Does Cracked External Rendering Or Plastering Lead to Dampness?

External rendering or otherwise known as plastering helps in protecting our homes or buildings in mainly two methods. The first function of a well-installed render or plaster is to insulate your home interiors so that even during extreme heat or cold, you’re not affected.

The second function that the external render involves weather-proofing the brickwork of your home. Thus, the render acts as a protective covering for your building bricks, so that the wall remains durable & dry. It should be known that a cracked render will always pave the way for vulnerabilities, such as increasing the risk of dampness as well as crumbling brickwork.

The Reasons Why Cracks Appear On Render Or Plaster?

Professional interior plastering in auckland services states that any crack in the render is usually caused by very small movements in the building’s foundation. Even though such a phenomenon is totally normal, it is caused by hot & cold spells on the ground.

Such a slight movement tends to cause hairline cracks in your plaster or render. Moreover, plaster made from cement tends to be much more vulnerable than lime-based render.

Should You Consider Hairline Cracks To Be An Issue?

In a nutshell, yes.

Most hairline cracks start out small and over time, such cracks tend to grow bigger and larger, leading to the destruction of your entire building’s integrity. That’s why it’s extremely essential that you take such a problem seriously and mend it as quick as you can because postponing it will make the situation worse.

Does The Crack On The Plaster Leads To Dampness?

Yes.

This is because the cracks in the render allow water from external sources (such as rain or snow) to enter and thereby the moisture gets trapped between the brickwork and the render. When such moisture intrusion goes unchecked, over time it leads to dampness because it soaks the external brickwork.

Some of the major symptoms that you can look into:

• Presence of black mould in various areas of the wall.
• Any patches of dampness that can get pronounced in wet conditions or weather.
• The overall plasterwork will feel damp to your touch and may even crumble sometimes.
• A damp-filled odour inside your home.
