What Are the Advantages of iron vitriol？

Iron vitriol gives patina and a certain protection. Iron vitriol powder is dissolved in hot water. The mixture is applied onto new timber with a paint brush. After a few months, the wood is gradually changing color and assume a gray shade - the stronger the concentration, the darker wood. Iron vitriol is an outdoor product and should not be used indoors. Treatment need not be repeated.

Recipe: 10 lb of Vitriol powder dissolved in 24 gallons of warm water is enough for about  sq ft of surface area. You can add a small amount of the light or dark pine tar to the solution as well as some organic raw linseed oil. The organic raw linseed oil added will prevent the wood from cracking. The organic raw linseed oil will darken the color.
Great variations can be created by adding more or less of the light pine tar and organic raw linseed oil. Iron Virtriol itself is colorless so the gray color comes with time.
This is an effective and very economical water-based wood product composed of minerals and natural plant substances. Wood treated with iron vitriol(fr,kk,ko) has flame retardant properties and improved resistance to rot.
Free from hazardous heavy metals, biocides and solvents classified as Good environmental nature protection.
Treated wood gets a bright, smooth surface that ages beautifully with time aging to a natural silver-gray.
Ideal for use on wood siding, decks, docks, fences, wall panels, furniture etc.
Always do a test to avoid unwanted results on you final project.

Of late there has been significant interest in the rekindling of time-honoured wood finishes. Many of these surface finishes are experiencing a renaissance in a world where natural materials are increasingly desired. Surprisingly, many of them perform better than modern alternatives.

Iron Vitriol / Iron Sulphate

Iron sulphate has been used for generations as a surface treatment to create the impression of a weathered wooden façade that has turned grey. Iron sulphate reacts with tannins in wood and causes a chemical colouring on the surface of the timber.

Iron sulphate is generally mixed with water and is a colourless liquid that is painted or sprayed onto the sawn face of new wood or wood previously treated with iron sulphate.

Over time, treatment with an iron sulphate solution turns the timbers surface an attractive and lasting brown-grey to silver-grey colour, depending on the species of timber used. The wood should be treated before being installed, as this gives better penetration on the tongues and grooves.

One of the benefits of iron sulphate is that it “self-healing”, generally cracks and damage to wood will be naturally resealed by the stain.

Iron sulphate is low toxicity and generally does not contain volatile organic compounds (VOC’s).

Abodo’s Vulcan is an excellent substrates for iron surface based treatments.

Layers of silicate crystals grow deep in the wood, providing a barrier and a resistive protection against fungus, vermin and microorganisms trying to gain a hold.

Modern versions of silicate based wood coatings now perform better. While older methods relied on large silicate molecules, the ones used in Abodo’s Sioo:x coating are smaller. We have also substituted sodium as a helping agent, for potassium. The advantage of the Sioo:x solution is that it quickly penetrates the wood and combines with it.

Abodo is at the forefront of modernized ancient wood protection techniques.
