What is Sikatop Seal 107 elastic?
SikaTop® Seal-107 Elastic is a cement-based, two-component, flexible waterproofing coating material. It consists of a liquid polymer component (Component A) and a cement-based powder component (Component B) containing special additives.
When applied to surfaces, it forms a waterproof protective layer that safeguards concrete and mineral-based construction elements against water and moisture effects. Thanks to its elastic structure, it can bridge fine cracks and provide long-lasting waterproofing performance.
