Lining vs. Coating — What's the Difference?
By Maham Liaqat & Fiza Rafique — Updated on April 18, 2024
Lining involves applying a material to the inner surfaces for protection or functionality, while coating refers to covering any surface with a layer to protect or decorate it.

Key Differences
Lining is primarily used to protect the inner surfaces of containers or equipment from corrosion, abrasion, or leakage, whereas coating is applied on both inner and outer surfaces for protection, decoration, or specific functional attributes.
In industrial applications, linings are often thick layers of material such as rubber or ceramic that are bonded to the substrate to provide a barrier against harsh conditions, while coatings can be thin layers like paint or varnish used mainly for aesthetic purposes or light environmental protection.
Linings are crucial for extending the life and functionality of equipment in industries such as chemical processing and wastewater management, on the other hand, coatings are extensively used across various sectors including automotive, construction, and manufacturing for surface enhancement and longevity.
The process of lining typically requires more material and can be more labor-intensive and specialized depending on the application, whereas coating processes are generally less complex and can be applied more quickly and economically.
While both linings and coatings serve to protect materials, the choice between them depends on the specific needs of the application, such as the level of protection required, the type of environment, and budget constraints.

Coating
A coating is a covering that is applied to the surface of an object, usually referred to as the substrate. The purpose of applying the coating may be decorative, functional, or both.Paints and lacquers are coatings that mostly have dual uses of protecting the substrate and being decorative, although some artists paints are only for decoration, and the paint on large industrial pipes is presumably only for the function of preventing corrosion.
