Is varnish good for decking?
A varnish with non-slip properties, such as Blackfriar Anti-Slip Deck Coating, is ideal for decking as it provides a firm footing during wet weather and over winter when ice may form. Note that the build up of moss, mould, wet leaves, etc, will impair or even cancel the anti-slip properties. Varnish cures to form a hardened layer on top of decking to protect it from damage caused by UV light, exposure to weather, and foot traffic. It allows the natural beauty of the wood grain to show whilst being protected, as opposed to paints that cover the grain completely.
Can you use yacht varnish on decking?
No, we do not recommend this use for yacht varnish on decking. Yacht varnish doesn't provide anti-slip protection like a decking varnish does.
Is polyurethane better than varnish?
Polyurethane is better suited for interior and indoor applications as it lacks UV protection that exterior varnishes have. UV light from sun exposure turns natural woods grey and can cause splitting and drying out of the surface without protection.
Can I varnish over old varnish?
We don't recommend it. The chemical makeup of the two varnishes may not be compatible and affect adhesion, and the existing "varnish" may well be an oil. You may not benefit from the protective qualities of a varnish if it cannot adhere and harden properly - always test a small and inconspicuous area before full application.
