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 over 1000 years to protect and preserve wooden buildings, boats, jetties and everyday items 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.
Over time and with subsequent applications, as natural material wants to the colour tone of the surface will fluctuate somewhat between warm amber tones and a darker, aged, grey-brown patina as it is exposed to UV light.
Before diving in, use thePine Tar Intro Kitto help with learning the nuances of the material for staining and protecting surfaces as well as for testing application methods and strategies for a particular project.
Apply Pine Tar to bare wood or to wood that was formerly treated with Pine Tar or natural oil, such as Purified Linseed Oil.
Clean the surface with Linseed Soap and water to remove dust and dirt from the wood with a brush. Rinse well and allow to dry.
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 apply 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.
The approximate spread rate of this pine tar mixture is 100 sqft per litre, depending on the mixing ratio, density, smoothness, and overall condition of the substrate. It is also important to consider the environmental conditions. See the Auson Technical Data Sheet below for more detail.
Minimum operating temperature: 10 - 15ºC on the surface and in the air. Beware of invisible condensation on surfaces below 15ºC.
Raw Linseed Oil is a deep penetrating oil that is slow to dry. It must be well absorbed by the timber and is well suited to most projects, including wooden facades and roofs. Boiled Linseed Oil is a drying oil that can become hard and form a film on the surface after several coats and is well suited to projects where a faster drying time and harder finish is desired, such as walked-on surfaces.
Genuine Pine Tar is a product of nature that is viscous and sticky, where the viscosity may range slightly from batch to batch.
Achieve a surface with a rich, dark, aged patina right away by pretreating with a reactive wood stain such as LifeTime Wood Treatment, and then proceed to apply Genuine Dark Pine Tar and Linseed Oil for long-lasting and nourishing protection.
