Hi, Katerina. Maybe it just seems like I answer this a lot but it is a real common question. At www.citristrip.com, go to "Ask the Experts", then check the threads "stripping structural beams" by Nancy on 2/7 and "wood stains" by Roy on 1/28. Wood is wood and it does not matter much what it is made into, the process is the same.
Let us know if you have any questions and good luck. Henry in MI
