        Treatment of wood:

        It is not possible to combat fungal attack (dry rot etc.) with the currently approved chemical wood preservatives. Fungal attacks are usually combated by removing the affected wood. Remove superficial mycelium, fungus growth and all infested parts of the wood at least 1 m beyond visible infestation in the longitudinal direction of the wood.
        Impregnate new wood and old wood that is not infested with Adolit Timber Construction B* or IG-10* for preventive protection against insects and fungus.


        Treatment of masonry work:

        Remove render at least 1.5 m beyond visible infestation, chase out joints at least 2 cm deep.

    • Application
      • Application temperature: min. 5 °C
      • Brush
      • Bore hole saturation
      • Application requirements

        Temperature of the material, air and substrate: min. +5 °C

      • Surface treatment method:

        Use a 10% solution for surface treatment.

        If infestation has penetrated into the wall, use borehole saturation or borehole pressure impregnation in addition.


        Borehole saturation:

        Creating boreholes: Offset in two rows, diameter 20-30 mm, spacing approx. 25 cm horizontal and approx. 15-20 cm vertical, inclination 30°-45°, borehole depth up to approx. 15 cm from end of wall.

        Reduce the spacing to 10 cm vertical and horizontal in the region of the beam end support.

        Fill the boreholes with the material solution several times depending on the suction capacity. Then, fill the boreholes with BSP 3.


        Borehole pressure impregnation:

        Creating boreholes: In a grid pattern, horizontally or with a slight downward inclination, spacing approx. 25 cm horizontal and approx. 20-30 cm vertical, borehole diameter 12-18 mm depending on the injectors used, borehole depth up to approx. 15 cm from end of wall.

        Use injectors (Ø 18 mm) with the large drive-in cap.

        Inject Adolit M Liquid as a 10-40% solution using a low-pressure method (3-4 bar) with suitable injection apparatus.

        After injection, fill the boreholes with BSP3.

    • Application instructions
      • Check colour, adhesion and compatibility with the substrate by setting up a trial area.

        To make sure that treatment is successful in the long term, it is important that
        the causes of the moisture - which in conjunction with a spore infection caused the infestation - are remedied. Observe DIN 68 800-4: (Wood preservation; Curative treatment of wood destroying fungi and insects), DIN 68 800-2: (Wood preservation; Preventive constructional measures in buildings) and DIN 68 800-3: (Wood preservation; Preventive chemical wood preservation). Also refer to the WTA Code of Practice 1-2-05 "True Dry Rot" issued by the Scientific Work Group for Monument and Building Preservation e.V., Munich.

        To protect against rising damp, place packers between the boreholes in the horizontal row of boreholes.
        Use the Kiesol waterproofing system after three to four weeks.
        Salt inhibitor is suitable for protection against masonry salts in the evaporation zone.

    • Working tools / cleaning
      • Brush
      • Bore hole saturation
      • Brush, injection packers, plastic injectors, injection pumps with attachments or K-surface sprayer with instantaneous stop valve, pressure hose and gripping head

      • Clean tools with water immediately after use.

        Ensure that any residue from cleaning is disposed of correctly.

    • Storage / shelf life
      • Store frost-free and cool / protect for moisture / close containers
      • Store in well-sealed, original containers, out of the reach of children and in a dry, cool, well-ventilated room which is protected from direct sunlight and frost. No smoking is permitted in storage areas.

    • Usage
      • Approx. 50 g / m² per layer applied
      • Approx. 3 kg / m² per layer applied
      • Surface treatment:
        50 g concentrate per m²
        Application concentration: 10% (500 g of ready-to-use solution)
        Borehole saturation and borehole pressure impregnation:
