Exterior rendering is the process of applying an external wall covering to the exterior of a house in order to provide added protection to the bricks it's built from.
The external wall covering protects bricks from the effects of weathering and erosion which can, over time, cause both cosmetic and structural damage.
However, the covering alone is not sufficient as this too is susceptible to damage over time from weather and other environmental factors. Therefore, once the wall covering has been applied, it's usually then painted or a wall coating in order to stop it from cracking and prevent damp from seeping through it and into the home. It also requires regular maintenance and re-painting in order to repair any damage that may occur to the paint or wall coatings.
The whole process of exterior rendering is usually carried out by coating specialists like Apex Coating Services
