What is the difference between a paint and a coating? |

All paints are coatings, but not all coatings are paints. |

ASTM E631-06:
Coating: liquid, liquifiable, or mastic composition that is converted to a solid protective, or decorative, or functional adherent film after application as a thin layer.
Paint: in general, a pigmented coating.
Paint Quality Institute:
Coating: A paint, stain, varnish, lacquer, or other finish that provides a protective and/or decorative layer over a substrate.
Paint: An opaque coating generally made with a binder, liquids, additives, and pigments. Applied in liquid form, it dries to form a continuous film that protects and improves the appearance of the substrate. |

Now let's look at mastics.
09 96 46 Intumescent coatings
07 81 23 Intumescent mastics
Why? Is it the application? Isn't the work result more important than the application technique? Is application technique the difference between mastic and coating?
Why arn't both of these in 07 8x xx

I would look for a full 1-hour min rating on a 07-8xxx listing and an E-84 flame spread reduction coating in the 09-96xx area and no E-119 rating. |

I treat 07 81 23 as tested assemblies for fire-resistive-rated construction, and 09 96 46 as protection to certain elements from fire but do not require a particular code-established rating.
Marc, since you're in Seattle (Starbucks capital), what's the difference between "mocha" and "coffee"? (It all tastes the same to me--yuk!)

Originally, a City in Yemen that was famous for trading coffee.
It’s also a name for a variety of beans
In modern parlance, it is a drink made of espresso and cocoa (usu. a chocolate syrup, which contains very little actual chocolate) and milk. Think of it as hot chocolate with a shot of coffee.
When ordering my favorite variety of mocha I state the following:
“I’d like a grande skinny mocha, extra shot, no whip with hazelnut” |

So...if I follow your logic...paint is to coffee as coating is to mocha???
From a marketing or manufacturing standpont, traditionally, the paint companies did architectural coatings and the high-performance coating companies did industrial coatings. Now those lines are blurring and the hi-perf coatings folks are becoming more paint-ish and the paint folks are doing more higher performing coatings.
Perhaps one day we will be calling paint "decorative coatings" and high-performance coatings "performance coatings" and anything in the middle "decorative-performance coatings"
