🔬 Understanding Plastering and its Terminology
The question asks for an alternative name for the process of plastering. While "plastering" is the most common term in modern construction, older, more traditional terms are still used and are important to know.
Pargeting: An older term for plastering. It traditionally refers to decorative or ornamental plasterwork, especially on exterior walls, but it can also be used more generally to mean the application of a plaster or mortar coat. In some contexts, it specifically refers to the plastering of the inside of a chimney flue.
⚖️ Detailed Analysis of the Options
Let's evaluate each term to find the correct synonym for plastering.
(b) Pargeting
Why it's correct: As defined above, pargeting is a historical and technical synonym for plastering. It is the correct answer.
(a) Pre-casting
Why it's incorrect: This refers to the process of casting concrete elements (like beams, slabs, or wall panels) in a factory or yard before transporting them to the construction site for erection. It is a method of concrete construction, not a term for plastering.
(c) Porting
Why it's incorrect: This term is primarily used in engineering to describe the process of modifying the intake and exhaust ports of an engine to improve airflow. It has no relation to construction or plastering.
(d) Polishing
Why it's incorrect: Polishing is a finishing process used to create a smooth, glossy surface by rubbing it with fine abrasives. While some special plaster finishes can be polished, polishing is a final treatment and not the same as the initial application of the plaster itself.
📋 Additional Information on Plastering Standards
Understanding the standard practices for plastering is essential for quality control and estimation.
- Unit of Measurement: Plastering work is measured and paid for by area, in square meters (m²).
- General Thickness: For most internal walls, a single coat of plaster is typically 12 mm to 15 mm thick, often using a 1:6 cement-sand mortar.
- Ceiling Thickness: To reduce weight, ceiling plaster is applied thinner, usually around 6 mm, with a richer 1:3 mix for better adhesion.
- Rules for Deductions: For measurement purposes, standard rules apply to openings. No deduction is made for the area of small openings (up to 0.50 m²) or for the ends of beams, joists, and rafters that are embedded in the wall (up to 0.50 m²).
