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.
Imprex Light 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.
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.
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.
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.
Minimum operating temperature: 10 - 15ºC on the surface and in the air. Beware of invisible condensation on surfaces below 15ºC.
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.
Imprex Light Pine Tar is a product of nature that is viscous and sticky, where the viscosity may range slightly from batch to batch.
