Red Pine Tar
Red Pine Tar is made from Genuine Dark Pine Tar with natural red oxide pigment added. The pigment gives a classic, matte red finish that is so traditional in Sweden for hundreds of years, and it is also finding popularity on modern structures, bridges, and any outdoor surface where a strong red colour is desired. Additionally, it protects the wood against the elements, including UV rays on surfaces strongly affected by the sun.
Pine Tar has a long documented history of being used to penetrate and protect wooden surfaces outdoors, while still allowing it to breathe. Mix with Purified Linseed Oil to create a natural, red wood stain, giving better penetration and a surface that finishes matte and less sticky.
Application:
Apply Red Pine Tar to new, untreated wood or to wood that was formerly treated with Pine Tar, or distemper paints such as Falun Red.
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.
Pine Tar comes concentrated, and there are many old recipes for dilution, but 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. 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.
Note: Red Pine Tar is a product from nature, where the appearance may vary slightly from batch to batch. For larger quantities, it can be a good idea to mix several cans together for better uniformity.
