How to Get a Professional Looking Finish with Cement Rendering

The weather in Australia can be harsh. From scorching heat during the summer to rain and wind during winter, the elements can take a toll on your home’s exterior walls. One way you can protect your house against the elements is by applying a coating that can act like a barrier against the heat, rain, and other weather changes.

And, that coat can come in the form of cement render.

If you are not new to rendering projects, then you may be wondering how you can make your work look better. More specifically, how can you give a more professional finish to your cement rendering project.

In this article, we will provide a few tips that can help you achieve just that.  

Types Of Rendering

There are several types of renders available and the material and type of surface they are applied to can determine how well the finish will turn out and how long it will last. Deciding on this detail can make a big difference in how the render will look like.

Here are the most types of renders:

  1. Concrete rendering
  2. Acrylic rendering
  3. Polymer rendering

What Is Concrete Render And What Is It Used For?

Concrete renders result from a mixture of sand, water, and lime or clays. It is mostly used on hard surfaces, such as concrete, brick, or stone, sometimes also on walls that have been painted and sanded well beforehand. This render gives a smooth finish look.

Concrete plaster can also be used on retaining walls, fences, as well as interior and exterior walls.

Advantages Of Cement Rendering

Here are some of the reasons why you should opt for cement rendering:

  • Provides a cleaner, smoother, and more aesthetically pleasing finish on hard surfaces than the other two options;
  • Can be produced in a wide variety of colours (if you choose to use coloured pigments;)
  • Can be found in several textures, from a smooth finish to a textured finish (depending on the sand size added;)

How To Do A Rendering Job Like  A Pro 

First, you will need a few tools, such as a metal spatula, wooden trowel, plasterer’s hammer, styrofoam float, a soft brush, a steel brush, measuring tape, and others. 

1. Prepare the Wall

If the wall is chipping remove all the old plaster then wet the wall with a hose. This process helps to remove dust and old plaster debris.

New plaster should be applied to slightly damp surfaces that have been previously coated with PVA-type liquids. This can speed up the adhesion and optimum drying of the plaster over time.

2. Mix the Ingredients

Use 1 part hydrated lime to 3 parts sand. Several additives can make your mixture (and therefore your plaster) more waterproof and easier to handle, but it would be better to discuss this aspect with a specialist. 

To get the desired result, make sure you mix the right quantities and mix them extremely well.

3. Apply a Coat of Rendering 

Apply the plaster in two layers. Be careful when applying it to ensure that it actually sticks to the wall, and does not fall off. 

Before the first coat hardens, use a notched trowel to create some lines in the cement. This helps the second layer adhere better.

4. Apply the Finishing Coat 

After the first coat has hardened, wet the wall again and apply the next coat. This topcoat should be softer than the first. For a smooth finish use a sponge or trowel to smooth out excess material before it hardens.

Although it seems simple enough to render a wall, it can cause quite a lot of problems if you don’t consider all the factors before you start, from the weather to the quality and quantity of materials.
