How To Identify Water Damaged Plaster

Plaster walls have grown increasingly infrequent and are rarely seen in new construction. However, this classic building strategy was created out of a wooden lath layer coated with many layers of thin plaster. The beauty and increasing rarity of this construction technique are why it is important to protect it, but in many cases, it can be difficult to determine if these walls have suffered water damage. Fortunately, there are signs that you can pay attention to in order to catch water damage early. Here are some to keep an eye out for.

Dripping Paint Stains

These irregular paint stains have a water-like appearance, generally taking a drip-like appearance. They are most often found near a break in the wall, such as where the wall breaks for a window or meets a ceiling. The most common causes are a leak in the plumbing or from the outside.

A Buildup of Efflorescence

Efflorescence is the white deposits left behind when material within masonry is dissolved into water. If this white powdery material builds up on the surface of your plaster wall, this indicates that an excessive amount of moisture is present behind it, seeping through. The efflorescence can be removed. However, the underlying problem will need to be addressed.

Loose or Flaking Paint

If your plaster surface is often painted, a clear sign that plaster has suffered from water damage is to look for paint that is loose or flaking. Most wall paints are insoluble, and if the plaster behind it becomes wet, it can begin to separate and flake or bubble. Often this occurs relatively quickly, unlike with the plaster itself, so if you notice loose or flaking paint, attempt to feel the area underneath the paint and determine if it feels moist.

Mold Infestation

A mold infestation is a definite sign that moisture is present, and this also can pose a severe health risk. Though mold spores are everywhere by the time they grow to a level where the infestation is visible, this indicates that they have had a prolonged or repeated source of moisture on which to thrive. If your plaster wall has developed signs of mold, then a professional will need to remove the plaster in order to treat the underlying area for mold.

Final Thoughts

Water damage can severally impact plaster as well as the health and safety of your home and anyone inside it. Water damage can lead to mold growth and a loss of structural stability for the plaster itself. Before attempting to repair damaged plaster, the underlying source of the moisture will need to first be addressed. After this, often mold remediation will need to be performed in order to prevent the further growth and spread of mold over the surrounding area.
