Picking up a paintbrush may seem like a straightforward home
improvement task. But in truth, this simplest of home improvement
projects may too often be just a little more complicated than what
meets the eye. Poor preparation, bad brushes and just plain lousy
technique can turn your painting project from fabulous fresco to
something that really misses the masterpiece mark.
Over
the last 10 years, I’ve fielded hundreds of questions to my national
radio program, The Money Pit, from frustrated folks who were trying to
solve a myriad of painting problems. Here are a few of the most common
culprits and the solutions you need to save time, money and your pride!
GET READY, GET SET -- THEN SAY GO -- Getting the right equipment before you start the job means you won’t
have to stop in the middle of the job to run back to the hardware
store. You’ll need ladders, drop cloths to protect sidewalks and
shrubbery, long handled paint brushes and rollers, a paint sprayer and
tape for trim and detail areas. Also, don’t go cheap on the brushes.
Better quality brushes deliver a smoother finish and the difference
really shows. Keep in mind that brushes are available in both synthetic
and natural bristles, also known as “china” bristles. For best results,
use synthetic brushes for latex paint and natural bristles for oil
based paint and clear finishes.
PREP MAKES PERFECT -- The success or failure of any paint project rides at its roots on
one basic need: the paint has to stick. It’s not surprising then that
much of the effort of any paint project goes into making sure this
happens. Paint won’t stick to a loose or dirty surface. Between air
pollution, mold, mildew and the deteriorating effects of the sun,
there’s a fair amount of work that must be done to get the surface
ready to go. For exteriors, pressure washing is a great first step to
remove old paint and clean dirty or weathered sources. With a
combination of a high-pressure stream and a bleach cleaning solution,
you’ll knock days off doing the job by hand. If you are working inside,
use liquid sandpaper to remove oil, dirt and grime from trim and wash
walls down with a TSP (tri-sodium phosphate) solution which is
available at most home centers and hardware stores.
PREPARE, THEN REPAIR -- Now that you can see the wood surface underneath the old paint, you
should check for rot, warping and insect damage. Replace any damaged
boards around windows and doors, and have your local pest control
company inspect any damage you think is insect-related. Take the time
to inspect all surfaces carefully, being alert for anything out of the
ordinary. If there is loose, bubbled or peeling paint, it usually means
there is a leak and you need to check for a water problem. It’s
critical to not just ignore these symptoms and paint over them. If the
underlying cause is not found and fixed, it will only get worse. This
is also a great time to caulk any holes and gaps to improve energy
efficiency.
PRIMING MAKES PERFECT -- Primers
are critical coatings that must be applied to provide a firm bond
between the substrate and finish coat. Although most do-it-yourself
painters look forward to getting to the color coat as soon as possible,
skipping the primer step is short-sited. Primer is the “glue” that
makes the top coat stick. Skip it and you’ll find that the hours of
preparation and painting work you put into your projects might have to
be repeated long before the paint surface wears out.
Primers
like KILZ are available in both oil and water base formulas. For
surfaces that are badly stained, or that have had a water leak, oil
based primers work the best. When using oil-based primers, it is
usually a good idea to prime the entire surface you are painting and
not just the stained areas. Since oil primers do such a good job of
sealing the surface, spot priming may result in an uneven finished coat.
PICK THE RIGHT PAINT -- Exterior paint is different than interior paint, and many homeowners
make the mistake of not choosing the right paint for their home.
Exterior paint is formulated for color retention, flexibility to
withstand expansion and contraction due to weather, resistance to
tannin bleed and resistance to mildew. Exterior flat acrylic latex
paint is the easiest for do-it-yourselfers to work with. For trim,
consider a durable alkyd/oil paint that offers high gloss with good
adhesion and stain resistance. When it comes to buying paint, don’t buy
discount brands. You get what you pay for when it comes to paint and
the lower the cost, the shorter life it will have. Since paint is 90
percent hard work and 10 percent material, always buy quality paint
from a name brand company.
Also, always buy a bit
more paint than you think you’ll need. Surprisingly, many stores are
willing to accept returns on unused paint, even if it is a custom
color, and having the extra means you’ll avoid color matching problems
if you run short and need more. Before you start your paint job, check
the temperatures. Paint won’t adhere if it’s below 55 degrees or won’t
go on smoothly if it’s above 90 degrees.
NO BAD PAINT -- JUST BAD PAINTERS -- Blaming the paint for an unacceptable result is quite common. Some
years ago, a friend mentioned to me that he must have had some “bad
paint” because the top gable section of wood siding we were repairing
had blistered very badly. My buddy had installed the siding and painted
the entire home himself about four years earlier. Upon closer
examination, the real culprit became obvious. The “painter” had
neglected to “back-prime” the siding in the gable. Back-priming refers
to the technique of priming all surfaces of exterior siding before it
is assembled, including the back of the board. By doing so, you can
control the amount of moisture absorbed by the board from behind and
prevent early paint failure. When I mentioned this to my friend, he
recalled that he had completed siding the entire home but ran short of
material for the section that failed. When the remaining material
finally arrived, he was in a rush to get it completed and took a short
cut that he is now paying for.
In truth, paint is
manufactured in factory controlled conditions in huge vats that hold
thousands of gallons at one time. It is virtually impossible to have a
“bad” can of paint exit from this environment and make it into your
shopping basket at the local superstore. If you spot a paint failure,
the cause is usually something much more common…like human error!
