What's the distinction between plastering and rendering?

 

The distinction between render and plaster, as well as when each should be applied, is frequently misunderstood. Knowing the difference between these two items will help you discover a qualified renderer or plasterer whether you're building a new house or renovating.

What are the similarities and differences between rendering and plastering?

Cement render and plaster are both types of mortar coatings that are applied to blockwork to provide a smoother, more equal surface. While the applications of cement render and plaster differ, they are both made from the same ingredients, which are a mixture of cement, sand, water, and sometimes lime.

Plastering vs. Rendering.

The amount and consistency of the materials in the combinations varied between various items. Render contains more cement than plaster and is thus thicker, as it must be weather resistant because it is used on the outside of structures. Plaster, on the other hand, needs less cement because it is used on internal walls and is not subjected to the impacts of wind, rain, and sun, thus it does not need to be as strong. Plaster is often created from finer sand, whereas render is made from coarser sand. This is because plastering is done before painting to give a flat surface for an even paint finish.

Premixed renders frequently include polymers and other special rendering chemicals to strengthen their durability and resistance to water, reducing cracking and chipping on impact.

 

When should you use render?

As previously stated, the variation in consistency between render and plaster is related to the varied strength requirements for their respective applications. For a variety of reasons, cement rendering, acrylic rendering, and polymer rendering are utilised on exterior walls:

·        To improve the look and texture of external surfaces

·        To alter the colour of exterior walls or surfaces

·        To fix external wall cracks

·        To raise a property's worth

·        To add an insulating layer to the walls

·        A building's waterproofing and fireproofing

·        To cut down on long-term maintenance expenditures

The greater strength of the render due to the higher amount of cement rendering and coarser sand is advantageous for these purposes of repairing and maintaining external walls for many years. When subjected to extreme conditions, blockwork is prone to cracking or disintegrating, becoming soft under pressure. A rendering specialist will know how to apply to render in the most efficient method to preserve your home or project in the finest possible condition.

 

Outside wall rendering is done by laying the render in sheets, applying it with a trowel, and finishing it with a variety of tools, depending on the desired finish. Many individuals like a smooth, flat finish, but others prefer a textured, patterned finish. This is a matter of personal preference and the requirement for the render to complement the rest of the property.

When should you use plaster?

Plaster, on the other hand, is exclusively used on internal walls and ceilings to get the smoothest surface possible. This is because smooth walls are much easier to maintain and decorate with paint or wallpaper. This clean finish is ideal for improving the aesthetic appearance of a building's interior walls.
