Moisture mapping is a crucial technique used to determine the moisture content within wooden structures. Understanding this content is essential before embarking on painting projects or any other moisture-sensitive applications.
Wood moisture content (MC) refers to the amount of water present within the wood’s cellular structure.
When painting wood surfaces, it is critical to ensure the wood’s moisture content is within an appropriate range. Excessive moisture content can lead to peeling, blistering, and cracking of the paint film.
Generally, the optimal moisture content of wood before painting is between 8% and 12%. This range allows for proper adhesion, flexibility, and durability of the paint. Higher levels of MC can cause premature paint failure.
