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.

Only then you will have a perfect finish and this involves thorough removal of the coats after coats of old paints.

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.

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.

Have you ever thought of the hidden secret behind attractive interior walls? It’s actually the textured render finish that transforms your interior walls and brings life to space. To know what rendering is in particular read through the lines below in detail. 

Rendering is a mixture of cement, lime and water that is applied usually on brick walls to give a smooth finishing touch. If solid rendering is done before applying paint on walls, you can even get the flawless paint job you have ever imagined. However, the choice of render finish depends upon individual requirements and other factors. 

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. A coat of textured render finish can bring back the aesthetics and texture of your walls like new.

  • Prevent Damp: If you overlook interior rendering while renovating your home, it can invite a lot of potential damages. Unpainted brick walls allow water to penetrate that eventually causes damp and cracks in walls. It becomes prominent, especially during the rainy season when water seeps into the walls and damage the structural integrity of your property. 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.
