The Daler Rowney Turpentine is a highly refined, traditional artist-grade solvent formulated to thin oil paints and create lean, quick-drying washes in the early block-in stages of a painting. It breaks down the natural viscosity of oil colors to improve paint flow and enhance delicate layering control without compromising structural adhesion. This premium fluid evaporates cleanly from the paint film and functions as an exceptional, residue-free cleaner for studio brushes, palettes, and palette knives.
