    Lavarep F110 high compressive strength shrinkage free cementitious repairing mortar by MATEX

    Lavarep F110

    High Compressive Strength Shrinkage Free Repairing Mortar

    LAVAREP F110 is a high-strength, single-component, fiber-reinforced, polymer-modified repair mortar designed for structural concrete restoration in high-load areas. Its shrinkage-compensated formula minimizes cracking, while its excellent compressive strength and bonding capacity ensure monolithic repair performance. Suitable for vertical, overhead, and horizontal applications, LAVAREP F110 applies easily without formwork, thanks to its thixotropic consistency. The mortar is highly resistant to acids, gases, and chloride ion diffusion, making it ideal for industrial and marine structures. It offers long-lasting durability and mechanical stability in aggressive environments where superior repair performance is required.

    How to Apply Lavarep F110

    Lavarep F110 is mixed with clean water and applied by trowel, spatula or mortar spray machine to a prepared, saturated surface dry (SSD) substrate.

    1. Prepare the concrete. Remove all grease, contaminants, oil and loose material using mechanical tools. To avoid feather edging, neatly cut the repair boundary with a concrete saw to a depth of 10 mm, and fully expose all corroded steel including the rear of the bar.
    2. Treat reinforcement. Clean reinforcing steel mechanically, paying attention to the rear of the bar to remove all corrosion products. Immediately coat the cleaned steel with one coat of Lavazinc EP or Lavafer.
    3. Saturate or prime. Soak the substrate with water and allow excess to evaporate or use a sponge to reach a saturated surface dry (SSD) condition. If application must be done in a short period, apply a Megabond SBR slurry bonding coat instead.
    4. Mix. Pour 3.0-3.25 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 for 3-5 minutes until homogeneous and lump free; always add powder to water and do not add extra water.
    5. Apply. Apply manually with a trowel or spatula to the SSD surface: 10 mm up to 50 mm on vertical surfaces and up to 100 mm per layer on horizontal surfaces. For a second vertical layer, apply the first with proper pushing and roughen it to improve bond.
    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.
