this type of surface cleaning
  • apply a thin layer (100-150 g/sqm) of polyurethane resin PRIMER PU-1050, PRIMER EPw-1070
  • light spread SILICA SAND over the wet primer applied before
  • wait for the total drying
  • apply TECNOCOAT H-2049 EL
  • apply TECNOTOP S-3000/2C/2CP, in consumption and desired thicknesses in the case of no protection against UV rays. 


For the formation, it is necessary to mix the two initial liquid components, isocyanates and amines by our spray equipment TC2049 ( or similar (proper maintenance and cleaning it is recommended). The general parameters for this material will be the following:

  • Heater isocyanate temperature: 70-75 ºC
  • Heater amines temperature:70-75ºC
  • Hose temperature:±70 ºC
  • Working pressure: 2.500 - 3.000 psi
  • Recommended mixing chamber: GU-07008-1/GU-07008-2

Anyway, these parameters for adjusting the projection equipment are approximate and may change depending on the weather conditions of the environment at the moment to apply, therefore, it is the responsibility of the applicator values in each case the option to choose.
