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
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
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 Deck?
A. No. Kool Deck 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 Deck 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
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
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
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,
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.
