concrete is a system of adding colors, patterns and texture
to a plain concrete slab at the time of pouring. A finished
stamped concrete surface gives an attractive,
three-dimensional, two-toned appearance. With stamped
concrete you can create the realistic effect of slate,
stone or brick or even a custom design and
imprinted in concrete.

Broom finishes- one
the decorative concrete finishes, a broom finish is the most
common. A consistent 4” slump is recommended for concrete
flatwork with color. Schedule placement of decorative
concrete when weather is favorable. Place as many pours as
manageable in the shortest amount of time so that each
individual pour dries in the same weather conditions as the
concrete placed around it. Colored concrete will accept all
of the conventional hand tools, walking tools and
kneeboards. Tool joints or saw colored concrete as you would
any other job
finishes can be light broom or coarse depending on the
bristles of the broom you choose. This is not a fancy finish
but is attractive and provides a non-slip surface.
Plain concrete finished with
a fine concrete finishing brush can be the natural color of concrete or can be colored with
- One type of decorative
concrete that is seen more often than most others in
concrete offers a wide range of textures and an unlimited
color selection. This makes exposed aggregate on of the most
popular and attractive decorative finishes for
concrete design. A plain, unremarkable
surface has been stripped away to reveal the exceptional
beauty lying beneath. In the case of concrete, that beauty
is in the form of decorative aggregate, either natural or
decorative process of exposing aggregate has been around
since the early 1900s, well before pattern stamping,
stenciling, and decorative overlays became trendy. But this
method is far from being ready for retirement. An
exposed-aggregate finish offers numerous advantages. And
many of today’s contractors are finding creative ways to
take exposed aggregate to a new level by combining it with
other decorative treatments.
Exposed aggregate affects the
surface of the concrete. The surface of the concrete is
decorated with coarse aggregate, usually of interesting
color and or shape. Exposed aggregate finishes are rugged,
slip resistant, and highly immune to wear and weather. Exposed aggregate finishes are
ideal for sidewalks, patios, pool decks, and driveways. Commercially, they are
commonly used to allow the sidewalk finish to match or
accent an exposed aggregate finished tilt-up or pre-cast
There are two methods of producing an exposed aggregate
1 - Wash away a portion of the concrete from embedded rock.
The concrete mix typically includes a gap-graded or special
colored coarse aggregate. During placement and finishing of
the concrete, an ample amount of cement paste is floated to
the surface and then sprayed with a surface-retarding agent.
Once the concrete has reached initial set, the surface is
washed with a high-pressure washer or special nozzle to wash
away the paste and expose the embedded aggregate.
2 - "Seed" the decorative aggregate into the fresh concrete.
A standard concrete mix is placed, screened, and floated in
the usual manner. The entire surface is then uniformly
seeded with wet, clean aggregate. This seeded aggregate is
tapped into the surface of the plastic concrete and then
embedded by the use of a bull float, hand float or wood darby
until the appearance of the surface is similar to that of a
normal slab after floating. Once the aggregate is securely
embedded, and the initial set of the concrete is obtained
(when the concrete can bear the weight of a person on
kneeboards without making an indentation), the surface is
brushed with a stiff-bristle broom to remove excess mortar.
The brush is then dampened and the surface brushed again.
is then flushed with water until the water runs clear and
there is no noticeable cement film left on the aggregate.
Unlike paint-like stains, acid stains are chemically
reactive stains. These stains permanently color the
concrete, transforming it into a unique and rich palette of
colors. The uneven distribution of the cement causes this marbled effect while the concrete is being finished.
Ther many application techniques include spraying,
brooming, swirling, sponging, ragging and mixing colors. All
give different, yet fantastic results. All are guaranteed to
give you a unique surface. Exact coverage is
determined by the porosity of the concrete, weather
conditions, and application technique.
Chemical stains are water solutions
and metallic salts that penetrate and react with concrete to
provide insoluble, abrasion resistant color deposits in the
porous concrete. They contain a diluted acid to etch the
concrete surface slightly and to remove any surface laitance
so that the staining ingredients can penetrate deeper and
react more uniformly. Stains are applied to surfaces of
cured concrete that are at least one month old and free from
all foreign matter.
The chemicals used limit concrete stain colors. Black,
green, reddish-brown and various shades of tan are most
widely available. The color is not merely a surface
coating, but penetrates to a limited depth and will not
chip, crack or peel. However, it can wear away to the
