## Question

What is dressing of stone? Why is dressing (surface dressing) carried out?

## Short answer

Dressing shapes quarried stone to required size and finish using cutting tools. It ensures proper fit, thin mortar joints, uniform load distribution, improved appearance, and removal of weak or irregular parts, and makes stones easier to handle and suitable for arches or carvings.

## Answer

**Dressing of stone** is the process of giving the required shape, size and surface finish to the quarried stone blocks by cutting and chiselling with hand or machine tools.

#### Why dressing is carried out
1. To obtain the **required shape and size** so that stones fit properly.
2. To get **even beds and joints**, thin mortar joints and uniform load distribution.
3. To give a **good appearance** by smooth, plain or ornamental finishing.
4. To remove irregularities, cracks, loose and weak parts.
5. To make stones easy to **lift, handle and transport**.
6. To make stones suitable for special work like arches, cornices and carvings.

#### Surface finishes (common types)
- Rough tooled, chisel drafted, furrowed, punched, boasted, sunk and polished finish.

It is done using chisels, hammers and mallets, or by sawing, planing and polishing machines in factories.

1. Dressing of stone means:
   A. Giving required shape, size and surface finish by cutting and chiselling
   B. Quarrying stone by blasting
   C. Applying paint to stone
   D. Washing stone with acid
   Answer: A. Dressing is the shaping and finishing of quarried blocks by hand or machine tools. (Key point: Definition)

2. Why are even beds and joints obtained by dressing?
   A. To make stones heavier
   B. For thin mortar joints and uniform load distribution
   C. To increase porosity
   D. To avoid use of mortar completely
   Answer: B. Even beds allow thin joints and spread load uniformly. (Key point: Purpose of even beds)

3. Which is also a purpose of dressing?
   A. To increase water absorption
   B. To make stone softer
   C. To make stones easy to lift, handle and transport
   D. To create natural bed
   Answer: C. Dressing removes irregular and weak parts and gives handy shapes. (Key point: Handling)
