PAINT
Can be used for material made of wood,
steel, concrete and bricks.
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 paint companies are :
ASIAN PAINT , NEROLAC , BERGER ,ICI
Distemper
This is perhaps the most economical type
of painting available in the Indian market
today. It can be classified as a
"Whitewash" job. The major constituents
of distemper are chalk, lime, water and
some coloring agents if necessary.
Distemper is a water based paint.
http://www.frontdesk.co.in/forum/
Emulsions
An emulsion is a liquid having fine suspended
particles. It is commonly known as plastic paint.
This is water based and provides a rich and Matt
finish to interior walls. The differentiating factor of
emulsion paints is its acrylic quality. Its composition
imparts excellent durability to the painted surface
and gives the walls a just painted look. It washable
and most stains can be removed easily by wiping
with a cloth dipped in a mild soap solution. The
paint film is also fungus and mildew resistant.
Covering capacity on new surface per coat is
Exterior 5.5 to 6 m2 / litre
Interior 17 m2 / litre

ENAMEL PAINT
Enamel paint is paint that air dries to a
hard, usually glossy, finish, used for
coating surfaces that are outdoors or
otherwise subject to hard wear or
variations in temperature
Typically the term "enamel paint" is used
to describe oil-based covering products,
usually with a significant amount of gloss
in them, however recently many latex or
water-based paints have adopted the term
as well. The term today means "hard
surfaced paint" and usually is in reference
to paint brands of higher quality, floor
coatings of a high gloss finish, or
spray paints
http://www.frontdesk.co.in/forum/
Solvent based paints
(Lustre/Enamel)
Solvent based paints - Lustre paints,
Enamel paints and oil paints all come
under the category of solvent based
paints. They cannot be pre-mixed with
water. Oil based paints take a longer time
to dry and often produce strong odors
which are irritating and sometimes even
toxic in nature. The advantage with these
paints is that they really last long and
produce rich and desiring effects on the
wall.

Three Types of Wood Finishes
Transparent Coatings- coatings that can be seen
through.
Ex. Varnish, Shellac, lacquer , PU , Melamine
Penetrating Finishes- these soak into the wood rather
than just coat it. Ex. Linseed Oil, Danish Oil
Opaque Finishes- covers the surface completely, cannot
be seen through. Ex. Paint, enamel
http://www.frontdesk.co.in/forum/
Transparent Coatings
Varnish- a preparation consisting of various resins
and drying oil (linseed oil, tung oil, and walnut oil.) dissolved
in an Turpentine ,oil , water or in alcohol. When applied to
the surface of wood, it dries and leaves a hard, glossy
transparent coating.
Shellac- a varnish made by
dissolving this material in alcohol or a
similar solvent.
Lacquer- a protective coating consisting of a resin,
sometimes with pigment added.
Resin – Resin is a thick and sticky yellowish- brown
substance used to chemically bond materials together. Resins that
are used in varnishes include amber, kauri gum, dammar, copal,
rosin (pine resin), sandarac, balsam, elemi, and others

varnishes and in linoleum, printing inks, and synthetic
resins.
Danish Oil- is a blend of oils and resins that
penetrates, seals, and preserves wood surfaces.
http://www.frontdesk.co.in/forum/
Brushes used for Finishing
Two main brushes used are bristle brushes and
foam polybrushes.
Natural bristle brushes- are made with hog hair, commonly
used with oil base paints.
Synthetic bristle brushes- are made of nylon or polyester,
commonly used with water soluble finishes, and most oil base finishes.
Foam polybrushes- made of plastic foam tapered on both sides
to a sharp point, can be used on most finishes.

Applying Wood finish :
The steps required to create a durable wood finish are called a
“finish system,” is comprise the following:
2) Staining
3) Grain filling
4) Glazing
5) Top coating:
i) Filling nail holes
ii) Final top coating
6) Maintenance
1) Preparatory steps:
i) Stripping away of old finish
ii) Bleaching
iii) Patching (if necessary)
iv) Sanding
v) Priming or sealing
http://www.frontdesk.co.in/forum/
Stripping away of old finish:
1. Mechanical stripping:
This involves using sharp blades or scrapers to physically lift the
old finish from the wood surface. Depending on the material, the
application of a stream of hot air from a heat gun as the surface is
scraped may facilitate the removal of the existing finish.
The other mechanical method for removing an existing finish is to
use abrasive materials commonly referred to a “sand paper.”
2. Chemical stripping:
There are many chemical compounds sold as paint strippers or
finish removers. Most of these contain Methylene Chloride or N-Methyl-
2-Pyrolidone (“NMP”) as an active ingredient. These
compounds are generously applied, usually by brush, over the
existing finish and the adhesion between the wood and the finish
will be broken. If the existing finish consists of several coats,
multiple applications may be required.

http://www.frontdesk.co.in/forum/
Sanding
Sanding is crucial to preparing your wood for
a finish, whether it be hand or power sanding.
Anyone tell me why?
Different grit sand paper
Coarse- (80 grit)
Medium to fine- (100-180 grit)
Very Fine- (220-280 grit)
Applying Stains and Clear Finishes
Staining- is the process to change the color of the wood
without changing it’s texture.
Types of stains:
Pigment stains -are made by adding color pigments
together.
Penetrating stains – are made by mixing aniline dyes in
oil.
http://www.frontdesk.co.in/forum/
Applying Stains Cont…
Wood Stain Finishes:
Wood Toned - Lightly pigmented wood-toned
finishes add color to the wood, while
enhancing its natural beauty.
Semi-Transparent- Semi-transparent
finishes allow both the natural grain and
texture to show through.
Solid Color- The most durable finish, solid
color stains reveal the texture of the wood,
but generally conceal the grain.
http://www.frontdesk.co.in/forum/
Clear Finishes
Two basic types of clear top-coat finishes:
Those that penetrate the wood
Ex- linseed oil, danish oil
Those that stay on top of the surface
Ex. Shellac, varnish, polyurethane and lacquer
http://www.frontdesk.co.in/forum/
Applying Sealer
After stain has dried completely, a sealer
should be applied over the stain before a
clear finish is applied. Why?

http://www.frontdesk.co.in/forum/
Applying a filler
This is put on over the sealer to seal the pores
of the wood before applying a clear finish.
Apply filler first along the grain of the wood. Then work
across the grain to fill the pores completely.
http://www.frontdesk.co.in/forum/
Applying VARNISH
A paint coating that lacks pigment & which gives
a transparent / translucent finish to wood.
paint that provides a hard glossy transparent
coating
It greatly enhances natural beauty& figure of
wood.
Method polishing the wood with varnish is
French Polishing.
Ensure the surface are clean (no dust) and
smooth before applying varnish.
http://www.frontdesk.co.in/forum/
Applying Paint and Enamel
These may include, water based latex or oil
based.
An enamel paint is a paint that dries to an
especially hard, usually glossy, finish.
Before applying paints, a primer should be
applied, priming ensures better adhesion of
paint to the surface, increases paint durability,
and provides additional protection for the
material being painted.
http://www.frontdesk.co.in/forum/
Applying an Oil-Based
Polyurethane:
One can apply an oil-based polyurethane using a fine-bristled brush, a
clean cloth or a foam brush. Avoid using inexpensive bristle brushes, as
these will tend to leave obvious brush strokes. Brush with the grain of the
wood, using a sufficient, but not overly thick coat of polyurethane. Avoid
overbrushing, but be sure use long strokes to brush out as many bubbles
as possible. The few remaining bubbles will typically disappear within
moments.
After the first coat has dried ( wait 24 hours), lightly sand the entire
surface (again, with the grain) with grit sandpaper. The polyurethane will
sand easily, so be careful not to sand through the thin coat and damage
the stain underneath. Wipe off all dust caused by the sanding before
applying a second coat.
Repeat these steps until the desired level of protection is achieved (two to
three coats is usually enough). After your final coat, you may choose to
rub out the finish with steel wool to a consistent sheen level, followed by
an application of paste wax for a nice luster.
http://www.frontdesk.co.in/forum/
Applying a Water-Based
Polyurethane:
Water-based polyurethanes don't match well with oil-based stains,
so if you're applying over stain, you'll want to "rough up" the stained
surface slightly before applying your water-based polyurethane
using some synthetic steel wool. Since oil and water don't mix, this
will help the polyurethane to avoid beading on the surface like
water on a freshly-waxed car.
Apply a very thin coat of polyurethane with a fine brush, foam pad
or cloth. Work with the grain, and avoid applying too much
polyurethane to avoid raising the grain.
The initial coat should be dry within a couple of hours, and a
second coat can be applied. If applying in this manner, one
shouldn't need to sand between coats as with the oil-based version.
However, in order to get the same amount of protection, you may
need to add a dozen or more coats of the water-based
polyurethane.
