What Is SikaTop Seal-107 (A+B) SikaTop\u00ae Seal-107 is a 2-part cementitious waterproofing system supplied as a 25kg set: 5kg Part A \u2013 Liquid polymer component 20kg Part B \u2013 Cement-based powder component When mixed together, they form a brushable or trowel-applied waterproof mortar slurry that bonds strongly to concrete, mortar, and masonry. It is specifically engineered to: Create a watertight barrier Resist moisture penetration Protect concrete from carbonation Provide durable and flexible waterproofing For Ghanaian contractors searching for cementitious waterproofing, waterproof mortar slurry, or water tank waterproofing solution, this product provides a reliable and proven system. Product Composition and Technical Structure SikaTop Seal-107 is a polymer-modified cementitious coating. Composition details: Part A: Liquid polymer Part B: Cement-based mix The polymer modification enhances: Flexibility Adhesion Crack-bridging capability Durability The cementitious component ensures: Strong mechanical bond to substrate Breathability Structural compatibility with concrete and masonry Unlike bituminous or membrane systems, SikaTop Seal-107 becomes an integral bonded layer to the surface. Coverage and Material Consumption Coverage depends on thickness and application method. General guideline: Approximately 2.0 kg per mm thickness A 25kg unit typically covers a significant area depending on final thickness and substrate condition. For waterproofing systems: Apply at least 2 coats Total thickness: 1.5 to 2.0 mm Accurate coverage calculation should consider: Surface roughness Absorption level Application method (brush or trowel) CETECH Ghana provides assistance with quantity estimation for projects of all sizes. Core Performance Advantages SikaTop Seal-107 offers multiple technical benefits for Ghana construction projects. Flexible Waterproof Barrier Forms a continuous waterproof coating Resists water penetration under positive pressure Maintains flexibility compared to rigid cement coatings Durable Protection Long-term performance in wet environments Suitable for interior and exterior use Protects against moisture damage Breathable System Allows water vapor diffusion Reduces blistering risk Minimizes trapped moisture issues Carbonation Protection Protects reinforced concrete from carbonation Helps extend structural lifespan Potable Water Approved Suitable for water tanks and reservoirs Safe for potable water applications Ideal Applications in Ghana SikaTop Seal-107 is widely used across multiple sectors in Ghana. Water Tanks and Reservoirs Overhead concrete tanks Underground reservoirs Potable water storage Wet Areas Bathrooms Kitchens Toilets Shower areas Foundations and Basements Foundation walls Retaining walls Basement interiors External Masonry Rendered walls Blockwork Concrete facades Industrial and Commercial Use Manufacturing facilities Mining infrastructure Oil and gas facilities Agricultural water structures Emergency and Disaster Preparedness Emergency water storage systems Flood-prone foundation protection Rapid waterproof repair projects Surface Preparation Requirements Proper surface preparation is critical for performance. Substrate must be: Sound Clean Free of dust, oil, grease, and loose particles Surface condition requirement: Pre-wetted Surface Saturated Dry (SSD) SSD means: Surface is damp No standing water Pores are filled but not flooded Correct preparation ensures: Strong bond Uniform curing Maximum waterproof performance Mixing Instructions Mixing must follow the correct sequence. Step-by-step mixing: Add Part A liquid to a clean mixing vessel Gradually add Part B powder Mix using a low-speed drill Mix for 2\u20133 minutes until uniform Important: Do not add extra water Do not overmix Use clean tools Correct mixing produces a smooth, workable slurry. Application Guidelines Application is straightforward for trained professionals. Application methods: Brush Trowel Coating requirements: Apply at least 2 coats Achieve total thickness of 1.5 to 2.0 mm Environmental conditions: Do not apply in direct sunlight Do not apply under heavy wind Protect freshly applied coating Tool cleaning: Clean tools with water immediately after use Proper curing and protection ensure long-term durability. Why SikaTop Seal-107 Performs Well in Ghana\u2019s Climate Ghana\u2019s climate presents challenges: High humidity Heavy seasonal rainfall Temperature fluctuations Coastal exposure in some regions SikaTop Seal-107 performs effectively because: It bonds tightly to substrate It resists moisture ingress It remains breathable It protects against carbonation This makes it suitable for both inland and coastal construction projects. Comparison With Other Waterproofing Options in Ghana Common waterproofing options include: Bituminous coatings Torch-applied membranes Acrylic waterproof paints Crystalline waterproofing admixtures Cementitious coatings Advantages of SikaTop Seal-107 over membranes: No seams Fully bonded system Easier detailing around corners Suitable for potable water Advantages over basic cement coatings: Polymer-modified for flexibility Better crack resistance Stronger adhesion For concrete water tanks and wet rooms, cementitious waterproof mortar slurry systems like SikaTop Seal-107 are often preferred. Durability and Lifespan When applied correctly: Provides long-term waterproof protection Resists mechanical wear in typical service conditions Maintains adhesion over time Factors influencing lifespan: Proper substrate preparation Correct thickness Proper curing Protection from physical damage In Ghana\u2019s building conditions, durable waterproofing significantly reduces maintenance costs. Sector Applications Beyond Building Construction Manufacturing and Industrial Facilities Process areas Water containment Chemical exposure zones Mining Sector Water management structures Equipment wash areas Oil and Gas Concrete containment structures Storage infrastructure Agriculture Irrigation tanks Livestock water systems Warehousing and Logistics Service areas Damp-prone floors SikaTop Seal-107 supports high-performance waterproofing across sectors.
