Exterior wood preservation

Long-lasting and naturally beautiful wood facades in no time at all

The appearance and durability of wood facades depend on a number of factors: the type of wood, the quality of wood, the pretreatment of the wood surface and the subsequent surface treatment.

The water-thinnable, thin-film transparent wood finish, Lignovit Platin, enables spectacular, metallically shimmering colour effects and features outstanding weather resistance and an even decomposition when exposed to the weather.
Pullex Platin for wood outdoors enables spectacular, metallically shimmering colour effects. The open-pored product is characterised by very good protection against water, high durability and even decomposition when exposed to the weather.
Brushing fully brings out the grain. Combined with the silvery pigments of Pullex Silverwood, the result is exciting light effects and interesting facade designs.

TYPES OF WOOD FOR THE FACADE
All domestic types of softwood are basically suitable for constructing facades; in Germany and Austria, spruce wood is used above all, sometimes also larch. 

THE TYPE OF PRETREATMENT INFLUENCES THE SERVICE LIFE  

The type of pretreatment plays an important role for the service life of the subsequent paintwork applied. A dry, resin-free and absorbent substrate is ideal. This results in a very good in-depth effect of the impregnation (=transports the active substances into the wood), a very good anchor for the top coating and an homogeneous colour formation. 

  • Rough-sawn: rough-sawn wood generally has a very high absorption capacity. This means the coating is brilliantly absorbed. It is important to clean loose particles of wood off the rough-sawn surface before being coated. (See sample in the picture gallery)

  • Brushed surface: brushing in the direction of the grain removes soft young wood from the surface, thereby achieving a textured surface. The wood is given a modern, rustic look. (See sample in the picture gallery)

THE COATING PRESERVES THE NATURAL QUALITY OF WOOD FACADES

Wood facades are coated as a rule to give them better protection against the weather and environmental factors, blue stain, fungi and insects. At the same time, this also prevents uneven greying and unwanted colour differences.

An even, (silvery) premature greying, the so-called patina effect, is increasingly used by architects as a design element. This effect can be achieved quite easily with the ADLER products Pullex SilverwoodPullex Platin or Lignovit Platin. These products guarantee maintenance-free and lasting protection without impairing the natural quality of the wood facade.

ADLER RECOMMENDS THE FOLLOWING COMBINATIONS FOR A MAINTENANCE-FREE AND EVENLY GREYED FACADE:

  • Spruce/rough-sawn: spruce is good to work with and absorbs surface treatments very well. The drying process is fast and without difficulties. For the subsequent coating, you are best off using Lignovit Platin, Pullex Silverwood or Pullex Platin. (See sample in the picture gallery)
     
  • Spruce/brushed: : brushing fully brings out the grain. Combined with the silvery pigments of Pullex Silverwood or Lignovit Platin, the result is exciting light effects and interesting facade designs. (See sample in the picture gallery)
