The coating of oil paint consists of a drying oil like poppy or linseed oil; which dries through oxidation and not evaporation.
Oil paint or oil-based paint is also called “alkyd.” It used to be the most popular paint in history. It is made from mineral spirits and petrochemical solvents.
Oil paint is mostly used to paint furniture, cabinets, and molding. Its composition makes it suitable to provide a protective coating and a smooth finish. When completely dry, it mimics a hard shell like characteristics.
1. It gives a smoother finish, almost "glass like"
2. A high viscosity makes it cover more surface thoroughly in a single coat
3. It provides a hard and durable "shell like" finish
4. May shrink less than other types of paint and pulls tight

Disposal of oil paint is regulated by the local waste management agencies. It must not be poured down a drain or cast out in the environment. Always be responsible when disposing paint and tools associated with oil based paint.
Latex paint is also called “acrylic” paint. It consists of a plastic resin made of polyvinyls or acrylics allowing it adhere better to the painted surface. The catalyst of latex paint is water with glycol ethers or glycols as a solvent.
Pros of Latex Paint
