| Summary: | Performance of wood preservatives or coatings as surface treatments products is closely
connected to different needs and requirements. This paper investigated the protective efficiency of
such products, on fir wood exposed outdoors for 7 years, in a modified L-joint test. The evaluation
refers to degradation as result of the combined action of the biotic and non-biotic factors, active in use
class 3. Two common non-destructive methods were used to evaluate the wood exposed outdoors:
visual assessment and microscopic evaluation. Rating of the exposed faces showed that untreated
control samples presented the most severe biological degradation and cracking. Surface bioprotection
minimised discolouration and was generally a beneficial treatment prior coating. The
surface treatments investigated in this paper generally delayed the degradation phenomena but could
not provide an efficient protection over a long exposure period. |
