Predicting weather resistance of Recoated Outdoor Wood by Near Infrared Diffuse Reflectance Spectroscopy
2025 - IRG/WP 25-20757
Wood exposed to the outdoors causes slow degradation. One wood treatment to retain this degradation is paints and stains, and recoating is essential process for these coated wood products to achieve a long service life. We investigated that possibility of using near infrared spectroscopy to estimate repair condition and weather resistance of recoated outdoor wood. The specimens used for recoating ...

Diffuse cavity formation in soft rot of pine
1992 - IRG/WP 92-1541
A new type of soft rot of southern pine longitudinal tracheids is described. In this type, soft rot cavities form by diffuse degradation of the S2 cell wall layer by hyphae growing within the cell wall. Erosion is diffuse and irregular as opposed to the restricted, periodic erosion typical of type 1 soft rot cavity formation. Proboscis hyphae remain small (diameter 0.6 to 0.8 µm) and rapidly auto...

Colour change monitoring of photodegradation in Scots pine (Pinus sylvestris) – a short term focus
2009 - IRG/WP 09-40442
Colour change monitoring of photodegradation is a quick and easy method for monitoring rates of photodegradation in timber. A study was undertaken to compare this technique to other monitoring methods, including microtensile strength changes and weight loss. Colour changes due to accelerated sunlight exposure were monitored using a Datacolor check spectrophotometer and compared with a set of contr...
