Sports pavilion cool roof Polyurea Rayston
Sports-pavilion roof. Polyurea Rayston (hot-spray 100% pure polyurea) is the named membrane.
Krypton ProLine PU AL Primer (one-component polyurethane aluminium primer) is recorded on pipes. Polyurea Activating Primer is the field primer. White Colodur (single-component aliphatic polyurethane topcoat) is the cool-roof sealer.
The recorded build
Spray Polyurea Rayston as the continuous waterproof layer. White Colodur is the solar-reflective sealer.
Catalogue 2026 lists Polyurea Rayston for roofs and Colodur as an aliphatic topcoat. Do not substitute a hybrid polyurea on this pure-polyurea clause without a written change. Read consumption from the current sheet, then the calculator.
How to specify a sports-pavilion cool roof
Name pipe primer, field primer, hot-spray pure polyurea and white aliphatic sealer as four lines. Keep Krypton ProLine PU AL Primer on metal pipework; it is not the field primer. White Colodur is a finish, not the waterproofing.
