    Lavarep F60 high strength fiber reinforced concrete repair mortar by MATEX

    Lavarep F60

    High Strength Fiber Reinforced Concrete Repair Mortar

    LAVAREP F60 is a high-strength, polymer-modified, fiber-reinforced, shrinkage-compensated mortar engineered for durable patching and structural repairs. Formulated with hydraulic binders, graded aggregates, silica sand, additives, and fibers, this single-component mortar mixes easily with water and applies well to vertical, overhead, and horizontal surfaces. Its thixotropic properties allow for precise application without formwork, while the shrinkage-compensated formula reduces cracking risk. LAVAREP F60 delivers excellent mechanical strength and impact resistance, making it ideal for repairing worn or damaged concrete elements exposed to high mechanical stress and aggressive environments.

    How to Apply Lavarep F60

    Lavarep F60 is mixed with clean water and applied by trowel, spatula or mortar spray machine to a prepared, saturated surface dry (SSD) substrate.

    1. Cut and break out. Mark the boundary of the damaged concrete and cut neatly with a saw cutting machine or disc grinder to a depth of 10 mm; feather edges are not permitted. Chip the concrete within the boundary down to a sound base and fully expose corroded steel including the rear of the bar.
    2. Clean and treat reinforcement. Clean the substrate of grease, contaminants, oil and loose material with a steel brush; use sand blasting on the reinforcing steel for deep rusting. Immediately coat the cleaned steel with one coat of Lavazinc EP or Lavafer, and add bars where the section is reduced by oxidation.
    3. Saturate and prime. Soak the substrate with water and let excess drain or evaporate to a saturated surface dry (SSD) condition. For superior bond, apply a Megabond SBR slurry bonding coat before the repair mortar.
    4. Mix. Pour 3.75-4.25 liters of clean water into a container and slowly add the 25 kg bag. Mix with a spiral paddle on a slow-speed heavy-duty drill until homogeneous and lump free; always add powder to water and do not add extra water.
    5. Apply. Force the mortar lightly into the prewetted substrate with a trowel or spatula: about 5 mm minimum, up to about 50 mm vertical, 20 mm overhead and 5-100 mm horizontal. For a second coat, cross-hatch and roughen the previous layer and let it take its initial set.
    6. Spray large areas (optional). For large repair areas the mortar can be sprayed with a mortar spray machine. Check the gauging water and apply a sample area to confirm consistency and bond before full application.
    7. Cure. Protect the repair from drying winds, sun or excessive heat. Cover with wet hessian cloth and polyethylene sheet for two days, or apply a recommended MATEX curing agent.
    8. Clean tools. Clean tools with water before the product hardens; hardened material can only be removed mechanically.

    Frequently Asked Questions

    What is the compressive strength of Lavarep F60?

    Lavarep F60 achieves >40 N/mm² at 7 days and >60 N/mm² at 28 days, tested to ASTM C109. Flexural strength is >9.0 N/mm² at 28 days (ASTM C580).

    What thickness per coat can Lavarep F60 be applied at?

    Thickness per coat is 5-50 mm vertical, 5-20 mm overhead and 5-100 mm horizontal.

    How much water is needed to mix Lavarep F60?

    Add 3.75-4.25 liters of clean water per 25 kg bag, always adding powder to water. With 4.0 liters of water one bag yields 13.2 liters.

    What is the coverage of Lavarep F60?

    Lavarep F60 covers approximately 2.2 kg per square meter at 1 mm thickness. Coverage is approximate and subject to site conditions.

    What is the workability time and application temperature of Lavarep F60?

    Workability is 35 minutes at 25°C. Apply between +5°C and +35°C.
