SR84 The effect of coatings on wood composite siding performance (2007)

This project was set up to investigate the effects of different coating types on the performance of hardboard sidings. Problems experienced in the 1980s with a New Zealand-produced product indicated that moisture entry was a key factor in the deterioration of these products.

Coatings play an important role in controlling the uptake and release of moisture in wood- based materials. With the introduction of imported hardboard cladding materials into the New Zealand market, further information on the effectiveness of different coating types was felt necessary.
