What are the best techniques for applying MDF stain to achieve a professional and durable finish?

To achieve a professional and durable finish when applying MDF stain, it is important to properly prepare the surface by sanding and priming the MDF. Use a high-quality brush or sprayer to apply the stain in thin, even coats, allowing each coat to dry completely before applying the next. Seal the stained MDF with a clear topcoat for added protection and a polished look.
