Applying a coat of render to the outside of a property is a fantastic way of giving it a facelift, especially if the existing exterior is in poor condition.

The days of simple sand and cement render are numbered however, since they unfortunately simply don’t stand the test of time. While it looks nice when this type of render is initially applied, very quickly cracks will appear.

The reason is that it has no flexibility

Over the course of the year a property faces a huge variation in temperature – at the peak of summer the external air temperature might be in excess of 30 degrees while during the cold winter months the temperature might drop to below zero. While the house and the mortar (full of lime) can adapt to these changes in temperature, the sand and cement render can’t. What happens is that it will start to crack – leading to a pretty big issue – damp!

A huge amount of water hits a wall during a year and this will travel down to these hairline cracks. The water then gets pulled in through capillary action sometimes right through to the internal wall where damp patches appear. Even so, water travelling behind the render and the external wall will very quickly cause complete failure of the render system.

So you have a property and want to get a new coat of render – what do you do?
