No
substrate category has more sales potential than masonry.
First, consider that the "masonry" market is comprised not
just of brick and stucco homes and buildings, but also those
made of cinderblock, cement block and EIFS.
Then
consider that many masonry surfaces require multiple coatings
for both surface preparation and topcoating. When you do
the math, you realize that this is one market you can't
afford to miss.
What's
especially exciting about masonry is the wide variety of
great masonry coatings now on the market (and more soon
to come). With the aid of these products, masonry can now
be painted every bit as successfully as wood.
Once
largely the domain of contractors, today's masonry products
cover the entire spectrum, from those that can be used by
a novice do-it-yourselfer to those that should be applied
only by a professional painting contractor for the best
results. In any case, these products translate into big
sales potential for the paint seller.
As
more and more of your customers realize that they are not
stuck with the original color of their masonry, you have
a tremendous opportunity to introduce them to these products.
Next time you have customers who are candidates for painting
their masonry, knowledge of the following coatings will
help you steer them in the right direction.
Primed for Action - Surface Preparation,
Primers and Sealers
Good surface preparation is essential with virtually any
paint job. But this is especially true for masonry. A high
percentage of premature paint failures on masonry can be
directly attributed to improper surface preparation.
Ask
your customer if the masonry to be painted is new, weathered
or previously painted. The surface preparation that is needed
will vary depending upon the answer. If the masonry surface
is older and has weathered, recommend the purchase of the
proper tools for the job. He or she will need to clean the
surface with a wire brush, power brush or power washer.
Previously painted surfaces must also be cleaned, and any
loose or peeling paint must be removed prior to recoating.
If
your customer mentions a problem with efflorescence (white,
sometimes crusty, powder or deposits that have been carried
to the surface by moisture), it can be removed by wire brushing,
or with a 6 to 10 percent muriatic acid solution. Follow
with a thorough rinsing. Similarly, mildew can be removed
with a simple solution of one part bleach to three parts
water applied using a garden sprayer, or simply with a sponge,
then rinsed with clean water. If your customer will be using
either of these solutions, or doing power washing, recommend
that he or she purchase and use the proper safety equipment,
such as goggles and gloves.
If
your customer is painting new stucco, recommend that it
be allowed to cure for four weeks to allow for drying, shrinkage
and reduction of surface alkalinity. To help prevent the
buildup of efflorescence, the stucco can be washed off with
a hose once or twice a week during that period. After the
four-week waiting period, your customer may proceed to seal
and paint the surface.
Priming
or sealing is important on masonry because of the porous
characteristics of these materials. If the surface is particularly
chalky or produces efflorescence, a masonry conditioner
or sealer should be applied before painting to help combat
that problem. Where efflorescence is present, the source
of moisture causing it should be identified and eliminated,
if at all possible.
Keep
in mind that it is wise to use a masonry sealer on all types
of masonry - even if your customer does not plan to paint.
Sealers designed to be left unpainted help render masonry
more water-resistant and offer a degree of protection from
the elements.
Paint:
A Coating as Tough as the Surface Below
Every type of masonry can be painted, but on masonry substrates,
as with other materials, a quality product will provide
the best value. To that end, a top quality 100 percent acrylic
latex house paint is an excellent choice for masonry. This
type of paint provides excellent color retention and flexibility.
It resists the effects of alkalinity that may come from
either relatively fresh masonry or masonry that has become
damp from water intrusion. (By way of contrast, alkalinity
can attack the binder in alkyd and vinyl-acrylic latex paints
and cause fading, and even compromise film integrity through
what is called "alkali burn.") Furthermore, top quality
100 percent acrylic latex primers and paints are less prone
to pass efflorescence through, compared with highly pigmented
"economy" products.
The
binder in quality 100 percent acrylic latex paints provides
masonry with exceptional protection. But in some cases,
another type of coating may be preferable. If the house
or building will be exposed to significant changes in temperature,
cracks can form in the masonry surface. Conventional paint
- even top quality products - will not be able to bridge
those cracks. What is needed is a thicker, more flexible
coating.
Stretching Out With Elastomeric Wall Coatings
Elastomeric wall coating (EWC) systems are a good choice
for customers who live in climates with fluctuating temperatures,
and who are seeking the utmost in quality and performance
from their masonry coating. These coatings can stretch,
contract and generally conceal cracks and imperfections
that naturally occur in exterior masonry surfaces. When
temperatures drop, EWCs stretch and cover the cracks that
develop. When temperatures rise again,
EWCs
recover their original shape without warping or wrinkling.
EWCs also offer good water resistance: By stretching and
covering cracks, these coatings protect masonry from wind-driven
rain and other moisture. But EWCs do "breathe," so they
also permit moisture from within the building - or from
within the masonry itself - to escape as vapor.
If
a homeowner is interested in an EWC system, recommend that
he or she have a professional painter apply it, as this
special coating must be applied in very thick coats for
best performance.
Regardless
of who applies it, be sure to inform your customer of the
proper application procedures for an EWC. For the best results,
the masonry should first be sealed or primed. This is especially
important if the surface is particularly porous. Then the
EWC should be applied in two heavy coats, for a total dry
film thickness of at least 14 mils. The proper application
technique is by heavy-nap roller, or by spray followed by
back-rolling.
Coming
Soon... Semiflexible Coatings
With the advent and general availability of EWCs, specifiers
and consumers finally have a coating that affords great
protection to masonry. But another, somewhat related coating
will soon be coming to the North American market, one that
has been used successfully in Europe for years. This is
a high performance latex "semiflexible paint" that will
offer flexibility falling between that of conventional quality
latex paint and that of elastomeric coatings.
Compared
to EWCs, semiflexible coatings are applied in a thinner
film (dry film thickness: 4 to 6 mils in one coat, compared
with at least 14 mils in two coats with an elastomeric),
and have maximum dirt resistance. Crackbridging capability,
while not as outstanding as with quality elastomerics, is
far better than with conventional paint at normal spread
rates. As a result, these semiflexible coatings provide
protection from rain and other sources of water over all
types of masonry surfaces, both bare and previously painted.
Making
the Most of Masonry
While you may know the ins and outs of painting masonry,
it's important to remember that your customers may not.
Consider giving your masonry coatings a front-and-center
position in your store. You may also want to create a display
showing some painted brick, stucco or cinderblock, or a
photo display of painted masonry homes and buildings. Think
about including some helpful tips on painting masonry, courtesy
of the Paint Quality Institute. Most important, be on hand
to discuss your quality masonry products with your customers,
and help them obtain a quality paint job that will make
them - and you - proud.
| EIFS: The Best-Kept Secret in Masonry
If you aren't familiar with EIFS, don't feel bad.
A lot of people in the paint industry look quizzical
when they hear the name. But this is one segment
of the masonry market that you can't afford to ignore.
Believe it or not, fully 30 percent of all new commercial construction
built in the U.S. over the past several years has
EIFS cladding; in addition, about 2 percent of the
existing U.S. housing stock is EIFS. That's a lot
of potential area for a new coat of paint.
The word EIFS is really an acronym for Exterior Insulation
and Finish Systems, a multilayered wall cladding
topped off with a thin layer of acrylic-based material.
It's often referred to as "synthetic stucco." Although
the color of EIFS is typically blended throughout
the top layer, EIFS can become soiled or stained.
Even if it doesn't, the owner of the building or
home may want to change the color.
If
a customer wants to paint an EIFS-clad home or building,
recommend that he or she follow the same surface
preparation procedures as for other types of masonry
(see main article). However, it is extremely important
that you offer customers these extra precautions
concerning power washing of EIFS:
1. Make sure that all joints and seams in the material -
including those between wall sections and windows,
doors and other protrusions - are thoroughly caulked
and sealed before power washing. Otherwise, the
water could be forced into the wall cavity where
it could, due to the non-permeability of EIFS,
cause wood rot and other types of moisture damage.
2. Use plain water - without cleaning agents or bleach -
when power washing EIFS.
3. Take special care that the water pressure not be so strong
as to damage the surface of the cementitious material.
After completing all surface preparation procedures, EIFS should
be painted with one or two coats of top quality
exterior paint or elastomeric coating, preferably
a 100 percent acrylic latex coating. |
