Made of stainless steel with straight scraper fitted with 5 pairs of notches of increasing depth from 25µm to 4.06mm (1 to 160mils), the Elcometer 4260 NYPC Levelling Tester is used to determine a coating's ability to level before curing.

Once the drawdown has been made on a horizontal, firm surface, leave the coating to cure. Once the coating is dry, identify the thickness at which the pair of film stripes merge.
