| Résumé : |
Cost-effective protection for the wood substrate is the foundation for ensuring the successful performance of exterior wood components. However, notwithstanding the considerable research and development efforts in the coatings industries during the last two decades, the fundamental problems of protecting the wood substrate against surface weathering and water entry remain as challenging as ever. This paper will focus on two main issues: water entry into wood and the performance of maintenance paint systems. The benefits of end-grain sealing will be reviewed, and results of recent Building Research Establishment (BRE) work into the relationship between coating permeability and moisture content in the wood will be presented. It will be argued that most modern coatings fail to control adequately moisture content fluctuations in the surface layers of the wood, and that this is detrimental for the long-term performance of the wood and coating alike. The need for ‘robust’ maintenance coatings possessing improved tolerance to imperfect surfaces and for quality assurance for wood coatings will also be discussed. |
