Sika MonoTop®-4052 - Fibre-Reinforced Concrete Repair Mortar
Verified by manufacturer 26 days ago
EPD
Certificate type
High-performance structural concrete repair mortar and screed with improved sustainability, designed for horizontal surfaces
Application
Used to repair all types of reinforced concrete structures and components for:
- Buildings.
- Car park decks.
- Civil engineering structures.
- Dams and bridges.
- Marine structures.
Used for:
- Restoration work (Principle 3, method 3.1 and 3.3 of EN 1504-9). Repair of spalling and damaged concrete in infrastructure and superstructure works.
- Structural strengthening (Principle 4, method 4.4 of EN 1504-9). Increasing the bearing capacity of the concrete structure by adding mortar.
- Preserving or restoring passivity (Principle 7, method 7.1 and 7.2 of EN 1504-9). Increasing cover with additional mortar and replacing contaminated or carbonated concrete.
Description
Sika MonoTop®-4052 is a one-part, cementitious, fibre-reinforced concrete repair mortar and screed. It contains recycled supplementary cementitious materials and can therefore contribute to reducing the carbon footprint of the application.
Features and benefits:
- Uses recycled raw materials.
- Layer thickness 6 to 120 mm.
- Low drying shrinkage and very low sensitivity to cracking (can be applied up to 300 m² without joints).
- Sulphate-resistant.
- Suitable for internal and external applications.
- Contains corrosion inhibitors.
- Compatible with cathodic protection systems.
- Application by hand, or by machine.
- Easy to apply - effortlessly levels when worked, ideal pot life and smooth finishing.
- High abrasion resistance (when used with Sikafloor®-140 W Troweling Primer).
- Dust-reduced for cleaner, healthier environment.
- Good resistance to sea water.
- Low permeability.
- Excellent freeze-thaw resistance.
- EuroClass A1 reaction to fire rating.
- Class R4 to EN 1504-3.
- Class CT-C60-F8-A9 of EN 13813.
- Early trowelling after three hours at +20°C.
- Overcoatable with epoxy after only 24 hours (when Sikafloor®-140 W Troweling Primer is used and the product is maintained at >+10°C).
- Can be trafficked directly when installed with Sikafloor®-140 W Troweling Primer (it is recommended that the surface is sealed with a Product from the Sikafloor® ProSeal Range to prevent staining, which can also act as a curing agent if not overcoating).
