The thickness of plastering provided for the underside of R.C.C. work is 6 mm. The typical thickness of cement plaster is 13 mm, though it can occasionally be 19 mm thick as well. Two components are required for 19 mm plaster. The first layer is 13 mm thick, while the second is 6 mm thick. The second layer's cement slurry is placed after the first layer has had time to harden.

Workflow for Plastering

Surface preparation, the groundwork for the plaster, application of the undercoat or base coat, application of the finishing coat, and curing of the plastering work is the Workflow for Plastering.

Aftercare of Plastering:

  • After the work is finished, the floor area, doors, or door frames need to be cleaned.
  • As soon as the plaster has properly solidified, curing should begin, and curing must last at least seven days.
  • The plaster must be let to cure for 24 hours before it may be removed.

Summary:

What is the thickness of plastering provided for the underside of R.C.C. work? (a) 6 mm (b) 12 mm (c) 20 mm (d) 3 mm

Plastering for the underside of R.C.C. work has a 6 mm thickness. Along with the walls, the ceiling (lower portion of the roof) also needs to have plaster applied to it. If holes are discovered in the ceiling when the shuttering is opened or if it is not smooth in some places, a 6 mm plaster is applied in a 1:3 ratio of cement to sand. Its treatment is carried out in the same way.
