Importance of Primer in APP Membrane Waterproofing
Importance of Primer in APP Membrane Waterproofing Application Enhances Surface Adhesion Primer improves the bond between the concrete substrate and the APP membrane, ensuring better adhesion of the membrane. Dust and Debris Binding It binds loose dust and small particles on the surface, creating a cleaner and more stable base for membrane application. Seals Porous Surfaces Concrete and cementitious surfaces are often porous; primer seals these pores and prevents air or moisture entrapment under the membrane. Improves Waterproofing Performance A properly primed surface reduces the risk of membrane lifting or detachment, thereby maintaining the integrity of the waterproofing system. Increases Durability and Longevity Better adhesion means less chance of failure, leading to longer-lasting waterproofing protection. Reduces Wat...
