FAQs
Can a render be applied over house paint?
In most cases applying a render over house paint is discouraged. This is because it is almost always difficult for any render material to adhere properly to a painted surface. If you want to render a home that is currently painted the best approach is to remove the paint, or to apply a bonding agent over the paint to help ensure proper adhesion. That said, removing the paint entirely is the preferred approach.
Can a new residential render be applied over an old render?
We would not recommend trying to apply a new render over an existing render, simply because you will likely have problems getting the new render to stick to the surface of the old render. It is recommended that you remove the old render first. Be advised this is a labour-intensive project and should be left to experienced professionals who have the tools and experience to do the job right and in a timely fashion.
Is house rendering considered a good investment?
Yes, it is. A render can significantly enhance the comfort, liveability and energy efficiency of your home. Rendering will also protect your home from water damage and enhance your home’s curb appeal. All these things taken together should result in a nice bump in your home’s market value.
What is the most affordable type of exterior wall coatings?
The cement render is the most affordable type of render. This has made it the go-to choice for homeowners on a budget for many years. A cement render creates an effective barrier against moisture, is reasonably durable and able to stand up to whatever Mother Nature throws at it. On the downside it is more likely to crack than other materials like silicone because it is not flexible and the curing time on a cement render can be considerable, sometimes stretching into weeks.
Do rendered walls require maintenance?
In general, all that’s needed is for the rendered surface to be cleaned once a year to remove dirt and any mould that may have taken hold. If you have a cement render you should look for cracks while cleaning it and repair them immediately.
