Mirror Coat is a high viscosity perfectly clear epoxy resin for coating bartops or casting jewelry or other parts. We have a detailed application guide for using Mirror Coat as well as a video in the additional information tab.
Mirror Coat features an easy to use 2:1 mix ratio.
To estimate usage you can calculate that it will take approximately 3 fluid ounces per square foot to get a thickness of .040" or 1 mm. For example, if i had a table that was 4'x4' and I wanted a 1/8" thick coating (0.125 or about 3mm), I would need a gallon and a half kit of Mirror Coat.
