Abstract
Water-based stains are based on an oil-in-water emulsion having a binder that includes, consists of, or consists essentially of drying oil combined with a non-aqueous polymer dispersion. The compositions can be tinted using traditional water-based pigment dispersions, yet the overall hydrophobicity results in minimal interaction with the polar cellulosic structure of wood.

(canceled)
A method of making a wood stain composition, the method comprising the steps of:
- forming a first mixture by combining drying oil and a non-aqueous polymer dispersion;
- forming a second mixture by combining water and a surfactant;
- adding the first mixture to the second mixture to form a third mixture, and mixing the third mixture until a smooth uniform state is achieved.
