Until now decorative concrete has been limited with tile, terrazzo or marble each having its disadvantages when it comes to design options.
Concrete dyes and acid staining open up endless possibilities of unlimited colour, patterns and custom designs. Combine concrete staining with polished concrete and you transform dull grey concrete into an architectural low maintenance finished concrete floor.
Available in water and solvent-based formulations are greatly expanding the artist's palette with colors ranging from soft pastels to vivid reds, oranges, yellows, and purples. Translucent dyes penetrate the concrete drying in less than one minute. Therefore, the colour application is completed about 60% faster than a typical acid stain due to reduced dry time and less cleaning. Combine the use of concrete dyes with polishing or a urethane-based sealer to achieve a spectacular finished concrete floor. In conclusion, dye is a powerful solution in virtually any application when the client is seeking rich mottling effects with minimal installation time.
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.
