The stated values represent typical product characteristics and are not to be construed as binding product specifications.
Field of application
- For use on interior and exterior wood
- Dimensionally stable wood building elements: e.g. windows and doors
- Wood building elements with limited dimensional stability, e.g. folding shutters, matchboarding, summerhouses
- Wood building elements with no dimensional stability: e.g. fences, framework, carports, planking
- Maintenance and levelling of greyed and spotted wood surfaces
- Weatherproof and moisture-regulating
- Quick drying
- Good coverage with just one coat
- Very good adhesion to the substrate
Dimensionally stable wood building elements: wood moisture content 11-15%
Wood building elements with limited or no dimensional stability: wood moisture content max. 18%
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. thinner & brush cleaner).
Pre-treat exterior wood which requires protection against rot and blue stain with Wood Protection Primer.* (*Use biocides safely. Always read the label and product information before use.)
Round off sharp edges.
Observe BFS Code of Practice No. 18 "Coatings on Wood and Wooden Working Materials in Outdoor Areas".
Temperature of the material, air and substrate: from min. +5 °C to max. +30 °C
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.
Check colour, adhesion and compatibility with the substrate by setting up a trial area.
When renovating windows and exterior doors, we recommend an intermediate sanding step using sandpaper (P180) or a fine sanding sponge prior to further coating.
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.
