Q: What is Concrete Technology Inc.'s Product?
A: CTI's product is a color integrated, modified
acrylic cement product made of Portland cement, silica sand and a modified
acrylic resin for its bonding agent.Q: What
warranty is involved?
A: CTI offers a 10-year limited material warranty
against check cracking, fading, delamination, and general product failure.
Q: How thick is it?
A: We generally apply our systems on old concrete
between 3/32" to 1/8". CTI's systems are thin layered cements which depend
on adhesion through the use of modified acrylics.
Q: What does it look like?
A: CTI's systems achieve a look, texture and color
of any type stone or look you require. A base coat is applied that fixes any
imperfections in the original concrete. A design is then laid over it and a
hopper gun shoots on a textured layer over that. A final clear coat is put
over the system that is nonporous and protects it as well as makes it very
easy to maintain. Mold, mildew, motor oil, etc. can be sprayed off with a
regular garden hose. Common detergents can be used to remove tough or
repetitive latencies.

Q: What colors does it come in?
A: We have a variety of standard colors to choose
from. However, we can custom produce any color you wish for a minimal extra
charge.
Q: How long does it take to do a job?
A: An average job will take 1 to 2 days. Larger,
more complex jobs may take longer. Clean foot traffic is usually allowed
within the same day.
Q: Does the pool have to be drained?
A: No, the pool should be full. If the pool were
empty, the CTI system overspray would stain the plaster. Full, any small
amount of overspray can be dealt with by allowing the overspray to settle to
the bottom, shutting off the filter, then pumping the material to waste and
bypassing all filters is recommended.
Q: How do you treat control or expansion
joints?
A: All existing control joints should remain in
the surface to allow for expansion and contraction of the original concrete.
They are not coated with the CTI system and are masked off. We can, however,
work to insure these joints match the rest of the look of the surfaces.
Q: Is it cool to walk on?
A: Here is how CTI's systems compare to other
coatings as far as heat retention:
10-40 degrees cooler than concrete
30%-40% cooler than epoxy stone
50% cooler than vinyl or urethane
40%-50% cooler than wood decks
Up to 40% cooler than carpet
50%-60% cooler than terrazzo
40%-50% cooler than tile
20%-30% cooler than brick
Q: Is it Kool DeckŪ?
A: No. Kool DeckŪ is a product that must be
applied to freshly poured concrete within 5 hours in order to bond. CTI's
systems can be applied to new or old concrete. In addition, CTI's systems
are a three-coat system and are sealed with a finish coat, which makes it
impervious to staining. Whereas Kool DeckŪ is a very porous, non-flexible
product, that has a minimal life expectancy.
Q: Will pool water, chlorine, muriatic acid, or
bleach stain the CTI system?
A: No, the sealer we apply to our system is not
affected by most chemicals.
Q: Will CTI's systems fade?
A: No, not dramatically, the CTI product has
approximately a 2% fade factor over seven years, which is undetectable by
the human eye; our warranty covers this.
Q: Can you correct drainage and low spots?
A: We can generally improve drainage; however, the
degree of success is contingent upon the pitch of the concrete adjacent to
the low spot. The low spot will have to be looked at personally by an
authorized CTI dealer to let you know what you can expect.
Q: How do you treat cracks in the concrete
prior to the CTI application?
A: Cracks are ground out with a cup grinder to
produce a "V". A two-part epoxy with a chopped fiberglass filament is then
introduced into the crack and will re-bond the crack.
Q: Will cracks reoccur?
A: Though we do everything possible to treat
cracks and do eliminate 90% of them, it is possible they may reoccur. If
they do, it is usually in the form of a hairline, which is not objectionable
as it is largely hidden in the texture. However, if a crack becomes too
objectionable, it is easy to repair. Proper placement of tension cuts
greatly reduces the chance of the crack returning.
Q: What if something happens to my deck after
the warranty?
A: The material is repairable to its original
state. We service all decks past warranty.
Q: Can you apply the CTI system over painted
concrete?
A: Yes, though it generally will need to be
scarified or sandblasted to remove the paint enough to where our product
will bond with the original concrete.
Q: Can the CTI system be applied to steps?
A: Yes, CTI's systems can be applied to concrete
steps including risers and treads.
Q: Can the CTI system be applied to walls?
A: Yes, however, multiple spray coats are needed
to reduce rebound, or waste.
Q: Do you apply the material to cantilever
faces and coping stones?
A: We do apply CTI's systems to cantilever faces
and coping stones. Though application over coping stones is a matter of
personal preference, it is often advisable to coat the stones unless they
are exceptionally new. If not coated, they tend to look old and dirty after
the CTI installation is complete. In addition, the older copings which have
deep lips can be filled in so the coping stones are level with the deck
giving a modern cantilevered look.
Q: If the coping stones are not covered, will
the CTI system be higher?
A: No, CTI's systems are feathered very thin at
the joint edge so the coping and decking will be level.
Q: How long has this product been in use?
A: Acrylic decking has been in use since the early
70's. Our manufacturing facility has been producing coatings since 1968.
Q: Can you level heaved concrete?
A: Yes, quite easily.
Q: How does the price of CTI's systems compare
with removing and replacing old concrete?
A: The cost of the CTI system is normally 20%-25%
less than the cost of removing cement and pouring new and is much better
looking and much easier to maintain than the original cement.
Q: What is the cost per square foot?
A: The price depends on a number of factors, such
as the condition of the original concrete, the patterns chosen, etc.
Q: How do I clean the CTI surfaces?
A: Usually, normal washing with a hose is all that
is needed. For stubborn stains, a brush with laundry detergent is all that
is needed.
Q: I know concrete is strong and durable, how
does CTI's systems compare?
A: CTI's systems are harder than concrete. Most
concrete has a compressive strength of 2000-2500 psi rating. CTI's system
has a 7000 psi rating. |
