What are the best techniques for applying water-based stains to wood surfaces effectively?

The best techniques for applying water-based stains to wood surfaces effectively include preparing the wood by sanding it smooth, applying a pre-stain conditioner to prevent blotchiness, using a brush or cloth to apply the stain evenly in the direction of the wood grain, and wiping off any excess stain to achieve the desired color intensity. It is important to work in small sections and to allow the stain to dry completely before applying a protective finish.
