What are the best practices for applying indoor wood sealant to protect and preserve wooden surfaces?

To apply indoor wood sealant effectively, start by cleaning and sanding the surface. Apply the sealant in thin, even coats, following the manufacturer's instructions. Allow each coat to dry completely before applying the next. Use a brush or cloth to ensure even coverage and remove any excess sealant. Repeat the process as needed for optimal protection and preservation of wooden surfaces.
