Annie Sloan Soft Wax comes in clear and dark and is very easy to apply. I would recommend waxing every piece of furniture once completed. Some people prefer to sand and then wax others like to wax and then sand. This I feel this is a personal preference. Wax is water repellent and has no odour.
Apply dark was to age your piece. Always clear wax your piece first and then dark wax. If you find you have used too much dark wax, simpy remove by adding more clear wax.
