About This Product
Sika Cemflex is a liquid additive used to improve the water resistance and adhesion of cementitious mortars, renders and screeds. It can be mixed into the gauging water or brushed on as a bonding coat, helping the mortar bond to prepared concrete and masonry while reducing its permeability.
System Role
Waterproofing admixture & bonding agent
Works inside the mortar or as a bonding coat, improving adhesion and water resistance rather than forming a standalone membrane.
Typical Applications
Wet Areas
Waterproofing systems for bathrooms, kitchens, and other continuously wet internal surfaces.
Concrete
Repair mortars, bonding agents and admixtures for concrete protection and structural repair.
Basements
Below-grade waterproofing for foundations, retaining walls, and water-retaining structures.
