Rendering and Plastering: What Is the Difference?

Plastering and rendering both involve applying a coating to a surface, but they are generally used for different purposes.

Plaster is commonly used on interior walls and ceilings to create a smooth surface suitable for decorating. Rendering is generally associated with external walls, where the material needs to withstand outdoor conditions.

The correct material depends on the building, existing surface and intended finish. Preparation is important in both cases because the new material needs a suitable surface to adhere to.

For internal renovation work, plastering may involve skimming existing walls, repairing damaged areas or completely replastering a surface. External work can involve rendering and preparation of exterior walls.

Homeowners in London can speak to London Plastering Service about plastering, skimming, repairs and rendering requirements.

Understanding the difference between the two can help property owners discuss their requirements more clearly when planning building or renovation work.
