Description
Grey Pine Tar Vitriol is made from Genuine Dark Pine Tar with iron vitriol and natural grey pigment added. The pigment gives a stylish, modern, matte grey finish that is ideal for wooden buildings, fences, boat houses, and any outdoor surface where a stylish grey colour that blends in with nature is desired. Plus, 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. This product is already pre-mixed with a high-quality gum turpentine to give better penetration and a surface that finishes matte and less sticky.
Testing
Before diving in, use the Grey Pine Tar Vitriol Test Kit to 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.
Application
Apply Grey Pine Tar Vitriol to new, untreated wood or to wood that was formerly treated with plain iron vitriol.
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.
Grey Pine Tar Vitriol comes diluted with a high-quality gum turpentine, so it is ready to use right out of the can, and mixing with linseed oil is not necessary. This helps to promote penetration into the wood for a long-lasting result. Stir well before use to ensure the pigment is well mixed.
The approximate spread rate of this
premixed Grey Pine Tar Vitriol is 60-100 sqft per litre, depending on the 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.
Drying can take from several days to several weeks depending on the weather and other environmental conditions as well as on the condition of the surface and its porosity.
Note
Grey Pine Tar Vitriol 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.
