2. PAINT IS ANY LIQUID OR MASTIC COMPOSITION THAT
AFTER APPLICATION TO A SUBSTRATE IN THIN LAYER ,
CONVERTS TO A SOLID FILM
•IT IS A SIMPLY PIGMENT SUSPENDED WITH A LIQUID
•IT IS USED TO DECORATE, PROTECT AND PROLONG THE
LIFE OF NATURAL AND SYNTHETIC MATERIALS AND
ACTS AS A BARRIER AGAINST ENVIRONMENTAL
CONDITIONS
3. PIGMENT: IT IS USED TO IMPART COLOUR
BINDER: A POLYMER, OFTEN REFERRED TO AS
RESIN, FORMING A MATRIX TO HOLD THE PIGMENT
IN PLACE
EXTENDER: LARGER PIGMENT PARTICLES ADDED TO
IMPROVE ADHESION , STRENGTHEN THE FILM AND
SAVE BINDER
SOLVENT(THINNER): EITHER AN ORGANIC SOLVENT
OR WATER IS USED TO REDUCE THE VISCOSITY OF
THE PAINT FOR BETTER
ADDITIVES: USED TO MODIFY THE PROPERTIES OF
THE LIQUID PAINT OR DRY FILM

20. Paint and natural wood finishes are an effective
way to protect and decorate surfaces.
For a decorative finish coat to last and look as
good as possible, the right base coats are
essential. For interiors, a combined primer-first
coat is a good option.
Interior Painting can be done by brush, rollers,
pads and also through the method of spray gun.
Traditionally, homeowners had a choice between
water-based and oil-based paints, but because
they tend to have higher VOC levels, it's important
to consider if oil-based paints are for you.
21. Most paints fall into one of the general categories
of eggshell, semi-gloss, flat or gloss.
Paints can be categorized in two types i.e. Water
based paint and Oil based paint.
There are different types of interior paints for e.g.
Matt paint,Matt Enamel,SatinEggshell,Semi-
Gloss,Gloss Paint etc.
22. • low VOCs
• easy cleanup with water
• quick drying
• an elastic, flexible finish resistant to cracking
• stable color over time, without yellowing
23. • attractive gloss
• good "leveling" (brush strokes fill themselves in to
create a smooth finish)
• hard, durable finish.
Oil Based Paints are popular for glossy woodwork,
doors, and furniture, as well as demanding
surfaces such as floors.
Be cautious when switching to a water-based paint
if the surface has previously been coated with an
oil-based product, as the new paint may not stick.
In this situation,washing the surface and then
roughening it all over with a medium to smooth
grit sandpaper—making it clean, dry, and dull in
order to prevent peeling of the new coat.
24. When applying over a porus surface,mix wall and
ceiling primer and undercoat with upto 20% water
to make a diluted coat.this will seal the surface and
promote adhesion.
Dilution rate will depend on the porosity of the
surface.A rear patch is required to determine the
correct dilution rate.
Finish with a full coat of wall and ceiling and
undercoat to enhance the top coat colour.
25. Sand down and then clean with a detergent.
Apply one full coat of wall and ceiling primer and
undercoat to promote adhesion and enhance the
top coat colour.
For plaster surface which are porous,chalky or
slightly degraded but otherwise structurally
sound,apply one coat of farrow and ball masonry
and plaster stabilizing primer.
26. Although latex- and oil-based paints can be
applied with rollers or pads as well as brushes,
cleaning them after using oil paints is difficult and
will require lots of white spirit or thinner.
Primer
Use a brush, roller or pad.
First Coat
Use a brush, roller or pad.
Flat
Use a brush, roller, pad or sprayer.
27. When using more than one tin of the same
colour check than the batch numbers are the
same.
Stir paint thoroughly before use.
Apply two coats using a brush or roller. On
application of the final coat lay off the paint in a
single direction.
Estate emulsion modern emulsions, dead flat,
full gloss and estate eggshell as eggshell are dry
in two hours and can be recoated in four hours.
Clean brushes and rollers with warm soapy
water.
