ACID STAINED CONCRETE
Acid Stained Concrete
Queensland homeowners, designers and builders are becoming more and more fond of Acid Stained concrete because of the one of a kind look that can be achieved using different stains and finishing techniques on new or old concrete. The end result is limited only by the creativity of those involved in the Acid Stained concrete process. Using acid-based chemical stains, we are able to achieve rich, earth-toned color schemes resembling natural stone or marble, giving a completely custom look to concrete floors, concrete driveways, patios, walkways, pool surrounds and more.
Most acid stains are a mixture of water, hydrochloric acid, and acid-soluble metallic salts. They work by penetrating the concretes 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 absorb into the concrete 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 varies depending on the color and condition of the concrete surface 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 large color selection. You'll mostly find them in a limited range of subtle earth tones, such as tans, browns, soft blue-greens and terracotta colours.
