 INTRODUCTION
WHAT IS PAINT??
• The paints are coating of fluid material and they are
applied over the surface of timber and metals.

• Paint is a liquid composition after application it is convert

in to a solid film.

• Function of paint is :-
a) to protect the material from weathering, oxidation
process and damages
by insects.
b) to improve the beauty of the material.
c) To facilitate the cleaning process of the surface.

• Major companies of paint are :-

✓ Asian Paint
✓ Nerolac
✓ Berger
✓ Indigo
 TYPES OF PAINT
• Paints are categorized into seven groups:-

1) Oil paints

2) Synthetic paints

3) Emulsion paints

4) Cellulose paints

5) Varnishes

6) Water paints (distemper)

7) Special paints
OIL PAINTS

• These are the traditional type having a linseed oil medium.

• They are respectively termed as primes, undercoats and finishing

coats.

• This paint is cheap and easy to apply and it possess good opacity and
low glow.

• It consists of various coats:

1. Priming coat
2. Under coat
3. Finishing coat
 1. PRIMING COAT

• Linseed oil, white lead, a small amount of red lead and extender
(a white pigment used to increase bulk, prevent sedimentation
and improve spreading)
• The lead base is particularly suitable for external work.
• Leadless pigments are for internal use.

2. UNDER COAT
• Linseed oil, white lead(tinted if required) and has a high quality drying oil.

3. FINISHING COAT
• Oil varnish, pigments of desired colour and perhaps extenders, and
thinners; finishes vary from flat to oil-gloss.
 Synthetic Paints
• The medium for these is a chemical
compound, one type being an oil modified
alkyd resin.

• They have the advantages over oil paints

in setting more quickly and offering greater
durability where corrosion is a danger.

• They also have a better flow and are easier

to apply.

• Drying is by evaporation of the solvent, by

oxidation and chemical change.

• It is applied on the surfaces which may not

be completely dry, e.g. Fresh concrete.
 Emulsion Paints

• An emulsion paint has the pigments and the

medium dispersed as small globules in water.
• Oil , synthetic resin and bitumen are common
medium.
• The different emulsion paints are alkyd, bitumen,
polyvinyl acetate and styrene emulsions.
• They are used mainly on walls surfaces.
• Alkyd emulsion paints contain pigments, oil, and
synthetic resins, they give a flat finish.
• Bitumen emulsions are those of bitumen in water
plus pigments and extenders.
• They are for use on asphalt and bituminous
surfaces.
• Polyvinyl acetate(p.v.a.)emulsion paints have a
p.v.a. medium and give a finish from flat to egg
shell gloss.
• Styrene emulsions incorporate the synthetic resin
styrene in several forms and have a medium gloss.
Cement Paints
• This is the group of paint in which cement
is the main constituent besides a
colouring pigment in the powdered form.
These pigments also contain varying
proportion of hydrated lime, hygroscopic
salts and water repellent additives like
aluminium stearates.
• Cement paints are cheap, durable and
can be made highly decorative by using
selected pigments.
• Cement paints can be given on both
external & internal portion of the
buildings.
• It is used for painting exterior wall
surface mainly for preventing water
penetration and reductions of dirt
collection.
• It is suitable for coating concrete as well
as decorating indoor and outdoor walls.
• They are also available in different color
shades.
 Varnishes
• Varnishes are used to give a transparent
film to a surface.
• These are of two kinds- Oil varnish &
Spirit varnish.

OIL VARNISH:

• They contain linseed oil or other drying oils,

dryers, synthetic or natural resins and
solvents such as white spirit or turpentine.
• They dry by evaporation of the solvent and
oxidation of the oil.
• The relative proportions of the oil and the
resins control the usage, if the oil is
predominant a more elastic varnish reserved
for external work.
• If the solvent is the major ingredient a high
gloss, which dries out rapidly, is obtained for
internal work.
• Copal varnish is a good quality type.
SPIRIT VARNISH:

• Spirit varnish is a solutions of shellac

and spirit resins dissolved in
commercial alcohol(methylated
spirits).
• The are only suitable for internals
surfaces like furniture(e.g. in French
polishing).
• Polyurethane varnish is a type of
resin varnish producing a very
durable finish.
 Water Paints (Distemper)
• They are used mainly on internal walls and
ceilings and most of them give a flat finish.
• There are several kinds are prepared on the
site by adding water to make a paste.
• They have a drying oil or varnish medium
emulsified in water containing glue or other
fixatives.
• Barytes is a common pigment along with
tinting pigment.
• The cheapest type known as soft or ceiling
distemper, contains only a glue size vehicle
and tinted powdered chalk.
• It can be removed by washing or brushing
and so is only used for ceilings.
• Oil bound distemper is a better quality having
a mixture of linseed oil, pigment and
extenders.
• It will withstand limited careful washing.
 SPECIAL PAINTS
• There are many types of special paints :-

ALUMINIUM PAINTS:

• These are often used as a primer on resinous woods like

Columbian and Oregon pine because they have a good sealing
effect. 2.
• They contain aluminium powder in a quick drying medium.

ANTI-CONDENSATION PAINTS:

• These containing cork filler and whilst.

• They are not a substitute for adequate ventilation( the best
safeguard against condensation).
• They afford some relief by reducing the transfer of heat.

BITUMINOUS PAINTS :

• The vehicle for these are mostly bitumen.

• They provide a cheap method of protecting steel where
appearance is secondary.
CHLORINATED RUBBER PAINTS:

• This contains chlorinated rubber combined with

pigments and special thinner.
• The paints offer good resistance to acids and
alkalis and can be used where fumes from these
chemicals arise.
• They are suitable for internal use on brickwork,
concrete and steelwork.

FIRE-RESISTANT PAINTS:

• These are used to increase the resistance to fire of

wood and certain building boards.
• There are several proprietary types incorporating
ammonium phosphate.

FUNGICIDAL PAINTS:

• These include special ingredients which render

them resistance to mildew and other fungoid attack,
useful in humid surroundings.
HEAT-RESISTING PAINTS:

• They incorporate special varnishes

and pigment which do not discolor on
heating.

TEXTURE PAINTS:

• These contain different powders and

pigments with glue.
• They used in a stiff consistency to
make textured surface on which
patterns can be formed by brush or
special implements.

WOOD STAINS:

• It consists of various shades in oil,

spirit or water medium.

PRECAUTIONS
While painting , one must take a few precaution , such as:-

• Do not use cotton rags for cleaning , use soft synthetic or muslin cloth .
Otherwise , threads will stick to the surface leading to a patchy , uneven Cotton cloth
finish.

• Do not apply the next coat without the first one drying ,
otherwise you will have a wrinkly , patchy- finish as well as
loss of gloss.

Muslin cloth
• Do not use very hard Sandpaper , Otherwise there
will be scratches, roughness and poor gloss.
PRECAUTIONS
• Do not apply very thick coats , otherwise there will be thick rough finish ,resulting
in slow drying.

• Avoid mixing paints yourself, buy readymade paints as far as possible , otherwise there
will be patchy and inconsistent columns in the finish.
PROCESS OF WALL PAINTING
PRE-PAINTING

1. Identify the problems area like – Cracks , Dampness and prepare the surface:- surface
preparation is important because it directly affects the surface finish of the paints.
A paint , a putty knife or a sand paper is used to remove loose particles or flakes and the surface is
made enough and free from dust , dirt, grease etc.

2. Recitify the water seepage problem at source . This could mean

repairing leaking pipes or cracks in the exterior walls.

3. Scrap off old paints and dirt:- The old paints of the wall
Is always used to come out from the surface after a duration ,
check the loose plaster by tapping on the walls. A hollow sound
indicates the loose plaster, so we have to remove it with the help
of scrapper.
4. Plaster :- Allow newly plaster surface to mature for a
period of at least 6 months after the application of a coat , to
insure through drying of plaster.
PROCESS OF WALL PAINTING

5. Sand the surface:- After the process of scrap off the

Surface, we use sand paper to ensure that the surface is dry
and free from dust, dirt or grease.

6. Sealed the crack:- Cracked or flakes should be sealed

properly with sealant.
(- do not apply on wet surface
-only for cracks upto 3mm in depth
-drying time 6-7 hours)

✓ Eyes
✓ airways

• It’s put increased stress on vital organs such as the heart

*20 % to 40 % increased risk of lung cancer for those come into regular
contact with or work with paint.

OFF GASSING
Give off a chemical, especially a harmful one or in the form of a gas
There is growing concern environmentalists about ‘off gassing’
The process by which chemicals continue to release volatile toxins
into the atmosphere long after their application is complete
 VOLATILE ORGANIC COMPOUNDS

❖ During the life-time of the paint on your

walls, it will also continue to release
chemicals into the environment as
invisible paint pollution.

• There is a contributory factor of the greenhouse effect

and a cause of global warming
• Paints and varnishes are causing as much as five
percent of all VOC emissions

Painting Pigments
Pigments which are used in oil
paints, acrylics etc are
hazardous, especially the dry
pigments because they are
easily inhaled and ingested.
HAZARDS: SOLVENTS
• All solvents cause defatting of skin and
dermatitis from prolonged/repeated exposures
• Turpentine can also cause skin allergies and be
absorbed through skin
• Acute inhalation of high concentrations of
mineral spirits, turpentine vapors, and other
solvents can cause:

PAINT INDUSTRY
The Indian Paint Industry has been growing at a rate of near

About 15% for the past few years.

The industry is estimated at around Rs. 21000 Cr.

The per capita consumption in India is 1.5 kgs p.a., as compared

to the global average of 15 kgs p.a.

HISTORY OF PAINTS
The Indian Paint Industry was initiated in 1902, when

Shalimar Paints set-up its first

factory in Kolkata.
After liberalization, as the excise
duties got drastically reduced

(from 40% to 16%), the industry

recorded a healthy growth of

12- 13% annually.
