Functions of paint
Short answer
Paint shields surfaces from moisture, prevents corrosion and rot, and provides decorative colour. It hides defects, eases cleaning, improves light reflection, and increases durability.
What are the functions (significance) of paint in construction works?
Paint is a coloured protective coating applied in liquid form on a surface that dries to a hard film. Functions in construction:
- Protection: Shields wood, steel and plaster from moisture, rain, sun, and chemical attack.
- Prevents corrosion and decay: Forms a barrier against air and water, stopping rusting of steel and rotting of timber.
- Decoration: Gives colours, smoothness and attractive finish to interiors and exteriors.
- Hides defects: Covers minor surface irregularities and stains.
- Hygiene and cleaning: A smooth film is easy to wash and does not harbour dirt or germs.
- Light reflection: Light shades improve lighting inside rooms; special paints reflect heat.
- Special uses: Marking and signs (road marking), fire-retardant, waterproof and anti-fungal coatings.
- Durability: Increases the life of the structure and lowers maintenance cost.
