A Complete Guide to Painting Rendered Walls

A Guide to Painting Rendered Walls

Rendering refers to the process of applying a coat of cement on the external walls of a property to make them smooth or textured as desired. The difference between rendering and plastering is that rendering involves the exterior walls while plastering involves the interior ones. Traditionally, rendered walls are built up in two or three coats, which makes it less likely that surface cracks will develop. In this blog post, we’ll share some tips on how to paint rendered walls and the benefits of painting rendered walls. We will also share some news on how we can help you with painting your rendered walls!

Benefits of Painting Rendered Walls

Before we get into the 5 tips on painting your rendered walls, here are a few reasons why you should consider painting them:

Protection from Mother Nature

In its natural form, the exterior rendering does a good job of protecting the walls from the elements. On the downside, it is susceptible to chipping and water damage when heavy rains or strong winds strike. In this case, applying exterior paint works like a top coat that protects the original coating while also adding colour that brightens up your home.

Improved Aesthetics

Repainting your house every couple of years is a good way to make it look fresh and new. In addition, choosing a colour theme for your home that complements the natural environment around it guarantees that you get the most out of this investment. Colours fade and strip off, that’s why having a freshly painted coat on your rendering is important.



Compared to the rest of the house, external rendering has a longer lifespan. This is because it gets coated with an extra layer of cement paste and paints on top. A well-maintained exterior rendering can last for over 25 years before it starts looking shabby and needs replacement. A coat of paint on your rendering can last anywhere between 10-20 years depending on your environmental weather conditions. This long-lasting element makes for a one-time investment to increase your property value and it keeps it looking fab for years to come.

Can Render Be Painted?

Yes, you can paint a rendered wall; however, before you do so, keep the following things in mind: The finish must of the render must cure for 4 to 6 weeks before being painted. If you paint over it too quickly, the moisture in the render will be trapped and cause fractures or cause the paint to bubble. You’ll also need to use exterior wall paint which is much tougher and more resistant compared to other paints. It needs to be able to endure harsh weather conditions, which is why exterior paint is best to use.

How To Paint Rendered Walls

To properly paint rendered walls, you will need to use a primer designed for masonry surfaces. If you feel some sanding will be needed, we recommend you use a quality sandable primer for a flawless finish. You should also use a paintbrush with synthetic bristles, as these are better suited for painting smooth surfaces. Finally, be sure to apply two coats of paint for the best results.

Preparation is the key to obtaining a flawless finish for any paint job, whether it’s on the inside or outside of your home. This is also true for a wall that has been created from render. Let’s start with the most important preparation steps before we get started painting.

Prep work

  1. The first step in preparing for painting any wall is to wash it. Wash the walls and let them dry fully before beginning any project, whether big or small. Clean the surface with a brush, removing any loose render, dust, and debris. If it’s dirty enough to use a hose, allow it to dry completely before starting painting. Apply tarps or sheets to protect the floor from being painted, and mask areas you want to protect from the paint with masking tape.


Painting Your Renders

  1. Start by mixing the paint in the can thoroughly using a flat wooden stirrer.
  2. Pour into your paint tray.
  3. Begin by cutting in – painting the edges first – with a brush.
  4. Once cutting in is finished you can load up your roller with just enough paint to cover it and start on the wall.
  5. Use an M pattern to cover the wall, moving from one side to the other.
  6. Overlap your strokes with the roller so you get even coverage.
  7. Complete the entire wall before taking a break as this ensures a smooth, even finish.
  8. Wait at least two hours before applying a second coat.
