An insulating high-build bitumen compound based on asphalt mixtures with wax and elastomeric additives. Black in colour. Once dried, it creates a flexible and soft layer that provides excellent surface insulation against water, sea water, waste water, etc. It protects the chassis against small stone and gravel impact, and against corrosion resulting from the use of water solutions for de-icing and the prevention of glazed frost in the winter season. It reduces sound level while the vehicle is in motion. BITUM SPRAY protects wooden parts against water. It may be applied on the underwater parts of wooden boat hulls and on the underground parts of fence posts. It guarantees the insulation of metal structures, foundations and underground concrete pipes against environmental impacts.
