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
- 400% elastic

Surface Preparation: The substrate must be well clean, free from peeling, dust and dirt. Bridge cracks and fissures with Dakfill-mesh. Fill up joints with Elastofill. Very porous substrates have to be primed first with Primer 44HS.
Typical Paint System
Dac-Hydro-Alu can be directly applied on metals (except new galvanised steel), roofing and most bituminous products (>1 year).
Dac-Hyrdo-Alu can be applied without any problem on most waterbased products like Dacfill and Noxyde.
Typical Use: Waterproofiing protection of flat roofs. Also applicable in situations where quick water resistance or recoatability is required.
Application: Brush: Square brush. Do Not dilute.
Roller: Roller with long hairs (long nap). Do not dilute.
Air-atomised spray: Not applicable
Airless spray: Nozzle: 18-23 / Pressure: 220 bars. Do not dilute
Drying weather: enough air ventilation (light breeze) or sunny conditions.
Min. Temperature: 5°C.
Max. Relative humidity: 80%.
