Cold 1K PU is rolled or sprayed as a liquid that cures with air moisture. Impermax (one-component moisture-cured polyurethane, 1K PU) is that family. Cold polyurea is a different rheology. Impermax Cold Polyurea (ETE 17/0509) is roller-applied. Hot-spray polyurea gels in seconds. Polyurea Rayston (pure polyurea) and Impermax Polyurea H (hot-spray hybrid polyurea) are written for large, irregular or vertical work.

Football stadium stands schedule Rayston Fire E (aliphatic fire-rated finish, Euroclass Bs2d0) because the catalogue writes that class for the bleacher membrane. A self-levelling floor body is a different liquid again. Pavifloor / Pavisoft (resin floor body), Raycrete SL and Polyurea H SL must not borrow the stadium photograph.

However, do not swap a 1K roof membrane onto a vertical stand because the viscosity felt similar on another job. Pick the membrane the application page already schedules.

First, name the geometry. Then name the chemistry. After that, read consumption from the current TDS, then the calculator.

See football stadium stands, Rayston Fire E, and Impermax Cold Polyurea.

Outbound reference: EOTA.

A roller on a vertical stand is not a specification. Match the liquid to the geometry.

Therefore the current TDS remains the source for mix ratio, overcoat and consumption. Then the calculator sizes the area. However, a number invented here would be a specification error. In addition, the application page is the schedule. First name the exposure. Next name the commercial product and the chemical type in the same sentence. After that, open documents. Also keep the finish on the same clause as the body. A sample, a colour or a photograph does not replace that sentence.

These notes do not replace the current TDS, SDS or a written specification. For pack sizes, mix ratio and kg/m², read the current sheet, then the calculator.
