    We need more information and a picture would be necessary. There is supposed to be a gap between the door jamb and the rough opening. Shims are used to fix the jamb in the rough opening. This leaves gaps all around between the door jamb the rough opening which are then covered by finish trim called casing. Mar 16, 2018 at 1:45

  • @MichaelKaras, should be cement, and oil-based paint painted on it.

  • use a cement filler product. The problem you might have is with expansion of the frame, but maybe not.

  • @Ken, can I also use normal putty to fill the gap?

For small gaps between wooden trim such as doorframes and plastered walls I use a "Flexible gap filler" - available at any DIY store. Spending a few minutes reading the containers carefully and asking store assistants will get you a product you can try.

Description from a randomly selected product

This flexible filler achieves a white crack-free fill between two surfaces where movement can occur. Controlled application is ideal for long linear gaps.

  • For flexible, crack-free filling between two surfaces where movement can occur.
  • Easily controlled application for long linear gaps.
  • For indoor and outdoor use.

Another one

An acrylic filler for draught proofing and filling fine cracks. Can be sanded, overpainted or papered over. Solvent free formulation.

  • Interior or Exterior Use: Interior
  • Application Method: Knife
  • Colour: White
  • Size: 310 ml
  • Type: Ready Mixed Filler

It is often a good idea to rake out the corner first, to remove loose or weak paint. Then sand as necessary before cleaning and filling.
