Processing instructions Arrange the parts to be fumigated, in a distance to each other (in a closable room - e.g. a room made of partition walls coated with PE foil). Remove all metallic parts before. Pour ammonia into a big enough, flat plastic bowl and close the room. Let vapours act upon the wood until the desired colour depth is reached. Before application of the lacquer, air the parts well for several days in order to expel excess ammonia gas.
Particular instructions Chemical stains react with the wood contents. Depending on the areas where the woods were grown, when they were cut and the like, their tannin content varies and can lead to different colour developments. Only use tannin-rich European white oak. Sapwood, red oak and many American oaks are not suitable due to the low tannin content.. Do not spray or brush material! Please ask for our separate Technical Information on this topic.
General instructions on workmanship Protective equipment: rubber apron, rubber gloves and eye protection!
