Since the definition of spar is a pole that supports the sail of a ship or boat, the antonyms of spar are the antonyms of the synonyms of spar. Some synonyms are rod, rail, and varnish.
It's a very good marine quality varnish.
Yes, but why waste the varnish. - (it is meant for bare wood )
Yes, Spar varnish is a marine quality exterior varnish that can be used over many surfaces, however it does have an amber hue that will affect the color of whatever surface is being coated. If you're looking for a long-lasting crystal clear coating then a better choice would be a water-based polyurethane coating.
As in the stuff you put on your nails? Polish. Really, though, the British have it all wrong--nail "varnish" isn't varnish at all, it's nitrocellulose lacquer.
Nail varnish is the coloured polish, and that goes on first. The french polish is just a see-through layer that is a strengthener/hardener to make the coloured varnish last longer and that goes on top after you have applied 1 to 2 coats of the coloured nail polish.
Spar varnish can be used in this scenario, and would give a great shine to the deck. However, depending on the thickness of the layer of varnish applied, it could rapidly turn cloudy and destroy the look of the cedar. Consider a sealant instead.
I was wondering the same thing when I found your question. Well, with further research I found the answer is 'not recommended'. Although spar varnish is made for marine use, it never quite dries. It needs to remain a little soft to compensate for the woods flexing in heat and cold or it would crack, so it's not as hard as floor finish.
I would use an exterior polyurethane. It is going to hold up better and be more flexible than a varnish. Polyurethane has taken over the varnish market--it's hard to find any other kind. There is a "spar polyurethane," which is what you should use on the item in question.
The ester in a nail varnish is a good solvent that is used in nail polish removers because it dissolves the nail varnish and does not affect the nail.
No. The spar varnish acts as the sealer. Apply a thin coat and allow it to dry. Apply a second coat and allow it to dry. These two coats should have sealed the pores of the wood. Apply the third coat slightly thicker, so you get a nice even "wet look" to the wood.
Nail polish remover is usually diluted acetone. Varnish remover is usually either toluene or mineral spirits.
