Wood Coatings are basically a kind of material to be applied on wooden surfaces to protect the wood from different natural and manmade factors. Wood coatings make wood easier to clean and keep it sanitized. It also helps in sealing pores that can be breeding grounds for bacteria.
The test method provided in BS EN 927‑3 gives a means of evaluating the performance of a wood coating system during outdoor exposure. It forms the basis for the performance specification in accordance with EN 927-2. It also facilitates the comparison of coating systems performance on different substrates including the wood species, or other wood modifications.
With BS EN 927‑3 helping in performance evaluation, the process of protecting outdoor swan wood can be made considerably easier for you and your organization.
