Don’t make the mistake of thinking painting rendered walls is as simple as opening a tin of paint, and well, painting.
Each unique surface requires a unique painting process, from preparation to finishing and everything in between. Rendered walls are no exception.
Before we get started, we’d like to point out that painting newly rendered walls is completely different to painting old or damaged rendered walls. So, we’ll look at each scenario separately.
Painting New, Undamaged Rendered Walls
The number one thing to remember when painting newly rendered walls is moisture. Water is added to the render mix to assist with application, and to bind the mortar. If you paint over damp render, water will become trapped. This can lead to a host of future problems, including cracks, mould, and blistered paint. Ensure the render is 100% dry, and then leave it for a few days more. You can never be too sure!
Once your surface is dry, we recommend the following:
- Inspect the walls thoroughly. Look for areas that haven’t been rendered, and check for cracks. If you do find any issues with your render, and you don’t feel confident taking them on, contact your contractor.
- Clean the walls. Often newly rendered walls are dry, dusty or dirty. Don’t use water to clean them. Instead, take a stiff bristled brush or broom and brush over the surface.
- Prime the walls. If your walls are particularly sandy, we suggest priming them.
Now you’re ready to paint! Cut in corners first, then paint the remainder of the walls starting from the top. You may need multiple coats.
Repainting Old, Damaged Rendered Walls
Older rendered walls are more likely to be damaged, which means more prep work is required. Often, this prep work is far beyond the average DIY-er ability – that’s where we (or other tradespeople, if needed) can help.
We will check for the following:
- Flaky paint
- Mould or moss
- Dodgy repairs
- Hollow render
- Old, unused nails or screws
- Damp areas
Once the rendered walls are in like-new condition, painting can begin!
Choosing the right paint and colour for your rendered walls
Your choice of the type of paint and colour will influence not only the aesthetics but also the longevity and quality of the finish. Here’s what you need to know:
Type of paint
Selecting the right combination of the following factors can enhance the beauty of your walls and provide a durable and sustainable solution tailored to your needs and preferences.
Working on exterior rendered walls requires weather-resistant or masonry paint. These paints can withstand harsh weather conditions, protecting your walls from the elements and retaining their vibrancy over time.
Low-VOC or zero-VOC paints have reduced or no volatile organic compounds, making them kinder to the environment and your indoor air quality.
The finish you choose will significantly impact the overall appearance of your walls. Matte finishes offer a soft, non-reflective look that hides imperfections. Satin finishes provide a slight sheen that's easy to clean, ideal for high-traffic areas. Glossy finishes, on the other hand, create a shiny and reflective surface that can make colours pop but might show flaws more readily.
Choosing the right colour
The colour you choose can significantly impact the overall appearance of your property. Selecting the right shade requires careful consideration of your surroundings, personal taste, and how the colour will behave under different lighting conditions.
Complement your surroundings
Think about the colours of nearby buildings, landscapes, and other exterior elements. What fits best with your surroundings?
Remember, lighter colours tend to reflect sunlight, while darker colours may absorb it. What will work best for your space?
