    Field of application

    • For use indoors and outdoors
    • for dimensionally stable elements
    • For professional users only
    • For sealing narrow torn, cut and mitre joints in woodworking and window construction
    • For use by professionals


    • Very high solid content: Low shrinkage & early resistance against dry cracks
    • Easy to apply
    • Can be overcoated with conventional water-based varnish and stain systems
    • Dries to form a transparent film
    • Preparation
      • Substrate requirements

        Joint sides must be clean, dry, free from grease and capable of bearing a load.

        Use on the primer or intermediate coat.

      • Preparations

        Preliminary trials are generally advised in order to optimise the workflow and waiting times.

    • Application
      • Temperature of the material, air and substrate: from min. +15 °C to max. +30 °C
      • Gun for sealing compounds
      • Cut off tip at an angle according to the width of the joint and inject, filling the joint completely.

        Apply the material with sufficient pressure to the sides of the joint, then smoothen with a moist spatula.

        Avoid applying an excess of the fresh compound.

        Use a suitable tool or finger cot to level off the filler.

    • Application instructions

    • Usage
      • Application rate per 2 x 2 mm / 5ml/m joint section
      • Approx. 5 ml/running metre for a 2 x 2 mm joint cross-section

    • General information
      • Glued joints must be produced properly until glue is discharged over the entire surface area in accordance with the glue manufacturer's instructions.

        When applying a subsequent coating on Induline AF-920, the layer must not be made too thick. The layer thicknesses specified in VFF Leaflet HO.03 must be observed.

        On large-pored wood, we recommend sealing with AF-920 after applying the intermediate coating.

        Current regulations and legal requirements must be taken into account and deviations from these must be agreed separately.

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