Ponding is a design condition
Notas de ingeniería. No un blog. Ponding is a design condition. A UV acabado does not rescue a dead-flat roof. Therefore the specification must name the exposición before the membrana.
When ponding is a design condition, not a defect
Catalogue 2024 writes Impermax Aqua and Impermax Aqua 2K for wet rooms and water-retaining structures. Polyurea Rayston (pure poliurea) carries WRAS where drinking water is the exposición. Blue-roof language in the catalogue sits with Impermax Cold Polyurea (ETE 17/0509).
However, do not move a WRAS or ponding claim onto a membrana the catalogue does not mark that way. Impermax (monocomponente moisture-cured poliuretano, 1K PU) is not automatically an immersion lining. Also, a pond photograph is not a roof card.
If the roof will pond, say so in the specification. Then pick the application page that matches the exposición. After that, read consumo from the current TDS, then the calculadora.
Where this site sends the reader
See indoor wet rooms, ponds and artificial lakes, and Polyurea Rayston. Documentos: /documents/.
Outbound reference: CEN-CENELEC — EN 1504 family.
A dead-flat roof without that clause is still a ponding risk. Write the exposición before the product name.
Therefore the current TDS remains the source for mix ratio, overcoat and consumo. Then the calculadora sizes the area. However, a number invented here would be a specification error. In addition, the application page is the schedule. First name the exposición. 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 ficha vigente, then the calculadora.
