Low Damp Readings

What is an Acceptable Damp Reading?

Acceptable damp readings vary depending on the material and type of wall being tested. However, a general guideline is that readings below 20% on a scale of 0 to 100 are considered acceptable. Acceptable damp readings for different types of walls include:

  • Concrete walls: 20% or less
  • Plasterboard walls: 15% or less
  • Timber walls: 10% or less

It is important to note that these are just general guidelines. The acceptability of a damp reading may also depend on factors such as the age and condition of the wall, the level of moisture in the surrounding environment, and the presence of any visible signs of dampness.
