How do you measure plaster wall thickness?
The actual thickness will vary at different locations on the wall and within a single sample. To further support the variation in thickness, the code calls for the plaster thickness to be measured from the back plane of the plaster metal base (essentially face of framing) outward and not the actual thickness of cement.
What plaster do I use for skimming?

What is the minimum thickness of external plaster?

Recommended thickness of plastering for brick walls is 12 MM, 15 MM or 20 MM. 12 MM thick cement plaster is done where the plain surface of brick masonry is plastered. 15 MM cement plaster is required on the rough side of 9” and 4.5” wall.
What is wall thickness?
Wall thickness is defined as the distance between one surface of the 3D model and its opposite surface. It is the required thickness that a 3D model should have. Since many 3D printing problems are caused by inappropriate wall thickness, it is important that the wall thickness of the 3D model is assigned correctly.
How thick is two plaster coats?
What thicknesses are plasters applied? Undercoat plasters are usually applied at 11mm and most finish coat plasters are applied at 2mm.
Do all plaster walls have lath?
Like their earlier counterparts, modern plaster walls are created by smoothing plaster over lath (usually metal lath designed to hold plaster).
