Cave of a 100,000-year-old human-made ochre-based
mixture that could have been used like paint.
Cave painting drawn with red or yellow
ochre, hematite, manganese oxide, and charcoal.
As long ago as 38,000 B.C., people used paint made from
soot, earth, and animal fat to adorn the walls of their

CLASSIFICATION OF
ON THE BASIS OF BASE USED
 Oil Paints utilize a drying oil that oxidizes and
hardens to form a tough elastic film when
exposed to thin layer of air.
 Alkyd Paints have as a binder an alkyd resin, such
as chemically modified soy or linseed oil.
 •Latex Paints have as a binder an acrylic resin that
coalesces as water evaporates from the emulsion.
 •Epoxy Paints have an epoxy resin as a binder for
increased resistance to corrosion, abrasion and
chemicals

ON THE BASIS OF PROPERTIES
 Rust Inhibiting Paints & Primers:These are especially formulated
with anticorrosive pigments to prevent or reduce the corrosion of
metal surfaces.
 Fire Retardant Paints: These are especially formulated with silicone
and polyvinyl chloride or other substance to reduce the flame spread of a
combustible material
 Heat Resistant Paints: These are specially formulated with
silicone resins to withstand high temperatures.
 Intumescent Coatings: These when exposed to the heat of a
fire, swell to form a thick insulating layer of inert foam that
retards flame spread and combustion.

Distempers
Distempers are durable and economical water based
paints .
Its constituents :Colouring agents, as well as chalk
and lime.
They have been the main painting substance for
decades and still are excellent budget painting
solutions. Even the distempers now used are more
varied and have special properties.

• These are the superior quality of paint formed by
mixing oil/water
• Emulsifying agent to prevent the combination
separating
• They have much better ease of application, are
washable and have a greater overall decorative
appeal. Not only do they have higher coverage than
enamels and distempers, they are mostly washable
and can be
• Easily applied on concrete and stucco surfaces. As
per the interior and exterior painting requirements both
interior and exterior emulsion paints exist.
Emulsion Paint

13. 13
• Enamels are hard, washable and usually glossy
paints.
• Either can be oil based or alkyd based
• Application not only on metal surfaces but also on
interior walls and wooden surfaces
Enamel Paints

• Used to create to desired visual effects on the
walls.
• By the use of brushes, rollers, putty knives,
trowels and other applications a variety of
patterns can be created.
• Other paints can be applied on the textures to
create desired effects. Sometimes, texture paints
are tinted prior to application, giving the desired
colour.
• Texture paints also help in covering undulations
and levelling surfaces.

• To give a new look for concrete and other cementbased
materials, cement paint is the perfect answer.
• It is a special paint coatings made for masonry and
cement-based materials, including concrete, mortar (and
brick), concrete block.
• Not only it adds to the aesthetics of the wall but also
provides a waterproofing coating and can supplement the
role of putty.

These are basecoats applied to a surface to improve the
adhesion of subsequent coats of paint or varnish.

PROCESS OF PAINTING
Surface Preparation
• Surface preparation is important because it directly
affects the surface finish of the paint.
• A paint scrapper, 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. All loose
material is removed and filled with plaster or putty
mixture.

18. 18
• It is essential, especially when the walls to be painted are
stained, porous, have water damage or when we are
painting a light colour over a dark color or vice versa.
• Primers help provide smooth surface, making the surface
less absorbent.
• Increases the spreading capacity of the paint. Using primer
on the kitchen, bathroom and exterior walls is especially
important to aid in the prevention of mildew.
• provide better adhesion to the top coats.
• The type of primer used is also dependent on the kind
of surface to be painted, i.e. different primers exist for
interior walls, exterior walls, wood, metals etc.
Primer coating

19. 19
Putty Coat
• Applied to walls after first primer coat has dried
• It will fill in minor cracks and surface imperfections, and
provide a protective sub-layer for the expensive paint
• As per the requirement 1-2 coats of putty can be
applied, but it is required to allow the previous coat to
dry before applying subsequent coat

20. 20
Finish Coat
For fresh surfaces or the surfaces that need considerable
leveling and removal of undulations, two primer coats are
required.
Second Primer Coat
Generally two coats of finish coat are required to get
the desired finish and color. It is important that each
coat must be completely dry before the application of
next one.

Lead released into the environment makes its way into
the air, soil, and water.
Man and animals are directly exposed to lead through
ingestion and inhalation.
In paints and primers, lead is primarily used as
pigment.
Lead is also added to paint to speed drying, increase
durability, retain a fresh appearance, and resist
moisture that causes corrosion
