Not to be confused with traditional oil finishes, OSMO Polyx-Oil is an engineered low VOC finish made with natural plant oils and waxes, plus just enough highly refined mineral spirits to allow easy application. This finish offers excellent durability and renewability with a unique lustrous finish. It will never crack, blister or flake off. Instead of forming a plastic film, like polyurethane does, OSMO Polyx-Oil has open pores that “breathe.” This allows any moisture that does get through to get back out again without pushing off the finish. Because it is micro-porous, Polyx-Oil works well in rooms with high humidity, such as kitchens. It meets German standards for resistance to stains from wine, cola, coffee, tea, fruit juice and, of course, beer.
