What Makes It Work? - One Coat Paint


To discuss what makes a One Coat Paint we should first review how paint is made.


Today there are two basic paint types, latex or water-based paint and alkyd or oil-based paint. Despite being called oil-based paint alkyd paints do not contain any oil; they use a different binder and thinner than latex paint and mineral spirits is used as a thinner.



All Paints have four main ingredients, resin, solvent, additives and pigment. The resin is the binder, it allows the paint to adhere to the surface you are painting. The solvents are water or mineral turps these are the binder that hold the resin and pigments together. Additives are used to enhance the paints performance, such as mold resistance, improvers to enhance flow, leveling, sag resistance and durability. The pigment gives the paint it's color and sheen level, flat, satin, semigloss or high gloss.



A paints performance then is dictated by its formula, high end paints such as Behr Marquee have high levels of additives to improve performance and durability. The pigments levels are higher to improve coverage and exterior grades contain mold resisters and UV agents to prevent fading.

So, we come to the question at hand, ‘What Makes it Work? – One Coat Paint’  The answer is the formula, one coat paints contain multiple additives to improve flow and durability, additional pigment to improve the hiding power of the paint, the pigment is finer, almost microscopic, these ultra-tiny particles bind together better to create a denser more uniform paint film, allowing for the one coat coverage. One coat paint may cost more to buy, but the additional cost is worth every penny, when you consider the time and effort saved by not having to apply a second coat.

Marquee covers better because it has considerably more white pigment and more tint to compensate for that extra white pigment. Some Marquee formulas have over 19 ounces of tint!
Also note that original Marquee pallet had very few bright,clear colors. Most are dulled , subdued colors. Dulled colors simply cover better than clear colors. Dulling usually occurs by the addition of the "organic" tints, such as lamp black and raw umber. Organic tints are better at blocking light transmission than inorganic tints, i.e. the primary and secondary colors.
The size of the pigments in all Behr paints are the same for the sheen level and have very little to do with how well it covers. Obviously, "deep base" paints have absolutely no white from the factory. ALL tinted Behr paints are using the same tints, therefore the covering ability is not determined by the size of those pigments, but rather from the amount and nature of the tint color used.
Were pigment size a determinant in how well a paint covers, semi-gloss, with its very fine pigments, would cover better than flat paint - it doesn't! Were pigment size a determinant, Behr Ultra, with its nano sized particles would cover better. Indeed, the nano particles are so small that light rays don't even "see" them and they do not affect the color or coverage of the paint at all!
