How MHEC For Plaster Mortar Reduces Mortar Hollow Drumming


Mortar "hollow drumming"—characterized by a hollow sound when a wall surface is tapped—is one of the most common quality issues encountered in plastering projects. In severe cases, it can lead to the detachment or cracking of the surface layer, thereby compromising both the durability and aesthetic appeal of the overall structure. The root causes of this phenomenon are often closely linked to insufficient mortar adhesion, inadequate wetting of the substrate, and excessive moisture loss during the construction process. The application of MHEC (Methyl Hydroxyethyl Cellulose) for Plaster Mortar offers an effective material-based solution for mitigating this problem.
