Before applying varnish to oiled wood, it is important to take some precautions. Oil recipes vary among manufacturers, which can make some incompatible with quality varnishes or lacquers. In particular, wax is an ingredient that should never be present in an oil that will be varnished, as it is completely incompatible with varnishes and lacquers.
You will need to make sure that the products being used are compatible.
Thank you. The product I used was Tung n teak oil Circa 1850. There is no wax or varnish in it. But has some solvents. Do I need a sealer before pre-cat lacquer?
