Conclusions

Provided that the joinery is well constructed and the coating application is thoroughly undertaken it is possible to use a multiple, water-based coating system with a maintenance-free period of minimum 5 years.

In this respect the multiple coating system gives adequate durability to the Scandinavian system used presently with double vacuum impregnation + 2 spray coats.

The key factors for this system are:
  1. 1.

    Water absorption has to be prevented

     
  2. 2.

    Microbial infection on the coating surface, in the wood coating interface and in the wood itself has to be prevented.

     
  3. 3.

    The wood has to be protected from excessive moisture uptake and UV-light.

     
  4. 4.

    The treatment has to reduce rapid moisture fluctuation or dimensional changes.

     
  5. 5.

    The film should be essentially free from defects like air-pockets, pores and poor wetting at the edges.
