Safety Data

Application Instructions

  • Substrate preparation:
    Mechanically abrade concrete surface to completely remove debris and loose particles. Wet the surface until complete saturation is achieved and allow standing water to either evaporate or be absorbed into the substrate. Alternatively, remove standing water using a sponge.

    Mix the grout either by hand or in a concrete mixer, adding 12-14 % of water (3-3.5 litres per 25 kg bag). Mix until completely lump-free, ensuring that a homogenous mix is achieved.

    Apply the grout by means of trowel or spatula, or alternatively pouring the grout onto the concrete substrate. Finish the surface to the required roughness grade. In case a bonding agent is required, it is recommended to consult to our Technical department.

    Once the grout is installed, surfaces must be kept damp for at least 10-12 hours, in order to prevent superficial dehydration of the cement.
