- After relasing the mixing ball, shake well before use.
- Sand the surface and clean and degrease with Safety Clean and/or Multifoam.
- Apply Novafill Flex 2 in a serie of thin layers, allowing a brief drying period between layers.
- Once dry (20 min) sand before applying paint. Sanding may be done dry (500 grit) or wet (800 grit).
- Empty the nozzle spraying with the can upside down.
After drying (+/- 15 minutes), Novafill Flex 2 can be sanded (both wet and dry). Can be painted over after 2 hours with the most common paints. With plastics that contain PE or PP, Novafill Flex 2 may have less good or even poor adhesion. The use of Seal & Bond Special Primer can considerably improve adhesion.
Which type of Novafill Flex to use?
As a first layer on metal: Nova Finish Primer, with its corrosion-resistant properties.
As a first layer on other substrates (e.g. synthetic materials): Novafill Flex or Novafill Flex 2, with their adhesive properties (on difficult plastics first apply Seal&Bond Special Primer).
Subsequent layers according to the requirement for filling: Novafiller, Novafill Flex or Novafill Flex 2.
Nova Finish Primer is recommended as a final layer prior to painting because of its fine structure: easier finishing and time savings due to reduced requirement for sanding.
