Colourless insulating and sealing primer

  • Fast drying
  • Does not attack polystyrene
  • Good insulating and sealing effect
  • Non-yellowing

The Kronen-Isolierspray farblos 122 (or Kronengrund® 121 for the paintable version) offers a versatile solution for insulating and priming work. In interior applications, it is used to prepare absorbent materials such as wood, plasterboard, lime plaster or concrete to ensure even recoatability. At the same time, it reliably insulates light contamination from nicotine, crayons or water stains.

For outdoor applications, the product is suitable for shielding bitumen or tar residues and for preparing mineral substrates. As a protective layer, it permanently seals emulsion paints and wallpaper against dirt. Prior to use, a preliminary test is recommended to individually check the material compatibility and opacity.
