Instructions for use
For wood preservation, Imprex should not be used unmixed, a recommendable mixture is one third each of Imprex, boiled linseed oil, and turpentine. This compound gives a particularly light shade of tar to the wood. Make sure that the wood is absolutely dry before you tar it.
Imprex can also be used with transparent colour pastes for making wood stain. As any other Pine Tar Imprex will fade by the sunlight, it should be applied with a brush in thin layers. During rainy weather white spots may occur. They will disappear when the surrounding air is dry enough. Add linseed oil to avoid this.
