iron vitriol

Iron vitriol gives patina and a certain 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. Recipe: 1 kg of iron vitriol is dissolved in 20 l of hot water - sufficient for about 40 sqm. One can add a bag (water-soluble silver stain), solely to see where it has been applied. The iron vitriol itself is colorless, and the gray shade comes later, but with the silver stain, the surface becomes gray immediately, and the "fake gray" disappears by itself.

Organowood, an effective water-based wood protection product consisting of silica minerals and natural plant substances. The treated wood gains flame-retardant properties and improved resistance to rot.

Free from environmentally hazardous heavy metals, biocides, and solvents, classified as Good environmental choice by the Nature Conservation Association.

Treated wood gets a light, smooth surface that ages beautifully and over time becomes naturally silver-gray.

It is preferably used on terraces, docks, fences, wall panels, wooden furniture, etc., where you want a colorless surface.

For a full long-term protection, two products are used: first wood protection 01, then wood protection 02. 1 liter is sufficient for about 8-10 sqm.
