MEP®. REP SOL is a fibre-reinforced, high strength mortar for the repair of concrete, to both horizontal and vertical surfaces

USES

• Repair of voids and honeycombed areas
• damages in concrete elements
• damages in corners and edges
• peelings concrete
• floor repairs

MEP®. REP SOL is suitable for the repairs in permanent contact with water

FEATURES AND BENEFITS

Faster strength development than ordinary sand-cement mortar
• Polymer modified to provide a strong bond to concrete
• Suitable for use in dry and wet conditions
• Resistant to foot and vehicular traffic

  1. Surface preparation:

    • The substrate must be firm and resistant, clean, free of any loose particles, oils, grease, dust, paint
    • All affected and brittle concrete must be removed until a healthy and structurally strong concrete is found
    • All edges to be repaired must be square cut to a minimum of 10 mm deep, perpendicular to the surface, followed by the removal of all unsound material
    • Expose all corroded reinforcing steel and remove the rust from the structures. Clean with a wire brush, needle pistols or sand blast to grade SA2 according to ISO 8501-1 / ISO 12944-4
    • Pre-wetted up to saturation point (with no free water) prior to application - at least 12 hours before

  2. Bonding:

    • Use a bonding slurry made of MEP®. REP SOL mixed with duralatex for non-structural applications
    • Use epidermix 344 wet to dry epoxy for structural applications where the bond strength must be equal or greater than the parent material

  3. Mixing

    Mixing ratio: 4.5 lts (+/- 0.5lts) water per 25 kg bag
    ▪ Gradually add the powder into the required water quantity while mixing to avoid lumps forming
    ▪ Mix thoroughly using a low speed mechanical mixer to a creamy consistency
    ▪ Allow mix to gel for 2-3 min and then remix before use
    NB: Never add more water to the mix. Should the mortar stiffen up due to delays in application then discard the product and mix a fresh batch

  4. Application:

    • Apply MEP®. REP SOL to the tacky bonding product (duralatex slurry or Epidermix 344)
    • Compact into position and finish as required (float or smooth)
    • For vertical repairs, carefully apply the mortar into position in layers of about 10 – 20 mm, and allow to reach initial set before applying the next layers
    • For small floor repairs, square cut to a minimum of 10 mm deep perpendicular to the surface and apply a bonding slurry made of duralatex mixed with MEP.REP Sol. On the still wet slurry, compress the repair mortar and level to the required high
    • For large floor repairs, apply a bonding slurry made of duralatex mixed with MEP.REP Sol. On the still wet slurry, compress the repair mortar and level to the required high
    • For trafficable floor repairs, MEP.PRIM Epoxy should be applied 24h prior application of MEP.REP Sol

  5. Curing

    Good curing is essential. After the finishing operation, spray with water and cover
    Alternatively, spray-apply a proprietary curing membrane with a minimum efficiency of 50%

  6. RECOMMENDATIONS

    • Do not apply in wet weather, or in temperatures below 5ºC or over 35ºC
    • Wind reduces cement open time and leads to reduced adherence
    • Do not add cement, sand or other substances that may affect the properties of the mortar
    • Use the specified water for mixing. A larger amount of water reduces the mechanical resistance and increases cracking and shrinkage

  7. PRACTICAL INFORMATION

    • Packaging: 25kg triple-ply paper bags.
    • Handling and storage: 6 months if kept in a dry cool place in the original packaging
    • In more extreme conditions this period might be shortened
