TECNOTOP 2CP

Two-component, aliphatic polyurethane solvent based resin (suitable for full immersion and chlorinated behavior)

TECNOTOP 2CP is a two-component aliphatic, colored, glossy, polyurethane solvent-based resin for coating, flooring, decoration, and especially for the protection of the waterproofing liquid systems (TECNOCOAT y DESMOPOL) against the UV rays. It has continuous finishing and forms a hard, strong, continuous film, with excellent adhesion and mechanical properties.  The excellent resistance to abrasion, wear, and stress make it resistant to weathering and extreme ambiance temperature. Suitable for surfaces and areas in contact with chlorinated and salines waters, even immersion use that is particularly suitable for the lining of pools, lakes, or aquatic areas.

GENERAL FEATURES

  • It is a glossy, aliphatic, colored or translucent, solvent-based polyurethane resin fo  in chlorinated/salt areas.
  • The translucent version can be colored mixing PIGMENTS PU during the installation (20% on weight)
  • The colored version, it's served on any RAL color, except metallic ones (check sale conditions on the price list)
  • It forms a continuous coating, easy to clean and maintain, and resistant to algae and mold growth.
  • Suitable for ponding water, and works under ponding water on a variety of surfaces: concrete, cement, ceramics, TECNOCOAT, or DESMOPOL membranes (for UV rays protection)
  • TECNOTOP 2C 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 their maximum humidity ranges are specified.
  • 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.
  • It can be thinned using DESMOSOLVENT, up to 5% for applications with airless spray equipment.
  • Adding the product pool cleaning must be done by automated equipment controlled mixing, never added directly to the surface thereof applied TECNOTOP 2CP.

YIELD

The yield of TECOTOP 2CP varies depending on the layers applied, the type of substrate, or the final use. After mixing both components using an electrical stirrer (low-medium speed), apply thin coats by a short nap acrylic wool roller brush or airless spray equipment; consumption is approximately 150~200 g/m²/layer to get a maximum of 300 g/m² depending on the final use or kind of application. Consult consumptions to our technical department or see the waterproofing liquids systems' Technical Guidelines.

PACKAGING

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 the case of Tecnotop 2CP neutral version, add the proper quantity of PIGMENTS PU (20%) inside the component A and mix until getting a homogenized product, using an electric mixer medium speed; after that, add component B
  • in the case of Tecnotop  2CP 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 2CP 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 a short nap acrylic wool roller,, thin layers of colored TECNOTOP 2CP (total consumption 250 g/m², depending on the scope)
  • in the case of swimming pools and areas of contact total immersion of water, wait 5-6 days to fill.

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 of 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 a short nap acrylic wool roller, thin layers of colored TECNOTOP 2CP(total consumption 250 g/m² depending on the scope)
  • in the case of swimming pools and areas of contact total immersion of water, wait 5-6 days to fill.

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 a short nap acrylic wool roller, thin coats of colored TECNOTOP 2CP(total consumption 250 g/m² depending on the scope)
  • in the case of swimming pools and areas of contact total immersion of water, wait 5-6 days to fill.

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 2CP 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 a short nap acrylic wool roller, thin coats of colored TECNOTOP 2CP (total consumption 250 g/m² depending on the scope)
  • in the case of swimming pools and areas of contact total immersion of water, wait 5-6 days to fill.

APPLICATION FINISHINGS

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

multilayer system, adding SILICA SAND

  • apply an initial coat of TECNOTOP 2CP, by a short nap acrylic wool roller, 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 2CP, by a short nap acrylic wool roller, 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 2CP component A package.
  • add the Tecnotop 2PC component B in the initial mixture, beat with electrical mixing equipment at medium speed
  • paving a layer of mixed TECNOTOP 2CP, by a short nap acrylic wool roller, and made in thin layers (consumption approximately 150-175 g/m²).
  • if necessary, apply a second final coat of TECNOTOP 2CP 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).

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.
  • 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 material and safety data sheet of the product(MSDS) or contact our technical department.

COMPLEMENTARY PRODUCTS

TECNOTOP 2CP 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-1010: 100% solids, two-component,  fillerized epoxy resin, to fill in depressions in concrete surfaces, one coat application so,  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 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 2CP, 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).
