Dacfill HZ is a 2 component waterproofing product based on waterdispersed acrylic resins

Dacfill HZ is a 200% elastic quick-drying water-resistant flat roof paint suitable for horizontal roofs and can be applied on almost any substrate
Dafill HZ is resistant against stagnating water 1 hour after surface drying. It has excellent resistance against extreme variations in temperature, atmospheric pollution and UV rays. It builds an abrasion resistant rubberlike coat without joints or seams, which is hardly flammable and self-extinguishing. 

Recommended Uses

Waterproofing protection of flat roofs. Also applicable in situations where quick water resistance or recoatability is required.


Theoretical: Per coat: 1 - 1,5 kg/m² (dependent of the substrate). To be applied in 2 coats

Surface Preparation 

The substrate must be well clean and dry, free from flakes, gravel, dust and dirt. Fill up joints with Elastofill, bridge active cracks with "Dacfill Bridging Mesh" and apply one of the following priming coats: 
  1. On porous concrete, hard PVC and polyester: Primer 44HS
  2. On very smooth concrete: Noxyde diluted with 25% water.
  3. On iron and steel: undiluted Noxyde
Roofing or bituminous materials over 1 year old can be coated directly with Dacfill HZ depending on its condition. To ensure optimal adhesion it is recommended to fixate the substrate with Parafix. Zinc, galvanised steel, copper, lead and aluminium can be recoated with Dacfill HZ, if required, after degreasing and slight sanding.
