Both plastering and rendering refer to a construction process of applying a mortar coating to a wall which hardens as it dries.
So what is the difference between plastering and rendering?
When the mortar mixture is applied to external walls, we call it rendering.
When internal walls are coated, we call it plastering.
Render is mixed with a higher cement content in order to protect the external walls from the elements, whereas plaster is mixed with a smoother, thinner consistency, keeping aesthetics in mind.
When is plastering and rendering used?
The purposes of both plastering and rendering are based on the same principle.
Walls are made smoother, more uniform, and any minor cracks, dents or imperfections can be rectified.
Plastering is an important part of both new home builds and renovations. You may opt to plaster one wall alone, a whole room or even an entire house. Before plastering, rooms need to be clear of furniture and fittings in order for the tradesperson to have the clearest access.
A plastered wall provides a clean, unblemished surface for painting or decorating and creates a blank, uniform canvas throughout a property.
A rendered house exterior provides the same benefit.
Render plays an important job in weather-proofing the external walls, and is a popular choice among new builds and ‘face-lifts’ for older properties. Modern renders are now also available in a range of pre-mixed colours. This removes the need for the added expense of painting the outside of your property when dry. You can also opt for a pebble-dash or brick effect finish.
You may choose to render just the front of your property to create that ‘wow factor’ from the street, or you may wish to have the whole of the exterior rendered to create the ultimate consistent aesthetic.
Rendering can also be used as a finish for brick garden walls.
Plastering and rendering your walls also provides added benefits such as increased insulation and fire resistance. It also adds to the walls structural integrity. Plasterboard may be added before rendering or plastering takes place, or a plaster or render mixed with additional insulating properties may be chosen.
