Stained concrete as flooring used to
be rare, and a trend flooring option. In the last decade, it
has exploded onto the market and has achieved a firm acceptance by
homeowners, builders, architects, and designers.
Acid stains create a unique look giving
concrete visual character which cannot be achieved by using a
conventional polymer or pigment type stain. When placed on a
cementitious surface, the single component coloring solution of acidic
metallic ion particles (acid stain), chemically react with the particles
in the cement (free alkali) to form oxides. Typical paint or coating
stains cover up the concrete, while chemical stains infuse the color
into the surface to become a permanent part of the substrate which will
not crack, chip, fade or peel. The resulting effect creates a
translucent, variegated effect, showcasing the character of the
substrate. Depending upon the cement content, age, porosity and manner
in which hydration took place, the chemical stain will react differently
every time. These variables cause broad drifts in color and mottled
surface effects which are not considered defects, they are the reason
for it’s inherent beauty.
Acid stains transform your concrete into a
rich and inviting surface that can fit into virtually any design plan.
Available in a warm palette of earth tones, adding scored designs,
multiple colors, and unique staining methods can produce a showpiece
upon which any decorating style will blend.

A word of caution on interior stained
concrete: Many concrete slabs are flawed from carpet tack strips,
tile mortar, non-removable stains, previous coatings, or are just
poorly finished. These slabs are not likely to provide the
beautiful finishes commonly seen in photos here and elsewhere.
However, with a low cost concrete overlay placed after proper
surface preparation, the professionals at Dalcrete can provide you a
restored concrete surface tailor made for our stained concrete
finishes. Our concrete overlays are hand finished with
techniques designed to mimic the burnishing of steel trowel and
power-trowelled concrete to give rich variations just like new
Considerations When Selecting Acid Stain
choosing Acid stain as a color choice
and finish for Concrete it is necessary
to be educated on its limitations.
The end user should be aware that the
basic principles which make Acid
Staining so beautifully mottled,
variegated and marbleized can also cause
some undesirable results.
Acid Stain in its packaging is often a
translucent color that does not
represent the final color that the
concrete surface will become after the
reaction and finishing takes place.
Many tan and amber Acid Stain colors

and black is generally anything but.
color will not be evident until the
Stain has completely reacted with the
cement substrate. The reaction
takes place over a period of 1-8 hours
(depending on the manufacturer).
Additionally, the color when dry is
usually altered to a deep wet look
coloration with the application of
solvent based sealers, though a water
based sealer can maintain the soft look
of the acid Stain when dry.
Acid Stains add translucent colors to
the concrete surface and do not hide the
imperfections of the concrete.
