100% pure polyurea membrane for waterproofing and coating

The 100% pure polyurea TECNOCOAT P-2049 system was developed as a two-component, sprayable, aromatic coating suitable for waterproofing, protection and sealing in general. It's made up of two high reactive liquid components, isocyanates and amines, which are mixed together using specific spray equipment, to form an aromatic, continuous, seamless, high density, solid and elastic pure polyurea membrane, with high mechanical and chemical resistance qualities.

It has CE marking on the basis of a statement made DoP Declaration of Performance (DoP) conforms to the UE 305/2011 regulation. Declaration is available on demand.

In general, you should take the following factors:

  • repair the surface (fill in depressions, eliminate unevenness, eliminate any old waterproofing, etc.)
  • singular points preparation(perimeter, sinks / evacuations, expansion joints or structural)
  • clean up the surface or substrate, removing any dust, dirt, grease or efflorescence.
  • remove any silicone based products
  • 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
  • adhesion tests may be required for certain substrates
  • in general all surface preparation requires the removal of all grease, dirt loose and flaking materials prior to the application of TECNOCOAT P-2049
  • the pull off strength of the membrane on concrete is 362,594 psi (2,5 N/mm² / 2,5 MPa ). 
  • in case of doubt of all above, apply before in a restricted area and to check

The TECNOCOAT P-2049 pure 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 application 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 our epoxy resin mortar: mix (ratio of ±1:4) of epoxy resin PRIMER EP-1020 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 an open pore surface achieved by grit blasting, milling or sanding (to achieve a Concrete Surface Preparation index -CSP- 3 to 9 from ICRI Guide 03732, depending of the final use)
  • on old concretes, some acid etched is needed to open the pores for primer acceptance
  • 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 dual component polyurethane PRIMER PU-1050/PRIMER PUc-1050 or the epoxy PRIMER EP-1020 should be used, to promote adherence to the concrete surface, reduce the pinhole appearance, and absorption of moisture in the substrate ( please check the primers absorption capacity in the TDS )
  • apply the TECNOCOAT P-2049 pure polyurea coating.
  • application of the aliphatic resin TECNOTOP S-3000/2C/2CP/1C 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" (consult the TDS of these products before the  use)

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 PRIMER EP-1040 or PRIMER EPw-1070.
  • apply the TECNOCOAT P-2049 pure polyurea coating.
  • application of the aliphatic resin TECNOTOP S-3000/2C/2CP/1C, 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" (consult the TDS of these products before the  use)

Sheets substrate:

The existing sheet surfaces (bitumen, EPDM, PVC, asphalt ...) must not show surface areas raised or not in good condition. He withdrew in poor areas. 

  • rolled roofing of any type should be in good condition prior to application.
  • there shall be cleaned with water to complete evaporation.
  • remove and replace some sections if need be
  • next apply the required primer; in these cases of non-porous surfaces use the water-based epoxy PRIMER EPw-1070.
  • apply the TECNOCOAT P-2049 pure polyurea coating.
  • application of the aliphatic polyurethane resin TECNOTOP S-3000/2C/2CP/1C, 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" (consult the TDS of these products before the  use)

  • 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 thin layer (50-100 g/m²) of polyurethane resin PRIMER PU-1000
  • light spread SILICA SAND over the wet primer applied before
  • wait for the total driying
  • apply TECNOCOAT P-2049, TECNOCOAT CP-2049 or DESMOPOL(adding DESMOPLUS, using by roll, squeegee or trowel)
  • apply TECNOTOP S-3000/2C/2CP/1C, 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 data sheet TDS)

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

For the formation, it is necessary to mix the two initial liquid components, isocyanates and amines by our 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: ±75 ºC
  • Heater amines temperature:±70ºC
  • Hose temperature:±70 ºC
  • Pressure: 2.900 psi (200 bar)
  • Recommended Mixing chamber: GU-07008-1 or GU-07008-2

These temperature and pressure parameters have to be valued, ratified or be varied by the applicator, depending on the conditions of each climate zone, weather situation or as projection equipment specifications.
