Uses

For flooring and protection of:

  • Pavements of heavy traffic as for garages, car parks
  • Pavements of high decontamination and cleaning requirements  as in chemical and food industries
  • Pavements of high decontamination and cleaning requirements  as in chemical and food industries
  • Pavements where required an anti-slipping finished surface (multilayer application)
  • Water waste tanks
  • Sealing concrete

NOTE: call our technical department about the application to other supports or situations

consumption depending on substrate and method of application
tensile strength at 23ºC ±15 MPa
elongation at break at 23ºC <75%
total dry time at 23ºC ± 7 days
walkable at 23ºC ± 24 hours
application method roller, notched trowel

GENERAL FEATURES

  • Excellent bond and great coverage.
  • Breathable (permeable to steam).
  • 100% solids.
  • Chemical resistance
  • 1mm thickness per coat
  • No solvent, odorless
  • High surface hardness, and slightly flexible
  • Excellent bonding/adherence to concrete
  • 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-3060 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:

  • LARGE KIT:19,5 kg + 5,5 kg
  • SMALL KIT: 3,9 kg+1,1 kg

EXPIRY

12 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

Substrate:

  • The concrete slab should have a minimum tensile strength of >1.5 N/mm² (MPa) and be free from grease, oil, concrete laitance, curing liquids or any other treatments, such as silicones or deteriorated paint.
  • The substrate should be open pore and, therefore, it is essential to commence by milling or sandblasting, followed by dust aspiration. Sanding is not recommended as a rough, open pore surface is needed to guarantee fixation of the primer.
  • Concrete must be over 28 days old (finished setting process), or a moisture content <4%.
  • The substrate can be damp, but it should be noted that TECNOFLOOR PU-3060 may not be applied on concrete that exudes water or in areas where the phreatic water level could affect bonding of the system's components, which could cause the coating to bubble.

Primer:

  • It’s essential to first of all to prime the surface using our primers (according the kind and conditions of the support): PRIMER EP-1020/PRIMER EPw-1070/PRIMER PU-1050/PRIMER PUc-1050, in order to improve surface bonding and saturate the concrete's pores, clogging them to ensure a perfect bond with the surface and absence of bubbles in the subsequent finish.
  • After applying the primer it is necessary to wait between 6 hours and 8 hours maximum for the application of TECNOFLOOR PU-3060, under 23 ° C and 80% relative humidity.

Mixing:

  • TECNOFLOOR PU-3060 comes pre-weighed in the appropriate amounts for subsequent mixing. Partial mixes of the pre-weighed components are not recommended.
  • Shake the tin containing Component A and then pour in the contents of Component B. Mix using a rod stirrer at low speed until the mixture is thoroughly combined. Make sure you stir well around the edges and at the bottom of the tin.

APPLICATION TYPOLOGIES

Paint:

  • Apply TECNOFLOOR PU-3060 using a roller (min. two layers). Consumption is approximately 500 g/m² and layer applied, depending on the roughness of the substrate

Multilayer:

  • Apply TECNOFLOOR PU-3060 using a short hair roller
  • Sprinkle the surface with silica sand until it is saturated.
  • Once hardened sweep away the excess sand. 
  • Lightly sand down the surface, aspirating the residue.
  • A rubber fork and then a short nap roller may be used to give the coating its finish.

Self-leveling:

  • For this type of application, the material is poured on the support, then distributing it with a notched trowel with which you can control thickness and consumption. Once past 20 minutes is necessary to pass a spiked roller with which the air outlet will facilitate within the material
  • The minimum thickness to get self-leveling is 1 mm.

COMPLEMENTARY PRODUCTS

The TECNOFLOOR PU-3060 polyurethane system 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)

Performance may vary depending on the type of support, nature or surface texture. Check the technical specifications of each product.

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.
  • 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.
