GENERAL SPECIFICATIONS

  • Two-component, 100% solids content, aromatic polyurea that once applied, forms a hard-wearing, continuous, seamless, waterproofing, and solid membrane that offers a certified waterproofing, watertight behavior.
  • It holds an ETA 20/0263, 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 1.4 mm thickness, ponding water admitted
  • Green roof application certified, root resistance,according to the EN 13948 (ETA 20/0263)
  • It has CE marking on the basis of a statement made DoP Declaration of Performance (DoP) conforms to the regulations UE 305/2011
  • The application and training are done by our spray equipment TC2049 (spray-equipment.tecnopolgroup.com) or similar
  • Thanks to its versatility and its tack-free time of around 3-5 seconds, allows the adherence to any surface, making it the ideal product for application on uneven surfaces and in areas of any shape, whether curved or squared.
  • Due to its resistance, it can be walked on and it will accept a rough finish to make it non-slip. (using Silica Sand or Tecnoplastic range aggregates)
  • A ceramic floor can be placed on top. In this case, we recommend applying a thin coat of Primer PU-1000 or Primer PU-1050, consumption of around 50 to 60 g/sqm, and spreading Silica Sand on top, consumption of around 700-1000 g /sqm, to improve mechanical anchorage.
  • Joints and any type of union are saved since the finish is uniform and in one piece, providing a surface with optimal maintenance and cleaning.
  • His properties allow it to adhere to any surface such as concrete, ceramic tiles, metals, spray polyurethane foam (Tecnofoam), plywood(OSB), 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.
  • 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.
  • 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.
  • It is an aromatic membrane and, even though it is stable against solar radiation it requires solar radiation protection (UV rays) to do not lose its physical and mechanical properties. Therefore, our approved system (under ETA 20/0263), incorporates a protective polyurethane colored aliphatic resin, Tecnotop 2C, for use in the absence of other physical protection elements. You can apply  Tecnotop S-3000, Tecnotop 2CP or Tecnotop 1C also.

REPAIR AND OVERLAPS PROCESSES

REPAIR
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/spray the membrane evenly and in several layers until the dry film thickness required by the project is achieved.
  • application of the aliphatic polyurethane resin for protection against UV rays Tecnotop 2C/2CP/1C

OVERLAPS
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/spray the membrane evenly and in several layers until the dry film thickness required by the project is achieved.
  • application of the aliphatic polyurethane resin for protection against UV rays Tecnotop 2C/2CP/1C

APPLICATION REQUIREMENTS (spray equipment)

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

  • Isocyanate heater temperature: 70-75 ºC (158ºF to 167ºF)
  • Resine heater temperature:70-75ºC   (158ºF to 167ºF)
  • Hose temperature:±70 ºC (158ºF )
  • Working pressure: 2.500 - 3.000 psi (170 to 205 bar)
  • Recommended mixing chamber: GU-07008-1 or GU-07008-2 (use mechanical purge chamber)

These temperatures and pressure parameters must be valued, ratified or slightly varied by the applicator, depending on the conditions of each climatic zone, weather situation or according to the specifications of the projection equipment. It is the responsibility of the owner / applicator of the equipment to keep it in perfect condition in order to maintain the correct mixing ratio of the two components that Tecnopol delivers separately, by periodically updating its maintenance controls. During the execution of the application, it may be necessary to correct these parameters according to changing external conditions, as well as to verify the correct operation of the machine (pressure and temperature).

HEALTH AND SAFETY

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 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.
  • Re-occupancy of the work site without respiratory equipment is minimum 24 hours providing the correct ventilation for the area sprayed.
  • Contractors and applicators must comply with all applicable and appropriate guidelines for storage and safety guidelines.

Anyway, consult the material and safety data sheet of the products of the system.
