The rough cast is a mixture containing lime, cement, sand, and coarse materials like a pebble. It is also referred to as pebbledash and is mostly applied to the exterior walls. Roughcast rendering is a great way to get some texture to the outer walls. It also offers the walls a layer of protective coating.
Initially, a rough cast was supposed to be a cheaper and convenient alternative to regular rendering. However, over a period of time, it has become popular because of its uniqueness and the way it looks. The process started in the UK and today it is seen across the globe. Wall rendering is usually done post the bricks are laid.
There are various types of rendering options, which include the use of different materials like sand, cement, etc. Roughcast rendering is one of the methods that is cost effective and at the same time gives a great exterior appearance, as well.
Why There is a Need of Rendering
- You cannot have the structure of the house exposed without an outer cover. With the roughcast rendering, there is an outer cover to the walls, which provide an added layer of insulation and protection.
- The rendering is also useful for weatherproofing the house. There can be chemicals and substances added to the mixture to make the exteriors weatherproof, as well. Waterproofing is something that usually goes hand in hand with rendering.
- Rendering also allows you to add a new textural element to the exteriors. Many times, the exteriors of the house can look plain and boring. With such rendering, you get the option of adding some spunk to the exteriors. You can also create a themed design around such rendering.
- This is also a good cost saving option. With regular rendering, you might have to add a coat of the paint once the rendering is done. With the rough cast done, the wall might not need an additional coating of the paint, as the rendering itself provides an attractive option.
Application of Rough Cast

After the wall is prepared, you also have to check the thickness of the paste that is to be applied. If it is, too thin or too thick, you will not be able to get the desired results for sure. Hence, it is important that you have an experienced professional does the job for you. A professional understands the requirements. He will ensure that the mix is prepared in the right way. So, that you do not have to complain about its untidiness or end up being unsatisfied with the quality of the rendering.
