An Essential Guide to Type of Paints
Paint is a form of liquid which, on drying, forms a thin film on the painted surface. Type of paints vary based on solvents, application, sheen, etc.
Paint is a form of liquid which, on drying, forms a thin film on the painted surface. It can be applied on timber, brick or on any other materials.
The main function of paint is to provide protection or decoration or both.
It prevents wooden structures against warping, checking, or decay.
Metals corrode if not painted at suitable intervals
Painting enables the masonry and concrete work to resist checking and disintegration, thereby extending life.
Paint is composed of two main components -pigment and organic binder.
PIGMENT – Solid ingredient of paint and is used in the form of fine powder.
ORGANIC BINDER – Liquid part of paint and it is called vehicle.
Type of Paints Based on Solvent
- WATER-BASED PAINTS
- OIL-BASED PAINTS
The solvent or binder used in water-based paints is almost water
Low VOC’s emission
Flexible and less susceptible to cracking
More resistant to UV rays
Can tolerate small amounts of moisture prior to application as it absorbs moisture
Takes less time to dry
Does not require a pre-treatment
Stable color over time, doesn’t become yellow
Lower sheen finish when compared to oil-based paints
Less tolerable to different variations in weather conditions.
Oil based paints use an organic solvent typically a mineral turpentine
Good for high moisture rooms
High durability and rich finish/sheen
Excellent resistance to wear and tear
More tolerant to differing weather conditions
Brushstrokes fill themselves-no strokes seen appearing smooth finish
Less flexible, likely to crack, become dry and brittle over time
High toxic emissions (VOC’s)may lead to health issues
If moisture is present on the surface, oil paints repel and does not create a strong bond.so the surface has to be completely dried.
Take longer periods to dry
Turns yellow over time
Used for woodwork and metal surfaces.
Made by mixture of aluminum powder and quick drying spirit varnish/slow drying oil varnish to suit requirements of surface.
Weather resisting and waterproofing qualities.
Resistant to corrosive action of seawater.
Mostly used for painting interior or exterior metallic surface, commonly applied on radiators
High reflective property.
Used as a metal protection paint for preserving structural steelwork
Prevents from effect of acids, fumes, corrosive chemicals
Resistant to rough weather conditions.
Cement Based Paints
Type of water paint in which white or colored pigment and cement forms the base
Applied to exposed or plastered brick masonry and concrete work.
Especially suitable for patchwork or stopping leakage in metal roofs.
Used for painting gutters, flashings, etc. To prevent from rusting.
Used for painting exterior brickwork and plastered surfaces
Alkali resistant and provide protection of iron and steel.
Made by adding pigments like white lead or zinc white to a binder which is varnish
Stand well with the adverse effects of atmosphere
Commonly used for painting porches, decks, stairs, concrete surfaces.
Rubber Base Paints
The paint is made from rubber treated with chlorine gas which is dissolved in suitable solvents and mixed with other pigments
Excellent acid, alkali and moisture resistant properties.
Commonly used as protective coating on cement concrete floors, interior or exterior masonry surfaces.
Paint is made from celluloid sheets and amyl-acetate substitutes.
Stands well with rough weather conditions
Hard, flexible and smooth
Due to its high costs, restricted to motor cars/vehicles
Casein is a protein substance extracted from milk curd which is mixed with a base consisting of white pigment
Usually applied on walls, ceiling, wallboards, cement blocks to enhance the appearance of the surface.
Type of Paints based on Finish/Sheen
Low gloss and non-reflective finish (low gloss paint sheens absorb light)
Mostly used for interior walls and ceilings of living, bedroom, dining, etc.
Perfect for low traffic areas
Hides imperfections like chips or cracks in walls
Hard to clean handprints and other marks
Requires less no. of coats than glossy finishes.
Low sheen, soft and velvety smooth like an eggshell
A kind of sheen between satin/glossy and gives a beautiful classic look
Perfect for low to mid traffic areas
Have little reflectivity.
Provides pearl-like smooth and velvety finish
Easy to clean than low gloss finishes and resists chipping and peeling off
Works well in high traffic indoor areas
Reflect a bit of light
Shiny than satin finish, smooth and sleek
Less reflective than glossy finish and more reflective than matt and eggshell finishes
High resistant to moisture, suitable for high traffic areas
Bathrooms, kitchen cabinets, doors and windows etc.
Highlight imperfections on walls
High reflective and glass-like finish (high gloss paints reflect light)
Suitable for high traffic areas
Highlight imperfections on walls clearly
Common for furniture, cabinets, decorative trims, etc.
Type of Paints Application Method
Most common paint application methods are
PAINTING WITH BRUSHES
