TECNOCOAT P-2049 LV

Low viscosity polyurea membrane 100% pure for waterproofing and coating

The 100% pure polyurea TECNOCOAT P-2049 LV membrane was developed as a coating suitable for waterproofing, protection and sealing in general. The pure polyurea TECNOCOAT P-2049 LV membrane is made up of two high reactive liquid components, isocyanates and amines, which are mixed together using spray equipment (TC2049 http://spray-equipment.tecnopolgroup.com/), to form an aromatic, continuous, without joints, high density, solid and elastic pure polyurea, for protecting the polyurethane foam TECNOFOAM (SPF)

GENERAL FEATURES

  • TECNOCOAT P-2049 LV is a very strong and hard-wearing product that, once applied, offers great stability and durability.

  • the properties of the TECNOCOAT P-2049 LV system allow it to adhere to any surface such as concrete, ceramic tiles, metals, 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.
  • the application and training are done by our spray equipment TC2049 (spray-equipment.tecnopolgroup.com) or similar
  • free from harmful VOC compounds, therefore, it does not hurt the ozone layer (VOC's zero). TECNOCOAT P-2049 LV system is 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.
  • its application is recommended directly on the structural concrete slabs. The product is certified to be applied at zero slopes, for ponding water. In this way, the execution of mortar slopes or other protective materials is not necessary to do.
  • thanks to its versatility and its tack-free time of around 5 seconds (reduces facility downtime) TECNOCOAT P-2049 LV adapts to any surface, making it the ideal product for application on uneven surfaces and in areas of any shape, whether curved or squared.
  • TECNOCOAT P-2049  LVsystem's properties enable it to bond to any surface, such as concrete, ceramic tiles, polyurethane foam, wood, metals, bituminous sheets, acrylic paints ( for other surfaces, please contact us)
  • 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 P-2049  LV 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.
  • TECNOCOAT P-2049  LV pure polyurea coating 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 in the TDS
  • the TECNOCOAT P-2049 LV system requires solar radiation protection (UV rays) to do not lose its physical and mechanical properties, given that it is an aromatic membrane., so is necessary to use a polyurethane colored aliphatic resin, TECNOTOP 2C, for use in the absence of other physical protection elements. You can apply too TECNOTOP S-3000, our polyaspartic resin for coating and UV protection.
  • The range of ambiance temperatures of application is between 3ºC to 35ºC. Max. relative humidity 85%
  • the fast reaction of TECNOCOAT P-2049  LVupon application provides great stability in a few seconds and it may be walked on and guarantees waterproofing in less than 3 hours. This polyurea coating reaches its optimum conditions after approximately 24 hours.

APPLICATION METHOD

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)
  • 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
  • clean up the surface or substrate, removing any dust, dirt, grease, or efflorescence.

NOTE: in case of doubt of all above, apply before in a restricted area and to check, also carry out some adhesion test

The TECNOCOAT P-2049 LV 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 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 our epoxy resin PRIMER EP-1010 
  • 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 6 from ICRI Guide 03732, depending on the final use). Recommended CSP 3 or CSP 4.
  • 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 two-component polyurethane PRIMER PU-1050/PRIMER PUc-1050, the epoxies PRIMER EP-1010, PRIMER EP-1020, or PRIMER EPw-1070 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 with a short nap roll or electrical "airless" equipment(consult the TDS of these products before 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 quick 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, PRIMER Ep-1010, 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 with short hair roller type equipment "airless" (consult the TDS of these products before 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; check the situation of the sheets and value the actions to do
  • there shall be cleaned with water to complete evaporation.
  • remove and replace some sections if need be
  • next to 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 with short hair roller type equipment "airless" (consult the TDS of these products before use)

Notes:

  • 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
