SikaTop® Seal-107 is a high-performance polymer-modified cementitious waterproof coating formulated to provide reliable protection against water infiltration. Its two-component system combines cement-based powder with a liquid polymer to create a flexible, durable waterproof barrier suitable for both interior and exterior applications.

This coating adheres strongly to concrete, mortar, brick, and masonry surfaces, helping prevent moisture penetration, surface deterioration, and reinforcement corrosion. It is widely used in waterproofing structures such as water tanks, swimming pools, basements, terraces, wet rooms, and foundations.

Its easy brush or trowel application, excellent adhesion, and durable performance make it a trusted solution for residential, commercial, and infrastructure waterproofing projects.
