Rust-Oleum Dac Hydro Alu is a water based, solar reflective coating for aluminium roofs. Provides lasting protection and decoration of metal and most bituminous product roofs.

Prevents strong warming up of the surface locally by the light reflecting effect of the aluminium flakes in the coating film - keeps its aluminium finish even in strongly varying atmospheric conditions (U.V. rays, water, strong temperature fluctuations, etc.) 

  • Heat reflecting
  • Excellent resistance to water
  • Optimal resistance to extreme weather effects and changes in temperature
  • Abrasion resistant rubberlike coat without joints or seams
  • Lasting finish; aluminium particles bound in paint
  • Vapour permeable
  • Can be used as a topcoat on Dacfill
