Introduction
Type of Building: Public Residential Flats
When a paint exposed to weather disintegrates with the appearance of a fine, loose powder on the surface, which can be readily be wiped off, the slow disintegration caused by loss of binding power of medium at the surface. This is known as chalking.
Chalking happens when paint starts to deteriorate, resulting in a fine, powdery residue on the paint’s surface. This occurs because the paint pigment breaks down and separates from the binder, leading to a loss of color and adhesion. While chalking might seem minor, it can cause more serious problems such as paint failure and increased surface damage.
