Rough-cast is a type of cement render that can be applied to external walls of properties. In its heyday, it was a popular choice in the UK but now, there are modern alternatives that can provide better protection, functionality and aesthetics. Here, learn all about rough-cast and if you already have it on your property, find out how to maintain it.
Rough-cast has long been a popular option in places such as Scotland where weather can be harsh and properties need additional protection. It uses jagged-edged stones to create its distinctive appearance, which has both functional and aesthetic benefits. Functionally, it provides an extra layer of protection to brickwork. Aesthetically, the outer layer effectively shields the brickwork and can create a finish that is more aesthetically pleasing. However, this has also allowed builders to use lower-cost bricks, benefiting them but not necessarily benefiting the property. Rough-cast might be disguising some issues that are only discovered upon further investigation.
While rough-cast can be a durable option, it presents problems over time. After years of exposure, rough-cast render might develop cracks, bossing and moisture stains from rainwater exposure. It can also become stained by carbon deposits from the air. At this stage, rough-cast will need to be maintained or replaced in order to protect the property.
