What is Roughcasting?

You may have heard the words roughcast or roughcasting before and perhaps you nod your head approvingly, but really you have no idea what it is. Well, fret no more, because today here at J Gordon Roofing, we’re going to be telling you exactly what it is and what it’s for, so if your home needs roughcasting, you’ll have a heads up on what it’s about.

What is roughcasting used for?

Roughcasting is a finishing methods for the exterior of your home. It consists of gravel and small pebbles which are then mixed into concrete or plaster. It’s then used as a final finish for the exterior surface of a wall. Once dried it usually lasts for many years, so it’s extremely durable and hard-wearing. Roughcasting is popular on commercial buildings, but is sometimes used for out buildings and other common buildings. It’s takes a trained eye to do this because you have to throw the gravel and pebbles directly on to the wall to create a smooth coating with no spaces.

Different finishes and colours

If you travel a lot you may have noticed that in some parts of the world roughcasting is done with tiny sea shells and it’s a great look for a house by the beach. You can also have your roughcasting in different colours too, and this is done by adding colour to the gravel or concrete before applying it on to the surface of the wall. In Tudor times, coloured glass was used, which is such a unique and exciting way to finish off a building. You can also colour over the roughcast after its dried on the surface, such as whitewash or a good quality exterior paint.

Sagging and matching roughcasting repairs

It’s a good idea to not have pebbles or gravel that’s too big, because if they are, they could sag and bring the coating off in parts, leaving it messy and unfinished. It’s usually best to hire a professional who know what they’re doing, as they’ll know the right technique and what materials are required.

Are there negatives to roughcasting?

The only negative aspect of roughcasting is that it can be difficult to repair in terms of matching the colour to the original casting. Sometimes, when roughcasting has become damaged it’s replaced with fresh cast, however it can be easy to detect the new from the old.
