RMP Dark Half is Dark Tung Oil pre-mixed with natural, food-grade Citrus Solvent, ready to use from the can, for a penetrating matte finish that deepens the grain and gives wood an aged look.
Apply it until the wood stops absorbing, let each coat soak in up to 40 minutes, wipe off the excess and let it rest overnight; three to five coats give full saturation. Keep heavy objects and standing liquid off it for the first 7 to 15 days; it fully cures in 15 to 30. Use it on raw wood only, not over polyurethane, shellac or another sealed finish, and apply it above 50°F. Once fully cured it's suitable for food-contact surfaces.
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.
