Impermax Aqua 2K (solvent-free two-component polyurethane) is written for water-retaining structures. Polyurea Rayston (pure polyurea) is the name the applications page uses for tanks and pools. WRAS on Polyurea Rayston is the drinking-water mark in Catalogue 2024. A pool is not automatically that exposure.

A rooftop pool still has to move with the deck. Crack-bridging and the finish against UV belong in the same clause as the tank. Paintchlore is the catalogue aliphatic for chlorinated water where the sheet names it. However, do not use the stadium photograph for a pool.

Also, do not use a flooring chapter image for a waterproofing tank. Mass, insulation and the structural check stay with the project. kg/m² of membrane stays on the current TDS. Then use the calculator.

This note will not invent a build-up mass for lightweight rooftop pools. Read the current TDS, then the calculator.

See swimming pools, waterparks, and Impermax Aqua 2K.

Outbound reference: CEN-CENELEC.

A rooftop pool still loads the structure. That check is the project’s, not a TDS kilogram line.

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.
