What color is water resistant gypsum wallboard?

Water-resistant gypsum wallboard is typically colored green. This distinctive color aids in its identification as a product designed to withstand moisture better than standard gypsum board. The green color is a result of a special coating applied to the surface and is an important feature that signals to contractors and builders that this particular wallboard is suitable for areas with higher humidity, like bathrooms or kitchens.

In construction, using the appropriate materials for specific environmental conditions is crucial for ensuring the longevity and durability of structures. By choosing water-resistant gypsum wallboard, builders reduce the risk of mold growth and material degradation, which can occur in moist conditions. The identification through color helps to prevent misuse and ensures that the right type of wallboard is utilized in suitable applications.
