TYPES OF PAINTS
Oil paints use white lead as a base, and are applied in three coats: primer, undercoat and finish coat. Oil paints can achieve mat and glossy finishes, while being durable and affordable. They are characterized by their ease of application, and painted surfaces are easy to clean. Oil paint is commonly used in walls, doors, windows and metal structures.
Note that oil paint is not suitable for humid conditions, and it takes time to dry completely. Also, before applying oil paints, linseed oil and pigments must be added.
This type of paint is produced by adding lead or zinc to varnish. Pigments are added to achieve a wide variety of colors. Enamel paints form hard and glossy coatings, which are easily cleaned. They are characterized by being waterproof and chemically resistant, offering good coverage and color retention.
The following are some common uses of enamel paint:
The main limitations of enamel paint are slow drying, and requiring a titanium coating before application.
- Interior and exterior walls
- Wood trims, doors, and flooring
- Surfaces like wicker, masonry, concrete, plaster, glass, and metals.
Emulsion paints use polyvinyl acetate and polystyrene as binding materials, and they contain driers like cobalt and manganese. They can be water or oil based, and pigments are used to achieve the desired color. Emulsion paints are characterized by their fast drying and hardening, and surfaces can be cleaned easily with water. Once applied, enamel paints offer durability, good color retention, and alkali resistance.
Emulsion paints are commonly used for interior walls, ceilings and masonry work. Some specialized types of emulsion paints can be used for woodwork.
Cement paint is available in powder form, which is mixed with water to achieve paint consistency. The base material is white or colored cement, and it may also contain pigments, accelerators and other additives. Cement paint is durable and waterproof, and it is commonly used in rough internal and external surfaces.
Consider that cement paint has a long drying time, typically 24 hours. It must also be applied in two coats to prevent dampness issues.
This type of paint is made from dissolved asphalt or tar, which gives it a characteristic black color. It is waterproof and alkali-resistant, but not suitable for applications where it will be exposed to the sun, since it deteriorates.
Bituminous paint is commonly used in underwater ironworks, concrete foundations, wooden surfaces and iron pipes. It also helps provide rust resistance when applied in metals.
This type of paint is produced by mixing aluminum particles with oil varnish. It is resistant to corrosion, electricity and weather exposure. Aluminum paint is commonly used for metals and wood, and some specific applications are gas tanks, oil tanks, water pipes and radiators.
The very finely ground aluminium is suspended in either quick-drying spirit varnish or slow-drying oil varnish as per requirement. The spirit or oil evaporates and a thin. The advantages of aluminium paint are as follows:
The aluminium paint is widely used for painting gas tanks, hot water pipes, marine piers, oil storage tanks, radiators, etc.
- It is visible in darkness.
- It resists heat to a certain degree.
- The surfaces of iron and steel are better protected from corrosion by this paint than any other paint.
- Metallic film of aluminium is formed on the surface. (iv) It possesses a high covering capacity. A litre of paint can cover an area of about 200 m2.
- It gives good appearance to the surface.
- It is impervious to the moisture.
- It possesses high electrical resistance.
This paint essentially consists of oil and a strong drier. A pigment such as chromium oxide or lead or red lead or zinc chrome is taken and after mixing it with some quantity of very fine sand, it is added to the paint.
The advantages of an anticorrosive paint are as follows:
- It is cheap.
- It lasts for a long duration.
- The appearance of the paint is black.
Synthetic Rubber Paint
This paint is made from dissolved synthetic resins, and can include pigments. It has a moderate cost and its main benefits are chemical resistance, fast drying and weather resistance. Synthetic rubber paint is used for concrete surfaces in general, and this includes fresh concrete.
It has the following advantages:
- It offers good resistance to the water and is not affected by heavy rains.
- It dries quickly.
- A uniform colour is maintained when this paint is applied on the surface.
- It is little affected by weather and sunlight.
- It can be applied on surfaces which may not be completely dry e.g. fresh concrete.
- It is moderate in cost and covers a sizeable area.
- It is easy to apply on the surface.
- It possesses excellent chemical resisting property.
Cellulose paint is produced from celluloid sheets, amyl acetate and photographic films. Adhesion can be improved by adding castor oil, and surfaces can be easily cleaned and washed once the paint has dried. This type of paint is characterized by its quick drying, smooth finish and hardness, while offering resistance to water, smoke and acids. Thanks to its properties, cellulose paint is commonly used in cars and airplanes.
The main disadvantage of cellulose paint is its high price.
This paint uses water as a thinner, and it is available in a wide range of colors. It dries very quickly and offers high coverage. The following are some common applications:
- Walls and ceilings of auditoriums, showrooms, display rooms, etc
Silicate paint is made from a mixture of silica and resinous substances. Its performance benefits include good adhesion, hardness, heat resistance, and being chemically unreactive with metals. Therefore, this type of paint is commonly used in metal structures.
This paint is made from casein mixed with white pigments. It is available in powder and paste form, and pigments can be added. Casein paint is commonly used to paint walls, ceilings and wood.
Why BPT for Painting?
Rusting Process Slows Down
Slower rusting and degradation to building structure
Saves costs and better building life thus reduced maintainance.
All Weather Protection
Weather hot or cold, always shines and does its job.
