Mold on plasterboard walls - what is the risk?

Mold on plasterboard is very expensive to eliminate. What damage patterns are typical, and where the greatest danger with mold on Rigips components is, read in this post. In addition, why mold on Rigipswänden even in the new building is not so rare.

Mold on Rigips

Rigips is a material that is a very good habitat for many types of mold. Many molds can digest cellulose and feed on it. On top of this, they not only find a habitat on plasterboard, but also a fertile ground on which to spread quickly.

Prerequisites for mold growth

Mold forms especially when moisture is involved. Moisture is the fundamental cause of mold. As Rigips often dries only slowly, the nutrient medium also lends itself for a long time to the mold as home. The formation of the mold can be done very quickly because mold spores are practically ubiquitous. Out of them develops the visible mold.

Dangers on plasterboard walls

Rigips walls are very quickly attacked by mold when they are moist. The infestation progresses quickly and can hardly be stopped. It is important to note that the superficially visible mold is only part of the problem - the entire extent of the mold infestation is not always immediately visible.

Mold behind plasterboard walls

A memorable study has found that even in completely intact surfaces of Rigips found in 90% of cases, the infestation of several mold fungi behind the plasterboard and in the interspace of stem plates. The load was partly massive, even if no traces were visible on the surface.

Stachybotrys chartarum

This extremely dangerous mold fungus species, which is usually black or blackish colored, is preferred on plasterboard. In some cases, this mold has already led to deaths in babies, many others were seriously ill. This is due to mycotoxins (the fungal toxins) that make up the Stachybotrys species. They damage even the smallest amounts. Even dead spores trigger symptoms with the Existing Toxin.

Symptoms of Stachybotrys

An infection even with the least amount of fungal toxins (absorption via the skin or by inhaling the spores):

  • Nosebleeds, pulmonary haemorrhages, shortness of breath
  • severe pneumonia
  • Arrhythmia
  • massive immune defenses
  • occasionally also loss of logical thinking and memory, Alzheimer's progresses very quickly
  • Decrease in white blood cells
  • Flu-like symptoms, fatigue, hair loss, mouth ulcers
  • Redness and swelling of the facial skin, inflammatory and oozing skin diseases

The disease begins with the ulcers in the oral mucosa, then it comes to reduction of white blood cells and later to reduce blood clotting. Left untreated, the disease can lead to death thereafter, because no more food intake is possible.

Disposal of GK plates

As a layman can never be sure that Stachybotrys has not spread on or behind the gypsum plasterboard concerned, extreme caution is required during the refurbishment.

Disposal necessary

It is imperative that panels are completely and extensively dismantled - drying is foreseeable. If an infestation is likely, the parts of the framework must be completely removed. Disposal should be carried out by experienced specialist companies, it is essential to work with complete protective clothing and appropriate respiratory protection. The disposal always takes place in special, tear-resistant bags and avoiding any development of dust.

Tips & Tricks

Do not risk taking mold on rigs, but be very careful. Note that the mold may have already spread to adjacent components, and remove in any case, large-scale.
