This document discusses general maintenance of buildings, focusing on painting of buildings and home electricity systems. It provides details on different types of paints used for plastered walls, wood works, metal works, and other surfaces. It also discusses improvements made to electrical systems, including replacing fuse-wire systems with Miniature Circuit Breakers and installing Earth Leakage Circuit Breakers to prevent fires. Key points are provided on maintaining electric systems in buildings, such as using quality copper wires, avoiding overloads, installing ELCBs, and reducing moisture and damage.

4. 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.

8. 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• The fuse-wire system in the old buildings has now been replaced by the automatically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.

9. 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.

11. Points to be considered inPoints to be considered in
maintenance of Electric System in amaintenance of Electric System in a
Building: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.

12. 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.
