SIKA MonoTop 107 Seal 25kg

The SIKA MonoTop 107 Seal Waterproofing Mortar is a two-component mortar used for waterproofing concrete and masonry surfaces. It is formulated with polymer-modified cement and additives, combined with a synthetic resin dispersion, providing excellent adhesion, flexibility, and waterproofing properties. This product is commonly used in various applications, including basements, water tanks, foundations, and surfaces exposed to permanent moisture conditions.

Key Features of SIKA MonoTop 107 Seal:

• Two-component (cement + resin): Comprising a blend of hydraulic cement and liquid synthetic resin, it combines the benefits of both to deliver enhanced performance.
• High waterproofing capability: SIKA MonoTop 107 Seal forms an effective barrier against water penetration and moisture while remaining permeable to water vapor, allowing surfaces to breathe.
• Flexibility: Thanks to the added synthetic resin, the mortar retains good flexibility even after drying, enabling it to withstand small cracks and minor structural movements.
• High adhesion: It adheres to a wide range of substrates, including concrete, brick, stone, and other common construction materials.
• Easy application: It can be applied with a brush, roller, or trowel, making it suitable for various surfaces.

Main Uses of SIKA MonoTop 107 Seal:

• Waterproofing of potable water tanks: Suitable for tanks and other infrastructures in contact with potable water.
• Foundation protection: Protects foundations and basements from water infiltration.
• Waterproofing of buried walls and concrete walls: Protects walls exposed to hydrostatic pressure.
• Terraces, balconies, and pools: Used for waterproofing areas exposed to water, such as pools, basins, or showers.
• Repairing concrete structures: It can also be used to repair superficial cracks or strengthen concrete surfaces.

Advantages of SIKA MonoTop 107 Seal:

• Resistance to positive and negative water pressure: It provides protection against water penetration from both inside and outside.
• Durability: This mortar is designed to withstand extreme weather conditions, ensuring a long service life.
• Compatible with surfaces in contact with drinking water: It is certified for use in applications involving direct contact with potable water, essential for water reservoirs.
• Water vapor permeability: After application, the mortar allows the surface to “breathe,” preventing condensation buildup behind the waterproof layer.

Application of SIKA MonoTop 107 Seal:

• Surface preparation: The surface must be clean, solid, and free from dust, oil, or other contaminants. Significant cracks or holes should be repaired before application.
• Mixing: The product consists of two components—a powder (cement) and a liquid (synthetic resin). These two components must be thoroughly mixed according to the manufacturer’s instructions to achieve a homogeneous consistency.
• Application: It can be applied with a brush, roller, or trowel. At least two coats are recommended for optimal waterproofing.
• Drying time: The drying time depends on climatic conditions, but typically the product becomes touch-dry within a few hours, and full drying occurs after about 7 days. The exact time may vary depending on the applied thickness and ambient conditions.

Packaging:

• Available in 25 kg containers.
• Each set contains the two necessary components to prepare the mortar: the cement powder and the synthetic resin.

Additional Advantages of SIKA MonoTop 107 Seal:

• Ease of use: It is a mortar that is easy to mix and apply, suitable for both professionals and DIYers for small to medium waterproofing projects.
• High performance in humid environments: The product is ideal for applications subjected to constant humidity or regular water infiltration.
• Compliance with quality standards: SIKA MonoTop 107 Seal meets the required standards for waterproofing, ensuring the reliability of the product.

Consumption:

• The consumption depends on the thickness of the applied layers and the type of surface. Generally, for a thickness of about 2 mm, the average consumption is around 2.0 kg/m². It is recommended to refer to the technical guidelines for specific indications on application rates based on surface type and conditions.
