Antique Oak Lye has been specially developed to produce an ammonia smoked appearance to Oak wood. This product is user-friendly but corrosive and should be handled with caution during application. Since the product reacts with the tannic acid in the Oak, the colour after application may vary depending on the concentration of tannin in the wood. However, it creates a very unique colour and Vintage appearance. The final colour will first be achieved after 1-2 months.
