Measuring the elasticity
of a varnish.
The drop of
the steel ball.
It is not up to the varnish of a wooden floor to avoid the small dents and signs of passing time that come from concentrated weights (high heels, the feet of heavy furniture) or falling objects. Wood is, by its very nature, prone to these small marks, parquet floors are meant to be walked on, things fall, and thus it is normal for them to bear the signs of aging. More often than not, these marks give the floor character, even a more interesting personality. It is the job of a good varnish to continue to do its job as protector even in the face of the hazards that present themselves.
Just like human skin, it too has to adapt itself to warping and handle it with elasticity, without getting hurt. That is, within certain limits. This to guarantee the fact that the wood can continue to be protected and not exposed to direct contact with external agents in order to keep its good looks intact. The elasticity levels of wooden floor varnish can be measured by a test that involves dropping a 42.8 mm diameter steel ball weighing 324 grams from increasing heights.
The height at which the first breakage occurs along the edge of the print it leaves determines how elastic it is. All of Listone Giordano varnishes achieve an extraordinarily high balance between elasticity and hardness, the main parameters that ensure the best resistance to being walked on.
