About This Product
SikaTop-107 Seal is a two-component, polymer-modified cementitious mortar applied by brush or roller directly onto concrete or masonry. Because it's cement-based, it bonds well to mineral substrates and is typically used where a rigid, trowel- or brush-applied waterproofing layer is more appropriate than a flexible membrane.
System Role
Waterproofing layer
Used as part of a complete waterproofing system where surface preparation, detailing and correct application are critical to performance.
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.
