Floor varnishes can be used on different types of wood, such as furniture, woodwork, and floors. They're designed to provide an even finish thanks to a spreading agent that allows the varnish to better settle on the surface.
To apply this type of varnish, it's recommended to use specific tools such as a roller with a thickness of 10mm, a synthetic bristle brush, or a spray gun with a 1.3-1.4mm needle. It's also possible to use two-component varnishes that offer increased resistance to abrasion and household chemical products. By using a quality varnish, you can expect it to last several years.
