Services > Acid Stain
Acid
stained concrete is one of the most popular
applications for transforming concrete slabs. Often
referred to as colored concrete, homeowners,
designers and builders are drawn to stained concrete
because of the unique outcome that can be achieved
combining colors, application techniques, etc., on
cement flooring. The results are limited only by the
creativity of those involved in the stained concrete
process.
Because of concrete's
porous qualities and neutral tone, it is the perfect
blank canvas for topically applied color. Using
acid-based chemical stains, decorative concrete
contractors have been able to achieve rich,
earth-toned color schemes resembling natural stone,
marble, wood, or even leather, giving a completely
custom look to cement floors, concrete driveways,
patios, walkways, pool decks, concrete walls and
more.
Most acid stains are a
mixture of water, hydrochloric acid, and
acid-soluble metallic salts. They work by
penetrating the surface and reacting chemically with
the hydrated lime (calcium hydroxide) in the
concrete. The acid in the stain lightly etches the
surface, allowing the metallic salts to penetrate
more easily. Once the stain reacts, it becomes a
permanent part of the concrete and won't fade, chip
off, or peel away. Like stains for wood, acid-based
stains are translucent and the color they produce
will vary depending on the color and condition of
the substrate they are applied to. Each concrete
slab will accept the stain in varying degrees of
intensity, creating natural color variations that
bring character and distinction to each project.
What acid stains don't offer is a broad color
selection. You'll mostly find them in a limited
array of subtle earth tones, such as tans, browns,
terra cottas, and soft blue-greens.
