Hi Patrick,

Marine ply is usually supplied untreated. In this case it was lacquered on site with a satin varnish, in other cases we get it spray lacquered which gives it a harder finish. Either way its better to finish it after cutting the boards to size as you also need to seal the sides/ cut edges.

Hope this helps,

Ana

Thank you so much for your speedy response and answer. Can you recommend anywhere in London to get it spray lacquered? Many thanks.
