APPLICATION METHOD

In general, you should take the following factors:

  • repair the surface (fill in depressions, eliminate unevenness, eliminate any old waterproofing, etc.)
  • detail works(perimeter, sinks/drainages, 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 Tecnotop 2C neutral version, add the proper quantity of PIGMENTS (20%) inside the component A and mix until getting a homogenized product, using an electric mixer medium speed; after that, add component B
  • in case of Tecnotop  2C already pigmented, pour component B on component A and stir to getting a homogenized product
  • in case of doubt of all above, apply before in a restricted area and to check

TECNOTOP 2C 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.

TECNOCOAT/DESMOPOL, waterproofing membranes

  • 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/m², 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 by roll, thin layers of colored TECNOTOP 2C (total consumption 200 - 300 g/m², depending on the scope)

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 laitance 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, with a yield approximately 250 g/m² (two or more thin coats) always depending on the state; or apply PRIMER WET, total consumption around 450 g/m². Consumptions depending on the state o of the substrate or the surface's porosity or humidity.
  • apply by roll, thin layers of colored TECNOTOP 2C(total consumption 300 g/m² depending on the scope)

Ceramic surfaces

  • continuous sanding of the surface, to avoid the addition of water to the substrate. This action will lead to the opening of the pore of the ceramic flooring, cleaning of adhering efflorescence or dirt, and regularisation of the surface, without the addition of water.
  • on ceramic surfaces, there must be no empty joints, elements or loose pieces. They must be filled with MASTIC PU or with our mortar made with our epoxy resin PRIMER EP-1020 and silica aggregate (ratio ±1:4), or cementitious materials used to make joints.
  • in existing expansion joints: empty old material, clean and fill with MASTIC PU. Complement the joints with TECNOBAND 100 if necessary (in joints greater than 20 mm wide).
  • after that,  the entire surface must be cleaned and removed from contaminants such as dust or particles from these previous processes by mechanical vacuuming.
  • apply PRIMER EP-1040 epoxy resin with a total consumption of 100-150 g/m² or  PRIMER EPw-1070 epoxy water-based resin, with a total consumption of around 150-200 g/m² (two or more thin coats)  always depending on the state of the substrate or the surface's porosity. 
  • apply by roll, thin coats of colored TECNOTOP 2C(total consumption 300 g/m² depending on the scope)

Painted surfaces

  • if the existing paint is in good condition, clean the surface with a mixture of water and industrial detergent. Leave to dry.
  • remove the existing paint if it does not offer good bonding conditions and eliminate any substrate in poor condition as this could hamper TECNOTOP 2C bonding.
  • clean up and leave to dry
  • apply PRIMER EP-1040 epoxy resin with a total consumption of 100-150 g/m² or  PRIMER EPw-1070 epoxy water-based resin, with a total consumption of around 150-200 g/m² (two or more thin coats)  always depending on the state of the substrate or the surface's porosity. 
  • apply by roll, thin coats of colored TECNOTOP 2C (total consumption 300 g/m² depending on the scope)

APPLICATION TYPES

If so required, TECNOTOP 2C can be applied with a non-slip finish as follows:

multilayer system, adding SILICA SAND

  • apply an initial coat of TECNOTOP 2C, by a roll or mechanical equipment in the thin coat (consumption of 100-150 g/m²)
  • spread with SILICA SAND, over the still wet resin. Consumption up to the final client or user
  • wait for the drying
  • remove silica sand not adhered using a broom; repair the areas without bonded sand
  • apply an initial coat of TECNOTOP 2C, by a roll or mechanical equipment in the thin coat (consumption of 100 g/m²)

TECNOPLASTIC F/C system

  • mix our TECNOPLASTIC F/C with the desired mixing ratio, maximum 8-9%, recommended ±7% in the Tecnotop 2C component A package.
  • add the Tecnotop 2C component B in the initial mixture, beat with electrical mixing equipment at medium speed
  • paving a layer of mixed TECNOTOP 2C, by roller and made in thin layers (consumption approximately 150-175 g/m²).
  • if necessary, apply a second final coat of TECNOTOP 2C without mixing with TECNOPLASTIC F/C. The system is also certified to comply with the ENV 12633:2003, according to its dosage (consult our technical department).

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

COMPLEMENTARY PRODUCTS

TECNOTOP 2C 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 EP-1040 | PRIMER EPw-1070 |PRIMER PUc-1050 |PRIMER PU-1000 |PRIMER WET | PRIMER EP-1020: 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
  • TECNOPLASTIC F/C: this plastic powder, once mixed with TECNOTOP 2C forms a rough surface, conforming even to norm ENV 12633:2003 (floors slipperiness), to achieve Class 3 (>45 slip resistance), depending on dosage (consult our technical department).
  • TECNOBAND 100: the cold bond deformable band made up of an upper layer of non-woven textile and a lower layer of viscoelastic self-adhesive coating, which together allow it to adapt to the shape of the substrate. This band is ideal when dealing with structural joints and overlapping metal materials.
  • 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.
