The acceptable moisture content range for drywall is between 5 and 12 percent (greater than that and mold can grow). That’s why the average moisture level range for drywall meters starts at 1.5 ...
Excess moisture causes paint to lose its adhesion, pull away from the drywall, and create uneven air pockets. ... If the cause is surface-level—not the result of a crack in the wall and drywall ...
Mold growth can be inhibited by keeping surfaces at conditions that are further from condensation, with relative humidity levels below 75%. This usually translates to a relative humidity of indoor air below 60%, in agreement with the guidelines for thermal comfort that recommend a relative humidity between 40 - 60 %.
The building materials industry also manages the moisture barrier properties in architectural components to ensure the correct moisture levels in the internal spaces of buildings. Optoelectronic devices based on organic material, generally named OLEDs , need an encapsulation with low values of WVTR to guarantee the same performances over the ...
A moisture meter gives a reading of the approximate moisture content of wood. The reading helps in determining whether the wood is suitably dry for its intended purpose. The moisture content reading can also assist in planning a project design that will accommodate future changes in dimension caused by changes in relative humidity.
Drywall can be finished anywhere from a level 0 to a level 5, where 0 is not finished in any fashion, and five is the most pristine. [17] Depending on how significant the finish is to the customer, the extra steps in the finish may or may not be necessary, though priming and painting of drywall are recommended in any location where it may be ...
In North America, troweling joint mud on gypsum panels is a standard construction technique prior to painting wall and ceiling surfaces. Joint compound type and formula selection forms part of a drywall system that can be finished anywhere from a level 0 to a level 5, where 0 is not finished in any fashion, and 5 is the most pristine.

A soluble salts report should include climate conditions and substrate temperature. ISO 8502-6 requires that the test is done at 23 °C and a relative humidity of 50%, with deviations reported and agreed upon by both inspector and customer. During arbitration, absence of these values in a report may render the results invalid.
