A concrete structure is basically a four-walled structure with a ceiling and a floor. However, it is not the brick and mortar that keeps the entire structure intact. There are different processes that give strength and durability to the structure and provide safety from any sudden fall. Plastering and rendering is one such process that is applied to protect the walls from the exterior and interior factors which could damage the wall. Most of the time, plaster is applied on the interior walls while rendering is done on the exterior area.
According to construction chemicals companies in the UAE, the differences between the two terminologies are not so large. But both the processes involve different techniques and materials which the worker should understand. Both terms have different significant meanings and are not at all interconnected to each other.
Explained below are some of the common differences that one should know regarding plastering and rendering and get enough benefits with the correct usage.
Material Composition: The basic composition for both materials is broadly similar – cement, sand, water and sometimes lime. For plastering, finer sand is used for a smoother finish. While for rendering, a coarser, higher proportion of sand is commonly preferred.
The consistency of the mortar: The mortar’s consistency is one of the important factors which differentiate the render from a plaster. The use of cement is more in the render and less in the plaster. This is specifically because the outer walls have to resist all weather conditions without deteriorating the quality. However, as plaster is used on interior walls, construction chemicals manufacturers say that it is not necessary to make it weather resistant. Therefore, it contains less cement.
Finishes: Modern techniques and skills results in different types of finish are achievable for both plastering and rendering. Rendering commonly offers a coarser finish than plastering. Additionally, pebble dashing is also a type of rendering.
Purpose of using: In particular, rendering is done on the mud blocks because of the constant exposure to water and moisture. Thus, plaster manufacturers in UAE suggest rendering the entire exterior in order to save it from collapsing due to constant moisture exposure. On the other hand, the process of plastering is done to improve the interior looks of a concrete structure. It is basically done to provide a clean and smooth finish which can also be used for decorative purposes.
The above are just a few basic differences between rendering and plastering. There are some parts of a concrete structure that requires extra care. Therefore, while using any process like render or plaster, it is important to know whether it would protect it from getting damaged or not.
