Pettit 9080 Easypoxy Satin Additive produces a semi-gloss to semi-flat finish when blended with any color Pettit Easypoxy paint. The semi-gloss to semi-flat finish is often desired for non-glare deck surfaces and interiors. There is no set ratio of Satin Additive to paint; the more additive you add, the flatter the resulting finish will be. As a starting point, mixing half of a pint of Satin Additive into a quart of Easypoxy color will produce an effect similar to Pettit's standard semi-gloss white.
This aditive mixed easily with the easypoxy high gloss paint. The directions were easy to follow to give a "satin finish" that flowed out well. Pettit products continue to be my preferance for quality.
