Ibw to paint How to pick a stain amid
exterior surfaces burgeoning technologies
a*
There are many considerations to take into account during exterior applications. The
following suggestions work
whether you are painting over
wood, cement, fiberboard,
trim, stucco, brick, etc.
First, determine if you are
painting a surface for the first
time or are actually, repainting
a previously coated, substrate.
Many people look at their
wood and assume that they are
painting wood, when actually
they are re-painting a previously applied coating. Once
this has been determined, consult your Pittsburgh Paints
dealer for the proper primer
and topcoat recommendation.
Secondly, prepare the surface. The most important thing
to remember is that topcoats
do not "heal" a bad surface. It
•will temporarily hide it, but
the failures will reoccur, and
may be worse when it happens
again. Touch the surface and
see if there is chalking or a
white,
powdery
texture.
Examine the surface for cracking, peeling, mildew, ,dirt or
water damage. Be aware of
how old or fresh the surface is,
especially if you are painting
cement or a surface that has
high alkalinity. Scrape all
peeling paint, sand glossy
areas, spot prime bare wood
and wash the entire surface to
remove dirt. Apply a Mildew
Check Multi-Purpose Wash to
retard the reappearance of
mildew on your prepared surface.
Third, be aware of the
weather conditions when you
paint. You can make or break
a paint job by applying paint
over a surface that is too cold,
too hot or too damp. Do not
paint when temperatures are
below 50 degrees Fahrenheit
(unless otherwise noted in the
literature) or above 100 F. For
best resaults, do not paint in
the direct sun or if rain is
expected within-24 hours.
You will protect and beautify your buildings for years to
come when you do not short
cut your application and paint
decisions. The benefit is
yours.
As a global leader, Pittsburgh
Paints provides a full line of exterior stains, encompassing many
diffemt technologies. Each technology is designed to handle
nature's harshest elements: sun,
rain and mildew. Pittsburgh
Paints Sunproof stains are available in alkyd/oil, 100 percent
acrylic latex and acrylic/oU-penetrating formulas.
As both the environment and
the lifestyle choices we make
change, we are finding that the
products from 25 years ago no
longer fit today's needs.
Although Pittsburgh
Paints
offers a complete array of technologies, government regulations
and new upcoming legislations
are continually impacting the
products that Pittsburgh Paints
can ship into certain regions of
the country. At the same time,
more people prefer the ease of
soap and water clean-up products. Finally, technological
advances are coming in leaps and
bounds. The best technology in
the past (oil stain) is no longer
leading the durability category.
These are three examples of why
the technologies in the stain market are being reshaped.
One of the new technologies
that Pittsburgh Paints has available in the SunProof Stain line is
acrylic/oil. This penetrating oil
technology is considered to be
the wave of the future. The
acrylic/oil technology has been
perfected over the past 10 years
and is changing the stain market
for the better. This new technology offers superior color retention
when compared to alkyd/oil technology, the flexibility of being
applied at a broad range of temperatures, and soap and water
clean-up. In addition, the penetrating oil component preserves
and enhances the natural beauty
of wood. Products made with this
technology do not have any of
the milky appearance that has
been seen with latex coatings of
the past, and maintain the longer
durability that is commonly
attributed to latex coatings. This
new technology is available
nationwide and if is the only
technology available in areas
where VOC's (volatile organic
compounds) are regulated.
The acrylic/oil technology
works so well because of an
interesting curing mechanism. It
has an alkyd core, with an acrylic
shell. This two-stage dry yields
excellent open time, lap resistance and stability. The oil penetrates into the wood leaving a
protective shell providing double
protection for the wood. This
means that the acrylic/oil technology has the benefit of an
alkyd in the brush, feel and application, and the benefits of a latex
in durability and color retention.
This state-of-the-art acrylic/oil
resin provides the best of both
worlds and is poised to become
the wave of the future.
