WHAT SHOULD BE THE THICKNESS OF PLASTERING?

Thickness of Plastering

Finishing coats (and single-coat work, where employed) should be of such minimum thickness as just to provide a sufficient body of material to harden satisfactorily under the site conditions in any particular case.

The total thickness of two-coat work exclusive of keys or dubbing out shall be generally about, but shall not normally exceed 20 mm and it shall not exceed 15 mm in the case of in situ concrete soffits. The thickness of three-coat work shall be about, but shall not normally exceed 25 mm.

The recommended thickness of an individual coat for different no. of plaster coats is as follows.

10 to 15 mm
