Stain and Seal
Staining concrete is one of the most popular applications for
transforming concrete slabs into something that looks far more
elegant than typical flooring options. Often referred to as colored
concrete, homeowners, designers and builders are drawn to stained
concrete because of the unique outcome that can be achieved by
combining colors, application techniques, etc. on cement flooring
and other substrates. The results are limited only by the creativity
of those involved in the stained concrete process, including you!
Because of concrete's porous qualities and neutral tone, it is the
perfect blank canvas for topically applied color. Using 100%
environmentally-friendly acid-based chemical stains, concrete
artisans 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, 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. However, newer products on the market such as
water-based penetrating stains and water-based and
solvent-based concrete dyes are greatly expanding the artist's
palette with colors ranging from soft pastels to vivid reds,
oranges, yellows, and purples.
