  • Ideal for use on terraces and balconies.
  • Can be applied on wall, floor, and underfloor heating systems.
  • Suitable for both interior and exterior use.

Treatment

Suitable Substrates

  • The product is suitable for grouting honed, polished, or split natural stone surfaces such as marble, Solnhofen slabs, and granite. Conduct a test grouting for porous, non-sealed, highly stain-sensitive surfaces, or unknown stone types.

Mixing / Preparation

  • Add the recommended amount of water into a clean container, then gradually mix in the dry mortar. Use clean tap water and mix until homogeneous, then let it rest briefly before stirring again. Always mix with the same amount of water to prevent color differences. Do not mix with other products.

Application

  • Apply the grout diagonally to the joints using a rubber or foam grout board, ensuring it's level. After setting (finger test), remove excess grout with a damp sponge without washing out the joints. Any remaining haze can be removed once dry.

Processing Time

  • Approximately 30 minutes. Do not re-mix set mortar.

Drying / Curing

  • Protect the grout from quick drying, frost, drafts, and extreme weather by covering it with plastic if needed.
