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 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.
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!
