Concrete acid stains create color by reacting chemically with the calcium in concrete rather than using pigments. Because the color results from this reaction, they are not true paints. The final color varies depending on the concrete’s type, quality, and cement content — higher-grade concrete yields deeper, richer tones.

Higher concrete grade or more cement amount available on concrete surface will lead to higher paintability rate. For this reason, the final color of the acid stain is determined after its reaction with the concrete surface.
This product can be applied to the surface with a low-pressure pump (all-plastic spraying pump) or a brush. (For more information, refer to this product manual file.)
Keep in a sealed container, dry and low light environment at a temperature of 15-40 degrees Celsius. In case of contact with skin, wash immediately with plenty of water. Immediately see a doctor if swallowed. This solution is free of hazardous evaporative and non-flammable materials. Due to the acidity of this product and reaction with metals, it should not be stored in iron, aluminum, copper, brass, zinc or galvanized containers.
Concrete stain colors are provided in 1 and 5 kg plastic gallons. These materials must be kept in the sealed containers.

Due to the acidity of this product, all-plastic equipment must be used to move,
maintain and spray it on the surface.
To apply acid stain on concrete, it must have passed 7 days since the concrete
was applied and the concrete has reached its initial strength.
It is better to apply a clear polymer or protective silicate coating on concrete
surfaces where acid stain is applied.

COUPCOLOR® CAS is a penetrating color liquid designed for staining all types of concrete surfaces, both old and new. It reacts with the surface to provide a long-lasting color while being fully absorbent. Key properties include a liquid appearance, ≥ 98% purity, a pH of 2–3, and a density of 1.2 g/cm³. It is highly stable under normal conditions and resistant to UV light.
Due to the acidic nature of this product, it is necessary to wear chemical safety goggles, body protective clothing, chemical-resistant gloves, and rubber boots. All-plastic equipment should be used for handling, storage, and application. Avoid direct contact with skin, eyes, and inhalation of spray mist.
Eye contact: Rinse eyes with plenty of water for at least 15 minutes and seek medical attention.
Skin contact: Wash immediately with plenty of water, remove contaminated clothing, and get medical care.
Inhalation: Move to fresh air; if not breathing, give artificial respiration and seek medical care.
Ingestion: Do not induce vomiting; seek urgent medical attention.
The product is non-flammable but should be stored away from metals like iron, aluminum, copper, brass, zinc, or galvanized containers due to possible reactions.
