Application of the fire-retardant plaster should be carried out on walls and chimney flues, on walls adjacent to wood-burning cookers and cookers and around fireplaces built into the wall. The drying process of the plaster can be accelerated by additionally heating the room in which it is laid on the walls. If the Vitcas smoothing coat is applied directly onto Vitcas CS fireplace boards or Vitcas HT high-temperature boards, care must be taken to ensure that the surface of the boards is rough.
