It is ideal as a first basic treatment especially on woods with a high tannin content such as oak, walnut and cherry. Its characteristics allow an excellent adhesion on the wood making it an ideal base to prevent yellowing and the appearance of dark spots on the surface, especially in the case of water-based finishing cycles in light colors
