Waterproofing Coating/Sika Top Seal 105

Two-Component System: SikaTop-105 comes as a pre-batched kit consisting of two parts: a liquid polymer component (A) and a cement-based powder component (B) with selected aggregates. These two parts are mixed on-site to create a waterproof slurry. No additional water is needed. ​Polymer-Modified: The addition of a polymer to the cement base enhances the product's performance. It improves its flexibility, adhesion to the substrate, and overall waterproofing capability. ​Dual-Action Waterproofing: The product works by combining two mechanisms: ​Crystallization Action: It creates a pore-blocking effect within the concrete or masonry, which helps to prevent water from penetrating the substrate. ​Polymer Waterproofing: The polymers create an impermeable membrane on the surface, further sealing it against water.
