External Render – Anti-Crack Systems
From historic and protected buildings to the most avant-garde architecture, some of the most exciting developments in building technology in recent years have been the improvement in anti-crack renders.
At Gaffney and Guinan, one of the products we offer is an external render. Simply put, this means putting a coating on the outside of a building to protect it from rain and insulate, while also providing a decorative finish.

Types of External Render
There are various types of external render which you can have installed. Which one you decide to go with may be a result of your aesthetic preferences
- Cement Renders – Cement render is the standard render used for external rendering. It is mixed on-site and then applied in coats. The last coat is applied thinner and giving a good finish to ensure it’s ready for painting.
- Polymer Renders – The material for polymer renders comes pre-mixed, based on either lime or white cement. Plastic products are then added into the mix in order to make the render tougher and crack-resistant.
- Acrylic Renders – Acrylic Renders are normally done to create a good finish for your home. They are applied as a thin finish to seal the underlying coat and enhance its appearance.
- Monocouche Renders – Monocouche is a French word meaning “single-layer’ or ‘bed’. Monocouche renders are a new development in the rendering industry. It comes ready to mix with water. It is a single coat render which can be applied by hand or by machine. White cement is used, but it is normally coloured ahead of time in various shades. As it is only one coat, it is quicker than most types.
- Lime Renders – Lime plastering used to be more popular years ago, but there has been a re-emergence of interest in lime renders in recent times. It’s more difficult to install than standard rendering, meaning it’s usually designated for complete renovation projects, many companies now offer lime renders.
- Insulating Renders – An insulating render can be used to refurbish a home. It is useful when external walls are poorly insulated or are deteriorating. Additionally, if the external walls are currently causing water damage or leaking, an external render can help.
If internal insulation is too intrusive and difficult to install, external rendering is the perfect solution.
Insulated rendering includes rigid insulation which is attached to the wall, a reinforcing mesh, a base coat of the render, and a finishing coat of render.
Every building has a unique place in its environment. Our anti-crack renders are designed not just to protect and improve each building, but to enhance what is most special about its character.
