As the initial step of rendering job is to prepping, the services need to be patient with their work. If you don’t stress over the necessity of the base management, how do you expect a rendering job to be perfect?

They always pay attention to the usage brush and rollers:

The cement rendering needs gentle brushing off. Putting too much pressure with the brush can destroy the plain finishing of the wall. Some of the unprofessional local services use heavy strokes with brush and rollers. It is not the way to cement rendering restoration process.

  • Using too much sealer in cement:

Some cement rendering service has the notion that using a lot of sealers can make a thick cement paste. And they feel it is the best solution for the rendering. But the mixing can be faulty and turned out to be defective. Sealer in cement used only to retain the moisture so that the rendering doesn’t fall out easily. Another mistake of using a sealer is doing the coating and overcoating haphazardly. You can get rid of this defect only if you use second coat after drying off the first coat of sealer.

Are you using the materials in the wrong proportion?

For cement rendering, professional services use sand, cement, limestone and water. If the service labourers don’t know the exact proportion of mixing these materials, then there will be a high chance of rendering defects. Professionals use the mixing ration of 6:1:1. (6 parts of cement, 1 part of lime and one part of sand)

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.

Some Common Reasons that Cause Solid Plastering on Walls to Crack

solid plastering

Solid plastering develops cracks with time at times. This is a very common phenomenon, and people jump on to hold the rendering company that had done all the work responsible – and very rightly so! The bottom line is, plasters crack due to a number of reasons that have everything to do with the quality of work done by the rendering service provider. 

Here are some of the reasons that are responsible for the deteriorating health of plasters.

Seasonal Change..

Seasonal change is one of the most likely reasons behind cracks in walls with solid plastering. Certain places in Australia see a sharp change in weather during summers and winters. 

This extreme difference and the stark contrast of temperature and humidity levels throughout the year results in contraction and relaxation of materials like bricks and mortars. It has an obvious effect on the solid masonry, leading to the development of cracks all over. 

Shrinkage cracks..

This particular type of crack appears on walls that are freshly solid plastered, in case the walls are not watered properly, more so if the plastering has been done during summer. The water, due to summer heat quickly evaporates, causing the walls to dry out and develop shrinkage cracks. 

Poor construction practice…

This is the reason why it is always so important to give the responsibility of rendering to an expert and seasoned building rendering company. If not, then the incompetent construction professionals would not follow the codal provisions. Here are some examples of bad construction practices by not-up-to–the-mark pros, during plastering. 

  • They would apply plaster without properly preparing the surface
  • They apply a thick layer of plaster on a surface that is uneven and full of dirt and dust, grease, oil or moss  
  • They apply the plaster without using the chicken mess at the joints. 

All these will lead the plaster to develop hairline cracks at first. Then the cracks widen, letting all unwanted stuff to get into the gap thus formed. Then the plaster would pop up and peel off with time. 

And remember, all these happen not after ages following the plastering but within a year or so. It is a disaster, if not anything else, as far as the protection of the walls and your investment are concerned. 

This is the reason you need to put your stakes on an experienced and expert rendering that will do a flawless plastering and will take adequate measures against the obvious woes!

When it comes to renovating a home, most homeowners focus on revamping the house exteriors to enhance the visual aesthetics and often fail to consider the worn-out interior finish. While exterior setups and transformation can uplift the market value of your property, dull and gloomy interiors can leave a negative remark on guests visiting your house for the first time. If you are planning to give a complete makeover to your home, interior render finishes should be given equal importance as it impacts the overall ambience of your property and gives you a positive vibe every time you step inside your home.

How Textured Render Finish Can Bring Lasting Effects on Your Walls

If you have made up your mind to give a stellar makeover to your living space, these undermentioned reasons will compel you to opt for textured render finish instantly.

    • Improve Aesthetics: Rendering is a proven technique to uplift the look of your home. A coat of smooth render can hide all imperfections in walls easily. Even if cracks develop while applying render, they can be re-rendered effectively. However, with time, bricks become shabby and paint begins to fall off.

If you are looking for a textured rendered finish, consult the experts providing professional home rendering for flawless results.

  • Provides Insulation: A coat of fresh render improves thermal regulation inside the house and save your pocket from costly insulation. If you have a stringent budget, it’s better to opt for thermal insulation with rendering other than going for costly exterior insulation. If your property is too old, you can easily go for rendering after every two years to revive its strength.

Choosing textured render finish for your home interiors is a great idea to transform the look and feel of the space along with increasing the value of your property. For further tips on house rendering, keep following our post.

Preparing a Wall for Cement Rendering – the Basics

cement rendering


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. 

Why Wall Rendering & Solid Plastering Need a Thorough and Practical Planning?


If you are looking forward to go for rendering what you need before anything else is a proper planning and while doing so, you need to involve a reputed and seasoned rendering company. You need to make sure whatever you do, the investment is justified and your requirements are truly and honestly met.

However, why it is that you need to make a planning? What it has to do with the success or failure of the rendering job? Here is a sneak peek into the issue.  

There has to be a specification in place beforehand

It is often pretty hard to judge plastering job superficially. And this is true in case of plastering walls as well as ceilings. At times, people waste a lot of time and energy going through the websites and directories, looking for the suitable name and the lowest bidder. But, out of the exuberance, they forget to make a proper planning about the job itself. They forget to decide the type of plastering they need and the extent of wall rendering they will include in their renovation and overhauling. This is a HUGE error that not only leads to imperfection in the work but some unnecessary changes.

Thus, the ideal approach will be to plan properly in advance. And when it comes to planning, it must involve measuring the area that is needed to be rendered, deciding upon the type of rendering that is needed and properly arriving at the budget, depending upon the depth of the coffer.

Once all these are done only then the search for a proper company should begin. Then again, it is important to give all these specification the priority, while zeroing on a suitable name.

Differentiating between bare necessity and luxury

This is a HUGE factor that comes into play during wall rendering process. Though strictly speaking, it is a part of planning, but it has been seen that when there is a lack of planning, the red line between necessity and exuberance becomes all the more prominent. Here is where one has to be cautious and here is where a reputed company, which provides solid plastering or any other form of rendering, comes into play. While it is the responsibility of the property-owner to be rational enough to channelize the budget in a proper way, the rendering companies need to guide them as well to make sure the investment is justified at the end of the day.

And this applies for any form of rendering and here is where there is the need of putting money on quality rendering companies.
