GENERAL FEATURES

  • It is a completely aliphatic solvent-based, glossy and colored or translucent polyurethane resin, forming a continuous, continuous coating without joints or overlaps. great adherence to the substrates and easy to clean and maintain.
  • It is delivered in any non-metallic RAL color (check the delivery conditions of minimum quantities in the price list)
  • In the case of the translucent version, the coloring is carried out by adding the two components, previously mixed, of Pigments PU (20% by weight)
  • It has an SRI Index according to ASTM E1980-11 (Tecnotop 2C White color)
  • Suitable for ponding water, on a variety of surfaces: concrete, mortar, steel/metal, cement, plywood, ceramics, Tecnocoat and Desmopol  membranes (for UV rays protection)
  • It must be applied in sound and resistant substrates, with no presence of humidity/water on the surface whether at the time of application or subsequently (pressure from phreatic water level, damp-water). In the event there is humidity in the substrate at the moment of application, use some of our primers. 
  • The final product is obtained by mixing 100% of the two components. If only part of the product is used, make sure that this ratio is always maintained to ensure that the final result retains the product's best qualities.
  • Use the same batch of product in each area of application to avoid the minimum and possible color change
  • Do not apply for swimming pool coatings (for this use, use Tecnotop 2CP)

  • mix using electric mixing equipment at medium speed, until a homogeneous product is obtained
  • in case of doubt, apply in a limited area to check

APPLICATION METHOD

The following factors prior to application should be checked:

  • previous preparation of the substrate according to its type
  • existing holes or areas with a lack of material must be repaired using some or our epoxy resins: Primer EP-1020/Primer EP-1010
  • joint fillings with Mastic PU
  • in existing dilatations joints: remove old material, clean, and fill with Mastic PU. Use also Tecnoband 100 to cover, if necessary.
  • general cleaning of the substrate, removing existing dust, dirt, grease, or efflorescence

TECNOCOAT/DESMOPOL, waterproofing membranes substrates

  • clean up the surface or substrate, removing any dust, dirt, grease, or efflorescence
  • apply PRIMER PU-1000/PRIMER EPw-1070, with a yield of approximately 50~70  g/sqm, if the time of application of membrane(TECNOCOAT or DESMOPOL) is over 24~48 h, and depending on the state of the substrate or the surface's porosity too.
  • apply thin coats by a short nap acrylic wool roller or "airless" equipment

Cement or concrete substrates

  • the concrete must be completely cured (the curing process is 28 days), or in any case, it is necessary to check the maximum degree of moisture permittivity of the substrate depending on the primer to be used
  • processes to prepare the substrate (sanding, polishing, shot-blasting or milling) to remove surface laitance, and release agents, as well as to open the surface pore and achieve a suitable anchoring profile.
  • Existing holes or areas with a lack of material must be repaired using some of our epoxy resins: Primer EP-1020/Primer EP-1010.
  • joint filling with Mastic PU
  • in existing work joints: empty of old material, clean and fill with Mastic PU. Complement the joints with Tecnoband 100 if necessary.
  • cleaning of the substrate, removing existing dust, dirt, grease or efflorescence by mechanical suction
  • primer application, recommended Primer PU-1050/Primer PUc-1050 , total consumption approx. 250 g/sqm (applied in several thin coats) or Primer WET depending on the existing humidity in the substrate and with a total consumption of 450 g/sqm (apply in one single coat) . Primer consumption may vary depending on the physical characteristics of the substrate or its absorption coefficient.
  • apply thin coats by a short nap acrylic wool roller or "airless" equipment

Ceramic substrates

  • light-sanding of the surface. This action will open the pore, clean of adhered efflorescence or dirt, and regularization of the surface by extracting the raised or unattached areas, without adding water.
  • ceramic substrate there should be no empty joints, elements, or loose pieces. They must be filled with Mastic PU, or with some of our epoxy resins: Primer EP-1020/Primer EP-1010; also use cementitious materials.
  • joint filling with Mastic PU
  • in existing work joints: empty of old material, clean and fill with Mastic PU. Complement the joints with Tecnoband 100 if necessary.
  • cleaning of the substrate, removing existing dust, dirt, grease or efflorescence by mechanical suction
  • primer application, recommended Primer EP-1040, total consumption approx. 100-150 g/sqm (applied in several thin coats), or Primer EPw-1070 (applied in several thin coats), total consumption approx. 150-200 g/sqm. Primer consumption may vary depending on the physical characteristics of the substrate or its absorption coefficient.
  • apply thin coats by a short nap acrylic wool roller or "airless" equipment

Painted surfaces

  • if the existing paint is in good condition, clean its surface with a mixture of water and an industrial detergent, wait to dry
  • If the situation of the existing paint is not optimal sanding of the surface will be carried out, to avoid the contribution of water to the substrate. This action will open the pore, clean of adhered efflorescence or dirt, and regularization of the surface by extracting the raised or unattached areas, without adding water.
  • cleaning of the substrate, removing existing dust, dirt, grease or efflorescence by mechanical suction
  • primer application, recommended Primer EPw-1070, total consumption approx. 150-200 g/sqm (applied in several thin coats). Primer consumption always subject to the physical characteristics of the substrate and its absorption coefficient.
  • apply thin coats by a short nap acrylic wool roller or "airless" equipment

APPLICATION FINISHINGS

If desired, an anti-slip finish can be created with the following methods:

Multilayer method with SILICA SAND

  • application of a first one by means of a short-haired acrylic wool roller or "airless" type equipment and carried out in thin coats(approximate consumption of 70-100 g/sqm/coat)
  • Spreading on the wet substrate Silica Sand in the consumption desired by the customer. Hence an anti-slip surface is achieved to enable the system to have a degree of slip resistance.
  • wait for it to dry and remove the aggregate not adhered to the surface; refill with aggregates areas not defined correctly, if necessary
  • vacuum up non-adhering aggregates
  • application of a second coat by short nap acrylic wool roller or "airless" equipment and carried out in thin coats (approximate consumption of 70-100 g/sqm/coat)

Addition of TECNOPLASTIC F/C

  • mix Tecnoplastic F/C, mixing ratio:maximum 8-9% (recommended ±7%) in the resin pail.
  • stirr/mix with electric mixer at medium speed until homogenize
  • spread in one coat, using a short nap acrylic wool roller and made in thin coat (approximate consumption of 70-100 g/sqm/coat)
  • if necessary, apply a second final coat without mixing with Tecnoplastic F/C.

NOTE: For other types of substrates, weather conditions or final use, consult our technical department.
