Impermax Poliurea H Supreme for roofs that move
Notas de ingeniería. No un blog. Impermax Poliurea H Supreme is a high-elongation hybrid. It is not H Flex and not pure poliurea.
Keep Impermax Poliurea H Supreme on poorly settled or moving roofs. Krypton magazine NUM.5 (October 2025) cites a new ETE for roof waterproofing on this hybrid. Elongation at break is written above 650 percent. Therefore the specifier does not collapse H, H Flex and Supreme.
What Impermax Poliurea H Supreme actually carries
NUM.5 calls it a versatile hybrid poliurea for structures that are poorly settled or under significant movement. Hail is evaluated to European standard EN-1358 with results the magazine calls excellent. Catalogue 2024 already lists Impermax Poliurea H Supreme as a proyectado en caliente hybrid of very high elongation, with CE EN-1504-2. NUM.5 also records EPDs (ISO 14025) for Rayston Fire E, Impermax 2K, Impermax Poliurea H and Poliurea Rayston. That EPD list does not name Supreme. Do not move those EPDs onto this card.
H Flex carries EAD-030675 21/0740 for bridge decks. H carries ETA 11/062. Pure Poliurea Rayston carries ETA ETAG005 16/0148. Keep those marks on those names. Supreme is the high-elongation hybrid the magazine tests for hail.
However, 650 percent is an elongation figure, not a consumo. Read kg/m² from the current TDS. Do not invent a rate here.
Cómo especificar Impermax Poliurea H Supreme
First, name a roof that moves. Then name Impermax Poliurea H Supreme and proyectado en caliente hybrid poliurea in one sentence. After that, cite the roof ETE and EN-1358 as the magazine prints them, plus CE EN-1504-2 from Catalogue 2024. In addition, size the area on the calculadora.
See Impermax Poliurea H Supreme, cubiertas, balcones y terrazas, airport roofs, and documentos. Area: calculadora.
Outbound reference: EOTA — European Technical Assessments.
A hail clause is not a bridge EAD. Keep Impermax Poliurea H Supreme on the name that carries the elongation.
Therefore the current TDS remains the source for mix and overcoat. First name the movement. Next name Supreme. After that open documentos. Also keep H Flex off this hail clause unless the job is a deck.
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 calculadora.
