Loftier-Quality Pigment

Avoid the cheap stuff: good paint lasts longer and covers better
Expensive paint has more than pigment and resin, and though it may wait the aforementioned as the cheap stuff, there are big differences in the ingredients and in long-term operation.
You might likewise similar: TBD
Overview
Imagine the perfect latex paint. It sticks to anything, covers in one coat, levels smoothly, is potent nevertheless flexible and lasts for decades. It never fades or chalks. It discourages mildew growth and is formulated so you can apply information technology in common cold atmospheric condition. And it doesn't baste. Unfortunately, that perfect pigment has yet to be adult. Never will be, either. The ingredients in a batch of pigment just have besides many limitations and merchandise-offs. Merely while there may be no such thing equally perfect paint, there are definitely high- and low-quality paints. Here we'll wait at the differences, particularly as they utilise to exterior latex paints. And why it'southward worth information technology to buy the good stuff.
Effigy A: High Quality vs. Low Quality
High-quality paint has more total solids (pigments plus resins) and fewer solvents than lower-quality pigment. And then while the two may get on with the same thickness, when the solvents evaporate, a high-quality pigment leaves a thicker, tougher paint film.
Low-quality paint has fewer solids and more than solvents. Once the solvents evaporate, the thinner pigment film left backside is less durable and doesn't encompass equally well. You'll spend more time and money repainting to reach the operation of a high-quality paint.
What is paint, anyhow?
To most of u.s., 1 opened tin can of paint may expect pretty much like the side by side, only not to the chemists who codify it. A typical batch of latex base of operations paint—the untinted pigment to which colorants are added in the store—can incorporate 15 to 20 ingredients or more. Base paint ingredients can be lumped into four categories:
Pigments are finely ground particles that give paint its opacity and ability to "hide" the surface it'southward applied to. (Colorants are the tints added at the hardware store or home center to produce the exact color yous want.)
Resins (or binders) are the ingredients that hold the pigments and colorants in place later the pigment dries.
Solvents (besides chosen carriers) are the liquids that transport the above ingredients from the brush or roller onto the wall. In latex pigment the principal solvent is water; in oil-based pigment it'due south primarily mineral spirits. These evaporate equally the paint dries.
Additives are the chemicals that touch on everything from mildew resistance to workability.
To empathise how latex paint works, picture a bathtub full of h2o and Ping-Pong balls. Some Ping-Pong assurance are white, representing the pigments. Others are—let'south option a color—ruddy, and represent the colorants. Some are clear and exceptionally viscid and stand for the binders. The h2o they're all bobbing in is the solvent. As the bathtub drains (that is, the paint dries), the clear Ping-Pong assurance link together, trapping the white and red balls in a tight mesh. Bingo, there'south your paint film. The purity, quantity and size of all those Ping-Pong balls are what dictate pigment quality.
High-quality paint has better pigments, so it hides improve
The predominant and near expensive pigment in pigment is titanium dioxide, a very pure white powder with exceptional hiding qualities. High-quality paint contains a high per centum of this paint. Other, less expensive pigments such as clay, silica and talc are institute in expensive paints only are more prevalent in cheap paints. They're not as white and pure, and they're poorer "hiders," meaning y'all'll need to utilize more or thicker coats of paint to comprehend existing colors (Fig. B). Y'all can't really judge the quality of a pigment by the amount of pigment in it; for instance, flat paints ever incorporate more pigment than glossier paints. Simply you'll certainly observe better-quality pigments in expensive paints.
Effigy B: Amend Pigments Hateful Meliorate Coverage
The pigments in the loftier-quality pigment on the left are smaller and purer, so they do a meliorate chore of filling in and blocking the color of the surface they're practical over
Loftier-quality pigment has better resins and then it sticks improve and lasts longer
Resins—sometimes chosen binders—are the plastic-like ingredients in pigment that bind together to create a flick, encapsulating the pigments. The best latex resins are made of acrylic, and the best acrylic resins are made from small particles that can deeply penetrate the wood pores and "catch on" (Fig. C). That's why high-quality binders final longer and better resist blistering, peeling and clothing. At the store, yous'll commonly notice paint labeled ii means: "100 percent acrylic" or "vinyl acrylic." Buy the higher-quality 100 pct acrylic paint.
Sleeky paints contain more than resins and less pigment than flat pigment; it'due south the resins that make a glossy paint glossy. Only a high-quality gloss paint will have more than resins than a depression-quality gloss paint, and those resins volition be higher quality. Since resins are the most expensive component in any pigment, high-quality paint with high-quality resins is more than expensive.
Figure C: Meliorate Resins Means Better Adhesion
The resins in the loftier-quality paint are smaller and better able to cling to each other and penetrate the surface they're applied to. This ways a stronger, longer-lasting pigment picture.
High-quality pigment has more solids
By now we know that paint sheen is adamant by the ratio of binders to pigments: Flat paint has more pigment and less resin; sleeky paint has less pigment and more than resin. But pigment sheen bated, high-quality paints volition accept more combined solids (pigments and resins) and less water than cheap paints. Our expensive gallon of pigment contains as much every bit 45 percent solids by volume, while cheap stuff may accept less than xxx percent (Fig. A). A college percentage of solids means a thicker pigment film, better hiding and greater immovability. The remaining ingredient in a can of latex paint is primarily h2o, the cheapest ingredient of all, with the sole purpose of carrying the binder and paint to the surface before evaporating.
High-quality paint has additives that better its application and protective qualities
All latex paints contain additives, but loftier-quality paints contain more or better ones that also cost more. Thickeners, which can significantly increase the cost of a gallon of paint, slightly tedious down and smooth out your brush stroke and so you leave an even, thick coat of paint. The high-quality latex paint now available volition brush on almost every bit smoothly as oil paint. Surfactants assistance paint soak into the woods and attach ameliorate as well as help stabilize the color and viscosity of paint. Mildewcides limit mildew growth after the paint has been applied (at least for a few years).
Other additives protect the quality of the liquid pigment if it freezes a time or two, foreclose the paint from foaming when mixed or help the paint flow ameliorate from brush to surface. These additives increase the cost of high-quality paint.
The lesser line
100% acrylic paint
Retrieve, you get what you pay for.
Even if exterior latex paint ingredients were listed on the can like the ingredients on a can of soda popular, it would be tough comparing paints and sorting the skilful from the bad. We could wait for paints with more solids, higher-quality ingredients and improve additives. But nosotros're practise-information technology-yourselfers, not chemists! Paint chemists are a secretive grouping anyway; they practice a lot of inquiry and testing and don't like other paint chemists knowing their paint recipes.
So most experts—both chemists and pro painters—will just tell yous this: Buy paint that's 100 percent acrylic, and buy paint that's expensive (preferably on sale). You'll become more for your money and labor! A loftier-quality exterior latex paint tin last 10 years or more, compared with iii to four years for a inexpensive paint. That makes it less expensive per square foot per year in the long run and easier to maintain.
