The coverage for Yacht Varnish will depend on the nature of the substrate and the dry film thickness, so expect a coverage of approximately 10 - 12m² per litre per coat.
Yacht Varnish is designed to be used for external applications where it has to cope with UV light and the flexing of timber as it moves during the seasons. Therefore Yacht varnish contains UV inhibitors to prevent yellowing and remains slightly soft and flexible to cope with the expansion and contracting of timber during the seasons thereby preventing cracking, peeling or blistering. The Floor varnish is designed for internal use so is harder and more wear resistant than the Yacht Varnish.Yacht varnish is not suitable for high wear floor areas.
White spirit is the recommended thinner for Flag Yacht varnish and for the cleaning of tools after use.
No, if you apply yacht varnish too thickly and don't allow sufficient time for it to dry between coats you will end up with a soft spongy coating.
Flag Yacht Varnish is only suitable for applying above the waterline.
