Faulty render can be the start of a nightmare with problems around your home.
How to identify faulty render
Firstly, render can be a number of different things; it can be pebbledash, roughcast or the smooth variety. But all renders do the same thing – they offer a protective outer layer to the building. Faulty render can cause you some issues.
Render does require some maintenance to stop some serious flaws developing.
- Cracking or bulging render is not good
- Blown render will sound hollow when tapped
- Chunks of render can fall off if not applied or treated properly
What causes faulty render?
Sometimes the faulty render issues are caused by structural movements. Render can develop hairline cracks over time. If the wall behind the render moves or cracks then the exterior render will do the same.
How to repair faulty render
Render was traditionally applied in 3 layers;
- Set coats
Now it is more common to see 2 coats of render. The strength of each coat is important and will vary depending upon the type of brick that it is applied to.
You can do a repair on your faulty render. You will first need to hack off the loose or cracked render so you expose the wall. Then the wall must be allowed to dry out before you do any patching. Whether you are getting a professional in, or are thinking of repairing your own faulty render it is worth noting that an invisible patch job will be impossible to achieve with standard render.
