TECNOCOAT P-2049 EX
TECNOCOAT P-2049 EX is a two-component, sprayable, aromatic coating suitable for waterproofing, protection, sealing, and thermal insulation. It's made up of two high reactive liquid components, isocyanates and amines, mixed using our specific spray equipment (TC2049 http://spray-equipment.tecnopolgroup.com/) or similar, to form a solid, continuous, watertight and waterproof, seamless, high-density pure polyurea membrane. This polyurea once applied, expands between 5 and 7 times its volume.


Uses
For waterproofing and protection of concrete decks or metallic supports on:
- Asbestos /metal roofs.
- Sloped roofs, terraces, balconies, and overhangs
- concrete decks, retaining walls, and foundations.
NOTE: call our technical department about the application to other supports or situations

GENERAL FEATURES
- TECNOCOAT P-2049 EX forms a wearing thick product that, once applied, offers great stability, durability. It helps to the planimetry of the substrate and to the thermal insulation
- the application and training is done by our spray equipment TC2049 (spray-equipment.tecnopolgroup.com) or similar
- It's a product that, once applied, offers great stability, durability, waterproof and seal, and a thermal isolation behavior
- thanks to its versatility and its drying time of between 3 and 5 seconds TECNOCOAT P-2049 EX adapts to any surface, making it the ideal product for application on uneven surfaces and in areas of any shape, whether curved or squared.
- it saves in seals and any other kind of joins, as the finish is uniform and makes up a single layer, providing a surface with optimum maintenance and cleaning properties.
- it should be applied in dry conditions avoiding the presence of humidity or 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 in the TDS.
- the system's properties enable it to bond to any surface, such as cement, concrete, polyurethane, wood, metal, etc. Furthermore, due to its resistance, it can be walked on and it will accept a rough finish to make it non-slip (according to ENV 12633:2003)
- his properties allow it to adhere to any surface such as concrete, ceramic tiles, metals, plywood, asphalt/bituminous sheets. In any case or material, the surface must be consistent, firm, clean, and dry when the products are applied. Recommended applying directly on the concrete deck. Ponding water admitted.
- free from harmful VOC compounds, therefore, it does not hurt the ozone layer (VOC's zero). It's 100% recyclable by mechanical means friendly to the environment; no gas collection for recycling and/or destruction is required; it doesn´t emit substance to the environment once installed.
- the system requires solar radiation protection (UV rays) to do not lose its physical and mechanical properties, given that it is an aromatic membrane. The system incorporates a protective polyurethane-colored aliphatic resin, TECNOTOP 2C, for use in the absence of other physical protection elements. You can apply too TECNOTOP S-3000, TECNOTOP 2CP or TECNOTOP 1C.

APPLICATION METHOD
In general, the following aspects should be dealt with prior to spraying:
- Repair the surface (fill in depressions, eliminate unevenness, eliminate any old waterproofing, etc.).
- Clean the surface or substrate, removing any dust, dirt, grease, or efflorescence.
The TECNOCOAT P-2049 EX pure polyurea system 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.
Concrete substrate
- any depressions or voids should be repaired using a mix (ratio ± 1:4) of our epoxy resin PRIMER EP-1020 mixed with silica sand
- 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 and eliminate all contaminants from the elements, such as dust or particles from the previous processes.
- application of the TECNOCOAT P-2049 EX polyurea membrane. Apply a single layer and achieve a thickness of approx. 8-9mm. If more total thickness is necessary depending on the definition of the project, apply them once the first applied layer has cooled.
- application of the aliphatic resin TECNOTOP S-3000/2C/2CP, in consumption and desired thicknesses in the case of no protection against UV rays. This application can be done by short hair roller type equipment "airless" (see the conditions of application in the product datasheet TDS)
Metal substrate:
- metal surfaces should be prepared using sand-blasting, in order to improve the surface's mechanical fixation properties.
- check the seals and overlaps and where necessary seal with MASTIC PU mastic or TECNOBAND 100, in combination.
- for rapid and efficient cleaning of the surface using a ketone-based solvent
- applies prior priming using a 100% solids epoxy resin PRIMER EP-1040 or water-based epoxy resin PRIMER EPw-1070, to improve surface leveling and bonding. Consult the technical specifications of this product.
- application of the TECNOCOAT P-2049 EX polyurea membrane. Apply a single layer and achieve a thickness of approx. 8-9mm. If more total thickness is necessary depending on the definition of the project, apply them once the first applied layer has cooled.

Ceramic substrate:
- ceramic surfaces should not have empty joints or loose elements or parts. These should be filled with MASTIC PU mastic, complemented with TECNOBAND 100 on the joints if necessary.
- for rapid and efficient cleaning of the surface use pressurized water and check that it evaporates completely. Also, verify that all dust and other physical contaminants have been eliminated.

REPAIR AND OVERLAPS PROCESSES
REPAIR
In cases where the membrane repair by accidental causes, or assembly procedures not covered installations, shall be as follows:
- cut, removal of the affected area and/or damaged surface
- sanding this area extending about 20~30 cm. around the perimeter, for overlapping security
- cleaning (vacuuming) of waste generated (powder, dust...); if it's possible don't use water, and if used, support humidity value; ketones applicability based solvents for reducing this type of surface cleaning

- apply TECNOTOP S-3000/2C/2CP, in consumption and desired thicknesses in the case of no protection against UV rays.
OVERLAPS
In cases has been exceeded recoat time (24~48 hours), so the waiting time between jobs is prolonged, proceed as follows:
- sanding strip longitudinal overlap of about 20~30 cm. wide
- cleaning (vacuuming) of waste generated (powder, dust...)or existing dust; if it's possible, do not use water, and if it's used, check the support humidity value; ketones applicability based solvents for conducting this type of surface cleaning
- apply a thin layer (100-150 g/sqm) of polyurethane resin PRIMER PU-1050, PRIMER EPw-1070

APPLICATION REQUIREMENTS (spray equipment)
For the formation, it is necessary to mix the two initial liquid components, isocyanates and amines by our spray equipment TC2049 (spray-equipment.tecnopolgroup.com) or similar (proper maintenance and cleaning it is recommended). The general parameters for this material will be the following:
- Isocyanate heater temperature:± 65-68 ºC
- Amine heater temperature: ±65-68ºC
- Hose temperature ±65 ºC
- Working pressure: 2.500 to 3.000 psi
- Recommended mixing chamber: GU-07008-1 (use mechanical purge chamber)
Anyway, these parameters for adjusting the projection equipment are approximate and may change depending on the weather conditions of the environment at the moment to apply, therefore, it is the responsibility of the applicator values in each case the option to choose.
