Other than modern methods of rendering, other more traditional methods are still available and widely used.
Sand and Cement rendering is the application of a premixed layer of sand and cement to a wide range of masonry substrates. It is often painted after application. It is generally used on exterior walls but can be used if necessary on interior walls.
Rendering in sand and cement provides a very durable covering to walls. It is the cheapest method available.
Although it has high durability, it is not a flexible system and so is more prone to cracking than other systems.
