What is the Difference Between Plastering and Rendering?

In the world of construction and renovation, rendering and plastering are two key techniques used to enhance the aesthetic appearance and durability of walls and surfaces. While rendering and plastering are both methods of applying a thin layer to a substrate, they serve different purposes and use different techniques. Here are the main differences between rendering and plastering and the best techniques assisted by rendering contractors in London.

What is Rendering?

Rendering is a construction technique that applies a protective layer to exterior walls, usually composed of cement, sand and water. This mortar is mixed together to create a smooth or textured surface on the exterior walls of the building. Rendering is primarily used on exterior walls, but can also be used on interior walls.

Why is Rendering Important?

According to the rendering contractors near London, rendering protects buildings from weather elements such as rain, wind and UV rays and prevents structural damage and deterioration. A well-applied render can significantly extend the life of exterior walls by preventing moisture ingress, reducing the risk of cracking and improving structural integrity.

Types of Rendering
