    Lavarep 2P two component polymer modified cementitious repair mortar by MATEX

    Lavarep 2p

    Two Component Polymer Modified Cementitious Repair Mortar

    LAVAREP 2P is a two-component, polymer-modified cementitious mortar designed for high-performance structural concrete repair. Component A (powder) includes hydraulic binders, silica, graded aggregates, fibers, and additives, while Component B (liquid) is a synthetic polymer latex. Together, they form a non-shrink, highly durable mortar with excellent flexibility and impact resistance. LAVAREP 2P offers strong adhesion to concrete substrates and forms a low-permeability, smooth surface that resists atmospheric gases, frost-thaw cycles, chlorides, salts, and chemical attack. Its ease of application and long-lasting performance make it ideal for demanding repair environments requiring robust mechanical and protective properties.

    How to Apply Lavarep 2p

    Lavarep 2P is applied by trowel or spatula to a prepared, saturated surface dry (SSD) concrete substrate.

    1. Prepare the surface. All surfaces must be sound, clean, compact and free from dust, grease and inconsistent parts. Expose the fine aggregates of the concrete by brushing with a steel brush or light blasting.
    2. Clean and saturate. Clean the prepared surface with blown compressed air, then saturate it thoroughly with clean water. Allow excess water to evaporate or use a sponge to reach a saturated surface dry (SSD) condition; application over dry concrete without saturation will result in failure of the repair.
    3. Mix. Pour Component B (liquid) into a suitable container, add Component A (powder) and mix with a spiral paddle on a slow-speed heavy-duty mixer for 2-3 minutes until homogeneous and lump free. Rest the mix for 3 minutes and remix before use; do not add extra water.
    4. Apply. Apply manually with a trowel or spatula to the SSD surface, up to a maximum of 6 mm per coat. If more thickness is required, keep the first layer rough and apply a second layer at a 4 to 6 hour interval.
    5. Finish. For pinholes or fine honeycombs use a steel trowel. Once the applied mix starts to partially set, trowel the whole surface to obtain a smooth finish.
    6. Cure. Avoid rapid evaporation of the applied mortar. Cure the applied coat for two days using clean water or a coat of a recommended MATEX curing agent such as Cemcure.
    7. Clean tools. Clean tools with water before the product hardens. Hardened material can only be removed mechanically.

    Frequently Asked Questions

    What is the maximum thickness per coat for Lavarep 2P?

    Lavarep 2P is applied up to a maximum of 6 mm per coat. If more thickness is needed, keep the first layer rough and apply a second layer after 4 to 6 hours.

    What is the coverage of Lavarep 2P?

    Lavarep 2P covers approximately 1.62 kg per square meter at 1 mm thickness. Coverage is approximate and subject to site conditions.

    What temperature range can Lavarep 2P be applied in?

    The application temperature is from +5°C to +35°C. Do not apply when the surface temperature is below 5°C or above 35°C.

    How long is Lavarep 2P workable after mixing?

    Workability is 40-45 minutes at 25°C. Mix only as much material as can be applied within the product’s open time.

    How is Lavarep 2P packed and how long is its shelf life?

    It is supplied as a 30.0 kg kit of 23 kg Component A (powder) and 7.0 kg Component B (liquid). It can be used within 12 months of production if stored unopened in original packing in dry conditions away from direct sunlight and high humidity.
