EXTERIOR WOOD FINISHES: PERFORMANCE TESTING BY ACCELERATED NATURAL WEATHERING

In recent years there have been important developments in paints for timber, with the introduction of British Standard performance specifications for wood primers, and of purpose designed finishes for exterior use. The latter typically involve the total elimination of the primer and undercoat from the system with the film being established by a coat-on-coat application of a low sheen product, although others comprise a system of primer and two gloss coats formulated to maintain flexibility. The work reported here involved the testing by accelerated natural weathering of a range of paints and exterior wood stains to enable their performance to be compared and assessed. In terms of appearance, amount of flaking, retention of adhesion strength and measured colour change, the paints were generally superior to the stains, although the performance of some stains equalled that of the best paints.
