Genuine Dark Pine Tar
Genuine Dark Pine Tar is the mother of all the pine tar products. It is produced by slowly burning the resin from the root stock of pine trees, giving it a distinctive, lovely smoky smell. Pine tar has been used in Scandinavia for hundreds of years to protect and preserve wooden buildings, boats, jetties and everyday items. As well as protecting wooden structures against rot. Natural tar is also mildly antiseptic and even has a long history in veterinary, medical, and personal care applications.
Genuine Pine Tar is used for the preservation of wood outdoors such as cottages, splint roofs, boats, bridges, and more. It is also recommended for the treatment of wooden church roofs and other cultural buildings made of wood. The Pine Tar can also be used on animal hooves and other veterinary applications. It can also be used for making soap and personal care products.
This original form of pine tar is sometimes also called Stockholm Tar, as it was the largest export product from Sweden by the end of the 18th Century and through the 19th Century, and it was an essential material to many industries, including naval and merchant shipping concerns all over the world.
Genuine Pine Tar has a dark colour from the ultra-fine carbon particulate of the burning process, and it contains all the elements of rosin and fatty acids and their conversion products such as rosin oil, oxidized acids, esters, high-boiling terpenes, and fatty alcohols, which characterizes a pine tar of high quality and excellent protection according to traditional knowledge.
Application:
Genuine Pine Tar comes concentrated and can be applied on its own or diluted. There are many old recipes. For most applications on wood, we like to mix 50/50 with Purified Linseed Oil and applying the mixture warm (approx. 60ºC) and to a warm surface in order to avoid the need for solvents. This helps to promote penetration into the wood for a long-lasting result. Adjust the ratio according to your project. See the Auson Technical Data Sheet below for more detail.
Clean the surface with Linseed Oil Soap and water to remove dust and dirt from the wood with a brush. Rinse well and allow to dry.
Minimum operating temperature: 10 - 15ºC on the surface and in the air. Beware of invisible condensation on surfaces below 15ºC.
Note: Genuine Pine Tar is a product of nature that is viscous and sticky, where the viscosity may range slightly from batch to batch.
