The NPT® MM-84008D is French Gray Dry Plaster Pool Finish Pigment. NPT® pool finishes are exquisite mixtures of color and texture in an array of spectacular blends. While our formulas are accurate and consistent, the color of your pool's water will be uniquely yours. The secret to having beautiful pool water is selecting the right interior pool finish for you. The deeper the water, the darker it will appear. Water will seem lighter in shallower areas like steps, ledges, benches, and beach entries where the finish itself is more visible.
