Imprex Light Pine Tar is now discontinued from the manufacturer. While quantities last.
This special, light-coloured tar penetrates into wood and takes on the quality of a glaze with time, giving a natural finish to the wood with very good water-repellent properties.
Imprex Light Pine Tar is made from pine tar, pure pine oil and pine oil pitch that is free from acetic acid, phenols, contaminants, and mineral products. It can be used for penetrating and protecting wooden surfaces on boats, shingled roofs, and wooden buildings as well as for oakum and rope preservation, among other natural fibre strands. Can also be used in certain veterinary applications where a reduced concentration of pine tar is desired. For wood preservation, Imprex Light Pine Tar must be mixed with linseed oil before use.
Over time and with subsequent applications, 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 Test Kitto help with learning the nuances of the material for staining and protecting surfaces and to ensure you achieve the desired result. Test how the material will look on your particular surface, and test application methods and strategies for your 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. See the Auson Technical Data Sheet below for more detail.
The approximate spread rate of this pine tar mixture is 60-100 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.
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.
Imprex Light Pine Tar is a product of nature that is viscous and sticky, where the viscosity may range slightly from batch to batch.
It is possible that water spots can develop on the surface, but these will disappear when the surface is once again dry. Mixing with linseed oil can help to avoid this.
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.
