Painting the office or school corridor is different from a home project. Instead of weighing the merits of this year’s hottest color, FMs have
to prioritize longer durability, better resistance against abuse and the strength to
hold up to washing and scrubbing.
The right paint for your repainting project is out there, but do
you know how to find it? Determine what makes a product the
right one with this guide to the types and ingredients of paint.
Understand Paint Types and Formulas
Paints are typically categorized according to resin type and
where the paints are used, notes Brian Osterried, Product
Manager for PPG Architectural Coatings. Latex, oil-based or
alkyd, and waterborne alkyd are the major categories of paints,
and each will be marked according to where it can be used
in your facility, such as interior, exterior, wall, trim or
floor, he adds. Any one of them can be paired with a
primer if needed, though some paints are adver-
tised as self-priming.
“Interior paints are typically designed
for the durability, washability,
scrubbability and burnish
resistance of everyday use and abuse inside buildings,” explains
Rick Watson, Director of Product Information for Sherwin-
Williams. “Typically, an interior paint doesn’t have to concern
itself with sun, rain, wind, snow or temperatures that fluctuate
significantly. The reverse is true on the exterior because those
paints must have performance characteristics associated with
fluctuating temperatures, dirt, wind-driven rain, hail and the
sun beating down on it all day long. It’s not necessarily about
coffee, tea and ketchup stains like it is on the inside. Whether
it’s indoors or outdoors, primers really don’t have to stand up to
the beatings that topcoats take – they just have to take care of
sealing and providing good adhesion for those topcoats.”
Regardless of its intended application, all paints have four
Carriers (solvents or water): All of the other ingredients
are suspended in this liquid, which evaporates after application and is not present in the final dried paint film, Osterried
explains. Carriers allow the product to flow and level appropriately. Solvents are used as the carrier in oil-based paint, while
water is used for latex products.
Binders (also known as resin): Ensures that the paint
sticks to the surface and makes the film more durable.
Binders are the “glue” that holds everything else in the can
together, says Debbie Zimmer, Paint Quality Institute
Director of Communications and Alliances for Dow
Coating Materials, North America.
Pigments: These add color and opacity.
Binders and pigments are the two biggest
components in a can of paint, Zimmer
notes: “Pigment is not the color
that you get at the point
