• It's a very elongable product that, once applied, offers great stability, durability, waterproof and seal, and a thermal isolation behavior
• the application and training is done by our spray equipment TC2049 (spray-equipment.tecnopolgroup.com) or similar
• Its application is recommended directly on the structural concrete slabs. The product is certified to be applied at zero slopes. In this way, the execution of slopes of mortar or other protective materials are not necessary to do
• Thanks to its versatility and its drying time of between 3 and 5seconds TECNOCOAT P-2049 EX adapts to any surface, making it the ideal product for application uneven surfaces and in areas of any shape, whether curved or squared.
• Applying TECNOCOAT P-2049 EX 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.
• TECNOCOAT P-2049 EX 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 where the maximum humidity ranges are specified or our  technical handbook of application of TECNOCOAT
• The fast reaction of TECNOCOATP-2049 EX upon application provides great stability in a few seconds and it may be walked on and guarantees to waterproof in less than 3 hours. This polyurea reaches its minimum conditions after approximately 24 hours.
• The TECNOCOAT P-2049 EX system's properties enable to bond to any surface, such as cement, concrete, polyurethane, wood, metal, etc.

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 the 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.
• 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:

Sheets substrate:

• The existing sheet surfaces (asphalt, bitumen…) must not show surface areas raised or not in good condition. He withdrew in poor areas.
• There shall be cleaned with water, ensuring complete evaporation.
• Next, apply the required primer; in these cases of non-porous surfaces use the water-based epoxy PRIMER EPw-1070 or polyurethane solvent-based PRIMER PU-1000

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

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 a thin layer (±80 g/m²) of polyurethane resin PRIMER PU-1000
• light spread SILICA SAND over the wet primer applied before
• wait for the total drying

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 (±80 g/m²) of polyurethane resin  PRIMER PU-1000.
• light spread SILICA SAND over the wet primer applied before
• wait for the total drying

HANDLING

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.

Anyway, consult the safety and material data sheet of the product, are publicly available.

COMPLEMENTARY PRODUCTS

The TECNOCOAT P-2049 EX 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: These primers 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.
• PRIMER EP-1040: 100% solid content, epoxy resin, for metal surfaces
