100% pure polyurea membrane for waterproofing and protection

• Great mechanical resistance
• Classification W3, 25 years of useful life
• Valid contact with drinking water
• Waterproofing of bridge decks

AplicaPROOF PUA P is a dual-component sprayable aromatic coating, suitable for waterproofing, protection and sealing. It is composed of two highly reactive liquid components, isocyanates and amines, which are mixed using our specific spraying equipment, to form a solid, continuous, watertight and waterproof pure polyurea membrane, without joints or overlaps, with high mechanical and elongation qualities.
It is CE marked on the basis of a Declaration of Performance (DoP) drawn up in accordance with EU regulation 305/2011.


For the waterproofing and protection of:
• Flat walkable roofs, terraces, balconies and pitched roofs.
• Inverted roofs (bottom insulation).
• Floors and decks with vehicular traffic, slip resistant finish (CTE SUA 1, Class 3 ENV 12633:2003).
• Drinking water tanks and irrigation canals (WRAS and RD 140/2003,98/83/CE).
• Bridge overlays (under asphalt), and elements of the civil sector (guide 033, ETE in force).
• Industrial flooring with requirements for impermeability and mechanical resistance (EN 1504.2).
• Concrete slabs, retaining walls and foundations (EN1504.2).
• Roof gardens (P4:TH4, ETE in force).
• Power plants, recycling plants, petrochemical plants, waste water (EN1504.2).
• Swimming pools, aquariums, ponds, even marine environments.
• Vehicle and boat coatings.
• Pitched or flat roofs of corrugated fibre cement, asbestos or similar.
• Protection of polyurethane foam thermal insulation systems.


It comes in two sizes of product kits:
- Metal drums of 225 kg each (Component A: isocyanates and Component B: amines).
- Metal drums of 60 kg each (Component A: isocyanates and Component B: amines).

Safety and hygiene

These safety recommendations during handling are necessary during the execution process, as well as in the processes before and after the execution in situations of exposure to machinery under load.
• Respiratory protection: When handling in aerosol form, an approved air-purifying respirator must be worn.
• Skin Protection: Wear rubber gloves. Remove immediately after contamination. Wear clean clothes that cover the whole body. Wash thoroughly with soap and water after work and before eating, drinking or smoking. Contaminated clothing should be washed and/or dry cleaned.
• Eye/face protection: Wear safety goggles to avoid splashing and exposure to spray mist.
• Waste: Waste generation shall be avoided or minimised. Incinerate under controlled conditions in accordance with local and national laws and regulations.
• In any case, please refer to the existing product safety data sheets, which are publicly available.

Aplication requirements (projection equipment)

For formation, it is necessary to mix the two initial liquid components, isocyanates and amines/polyols, by means of the spraying equipment (proper maintenance and cleaning of the spraying equipment is recommended).
The most general parameters of this equipment shall be the following:
• Isocyanate heater temperature: 70-75ºC
• Amine heater temperature: 70-75ºC
• Hose temperature: ±70ºC
• Operating pressure: 2,500-3,000 psi
• Recommended mixing chamber: use mechanical purge chamber.
These temperature and pressure parameters must be assessed, ratified or slightly varied by the application agent, depending on the conditions of each climatic zone, climatic situation or according to the specifications of the spraying equipment.


The recommendations for use are based on our knowledge and experience. The technical data have been obtained under normal laboratory conditions and may vary depending on the conditions of installation. As the conditions of application are beyond our control, the information in this sheet does not imply any liability on the part of the company.
