WOCA Antique Lye is a lye specially formulated to achieve an antique patina look. The final result will be 100 % unique as the tannin content in the wood highly influences the look. The lye is often used to create a smoked oak look and since no ammonia is used, it supports green profiles. WOCA Antique Lye makes it possible to create desired high-end solutions when used in combination with WOCA oils. It can also be used in combination with WOCA Tannin Primer for wood species with low tannin content.
