PAINTS
 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
PAINT INGREDIENTS
 PIGMENT:
There are two types of pigment that go into the can on paint:
“Prime” pigments, which provide colour and hide
“Extender” pigment which provides bulk to the product.
Higher quality paints contain more of the all important, yet expensive prime pigments, which in
the end gives you
• Easy Application
• Better colour retention
• Stronger Durability
 BINDERS:
The type, quality and amount of binder affect everything from stain resistant to gloss to
adhesion and crack resistance.
Higher quality binders, found in higher-quality paints, adhere to surface better and provide
enhanced film integrity making it more resistant to cracking, blistering and peeling.
Variety of binders used today.
Latex paint contain either 100% acrylic, styrene acrylic or vinyl binders, while oil
paints typically contain linseed oil, soya oil or modified oils called alkyds.
 LIQUIDS/SOLVENTS:
The liquids provide no added performance benefits. Its simply the “carrier” that
allows to get paint from can to surface.
Higher quality paints have greater ratio of solids (pigments and binder) to liquids,
while cheaper are water downed with liquid.
 ADDITIVES:
These ingredients gives paint a specific benefit that it might not have otherwise have.
Additives such as rheology modifiers ( provides better hide and durability) and
mildewcides (keeps mildew in check) are common additives found in higher ends
paints.
Others include dispersing agents (keeps the pigment evenly distributed) and
preservatives.

INTERIOR PAINTS-INTRODUCTION
 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.
TYPES OF INTERIOR PAINTS
o Most paints fall into one of the general categories of flat, eggshell, satin,
semi-gloss, or gloss.
o Paints can be categorized in two types i.e. Water based paint and Oil
based paint.
o There are different types of interior paints for e.g. Matt paint, Matt
Enamel, Satin Eggshell, Semi-Gloss, Gloss Paint etc.
ADVANTAGES OF WATER-BASED PAINTS
• low VOCs
• easy cleanup with water
• quick drying
• an elastic, flexible finish resistant to cracking
• stable color over time, without yellowing
ADVANTAGES OF OIL-BASED PAINTS
• 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.
FOR PLASTERING SKIM PLASTER,LINED
WALLS
 When applying over a porous 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 color.
FOR GLOSSY OR OIL BASED SURFACE
 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.
APPLICATION METHODS OF PAINTS
 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.
 When using more than one tin of the same colour check if 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.
