Things to do before Render Painting Old External Walls

One of the most significant differences between painting and old rendered and newly rendered walls lies in their condition. The older ones are most likely to have some defects in the form of blisters and cracks, crevices and holes here and there.

Therefore, the prep or repairing work before the painting will have to be more extensive in case of the older walls, than their newer counterparts.


The Prep Work – How it will be like?

Well, here is a summary of the typical glitches that you are likely to find on old rendered walls.

  • Loose of Flaky Paints
  • Cracks and Crevices
  • Hollow, swelled or loose render
  • Growth of moss, green and mould on the wall
  • Improper finishing of the previous repairs
  • Additions and alterations to walls and the house as a whole
  • Old redundant nails and clips, brackets and screws
  • Penetrated water and marks thereof and damps on the walls

Therefore, you see, each of these above needs to be addressed in a proper way before the painting is done.

Getting Rid of the Flaky Paint

One of the MUST DO things before render painting older walls is getting rid of the flaky paint. This is extremely important as otherwise; you will only be painting walls with an unsound surface. This means no matter how good is the quality of the paint you use, it will not last long.

Removal of the old paints

In order to get have the best render painting done, you need to have the old paints removed thoroughly. Only then you will have a perfect finish and this involves thorough removal of the coats after coats of old paints. A large variety of tools can be used for that and they range from scrapers to heat guns, paint strippers to brushes with steel fibres.

Filling in the cracks and crevices

These are common properties of the old walls, and they need to take care of – for obvious reasons.  Use a good quality filler to fill in the gaps no matter how negligible and faint they are.

Loose Rendering

It is one of those challenges that demand the intervention of a professional company. They will use appropriate measures to get rid of these loose rendering and prepare the surface for fresh painting.

And then, the pros will obviously take care of the nails and brackets for adding perfection to the surface. They will also put maximum attention to the damps of the wall before getting on with the painting business.

Preparing a Wall for Cement Rendering – the Basics

If you want the cement rendering results to meet your expectations, you need to prepare the wall properly before you start. 

When it comes to wall rendering, things practically starts with preparing the wall. The success and failure of the rendering depend upon the way you prepare the wall. 

Where and how to begin? 

The main reason for having the walls rendered is adding a weatherproof layer to the exteriors and creating a finish, which will be aesthetically smart and will be a treat to watch with some pleasing textures. Once you are done with cement rendering you the walls, finishing it off with a smooth layer or some or other textured materials like some stone chips is a good idea. However, before that you need to prepare the wall properly. 

Washing the wall-

For preparing the wall in question for cement rendering, the first step needs to be thoroughly cleaning the wall and making sure that there are no cracks at the joints of the outer surface. You can try this by tapping gently on the wall, to make sure there is no hollow sound. Walls with cracks or hollow cavities full of air will generate hollow sound. 

In case you hear the hollow sound, you need to peel off that hollow patch either with the help of a screwdriver or with a trowel. It will help you to free the interior of the spot, repair and fill with cement and make it smooth and merge with the rest of the cement layer of the wall. 

The best way is to wash the wall off with the help of a power washer, as the force of water will wash off all the debris and unwanted stuff, making the wall as clear as it can be before the render coat is applied.  

Treating the wall-

When it comes to rendering a wall, you need to ensure that you wash it thoroughly with the help of treatment. This will help the wall prevent the growth of plants and mould infestation in the future. Putting a coat of lime solution on the surface before solid plastering is another useful and crucial step. It will help in bonding and applying additional coats thereafter. The preparation to render the wall should continue for at least 4 to 5 days before any rendering layer is applied.  

Putting the first coat-

Technically speaking, putting the first rendering coat on the wall is also a part of preparation before rendering. The rendering applied needs to be a thin one, varying from 8 to 10 mm in thickness. 

The first rendering score needs to be applied in diagonal strokes so much so that it creates a surface rough enough for the subsequent coats to be applied.

Is there any Difference between Rendering and Solid Plastering?


This is a confusing question for most of the Aussies.

It’s summer in Australia right now. Time for some holidays that people will love to utilise for carrying out the makeover of both house exterior and interior. But, there is always a duality that remains regarding the choice between rendering and solid plastering.

Can Rendering be Done on Interior Walls?

Common perception says that the major difference between these two techniques is while rendering is for the exterior wall, the solid plastering is done on the interior walls. However, it is just the traditional definition. In recent times, 3D rendering can be effectively done on the interior walls too. All you need to do is to make sure is to get in touch with the best renderer in Brisbane and get the work done within the schedule.

Which is better among these two options? Is there a difference in the material or the technique of both these type of wall covering? And, most importantly, which one offers better longevity than the other? Don’t get fussed around these questions. Go through the following and resolve your queries right away.

Difference in Composition

Most of the people tend to believe that the difference between plastering and rendering is in the material. However, in reality, both the material is the same. But, it differs in the composition of the material. Lime gypsum, cement and sand are three main elements in rendering. For this process, the percentage of cement remains high. On the contrary, for solid plastering in Brisbane, the experts use less amount of cement for a smooth texture.

Cracking Tendency

When it comes to after effects of both the services, you have to consider the cracking issue. For plastering, the cracking tendency is high. It happens when a lot of people start working on the freshly plastered walls without letting it dry out. In such cases, you have to be a bit careful.

However, in rendering, the chances of cracking is of course less. The reason is rendering sits on the wall faster than anything else.

Apart from these two fundamental differences between rendering and solid plastering, there are not much of a difference. The purpose is, of course, different, and therefore you can choose both based on your specific requirements.

The 4 Myths Debunked That Surround Wall Plastering

Plastering a wall after it is built is known to prevent it from the changing effects of the weather and protect the wall to stay intact. It provides a protective layer on the brick and mortar wall. With a plastered wall, you get to prevent moisture build-up, pest attack and get to maintain the overall aesthetics of the wall.

Well, plastering the walls is often left to the professionals for solid plastering in Brisbane who ensure that you do not have to worry about the walls deteriorating in quality as well as aesthetics. Making it a DIY task doesn’t bring out the best results especially when you aren’t skilled with it.

While plastering is something that all home builders opt for, there are numerous myths associated that misleads homeowners. Here is a quick discourse that clears the air.

Myth 1 – The Wall Requires Sanding After It Is Plastered By the Experts

Sanding a wall means smoothing the surface and removing any coarse texture. While several suggest that a freshly plastered wall requires sanding for it to stay intact in its place. This is a myth that people need to stop believing in. Why would you want to sand a plastered wall where it is already smoothed? It would ruin all the efforts that you put in when plastering it in the first place. Therefore, plastering a wall doesn’t require sanding especially when you are allergic to dust. Sanding results in dirty interiors and upholstery which can result in messy interiors.

Myth 2 – Anyone and Everyone Can Be a Plastering Expert

Well, just by watching tutorials and taking help from guidebooks, no one can become a plastering expert. It requires professional help when it comes to attaining perfection for the plastering of the walls, and that is why the need for professional help becomes imperative. They are known to own the right equipment as well as the skills which make them the right choice for any house building task. They are aware of how the plaster is to be applied and how a smooth finish can be attained. With help on not just the plastering, they are also known to help with the care that a wall requires after being plastered.

Myth 3 – Any Size of Trowel Serves the Purpose

No, not all trowels serve the purpose of plastering a wall. When it comes to plastering, there is this specific type of trowel that is put to use by the experts. It is said that the trowel is to be worn in and only then would it give a smooth and even texture while covering a larger wall area at a single go. Any given trowel wouldn’t come up with the right results, and that is the reason why there is the need to pick the right type of trowel.

Myth 4 – Rendering and Plastering Are the Same. (They Are Synonyms)

This is something that needs to be cleared properly. When it comes to rendering, it involves the outer walls of a building, but plastering involves sealing a wall from the insides. Experts for rendering in Brisbane agree that they may serve the same purpose but aren’t synonyms by any chance. For plastering, the texture is smooth, but for rendering, it is coarse and rough to withstand the harsh weather.
