How can I achieve the best results when using grey wash stain on pine wood?

To achieve the best results when using grey wash stain on pine wood, start by sanding the wood to create a smooth surface. Apply a pre-stain wood conditioner to help the stain absorb evenly. Test the stain on a small, inconspicuous area of the wood to ensure the desired color. Apply the grey wash stain evenly with a brush or cloth, working in the direction of the wood grain. Allow the stain to dry completely before applying a clear topcoat to protect the finish.
