Aerated block walls are notorious water sponges. Primer applied on them gets sucked dry within minutes. The paste dries before it can penetrate or form a film. The result is weak sealing, surface dusting, and poor adhesion for the layers that follow. The problem is not the primer itself. It simply never gets the chance

Hydroxypropyl Methylcellulose (HPMC) functions as a non-ionic cellulose mixed ether. Due to specific properties—namely high water retention, thickening, film-forming, and binding—HPMC has become an essential functional additive across the construction, pharmaceutical, and food industries. This analysis examines the core mechanism of HPMC water retention, real-world applications, and the specific markers of a premium product. 1.
