    Field of application

    • For use indoors and outdoors
    • Underwater areas
    • Natural stone
    • Joints subjected to especially high mechanical and chemical stresses
    • Areas that are permanently underwater
    • Food industry
    • Medical treatment rooms


    • No discolouration on natural stone
    • Highly resistant to mechanical and chemical stresses
    • Highly elastic
    • Preparation
      • Substrate requirements

        The sides of the joints must be dry to slightly damp, clean, free from grease and capable of bearing a load, and metals must be sound.


        Adhesive primer

        Natural stone - Silicone Primer P

        Joints subjected to high stresses - Silicone Primer P


        Underwater areas:

        Dry joint edges - Underwater Primer

        Slightly damp joining edges - Epoxy MT 100

    • Application
      • Gun for sealing compounds
      • Application temperature: min. -5 °C max. 35 °C
      • Application requirements

        Temperature of the material, air and substrate: from min. +5 °C to max. +35 °C

      • Cut off tip at an angle to match the joint width.

        Apply the material to the joint edges with sufficient pressure.

        Pull off using a smoothing agent and a suitable tool.

    • Application instructions
      • Take appropriate measures to protect adjacent building elements and materials that should not come into contact with the product.

        Joint dimensions depend on the loading stresses, the building material properties, and the permissible total deformation of the sealant.

        The applicable regulations and legal requirements must be observed.

        Can be removed with V 101 while wet.

        Once the material has cured, remove contamination mechanically and clean using Silicone Remover.

    • Working tools / cleaning
      • Gun for sealing compounds
      • Manual or compressed air gun, smoothing tool, adhesive tape

      • Clean with V 101 while wet.

    • Storage / shelf life
      • Shelf-life 12 months
      • Store frost-free and cool / protect for moisture / close containers
      • If stored unopened in its original container in a cool, dry place and protected against frost, the product will keep for at least 12 months.

    • Usage
      • Total application rate approx. 100 ml / cm² x m
      • 100 ml/running metre for a 1 cm² joint cross-section

      • Apply to a large enough trial area to determine the precise amount required.

    • General information
      • Deviations from applicable regulations must be agreed separately.

        The relevant test certificates must be observed when planning and carrying out work.

        Always set up a trial area/trial areas first.
