Q. What is decorative concrete
concrete overlay is a polymer modified cementitious
overlayment. I know that doesn’t answer your question
but it is a concrete like product that has polymers and
proprietary additives added that enable this product to
be overlaid or spread over other surfaces like wood, concrete,
plaster, wallboard, cement-board, or urea foam. The additives,
give the decorative concrete the ability to withstand
high humidity and dampness, UV radiation, and freeze/thaw
cycles without deteriorating. The product will mechanically
bond and chemically bond with concrete. This assures that
the product, once applied, will not delaminate. This product
can be textured or smoothed to resemble any stone product
like: marble, slate, flagstone, or field stones, in any
Q. Is there a difference between
stamped decorative concrete and decorative concrete overlay?
is a difference, lets start with stamped decorative concrete,
stamped decorative concrete is poured as a slab, like
any white concrete. After the surface has set, it will
be stamped by the contractor with special stamps that
have the desired pattern molded into to them. The surface
then is colored as desired by the customer. Sometimes
the entire pour will be colored. Decorative concrete overlay
is spread as a thin layer over concrete or other compatible
surfaces and is then stamped or smoothed and colored or
stained to give the customer the desired effect.
Q. I have a concrete side walk
that has sunken in some spots and is a real eye sore,
do I have to have it replaced?
necessarily, this product can regrade surfaces of 3 to
4 inches right to a feather edge. The cause of the heaving
of the concrete base should be corrected first, particularly
if it is caused by tree roots or a poor concrete installation.
Q. Where have decorative concrete
flooring systems been installed?
flooring systems have been installed in: casinos, shopping
malls, offices, hotel lobbies, retail stores, residential
homes, and anywhere in place of conventional tile, terrazzo,
quarry, etc. This product does exceptionally well in high
Q. I have a concrete surface that has spalded, and has
large sections that have fallen away, can this be corrected?
many cases the answer is YES, if there are no structural
issues that need to be corrected. This determination should
be made by a Structural Engineer or Certified Concrete
Q. Is indoor concrete flooring
difficult to maintain?
this flooring is no more difficult for the homeowner to
maintain than a hardwood floor. It can be cleaned with
any floor cleaning product like Mop & Glo. The floor can
also have a wax finish applied if the homeowner wants.
Overlays on wood surfaces are reinforced with metal lathe
which is secured to the sub flooring with over 25 fasteners
per square foot. This ensures that maintenance will be
cosmetic, not structural.
Q. How resistant are decorative
surfaces to stains and spills like oil or grease?
the floor or any surface is sealed by the contractor,
depending upon the type of sealant used, the surface can
be impervious to many chemicals including: salt, petrochemicals,
UV radiation, and water. This makes decorative concrete
flooring an excellent choice for driveways and garage
Q. If I happen to damage a decorative
surface how difficult is it fix?
Repairing decorative surfaces is easy; the only difficult part is matching the color. Damaging a decorative concrete overlay surface is tough because it can withstand 5,000 pounds per square inch of compressive strength. In many cases, the surface damage will be to the sealer and not to the polymer concrete.
Q. How long does it take to install
a decorative concrete floor?
The typical installation is 3 to 4 days. The floor is safe for heavy traffic by day 4.
Q. I have an older home and I wanted
to have tiles installed, but the tile contractor said
he wouldn’t do it because the floors were too springy?
Could I still get a decorative concrete floor?
Probably, yes, it would depend upon the condition of the sub flooring and the flooring joist. Decorative concrete has give to it where other stone or ceramic products would crack or fail completely. If you have floors that rattle when your family’s cat runs by, then you should have the floors reinforced before installing any flooring product.
Q. I have a friend who had a tile
floor installed in their kitchen, but now that floor is
almost an inch higher that the rest of the floors in the
house, will I have this problems with a decorative concrete
depends on the sub-floor material. If you have a concrete
floor, then the overlay can be as thin as 1/8". If
you have a wooden floor, you will see an increase in floor
height, how much depends upon the condition of the sub-floor.
A typical installation may see an increase of 1/4” to
3/8”. The other advantage is that any “valleys” you may
have in your floors can be easily trowled out. If the
floor needs to have a laun-plywood underlayment, then
this could add another 1/4” to the final height of the
Q. Do I have to rip up my old linoleum
floor before having a decorative concrete flooring installed?
Not normally. It depends upon how well the linoleum is adhered to the sub-flooring. If that is not a problem, then the decorative concrete floor can be installed right above the linoleum flooring. If height of the floor is a concern, then the linoleum will need to be removed.
Q. How long will my decorative
concrete floor last?
The indoor applications will last for decades with minimal cleaning and maintenance.
Q. I would like to use this product
over my existing driveway, is there anything I need to
be concerned when my driveway is plowed this winter?
It depends upon the texture of the finish. If the finish is like a slate or stone with a smooth finish and not many raised areas, then there is nothing to be concerned about. If the finish is similar to a cobble stone or similar finish with high and low areas then the plow or snow blower may damage the raised areas. You also should tell the plow operator not to scrape the driveway clean, but to leave a thin layer of snow. The sunshine after the storm should finish the job and this reduces the risk of damage to your driveway. You should also use sand, not rock salt or any other product to melt the snow.
Q. What is the average lead time
before I can get interior decorative concrete installed?
The normal lead time is 2 weeks. This varies depending upon the time of year. In the summer months it could be up to 4 weeks, during the winter months it could be less than a week.
Q. What type of warranty or guarantee
comes with a decorative concrete surface?
product is guaranteed against defects in labor and material.
The length of the guarantee depends upon where the product
||Interior Floors – Residential
– 5 years
||Interior Floors – Commercial
– 5 years
||Interior Walls – Residential/Commercial
– 5 years
||Interior Countertops – Residential
– 5 years
||Exterior Surfaces (i.e. driveways, walkways, patios,
stairs) – 5 years
||Pool Decks (If compaction is done by IDCD, 3 years)
Q. Is there any maintenance required
that I can’t do my self?
the finish on a hardwood floor the protective sealant
can be worn down in high traffic areas. In these instances,
the decorative concrete surface should be resealed by
a certified decorative concrete installer depending upon
the type of sealant used. If a polyurethane sealant was
used then a new coat of polyurethane could be applied.
It is recommended that you check with the contractor or
with the care guide given to you by the contractor. IDCD
has a maintenance program that addresses this issue. Please
visit that page or use this link Maintenance
Program to learn more.
Q. Is there any limit to the size
of the area that can be covered?
Simple stated NO. It would depend upon the contractor’s ability to perform the work. If the area in question is a large vertical surface, where special scaffolding would be required, then you need to contact a contractor who has done this type of architectural surfacing.
Q. What advantages are there of
decorative concrete over something like pavers.
best way to show the advantages is to use the table below:
|Problem/Issue or Concern
||Usually most distributors only carry
about a half dozen styles in stock and need to special
order anything else. Shipping charges may also be
added to the cost of the job.
||Only limited by the imagination. Find
a finish you like and it usually can be simulated.
||Weeds will grow in-between the pavers
after the first season and will require the constant
use of dangerous herbicides to remove.
||The decorative concrete surface is
solid and continuous; weeds have no place to get
a foothold and spread.
||Sink holes or depressions can form after just
two seasons. This can be caused by frost heaves
and the activities of animals and insects. This
creates a dangerous tripping hazard. The only way
to repair this is to lift the pavers replace the
missing base material and replace the pavers.
||The decorative concrete surface is solid and continuous.
It is resistant to freeze/thaw cycles and water
runs off the surface. Dangerous formations of sink
holes do not occur.
decorative concrete be applied over counter tops?
No, not over, but you can have a concrete countertop that can be made to look like almost any stone material. Depending upon the look the customer wants, the countertops can be made on site or in shop and installed. The reason for doing the countertops in shop is because of curing time and sanding of the surface. It is important for the concrete to cure before use. Some finishes may require grinding of the surface to expose the aggregate just below the surface and the dust needs to be contained.
Q. Is the surface of a concrete
countertop safe for food preparation?
Yes, there are sealants that have FDA approval, the only problem is that these sealants aren’t as wear resistant as the sealants used for floors. It is not recommended to use a knife for cutting directly on a concrete counter top.
Q. Can Decorative Concrete be applied
over an asphalt surface?
No, this is the only surface that can’t be coated. This has to do the expansion rate of asphalt and its ductility when it gets hot. The two materials are just not compatible.
Q. What happens if I don’t like
the color or I change my mind and want a different color?
depends where in the process you make this decision. Before
we begin any job you will be give a “Process Sheet”.
This sheet shows you each of the steps involved. One of
its benefits is it will show where changes can be made
at little or no cost. In the case of color, if the decorative
concrete surface has not been sealed then the color can
be lightened or darkened. The color can also be bleached
out if necessary depending upon the process being used.
