Neuchâtel Mastic Asphalt Flat Roof System

In cases where Neuchâtel Mastic Asphalt is used solely for roofing surfaces with minimal or no traffic, it is applied in two coats, each with a nominal thickness of 20mm. The initial coat is laid to a depth of 10mm, followed by the second coat of the same thickness. The liquid form of mastic asphalt allows it to be spread evenly, creating a smooth and seamless surface that can be shaped to fit any required form or surface. To provide additional protection, it can be coated with solar-reflective UV-resistant paint.
