A method of tempering composite fiber panels eliminates a need for a bake oven during the tempering step. Both the front and back surfaces of the panels are sprayed with a tempering oil including a mixture of a drying oil and a dryer or catalyst. The drying oil may include a linseed oil refined to minimize low molecular weight and a conjugated oil. Sometimes the drying oil is further mixed with either a conjugated oil, a catalyst, a low molecular weight isocyanate resin (Imw-MDI) or another additive. The sprayed panels are stacked preferably in face-to-face contact inside a curing chamber heated only by the residual heat in the hot panels. A number of additives to the tempering oil are considered. A number of different forms of commercial panels are considered, such as: hardboard, oriented strandboard, fiber board siding, wafer board, medium density fiber board, particle board, and other similar boards.
