By using a product from the same range on each type of wood, that needs to be matched, you can obtain a closer colour match. Where possible, it is best to use a clear coating on the darkest wood and a coloured coating on the lightest wood. Oil is a good option because it penetrates well into the wood, colouring it and protecting it at the same time. With an oil, you can also apply a second coloured coat if the match is not close enough after the first attempt. Hard wax oil is a superior oil that is also available in colours. For example, to match new pine to old pine use 1 part whiskey hard wax oil to 1 part clear hard wax oil on the new wood and just clear on the old wood.
