Calculate the amount of epoxy resin you will need for your project.
An easy way to estimate the amount of epoxy resin needed for a tumbler is to do 1ml per ounce of cup size. For instance we will mix 20ml per 20oz Skinny Tumbler.
1ml per square inch
Measure both the Length and Width in inches. Length x Width = Square Inches
LARGE PROJECTS (Countertops, Tables, Bartops)
3oz per square foot
Measure both the Length and Width in feet. Length x Width = Square Feet
Mix at least 2 fluid ounces at a time to ensure your mixing ratio is correct.
