Painting a house with rendered exterior walls might sound difficult, but it doesn’t have to be. There is more to it than simply opening a tin and starting to paint, but with the right preparation it can be easily achieved. Professional decorators such as Scott Anson Painters and Decorators Ltd. can help to make light work of the task.

Preparing the Wall

Preparation is a crucial step of any painting process, and this is especially important when it comes to painting a rendered wall. If the render is fresh, it will need adequate time to dry fully before it can be painted, otherwise the paint could crack or bubble. If the render is older, it will need to be thoroughly cleaned beforehand to remove any moss, dirt and old paint. It is also necessary to make sure any holes or missing areas of plaster are repaired before painting begins.

Before painting a masonry wall, the render needs coating with a stabilising solution. Skipping this step can lead to paint flaking off the wall. Mix the stabilising solution thoroughly and then apply using a brush. Render walls act like a sponge and soak up the solution, so be sure to buy enough. The stabilising solution will need to dry thoroughly before the wall can be painted.

Painting the Wall

Before getting started, make sure to mask around areas that need protecting from paint, and spread protective sheeting across the ground and over any plants. Once ready to paint the rendered surface, start by cutting in around the edges of the area with a brush.

Once the edges have been painted, carry on over the remainder of the surface using smooth strokes. Use a large brush to apply the paint and be sure to move it in all directions to work the paint fully into the texture of the render. Most rendered walls will require at least two coats of paint to ensure an even coverage.
