    • for not dimensionally stable elements
    • For use on interior and exterior wood
    • Dimensionally stable wood building elements: e.g. windows and doors

    • Preparation
      • Substrate requirements

        Dimensionally stable wood building elements: wood moisture content 11-15%

        Wood building elements with limited or no dimensional stability: wood moisture content max. 18%

      • Preparations

        Thoroughly remove any dirt, grease and non-adhering old coatings.

        Using a brass brush, thoroughly clean greyed and weathered wood surfaces to ensure optimum adhesion.

        Remove loose and torn knots as well as resin that bleeds and clean with a suitable product (e.g. V 101 thinner, thinner & brush cleaner).

        Pre-treat wood in outdoor areas which requires protection against rot and blue stain with Wood Protection Primer.*

        Round off sharp edges.

        Observe BFS Code of Practice No. 18 "Coatings on Wood and Wooden Working Materials in Outdoor Areas".

    • Application
      • Brush
      • Stir before use
      • Application requirements

        Temperature of the material, air and substrate: from min. +5 °C to max. +30 °C

      • Stir well.

        Apply by brush.

        Apply in the direction of the grain.

        After drying, apply the intermediate and final coats of LT Stain UV.

        Seal opened containers well and use contents as soon as possible.

    • Application instructions
      • Drying time: can be worked over after 4 h
      • Check colour and compatibility with the substrate by applying a trial coat.

        When renovating windows and exterior doors, we recommend an intermediate sanding step using sandpaper (P180) or a fine sanding sponge prior to further coating.

      • Drying

        Can be overcoated: after approx. 4 hours

        Practice values at +20 °C and 65% relative humidity.

        Low temperatures, poor ventilation and high humidity delay drying.

      • Thinning
