Porous vs Non-porous Materials for Mould Remediation

Porous vs Non-porous Materials for Mould Remediation

The difficulty of cleaning mould depends on the surface it is on. When a mould outbreak occurs, it will try to latch itself onto whatever surface it is on by creating ‘roots’. Much like garden weeds, if mould finds holes within the surface it is on, it will make its removal much more difficult.   

Types of Material Mould Latches Onto 

There are two different surface material types; porous and non-porous. How do we tell the difference between porous and non-porous materials? Generally, if a material repels water, it is considered non-porous as porous materials absorb water. Porous materials are full of tiny holes or pores which make them permeable to outside forces i.e., mould. Non-porous materials are the opposite, where mould cannot pass through and instead sits on top of it. Because of this, non-porous materials are easier to clean than porous materials. Mould can live further inside porous materials which makes its cleaning harder as a deeper reach is needed.

Common Beliefs and Frequently Asked Questions 

  1. If my surface is hard, is it non-porous?

A common misconception is that if a surface is hard, it must be non-porous. The issue with this is that the naked eye cannot perceive all the holes and crevices each material holds. Granite, for example, can be a very hard material but is still porous and highly susceptible to deep mould infestations. Therefore, it is important to understand what type of material is being treated for mould, as there are many types of hard materials that may still be porous. 

  1. Can bleach solve my mould problems?

In certain situations, bleach can eradicate most species of mould; however, since bleach is not safe on fabrics and metals, it cannot be recommended for cleaning out mould outbreaks. Bleach can also be harmful to your health by causing respiratory and eye irritation, so its use should be done with caution. 

  1. When Can I expect mould to grow? When there’s…
  1. Extended rainfall 
  1. High humidity 
  1. Aircon leaks 
  1. Dark and damp conditions 
  1. No ventilation 

Cleaning Solution 

Once the type of mould-affected material has been identified, it is important to note that there are specific processes that go into cleaning each type of surface. Even if porous materials may require more time and detail with their disinfection and cleaning process, hard surfaces must also be treated with care as they can become damaged if not cared for properly. Therefore, restoration and cleaning professionals need to first identify what type of material mould has affected, then move on to creating an efficient process to remediate the affected object. The most certain way to remediate your mould-affected object is to contact a professional today and identify what type of surface they need to deal with.
