The Mixing Process of Interior and Exterior Paints

First, take two buckets in which you can keep five gallons of paint on each. Now take one bucket and filled the pail 2½ of the bucket with one paint with a flat texture and another 2½ with semi-gloss texture paint. Now put the mixture on the bucket and then again pour the paint on the old bucket. In this way, try to mix the two different paints.
