Winter construction puts primers to a severe test. In low temperatures, water freezes and expands, damaging the internal structure. Repeated freeze-thaw cycles cause the primer layer to peel, powder, and lose bond strength. Ordinary primers see sharp performance drops below zero, becoming a hidden quality risk for winter work. The synergy between HPMC and RDP
Renovating old tile surfaces is a common need in urban renewal and home improvement. Tile surfaces are smooth, dense, and almost non-absorbent. Standard primers struggle to adhere, and the renovation layer easily debonds. At the same time, vertical application demands a primer that won't sag or drip, which would waste material and stain the tiles.
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
