Download Technical Specification Sheet Download Health and Safety Sheet
Dacfill is a waterproofing product based on waterdispersed acrylic resins. 

Product Information:

  • Elastic
  • 100 % waterproof
  • Vapour permeable
  • Excellent resistance against extreme variations in temperature, atmospheric pollution and UV-rays. 
  • Builds an abrasion resistant rubberlike coat without joints or seams, which is hardly flammable and self-extinguishing. 
  • Additionally it can be reinforced mechanically with Dacfill-Fleece.


  1.  Consumption per coat: 0,6 - 1,5 kg/m² (dependent of the substrate). 
  2. Steep roofs (without fleece): 1,3 - 2,5 kg/m². 
  3. Roofs with a little slope (with fleece): 2,5 - 3 kg/m² (water stagnation). 
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 well clean and dry, free from flakes, gravel, dust and dirt. Fill up joints with Elastofill, bridge active cracks with "Dacfill Bridging Fleece" and apply one of the following priming coats: 
  • on porous concrete, hard PVC and polyester: Primer 44HS 
  • on very smooth concrete: Noxyde diluted with 25% water 
  • on iron and steel: undiluted Noxyde
  • Roofing or bituminous materials over 1 year old can be coated directly with Dacfill
  • Zinc, galvanised steel, copper, lead and aluminium can be recoated with Dacfill, if required, after degreasing and slight sanding.
