Solar Reflective Roof Paint

Download Technical Specification Sheet Download Health and Safety Sheet
Dac-Hydro-Alu is a roof paint based on water dispersed acrylic resins. It prevents strong warming up of the surface locally by the light reflecting of the aluminium flakes in the coating film. It keeps its aluminium finish even in strongly varying atmosphere conditions. It's recoatable and builds an abrasion resistant rubberlike coat without joint or seams.


Theoretical: Waterproofing = 1 - 1.5m2 per litre (depending on roof type) as a second coat on Dacfill. Esthetical = 0.3 - 0.5m2 per litre.
Practical: Practical coverage depends on many factors such as porosity and roughness of the substrate and material losses during application.

Surface Preparation

The substrate must be clean, free from peeling, dust and dirt. Bridge cracks and fissures with Dacfill-Mesh. Fill up joints with Elastofill

Very porous substrates have to be primed first with Primer 44HS.
Dac-Hydro-Alu can be directly applied on metals (except new galvanised steel) roofing and most bituminous products (> 1 year).
Dac-Hydro-Alu can be applied without any problem on most waterbased products like Dacfill and Noxyde.
Do not apply directly on Fillcoat or Fillcoat Fibers. In this case it necessary to apply first a coat of Dacfill.
Dac-Hydro-Alu cannot be applied on flexible PVC, EPDM, tar or bituminous materials < 1 year, polyisobutylene and smooth bitumen-polymers.
In case of stagnating water, Dac-Hydro-Alu must always be applied in combination with the Dacfill-Mesh with a consumption of 2 l/m2.
