Question

The final coat of plaster is known as ___________

(a) Background

(b) Finishing coat

(c) Undercoat

(d) Plastered coat

This question was posed to me in an interview.

The doubt is from Terminology Used in Plastering Work in section Pointing and Plastering of Construction & Building Materials

Answer 1

Right answer is (b) Finishing coat

For explanation I would say: The final coat of the plaster applied to the walls and ceilings is called the finishing coat. This coat is also called skimming coat or setting coat. Painting cannot be done until the finishing coat is applied.
