How to thin stain for optimal application and coverage?

To thin stain for optimal application and coverage, mix it with a small amount of mineral spirits or paint thinner until it reaches the desired consistency. Test the thinned stain on a small, inconspicuous area to ensure it applies evenly and absorbs well into the surface. Apply the thinned stain in thin, even coats with a brush or cloth, allowing each coat to dry completely before applying the next one for best results.
