GENERAL FEATURES

  • Excellent bond and great coverage.
  • High surface hardness, and slightly flexible
  • Excellent bonding/adherence to concrete
  • Chemical resistance medium level
  • It is recommended that the same batch number is used in each area of application to ensure an even color is obtained.
  • To reduce the risk of condensation, both the substrate and the ambient temperature should be a least 3 ºC above dew point at the time of application.
  • TECNOFLOOR PU-3010 d should be applied in dry conditions avoiding the presence of humidity or water 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.
  • Don’t add water.
  • Total curing takes 7 days; until then, avoid direct contact with water or other reactants.
  • Do not apply at temperatures below 10 ºC or above 30 ºC and with relative humidity above 80%.

PACKAGING

Metal tins 20 kg

SHELF LIFE

24 months at temperatures between 5° C and 35° C, provided it is stored in a dry place. Once the tin has been opened, the product must be used immediately.

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)
  • clean up the surface or substrate, removing any dust, dirt, grease or efflorescence.
  • 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
  • in case of doubt of all above, apply before in a restricted area and to check

TECNOFLOOR PU-3010 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.

Cement or concrete surfaces

  • 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.
  • fill joints with MASTIC PU, polyurethane mastic
  • 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.
  • clean up the surface or substrate, removing any dust, dirt, grease or efflorescence.
  • apply PRIMER PU-1050/PRIMER PUc-1050/PRIMER PU-1000/PRIMER EPw-1070, with a yield approximately 250 g/m² (two layers) always depending on the state of the substrate or the surface's porosity.
  • apply by roll, thin layers of colored TECNOFLOOR PU-3010

COMPLEMENTARY PRODUCTS

TECNOFLOOR PU-3010, may be complemented with the following products as a means of protection or to improve its physical-mechanical properties depending on its exposure, the desired finish or the type of substrate.

  • PRIMER EP-1020: mixed with silica sand in a ratio of ±1:4, or calcium carbonate in ratio ±1:2, this is used to fill in depressions in concrete surfaces, rapidly providing a firm and fast drying even base.
  • PRIMER PU-1050/PRIMER EPw-1070/PRIMER PUc-1050/PRIMER PU-1000: these several resins are applied on the substrate beforehand to improve bonding and level the surface, as well as regulating the humidity in the substrate (see permitted levels in their technical specifications).Consumption may vary depending on the type of support, nature or surface texture. Consult the technical specifications of each product or our technical department.
  • MASTIC PU: polyurethane mastic for filling joints (use together with TECNOBAND 100 when necessary).

HANDLING AND TRANSPORT

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.

Anyway, consult the safety data sheet of the product(MSDS) or contact our technical department.
