High temperatures and humidity in enclosed storage or exhibition space may lead to excess moisture that warps the painting. [11] High Humidity reduces mechanical damage such as brittle paint but raises the risks of biological organisms, e.g. white efflorescence and green-to-black stains on a panel painting. [12]
Water-based paints and oil-based paints will cure differently based on the outside ambient temperature of the object being painted (such as a house). Usually, the object being painted must be over 10 °C (50 °F), although some manufacturers of external paints/primers claim they can be applied when temperatures are as low as 2 °C (35 °F). [4]
The representation is made on a temperature-relative humidity, instead of a standard psychrometric chart. The comfort zone in blue represents the 90% of acceptability, which means the conditions between -0.5 and +0.5 PMV, or PPD < 10%.
Historic paint analysis, or architectural paint research, is the scientific analysis of a broad range of architectural finishes, and is primarily used to determine the color and behavior of surface finishes at any given point in time. This helps us to understand the building's structural history and how its appearance has changed over time.
