Understanding What it takes to Determine Paint Quality
When you consider the different manufacturers, types, and colors of paint
on the market, there are literally thousands to choose from. When painting
your home, a good place to start is by selecting a type of paint that
is made for the type of painting you want to do.
You should never use a paint that is made for the inside of your house
to do your exterior painting because it is cheaper or available in the
color you want. There is much more to paint than color that will determine
how well it covers the surface, how the color will look, and how long
the paint job will last.
The Price of Quality
Exterior paints typically cost more than interior paints because they are
made to be more durable and provide better coverage. A good quality exterior
paint may cost as much as $40 a gallon, but you can’t judge paint
by price alone. If you know what to look for on the label of the paint
can, you may be able to find good quality paint for far less.
Oil vs. Water Based
The age-old debate over oil- and water-based paints has gone through some
changes over the decades. Water-based paints are labeled as latex, but
are not based on vinyl and acrylics, according to This Old House.¹
Many people consider oil paint to be more tedious to apply and clean up,
since mineral spirits or other types of paint remover must be used. Water-based
paints, on the other hand, can be easily cleaned up with water.
Research¹ has shown that there are other advantages to water-based
paint, including the tendency to expand and contract with siding and allowing
water vapor from inside the home to pass through. Oil-based paints block
moisture and have no flexibility once dried. The end result is often seen
as paint blisters and cracks.
Painting the home exterior may be more expensive and end up looking aged
and worn well before its time
but if the previous paint was oil-based, and there have been no problems,
experts may recommend using the same type of paint for the new paint job.
The quality of pigment in the paint is equivalent to the paint itself.
The better the pigment, the more likely it is to cover the wall in a single
coat. Paint with lower quality pigment is the cheaper paint that takes
numerous coats to get coverage. This is why cheaper paint can often end
up costing you more, in terms of the volume of paint required and the
labor it takes to apply it. Titanium dioxide is considered the best pigment.¹
Once the liquid portion of the paint has dried, the solids remain on the
wall. Look for paints that have more than 45% solids to get proportionally
better coverage. This information isn’t normally made available
on the label, so you may need to research paint brands online to find
what you are looking for.
The binder holds the pigment and other solids together to create the paint
film. The best exterior paint is latex with an all-acrylic binder that
increases durability and resists damage from the elements.
Wall preparation differs according to the paint you choose and the condition
of the walls you will be painting. Without proper priming and application
techniques, a paint job using the highest quality paint may turn out badly. Trust
