BLACKBARRIER
Natural Tar · Wood and Metal Protector
A 100% natural, viscous, dark-coloured wood tar with a distinctive odour, obtained through pyrolysis of organic agricultural waste (such as olive pits, walnut shells and apricot kernels). It gives wood and metal surfaces both physical protection and biological resistance, and is an eco-friendly alternative to chemical-based surface protectants.

What is BLACKBARRIER?
BLACKBARRIER is a natural, viscous, dark-coloured wood tar obtained through pyrolysis of organic agricultural waste such as olive pits, walnut shells and apricot kernels. It gives wood and metal surfaces physical protection and biological resistance: it repels water, prevents corrosion and deters insects. It is used on fences, barns, storage tanks, agricultural machinery and the underwater hulls of boats.
Penetrates wood, coats metal, repels water.
Used to give wood and metal surfaces both physical protection and biological resistance.
Wood preservative
Fences, barns, vineyard houses and agricultural structures.
Metal protector
Storage tanks, structural profiles, agricultural machinery.
Insect repellent
A natural deterrent against woodworms, moths, termites and similar pests.
Anti-corrosion
Forms a protective film on metal surfaces, especially in humid or marine environments.
Water repellency
Enhances durability against outdoor weather conditions.
Marine vessels
Used on the underwater hulls of boats, dinghies and fishing vessels as a biological protective coating against barnacles, algae and marine borers. Creates a traditional, natural anti-fouling layer on wooden boats.
Resins coat, phenols protect.
The resinous fraction, 60–70% of the product, provides coating, water repellency and long-term protection on the surface. Phenolic compounds (2–5%) add antiseptic and antifungal properties, and aromatic hydrocarbons help it penetrate wood and repel insects.
Qualitative composition (ingredient list)

Waterproofing, biological resistance and anti-fouling.
The phenolic and aromatic compounds in wood tar deeply penetrate surfaces, providing both waterproofing and protection against biological degradation. Studies have shown that these natural tars exhibit anti-fouling effects against marine organisms (Kakuta et al., 2020), helping protect submerged surfaces from biofouling. It is also a non-toxic yet effective insect control solution for agricultural structures.
