## Question

Write the function of painting work.

## Short answer

Painting works protect surfaces from weather, moisture, and corrosion; provide decorative colour and texture; ensure hygienic, easy-to-clean surfaces; and extend material life. They also improve light reflection and can offer fire resistance and safety colour coding.

## Answer

The functions of painting work are:

- **Protection:** protects surfaces from weather, moisture, rust, rot, insects and chemical attack.
- **Decoration:** gives colour, texture and a pleasant appearance.
- **Hygiene:** gives smooth surfaces which are easy to clean, preventing dirt and germs.
- **Preservation:** increases the life of wood, steel and plaster.
- **Light reflection:** light colours improve room brightness.
- **Identification and safety:** colour coding of pipes and signs.
- **Other uses:** fire resistance, heat reflection, damp resistance.
