Ronseal Colron Refined Wood Dye in Deep Mahogany is a deeply penetrative wood dye featuring light-fast pigments to ensure the colour won't yellow over time or fade in exposure to sunlight. Designed for use on interior wood, the more coats applied, the more intense the colour will be. This product is designed to allow for colour matching and should be applied with a cloth. For best results, it is designed to be protected by Colron Refined Interior Lacquer.
