Acrylic Primer HS 4:1



Bicomponent acrylic filler with high solids content. Characterised by very filling properties, very high adhesion, good stability and good levelling on vertical surfaces. Very easy to apply.


  • Easy to mix and apply.
  • Short hardening time.
  • Good isolating and filling properties.


Acrylic fillers  can be applied over:

  • Bare steel and aluminum after matting and degreasing.
  • Sanded glass fibre (GFK/GRP).
  • Polyester
  • Wash primers.
  • acrylic fillers.
  • Epoxy fillers.
  • Old finishes in good condition after flatting and degreasing.

Well prepared surface is necessary for achieving best results. Following sandpaper gradations are recommended:
