Hot-spray: Polyurea Rayston (pure polyurea), Polyurea Rayston P, Fast and A, Impermax Polyurea H (hot-spray hybrid polyurea), Impermax Polyurea H Flex, Rayston Fire E, Rayston Spray D50. These need the spray machine the catalogue lists.

Cold-applied: Impermax (one-component moisture-cured polyurethane, 1K PU), Impermax ST, QC, Evolution and A. Also Impermax Cold Polyurea (ETE 17/0509), roller-applied. Impermax Cold Polyurea Supreme is the solvent-free 2K polyurea written when a projection machine is not available.

However, a large dead-flat roof can still be cold-applied. A vertical stand usually is not. Stadium spectator terraces schedule hot-spray plus Rayston Fire E. A balcony may schedule Impermax 1K. Also, do not invent consumption. Read the current TDS, then the calculator.

First, name the geometry. Then name the commercial product and the chemical type in the same sentence. After that, name the machine or the roller. See Polyurea Rayston, Impermax, Impermax Cold Polyurea and industrial roofs — expansive polyurea.

Outbound reference: EOTA.

A missing spray machine is a reason to name Impermax Cold Polyurea Supreme. It is not a reason to rename a hot-spray.

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.
