TECNOCOAT products are a range of high quality waterproof membranes produced by subjecting their liquid component to high temperatures and pressure. Their excellent mechanical properties have made them one of the most widely used membranes for construction work involving demanding technical specifications.

TECNOCOAT is a range of products designed for waterproofing and protection in general.

Within the TECNOCOAT line we would highlight TECNOCOAT P-2049, a projectable bi-component pure polyurea which forms a 100% solid and waterproof membrane, with no joins or overlaps, completely adherent to the surface, environmentally sound and with the additional advantage of drying in just 5 seconds.

Thanks to its high level of adherence to the majority of surfaces, TECNOCOAT products provide a secure and permanent union with the surface, ensuring a rust and corrosion free finish which can be made anti-slip and is available in any colour.

TECNOCOAT coverings are extremely durable, resistant to chemical products and provide excellent and lasting results in all weather conditions.

TECNOCOAT P-2049 is applicable for a long list of surfaces, the most common applications and therefore more recommended are, polyurethane foam, fiberglass, wood, ceramic, metal, concrete etc.

Elastómero de poliurea pura aromática bicomponente que una vez aplicado proporciona un recubrimiento impermeabilizante sin juntas, continuo y completamente adherido al soporte; de alta resistencia al desgaste y a la abrasión, así como al contacto con productos químicos. Con un secado al tacto de tan sólo 4 segundos, puede ser transitable por tráfico rodado en un período inferior a las 3 horas.

La membrana TECNOCOAT P-2049 posee certificación ETE 11/0357 con una vida útil de 25 años para un grosor mínimo de 1,4 mm.

but... what its pure polyurea?

In terms of molecular structure, a PURE POLYUREA membrane is obtained by mixing two reactive components: an isocyanate group and amines. The reaction of the amines with the isocyanate group results in the formation of a urea linkage. Polyurea membranes can be formulated as hybrids by combining the two components above with a mixture of polyols. If only polyol linkages are present the result of the reaction is polyurethane.

TECNOCOAT P-2049 is applicable for a long list of surfaces, the most common applications and therefore more recommended are, polyurethane foam, fiberglass, wood, ceramic, metal, concrete etc..

• As a coating to separate internal and external agents very useful for tubes carrying water, chemicals, seweage, gas, etc.
• For waterproofing in the construction of swimming pools, reservoirs or deposits. Indicated especially for the effective waterproofing of gardens, landscape coverings (VYDRO) and other outdoor constructions.
• For transited surfaces that need to be waterproofed like flat or sloped roofs or patios. Also very indicated as anticorrosive treatment the case of metal, such as the protection of a low layer of polyurethane foam that is outdoors or for encapsulating fiber cement siding.

• In the protection of interior coatings of vehicles, vans, trucks against the corrosion of climate agents. As well as the long-term maintenance for continued use.

1. Support

The substrate should be consistent and have a tensile strength of 20 ~ 25N/mm2 (HA-20 ~ HA-25), as our membranes have adhesion strengths of up to 1.85 N/mm2. If you are not certain of the strength you should inspect the substrate and, where possible, carry out tests to determine the tensile strength.

2. Support Preparation

CONCRETE SUBSTRATES

If there is a weak layer of cement on the substrate or it has an uneven surface you should prepare it mechanically (milling, sanding, shot-blasting).

If there are any cracks or small holes they should be filled in and compacted with the appropriate filling, made using our PRIMER EP-1020 product which is very hard and fast drying.

Specific areas, such as structural joints and perimeter flashings with walls, should be prepared using DESMOSEAL MASILLA-PU putty and/or TECNOBAND 100 (ask our technical department). When all the preliminary work to prepare the substrate has been completed you should clean the area, clearing away any debris or loose material.

METAL SURFACES

The surface should be cleaned by applying our DILUYENTE TEC-4U solvent to ensure fast evaporation and drying. In the areas with overlaps, or the finishes of mechanical roof elements, we recommend using TECNOBAND 100 and/or DESMOSEAL MASILLA-PU putty to absorb the mechanical loads that are generated in this type of roof (ask our technical department).

Please contact Tecnopol Sistemas´ technical department if you have any queries about other types of substrate (fiber cement, wood, asphalt, ...).

3. Primer

You should also apply one of our primers (see table a) to increase adhesion to the substrate and achieve a correct surface finish. It can be applied by brush, roller or an airless spray.

In the case of concrete surfaces, the concrete should have completed the 28-day curing process after casting. You should also check that the degree of moisture in the surface of the substrate does not exceed the maximum allowable level of the product.

DRYING

To check the primer has dried, touch it with your fingertips. The drying time varies between 1 to 6 hours, depending on the primer used, the ambient temperature, and the temperature of the substrate.

The primer loses its properties 24 hours after it has been applied, which means that if more time has elapsed the substrate will have to be repainted. It will also have to be repainted in the event of rain.

4. Tecnocoat P-2049 waterproofing membrane

Apply TECNOCOAT P-2049 in a uniform way with a high-pressure sprayer (Reactor E-XP2), which can mix the two components at a pressure of 2.700 psi at 75ºC.

DRYING

• Drying tact time: 2 ~15 seconds
• Pedestrian traffic resistance: 3 minutes
• Wheeled traffic resistance: 12 hours
• Max. time between layers: 48 hours*

* If you want to apply a second coat of TECNOCOAT P-2049 and more than 48 hours have elapsed since the first coat of TECNOCOAT P-2049 was applied, the surface should be sanded and cleaned, and a primer coat of PRIMER epw-1070 applied.

5. Top coat (optional)

After the TECNOCOAT P-2049 membrane has been applied a protective coat of TECNOTOP aliphatic polyurethane varnish (see table b) should be applied within 24 ~ 48 hours, to ensure the stability of the desired colour when there is no additional protection. TECNOTOP is also good for surfaces with heavy vehicle traffic, and essential for non-slip finishes and waterproofing swimming pools, aquariums, water tanks etc...
