RMP Pure Tung Oil is 100% pure, cold-pressed tung oil, with no hexane or additives, for a matte, water-resistant finish on wood, countertops and cutting boards and on unglazed stone, concrete and brick.
Once fully cured it's food-contact safe and meets FDA food-contact standards, so it suits butcher block, cutting boards and charcuterie trays. On dense woods, thin it 1:1 with Citrus Solvent or Pine Solvent so it soaks in, or buy it already thinned as Half & Half. It feels dry in 2 to 4 days, partly cures around day 10 and fully cures in up to 30 days. A light coat rubbed on tool steel also makes a fine rust inhibitor, which is how a can of it earns its keep in our shop.
RMP Finishes started in 1993 as D.O. Siever Products, a side business selling pigments that grew out of Dwayne Siever's antique restoration work in a renovated barn in Pennsylvania, and its Real Milk Paint followed in 1995. The family-owned company moved its manufacturing to Hohenwald, Tennessee, in 2014, and in 2025 it changed its name from The Real Milk Paint Co. to RMP Finishes.
