What Is SikaTop Seal-107 (A+B)

SikaTop® Seal-107 is a 2-part cementitious waterproofing system supplied as a 25kg set:

• 5kg Part A – Liquid polymer component
• 20kg Part B – 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.

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:

1. Add Part A liquid to a clean mixing vessel
2. Gradually add Part B powder
3. Mix using a low-speed drill
4. Mix for 2–3 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’s Climate

Ghana’s 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’s building conditions, durable waterproofing significantly reduces maintenance costs.
