PAINTING OF BUILDINGPAINTING OF BUILDING

1. Painting of Buildings:1. Painting of Buildings:• A substance composed of solid coloring matter suspended in a liquid

medium and applied as a protective or decorative coating to various surfaces, or to canvas or other materials in producing a work of art.

• Painting is a very important and costly activity for the maintenance of buildings. Different types of paints are used for painting different parts of a buildings.

• Nowadays, people have become more conscious of beauty, brightness, aesthetics, etc. moreover, today’s buildings tends to be tall and we need more durable paint for these buildings. Many people want luxurious settings in their buildings. Paint industry has also risen up to exploit this demand.

2. Home Electricity System:2. Home Electricity System:

• The life of electrical installations in a building is very less as compared to those of structural elements. A lot of improvements have been made in the modern electrical devices to make electric supply more safe.

• For example,• The fuse-wire system in the old buildings has now been replaced by the automatically

operating Miniature Circuit Breakers (MCB) system.

• Another improvement is the installation of the automatic Earth Leakage Circuit Breaker (ELCB) which switches off the current if there is even a small leakage in the electrical circuit.

Conti…..Conti…..• Most of the fires reported in old buildings could have been avoided if the

ELCB devices were installed in their electrical system.

• The new electrical wiring of a building is assumed to serve for 20 to 25 years only without any trouble. After this service, the system should be checked regularly for its good performance.

Points to be considered in Points to be considered in maintenance of Electric System in maintenance of Electric System in a Building:a Building:1. Use good quality cooper wires for all electrical wiring.

2. Do not overload any of the circuit by using too many appliances in one circuit.

3. Do not use more than 12 A to 15 A fuse in each of the ring circuit.

4. Do not use lamps of very high wattage. Use of modern fluorescent lamps saves electricity considerably as compared to filament lamps.

5. Avoid moisture from all the places near the path of the electric wiring and near electric boards.

Conti…..Conti…..6. ELCB should be used in a circuit, so that current is switched off, if there is

any leakage in the circuit.

7. Do not use damaged or worn-out extension cords.

8. Use star rated A.C., refrigerators to reduce the consumption of electricity.
