Floor Gloss Readings

Early specifications called out for gloss readings in the 50 or 60 range.

Floor gloss readings.

Gloss readings came about because of the big box retailers and the architects as a way to validate the finish on a finished concrete floor. Gloss is determined by projecting a beam of light at a fixed intensity and angle onto a surface and measuring the amount of reflected light at an equal but opposite angle. Gloss values express the degree of reflection when light hits the concrete floor surface and range from 20 to 30 low gloss to 70 to 80 high gloss. Gloss the shine or gloss level of a floor which increases with each coat of finish you apply.

Today specifications for polished concrete are now including specified gloss readings determined using gloss meters see table. A glossmeter also gloss meter is an instrument which is used to measure specular reflection gloss of a surface. It is one thing to check a homogenous surface such as glass but measuring the gloss. Standard mode to take an individual spot measurement auto repeat mode which automatically takes individual gloss readings at a user definable rate and scan mode for measuring gloss on large surfaces providing the average highest and lowest readings.

However when checking the gloss of a surface physical properties of the surface uniformity surface irregularities must be taken into account. There is a tool used to measure gloss and it s called a gloss meter. There are a number of different geometries available for gloss measurement each being dependent on the type. Gloss readings are achieved by measuring the reflective index of light.
