Written By Dominic Auten

What is pine tar?

Pine tar is a natural wood preservative made by slowly heating pine wood in low oxygen, producing a rich, protective resin. It has been used for hundreds of years to protect wood structures, ships, fences, cabins, and outdoor buildings.





Why use pine tar?

Pine tar offers deep, long-lasting protection for exterior wood:

  • Seals and preserves wood fibers

  • Water-resistant

  • Helps prevent rot, cracking, and weather damage

  • Naturally resistant to insects and fungi

  • UV protective when mixed with natural oils

  • Non-toxic and environmentally friendly

  • Easy to Maintain

Unlike surface coatings, pine tar penetrates deeply, protecting wood from the inside out.
