Gloss Meter for determining the gloss level of polished concrete…
A Gloss Meter will accurately assess the degree of shine of your polished concrete floor. Specifications for polished concrete are now including specified gloss readings, determined using these meters. Gloss values express the degree of reflection when light hits the concrete floor surface. Values range from 20 to 30 (low gloss) to 70 to 80 (high gloss). A gloss value of around 30 will generally produce a low-satin sheen while a value of 80 will produce a very high shine, especially after high-speed burnishing.
|Level||Grit||Sheen Level||Gloss Reading||Appearance|
|1||100||Dull||N/A||Floor has little, if any, reflectivity.|
|2||400||Low Sheen||40-50||From a distance, floor will start to reflect images from the side. Floor has a whitish or cloudy appearance.|
|3||800||Shiny but slightly cloudy||50-60||At a distance of 10 to 15 mtrs, the floor reflects from side to side. Floor starts to shine, but has a slightly fuzzy appearance.|
|4||1500-3000||High sheen with clarity||60-80||Looking straight down on the floor, it clearly reflects overhead and side lighting. The floor is very shiny and looks wet from a distance.|
