Use in cases where brickwork needs significant reinforcement (e.g. old brick- and stone-walls, etc.). In cases of dislocated masonry combined with metal mesh. Also use as high-strength mortar in structures with 3D grating, before applying the plaster, as well as on substrates of bricks, cement blocks, aerated concrete (e.g. YTONG), concrete, stone, etc.

  • Make sure that the surface is clean and free of loose material.
  • To prepare, simply add water.
  • For better results, it is recommended to use a sprayed concrete pump (Gunite pump) or other special pump.
  • Apply in successive coats up to 2 – 2.5 cm thick per coat.
  • The wet mortar must be distributed uniformly over the wall and must be fixed with special laths.
  • In case of high temperatures during application, the wet mortar must be protected against quick drying and remain wet.
  • The wet incident material that piles up on the floor must not be used again.
  • Continue with the subsequent coats of MARMOLINE plaster (SV 2, SV 3, SV 100, SV 010), once the previous coat of GN 30 is well dry and in any case after 20 – 30 days, depending on the season.
