Zydex Zycosil Max — 100% reactive organosilane nano-sealer waterproofing

Zydex Zycosil Max is a next-generation, 100% reactive organosilane nano-sealer from Zydex Industries — engineered for high-performance architectural waterproofing on concrete, masonry, and plaster surfaces. Unlike conventional water repellent coatings that form a physical surface layer, Zycosil Max penetrates deeply into the cement matrix to make the structure inherently hydrophobic.

Its formula penetrates 3 to 4mm deep inside concrete and plaster substrates, chemically interacting to become an integral part of the structure — meaning a separate membrane layer is often unnecessary. It transforms the surface chemistry from hydrophilic to hydrophobic, effectively sealing microscopic pores and nano-cracks from within.

Unlike typical polymer coatings that trap moisture, Zycosil Max acts like a breathable skin — blocking liquid water ingress from the outside while allowing internal structural moisture vapours to safely escape. Being 100% UV-resistant and non-leachable, it completely eliminates common peel-off, flaking, and blistering issues — delivering truly permanent, maintenance-free water repellent protection trusted by applicators and contractors across India as a dependable construction chemical for facades, terraces, exterior walls, and exposed concrete structures.
