Paint is a liquid used to add color to surfaces by covering them with a pigmented coating. There are several types of paint including enamel paint, emulsion paint, and distemper paint. Enamel paint contains white lead, oil, and resinous materials and can be used for both interior and exterior walls. Emulsion paint dries quickly, is easy to apply, and durable. Distemper paint is the most economical but only for interior walls. Before painting, surfaces must be prepared by allowing moisture to escape, applying primer coats, cleaning, and removing defects. The painting procedure involves applying paint in 3-4 coats, with the first as a primer, second as an undercoat, and remaining coats as

5.  Emulsion paint
 Contains binding materials such as
polyvinyl acetate, synthetic resins
 Dries in 1.5 – 2 hours
 Easy to apply
 More durable
 Can be cleaned with water
 Possess good weather and alkali
resistance.
 Emulsion paint needs sound
surfaces(first coat of cement paint is
applied)

7. Preparation of surface before
painting
 It is necessary to allow moisture
content to escape from newly
constructed wall. It usually requires 3-
6 months for the surface to be ready
for painting
 Coats of alkali resistant primer paints
or non oil based paints should be7

8.  Defects in the cement plastered surface
should be removed
 Surface should be cleaned
 Spots showing efflorescence should be
brushed off
 If there are chances of discolouration
due to microorganisms, surface should
be cleaned and sterilised with antiseptic
wash

9. Painting procedure
 Paint applied in 3-4 coats
 First coat known as priming coat
Creates a layer or film providing
adhesion of the paint with the surface
 Second coat: undercoat
Serves to provide foundation or
support to the finishing coat, surface
made even and irregularities removed
