Sika MonoTop-1010 ES – Anchor and repair mortar – 4Kg – Grey

The Sika MonoTop-1010 ES is an anchoring and repair mortar produced by the company Sika. This product is specially designed to provide excellent adhesion and serve as a passivation activator for concrete reinforcements. It is part of Sika’s range of products intended for the repair and protection of concrete structures and is formulated to meet the strictest standards in terms of durability, strength, and corrosion protection.

Main Features of Sika MonoTop-1010 ES

• Anchoring and anti-corrosion protection mortar: This mortar is applied as a bonding layer between the existing concrete and the repair material, optimizing the adhesion of repairs. At the same time, it acts as a protective barrier against corrosion for steel reinforcements.
• Ready to use and easy to mix: Sika MonoTop-1010 ES is a single-component product, meaning it is ready to use with just the addition of water. This feature simplifies preparation and reduces mixing errors.
• Excellent adhesion: The product is formulated to adhere firmly to concrete substrates and steel reinforcements. This strong adhesion contributes to the durability of the repair, even in aggressive environments.
• Corrosion resistance: As a protective mortar, Sika MonoTop-1010 ES protects steel reinforcements from corrosion through its alkaline formulation, which creates effective passivation of metal surfaces, essential for environments exposed to moisture and aggressive agents.

Advantages of Sika MonoTop-1010 ES

• Versatility: Sika MonoTop-1010 ES can be used both as a bonding primer and as a layer of anti-corrosion protection for reinforcements, simplifying repair steps and reducing the need to purchase multiple different products.
• Compliance with concrete structure protection standards: This product is designed to meet the requirements of European standards for concrete repair and protection (EN 1504). This ensures quality and durability compliant with international standards.
• Compatibility with other Sika products: Sika MonoTop-1010 ES integrates perfectly into Sika’s repair systems, particularly with other products from the MonoTop range, allowing for complete and consistent repairs for concrete structures.
• Corrosion prevention: By providing effective corrosion protection, the product helps extend the lifespan of reinforced concrete structures, particularly in environments where structures are exposed to de-icing salts, chlorides, or moisture.
• Easy application: It can be applied with a brush or roller, allowing for great flexibility of application and making it easy to use on surfaces of various sizes and shapes.

Common Applications of Sika MonoTop-1010 ES

Sika MonoTop-1010 ES is commonly used for:

• Repairing reinforced concrete structures: For any type of structure, whether buildings, bridges, or marine structures, this product ensures enhanced protection against corrosion and improves the adhesion of repair concrete.
• Structural and aesthetic repairs: It is suitable for structural repairs where strong adhesion and corrosion protection are needed, but it can also be used for maintenance work on concrete.
• Aggressive environments: Particularly useful in areas where concrete structures are exposed to chlorides, such as parking lots, marine infrastructures, and coastal areas.

Application Method of Sika MonoTop-1010 ES

• Surface preparation: Before application, concrete surfaces must be carefully prepared to remove dust, oils, greases, and other contaminants. Damaged areas must be cleaned of loose parts and cleaned.
• Mixing: The product should be mixed with the recommended amount of water until a homogeneous and lump-free consistency is achieved. A mechanical mixer is recommended for optimal mixing.
• Application: Apply a first coat of Sika MonoTop-1010 ES on the steel reinforcements to ensure anti-corrosion protection. Then, apply a second coat for complete coverage if necessary. For concrete surfaces, apply the product as a bonding primer, then proceed with repair work using the appropriate mortars.
• Drying time: Sika MonoTop-1010 ES has a relatively fast drying time, allowing the next step of the repair work to proceed without too long a wait. Adhering to drying times is essential to ensure optimal adhesion and protection.

Mechanical Properties

• Compressive strength: Approximately 15 MPa after 28 days, making it ideal for ensuring a strong bond between the substrate and the repair mortar.
• Flexural tensile strength: Approximately 3 MPa after 28 days.
• Adhesion to the substrate: Very high, with a tensile adhesion of over 1.5 MPa, ensuring a good bond between the existing concrete and the repair mortar.

Application and Implementation

• Consistency: Paste-like mortar, easy to mix with water, facilitating application.
• Water dosage: 4.75 to 5.25 liters of water for a 25 kg bag, allowing for the desired consistency.
• Mixing time: Mix for about 3 minutes for a homogeneous consistency.
• Application: Applied with a brush, roller, or by spraying. Once applied, the product acts as a binder before the placement of a repair mortar.
• Application thickness: Approximately 1 mm, with a uniform application for optimal adhesion.

Curing Properties

• Setting time: Approximately 2 to 3 hours depending on temperature and humidity conditions.
• Final curing: Achieves optimal properties after about 28 days.
• Open time: Approximately 30 minutes, providing enough time to apply the repair mortars.

Protection Properties

• Steel protection: Prevents corrosion of the reinforcements, thus extending the lifespan of reinforced concrete structures.
• Corrosion inhibitors: The product contains inhibitors to limit the oxidation of steel, particularly useful in environments exposed to corrosive agents such as de-icing salt or industrial atmospheres.

Resistance to Environmental Conditions

• Application temperature: Between +5 °C and +35 °C to ensure good curing and optimal adhesion.
• Durability: Resists freeze-thaw cycles, chlorides, and sulfates, making the product suitable for severe environments such as bridges, tunnels, and coastal structures.

Support Preparation

• Preparation: The surface must be clean, free of dust, oil, grease, and non-adhering particles. For application on steel reinforcements, the steel must be cleaned and free of any rust.
• Pre-humidification: The substrate should be moistened before application to enhance adhesion without leaving standing water.

Packaging and Storage

• Packaging: Available in 25 kg bags, facilitating handling on construction sites.
• Storage: Store in a dry and cool place, protected from moisture. The shelf life is approximately 12 months in its original unopened packaging.

Standards and Certifications

• Compliance: Complies with European standards for concrete repair materials, ensuring quality and durability suitable for infrastructure projects.
• Product class: Certified according to the requirements for corrosion protection of reinforcements and bonding bridges for repair mortars.

Recommendations and Precautions

• Temperature: Apply the product under favorable temperature conditions, generally between 5 °C and 30 °C, to ensure proper setting.
• Avoid excessive mixing: Sika MonoTop-1010 ES should not be diluted beyond the recommended proportions, as this could affect its adhesion and corrosion protection properties.
• Protection during drying: Protect the treated area from the weather, such as rain, during the drying time to prevent the product from losing effectiveness.

In summary, Sika MonoTop-1010 ES is an excellent choice for construction professionals seeking a reliable product for the repair and protection of concrete structures. Its ability to ensure strong adhesion and anti-corrosion protection makes it essential for durable repair projects and conservation of structures exposed to harsh environmental conditions.
