What Is The Difference Between Spar Urethane And Varnish?
If the woodwork is your expertise or you are working on a project on an individual basis then you can always use a varnish for providing a final finishing. Woodworks such as exterior doors or small artifacts, ships or boats, etc require a lot of perfection to stay intact and protected and also, of course, a perfectly beautiful finishing. This is the reason why some workers use varnish which enhances the natural color of finished wood and provides you with completely new material.
What is spar varnish and why is it used?
Spar varnish is a wood finishing varnish. It was originally used for coating the spars of sailing ships. But it is now used for the finishing of various other word products.
Varnish has many uses apart from providing a finishing. It protects the wood from harmful ultraviolet rays and it also protects the wood. Apart from that, it protects the wood from water that is why it was originally used on wooden boats, etc. Varnish provides wood with a rustic outlook to give an authentic look.
What is spar urethane and why is it used?
Spar urethane is actually a spar varnish that uses plastic urethane as its resin. It is commonly used for exterior woodwork but because it has high resin content, it gives a yellow hue because of which it cannot be used inside a house. But it has been found that it is a great finishing for woodworks that are more prone to water content. Such as bar tops, etc.
One might think that both spar varnish and spar urethane are similar products or that there are no differences. But there are some slight differences between the two.
What is the difference between these two?
While both spar varnish and spar urethane are similar products with similar consistency, one difference that sets the two aside is the fact that spar urethane takes longer than a spar varnish to set. A conventional varnish sets faster in comparison to spar varnish.
Another difference includes that spar urethane has high resin contents for which it cannot be used inside a house or for interior woodworks as it creates yellow hues that are harmful but a spar varnish can be used for interior woodworks too.
Another difference includes that spar urethane is synthetic in nature and can either be used as an oil base or water base.
Spar urethane is more long lasting especially when the wood product is a boat, that is, it does not require a frequent application but it may cost a lot in comparison to spar varnish which requires frequent application and is inexpensive.
Studying spar varnish vs spar urethane – the differences we come to the conclusion that both these components are used for similar reasons. While the latter is more concentrated and is limited because of the same, the former is more conventional in nature and can be used more extensively. But since they both are perfect in some way or the other, the usage totally depends on the requirement and circumstances!
