Finished internal wall thickness

[akist]

Hello,

Using internal walls build of concrete blocks which (I think) are 100mm across, and the door linings are 138mm, which implies 100mm wall plus 19mm of plaster on each side. The 19mm plaster is made of a 15mm base and 2-3mm finishing plaster.

Am I correct ?

You can get different widths of liner, 8-10mm base coat for wet plastering is standard.
