The stated values represent typical product characteristics and are not to be construed as binding product specifications.
Field of application
- For use on exterior wood
- Wood without ground contact
- Wood building elements with no dimensional stability: e.g. fences, framework, carports, planking
- Wood building elements with limited dimensional stability, e.g. folding shutters, matchboarding, summerhouses
- Dimensionally stable wood building elements (when used as a primer only): e.g. windows and doors
- Primer, intermediate and finishing coats
- Natural grey tones for exterior wood
- Even colour tone across areas exposed to weathering and areas sheltered from weathering
- 3 in 1: impregnation, priming and stain
- Protects wood from moisture and UV radiation
- Impregnation effect: saturates wood to protect against moisture
- Diffusion-open protective film: moisture can escape
- Water-repellent: wet surfaces dry quickly
- Reduces the risk of rot when used in conjunction with constructive wood protection measures
- Increased solids content provides protection against nesting wasps
- Coating is protected against mould, algae and blue stain
- Subsequent treatment without sanding
Dimensionally stable wood building elements: wood moisture content 11-15%
Wood building elements with limited or no dimensional stability: wood moisture content max. 18%
Completely remove old coatings (e.g. paints or medium-build stains), bark, bast and dirt.
Remove loose and torn knots as well as resin that bleeds and clean with a suitable product (e.g. thinner & brush cleaner).
Smooth, planed wood surfaces should be sanded and dusted before the coating is applied to ensure better absorption.
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
Private users: Application by brush.
Professional operations: Application by brush, dipping, flow coating; spraying only in closed facilities.
Apply in the direction of the grain.
Apply a second coat once the first has dried.
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.
If the surface is overcoated with other products it is recommended to test the adhesion to the substrate.
Rainfall may cause water soluble substances to bleed from wood that is rich in such substances, e.g. oak, red cedar, afzelia, redwood, etc. This may lead to the discolouration of light-coloured masonry or render.
Pre-testing is recommended also on other woods.
Cut end-grain surfaces at the bottom to create a water-drip edge.
Apply two subsequent coats of end-grain wood preservative to end-grain wood and cut surfaces in order to protect them against moisture.
Each layer of medium-build stain results in a more intense colour and a glossier finish.
Approx. 12 hours at 20 °C and 65% relative humidity.
Low temperatures, poor ventilation and high humidity delay drying.
Even once the coating is sufficiently dry for handling, less volatile solvents may cause surface to feel clammy to the touch over several days!
This property does not constitute a flaw!
The evaporation of these solvents can be accelerated by the ensuring the highest possible air exchange.
Ready to use
Working tools / cleaning
Brush with natural bristles, flat brush
Clean tools immediately after use with thinner and brush cleaner.
Ensure that any residue from cleaning is disposed of correctly.
Storage / shelf life
At least 36 months in unopened, original containers stored cool, dry and protected from frost.
Approx. 100 ml/m² per coat, at least 2 coats required
Planed or very thick woods are less absorbent and may require a third coat
On planed larch and softwoods with a high resin content, the coating may have reduced adhesion and resistance to weathering. This is especially the case on horizontal year rings, knots and areas of winter growth that are high in resin. Maintenance and renovation must be carried out more frequently on these surfaces. The only remedy for this is pre-weathering or very coarse sanding (P80). If these wood types are rough-sawn, considerably longer maintenance and renovation intervals are to be expected.
Larger quantities of leftover product should be disposed of in the original containers in accordance with the applicable regulations. Completely empty, clean containers should be recycled. Do not dispose of together with household waste. Do not allow to enter the sewage system. Do not empty into drains.
