    The stated values represent typical product characteristics and are not to be construed as binding product specifications.

    Field of application

    • Repair, renovation and restoration of damp walls and floors that are susceptible to mould infestation
    • Humidity regulation indoors
    • Improving the energy performance of exterior walls


    • Diffusion open and capillary active
    • High proportion of capillary condensation capable pore volume
    • Thermally insulating
    • Two-layer application thickness up to 50 mm
    • High sulphate resistance and low active alkali content (SR/NA)
    • Preparation
      • Substrate requirements

        Clean, dust-free and capable of supporting a load.

      • Preparations

        Pre-wet the substrate so that it is slightly moist.

        Apply SP Prep (Preparatory Mortar) in nodules as a fully opaque bonding layer.

    • Application
      • Apply product using a suitable tool or machine.

        Level off surface with a long float.

        Finish the surface once set.

        If applying an additional coating, use a grated scraper to roughen the surface once it is sufficiently dry.

        Waiting time before application of further layers: 3 days.



        Single layer thickness up to 20 mm.



        Layer thickness per coat 10 - 20 mm.

        Layer thickness up to 30 mm wet-on -wet.

        Layer thickness 30-50 mm, apply second layer once the first is sufficiently dry (approx. 12-24 hours).

        Roughen the first layer with a render comb.


    • Application instructions
      • Once it has hardened, mortar must not be made workable again by adding either water or more wet mortar.

        On critical substrates (highly uneven and/or fissured) we recommend incorporating the reinforcement fabric in the upper third of the restoration render.

        Apply additional diagonal reinforcement to the edges of building openings.

        Protect wet mortar surfaces against frost, rain and drying out too quickly for at least 4 days.

        Hairline/shrinkage cracks are safe and are not cause for complaint as they do not impair the properties of the mortar.

        To ensure that the renovation is successful, the relevant drying conditions according to WTA Code of Practice 2-9-20/D must be met.

        Please contact Remmers Technical Service (phone +49 5432 83900) before applying with machine processing.
