  1. Surface preparation

    ▪ Natural stone / slates / terracotta tiles must be firmly in place
    ▪ The joints must be free of dust, excess adhesive and loose material
    ▪ Joints should be moistened (not wet) prior to the application of the grout
    ▪ Quality of the grout will depend on the cleanness of the joint

  2. Mixing

    Mixing ratio: 4 lts (+/- 0.5lts) water per 20 kg bag
    ▪ Gradually add the powder into the required water quantity while mixing to avoid lumps forming
    ▪ Mix thoroughly to a creamy consistency
    ▪ Allow mix to gel for 5 min and then remix before use

  3. Application

    ▪ Using an appropriate tool (trowel and/or rubber float), apply MEP®. JOINT RUSTIC
    ▪ Completely fill the joints leaving no voids
    ▪ Excess grout should be removed immediately using a damp sponge
    ▪ When the grout has become firm in the joints (will depend on temperatures) the tiles should be cleaned with a clean damp sponge until all residues is removed

  4. Allowance for movement (where applicable)

    Flexible joints should be incorporated to allow for slight movements due to changes in temperature, humidity etc. as indicated by DTU 52.2:
    ▪ Where the tiling meets other materials (e.g. floor perimeters)
    ▪ Along all internal corners – vertically and horizontally
    ▪ Over existing movement joints or changes in background material
    ▪ Dividing large tiled areas into bays

  5. LIMITATION

    Do not use for:
    ▪ Areas subject to chemical agents: use MEP®. JOINT EPOXY
    ▪ Areas subjected to high-pressure cleaning: use MEP®. JOINT EPOXY
    ▪ Areas subjected to heavy duty traffic: use MEP®. JOINT EPOXY

  6. RECOMMANDATIONS

    ▪ Do not add water to the mixture being set
    ▪ Do not apply in wet weather, or in temperatures below 5ºC or over 35ºC
    ▪ Should the mortar stiffen up then discard the product and mix a fresh batch
    ▪ An excess in mixing ratio and a poor preparation of the joints leads to a shading of the grout

  7. PRACTICAL INFORMATIONS

    ▪ Packaging: 20kg 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
