Application on stone, concrete or other mineral surfaces
Iron sulfate is often used to remove green deposits caused by moisture from surfaces such as patios, paving, facades, or concrete floors. The product is easy to apply and helps visibly brighten gray or green-colored surfaces.

🔹 Dissolved in water (spray or pouring method)

1. Dosage : Dissolve 50–100 grams of iron sulphate in 10 litres of water.
2. Application : Apply the solution evenly with a pressure sprayer or watering can with a fine spray nozzle.
3. Application : Allow the surface to dry; rinsing is usually not necessary.
4. Caution : Do not apply in the rain or within 24 hours of precipitation.

🔹 Sprinkle dry on surfaces (for outdoor use only)

1. Dosage : Sprinkle 30–50 grams per m² on the dry surface.
2. Activation : Lightly mist with water to allow the product to react.
3. Preferably use in cloudy weather , with no bright sunshine or rain in the forecast.
4. Do not apply on or next to tiles and paving without protection – iron sulphate may cause brown stains

⏱ Application frequency

• For removing deposits or treating stone: 1 to 2 times a year , preferably in spring and autumn .
• Repeat if necessary, depending on the environment (damp or shaded areas may re-discolour more quickly).
