Print Friendly, PDF & Email
  • ALÇITEK is bagged gypsum-based, ready-to use spray plaster.
  • ALÇITEK can be directly applied on brick, concrete, aerated-concrete, etc.
  • In one layer, it prepares the surface ready to pain. There is no need for satin finishing gloss plaster.
  • It can be applied at details such as window and door fronts with hand mix, without any problem.
  • It has a high surface hardness and brilliant appearance.


  • Dust and substances preventing adherence on the surface must be cleaned before the application.
  • Make segmentation on the surface by using segment laths.
  • Mix ALÇITEK by a plastering machine and spray it between segments. After spraying, smooth the surfaces by using a straight edge.
  • In about half an hour time before the surface hardened, smooth the surfaces again by using a straight edge if required.
  • Make pre-smoothening with spatula. Wet the surface and apply sponge.
  • Approximately 10 minutes later, using a steel trowel get a brilliant, hard and glazed surface.
