Oil paints are paints whose solvent is organic (gasoline, white spirit, aromatic ketones …). There are different types of oil paints, the main ones being glycerol paint, epoxy paint, and polyurethane paint.
Oil paints are resistant and can paint different surfaces inside and outside (ceilings, floors, woodwork …).
