Find the corresponding mix ratio scale on the mixing cup. It's printed forward and backward because some guys like to look through the outside of the cup as they pour the paint. Notice there are three columns. Some paint formulas have a third component, possibly a reducer or a custom effect like a candy or pearl, in addition to the paint base and activator. If that were the case, the mix ratio may read 8:1:1, that is eight parts paint, one part activator, and one part thinner. In our case, though, we only have to mix two components to an 8:1 ratio, so we can ignore the third column.
