Iron vitriol gives patina and some protection. The iron vitriol powder is dissolved in hot water. The solution is applied to the wood with a brush. After a few months, the wood gradually changes color and takes on a gray shade, the stronger the concentration, the darker the wood becomes. Iron vitriol is an outdoor product and should not be used indoors. The treatment does not need to be repeated. You can add a bag (water-soluble silver stain), just to see where you ironed. The iron vitriol itself is uncolored and the gray comes later, but with the silver stain the surface becomes gray immediately and the "fake gray" disappears by itself. Sold as 1kg, 5kg and 15kg.
- 1 kg of iron vitriol
- Dissolves in 20 L of warm water
- Sufficient for approx. 40 square meters
